Clean Power Trailers = Off Grid Life n Biz

Mobismart Clean Power Trailers

or “CPTS” will replace the typical Diesel Power Trailers we currently use to backup our homes in off grid situation temporary or permanent.

The Question is When?

The answer is:   Now, and especially in 2018 and beyond.


The Reason? Energy Storage has arrived


Energy Storage has arrived because Battery Power Density has increased 2X  twice in the last 4 years in terms of price/performance with:

Significantly lower prices on traditional deep cycle (50% depth)  lead acid/gel/matt  3000 to 4000  re-charge cycle technologies trying to compete with newer,  longer life (6,000 to 11,000 cycles) Lithium Polymer offers with similar or better energy density but higher sticker prices which continue to drop putting the price squeeze on traditional lead acid battery manufacturers.

A New Breed of  micro Hybrid Clean Power Stations in Mobile Form has arrived:

The Mobismart Clean Power Trailer, a sneak preview.. coming soon in 2018

Mobismart CPT w Starwind5 4kW NP 2017-11-02 17-15-08

WARNING!!!- Do not read this blog if you a numbers averse. 🙂

Now that the Mobismart Clean Power Trailer is about to make its debut in 2018, let’s take a deep dive into the numbers to see why this exciting new Clean Power Solution  offered by as a turnkey,  “hook it up, tow it to where you need it,  just deploy in a few minutes and  plug it in , and  it works right away” offers tremendous value  for   both  power generation and energy storage needs of anyone looking to get off grid.

First and foremost, the Mobismart CPT  will work where ever or when ever you need it, rain, wind, shine, in  -50C or +50 C weather conditions. (That’s right the has some really nifty  patented active battery thermal management built right in to make sure you get optimum power production and battery  performance, all the time regardless of the environmental conditions outside the trailer). Having said that, you do need to option the CPT from Mobismart at time of order to meet the needs of your planned off grid site, and you will probably wait 8 to 12 weeks to get your CPT, as Mobismart produces each CPT to the customer’s exact order specifications, within the available generation types, sizes and  energy(battery)/fuel storage options offered. Think of the Mobismart Clean Power Trailer ordering experience  like ordering  and financing a small RV  for your exact site specific power needs and you will get the picture (trailer hitch spec option included.)

Second the Mobismart CPT has built in twin axis control to track the sun accurately for maximum solar conversion all the time.

Third the Mobiwind 4kW Wind Power Generation sub system can be trailer mounted or separate mast mounted ( @ about 35% for the tip up tower mast, as a percent of the cost of Wind Power Generation module, predicted to be US $ 10,000 MSRP)  to suit your local site needs.

Fourth, if your site and application requires it the Mobismart CPT can be easily integrated into an existing Diesel Power Trailer to semi-retire it to generation of last resort (to reduce your carbon foot print and avoid most carbon taxes)  or combined with a new fuel powered generation sub system of your choice as certified or offered by Mobismart to be used a a full backup of last resort, or as a trickle charge system.

Fifth, your choice of battery tech , depth and cycle life from proven list of battery leaders in the lead acid/gel/matt space or the Lithium Polymer space.

Sixth, order the CPT the weay you like it, only an 8 to 12 week lead time to get the CPT exactly your way, ready to be picked up, towed to your site and plugged into your site power use.

Seventh, and last if not most important, Mobismart  CPTis a very bankable solution which will easily qualify for bank or lease company rates under normal terms, as the suppliers of components are well known and reliable, which also ensures an after market for your Mobismart CPT should you sell your site or the CPT itself later on due to life or biz changes. Expect a return on your investment, that is the CPT paying for itself in 3 to 5 years if properly sized to your power requirements and needs for power reliability.

Mobismart Options.

The Mobismart  CPT  “Clean Power Trailer” solution is sized and priced to meet most everyone’s  small business; remote work site  or; residence off grid needs and can be ordered configured with Solar only, Solar & Wind, Solar Wind and  co-generation or any of the above with an optional  trickle charge configured  internal  combustion engine with 60 gallon fuel tank ( the latter two ICE options only for use on non roof top configurations  which must be placed out in the field, yard,  or outside a building with proper ventilation/exhaust). These ICE CPT options may be necessary for mission critical backup and make the CPT less clean, however they are last resort or “must trickle charge” options only, capable of running on propane, natural gas, or regular gasoline, and if necessary even  dirty marine grade or farm diesel.  There is even a Mobismart option to integrate with existing diesel power trailers to “semi-retire” the latter into duty  a last resort use configuration, to squeeze the last bit of useful economic life out of your existing diesel power trailer.

Significantly for the larger work sites and small businesses, it is also possible to daisy chain the Mobismart Clean Power Trailers together to deliver up to 110 kilowatt Name Plate Generation matched to what ever you feel your energy storage (battery capacity) might be, as the CPT can also be configured as a slave system with only batteries and solar panels, hooked up to other CPTs in a redundant mesh, where at least two of these CPTs have the master controllers, basically a communication equipped PLC “Programmable Logic Controller” from a well known and trusted PLC vendor.. (ie Siemens, Mitsubishi, Schneider/Xantrex, Omron, Rockwell/AB , etc, you can spec what PLCyou like to fit your existing business and operations model for your distributed off grid energy sites and staff expertise).

The Mobismart CPT dance with Diesel Power…

What the new Mobismart CPT  means is one can power their future off grid energy requirements with clean generation  elements, all of which  are priced competitively  in comparison with  Diesel Power Trailers,  as far as Level Cost of Energy is concerned  “LCOE” ( LCOE means including in the solutions complete life cycle and disposal costs factoring in applicable of rises in the cost of fuel and carbon taxes over a 20 year useful life asset)  as follows in US $, when we look at the Mobismart equipped with a 2.2kW of Solar Generation, 4kW Nameplate Wind Generation, a 3kW backup Internal Combustion Engine “ICE” and 70k Whrs of Battery Storage with a 60 US Gallon Fuel Tank (good for 24 hours):

A Typical  “All-in ” Solar/Wind/ICE configuration off the Mobismart CPT might be 

Capital Expense  (As part of CPT)                                                                        Cost/W (MSRP)

2.2 kW Solar Generation (standard with all Mobismart CPTs)                               1.50

–  As part of Total CPT Sticker price est. = US $3300.00

– Maximum  AEP efficiency @ 1100am-1pm is 14% of Name Plate

4kW Wind Powered Generation  (option with all Mobismart CPTs)                     2.50

– As part of Total CPT Sticker price est. =  US $10,000

– Maximum  AEP average/hr is 30% of Name plate properly sited

– Add Tower @ 15m with screw pile mount @ 35% of Wind Gen        .50

5.5kW Onan 5.5HGJAB-6755 RV GENERATOR (Popular RV Gasoline)                    .88

– As part of the Total CPT Sticker price est. = US $5600.00

– using  a 60 Gallon Fuel Tank  ( which adds about US $+.10/Watt)


Total CPT  Capital Expense  Generation Cost/W   installed   ===>                 $5.88


What this means is expect  2.2+4+5kW of Name Plate capacity  – 11.2kW NP to  list in the US Market for around $70,000 including storage.

So think of  acquiring Mobismart CPT off grid freedon as powering your house for the same 8 year leased price of an expensive SUV,  which is more than than worth it anyway you shake it, especially if you are a prepper with more insights to the impending economic bust and fall out predicted than the average bear!  If your not a prepper but your  power use application is off grid and you are looking for a reliable clean power source with minimal amount of long term maintenance and fast return on investment, then the CPT certainly fits the bill.

Energy Storage Performance where art thow? And what art thow? 🙂

Energy Storage price performance of CPTs is best measured for capital expense purposes and securing a loan at the bank expressed as Cost/kwhr over the useful life before replacement which should always exceed the warranty period offered by at least 20%.


Energy Storage with 12 year Useful Life (10 year warranty)

Energy Storage  Lead Acid Gel/matt (one of several battery options)                 .10

-operating at 50%draw depth with 4000 cycle life (more required)

– more weight than LiPoly,  less capital cost up front,

– requires 7 year one time   switch out if heavily used

– use if your CPT  deployed as a short term worksite power source

Energy Storage Lithium Polymer                                                                                .13

-operating at 90% draw depth with 9000 cycle life (fewer required)

– less weight, higher up front capital cost, longer life

– longer to get to BE , howver longer life

– use if the site is permenant deploy and forget w/ zero site mainteance

CPT Fuel Cost for  ICE Generator of last resort with co-prime mover (able to handle the entire load) . Oil price dependent.

Predicting the cost of ICE Fuel over the next 12 years is always a  best guess , so lets stick with expert advice that sees the price of a barrel of oil going 2X from current Fall 2017 rates to about $100/barrel by 2020, so that takes care of the first 2 years of useful life for comparison purposes, and lets be kind to Oil and Gas and say the barrel price will  gradually rise to 2030 levels of US $ 150 per barrel. Using this reasonable assumption, lets assume we have 10 days per year in which we run the Diesel Generation as a co-primer mover because we don’t want ever to be without power for everything regardless of global dimming and still day “no wind” impact at our off grid site, be it our home, cottage, work site or small business location.      Here is what the Total Operational Cost fo the ICE co-prime mover would look like using gasoline only. Lets assume we never have to change a spark plug as the system will routinely run weekly for a short period to keep all  ICE gaskets lubricated so they don’t dry out to avoid a refurbishment charge of the ICE. (Do typical part time regular “RV like” use of the ONAN Genset for which there is a lot of useful information from use on the web which help quantify the Opex cost of the ONAN ICE gasoline version), all numbers below . We have used the  following Link Canada’s Energy Future to back up our own CPT forecast, with info below expressed in Canadian Dollars, given is a Canadian Company hailing from Toronto, Canada:

         Fuel Cost/L            Fuel Use  (24hrs*10 days)        Delivery/  Maintenance Costs    

Year 1           1.00                           $240                                    4 times @ $20.00 = $ 80.00

Year 2          1.05                            $252                                       4 times @ $20.00 = $ 80.00

Year 3         1.10                            $264                                   4 times @ $20.00 = $ 80.00

Year 4        1.15                             $276                                   4 times @ $20.00 = $ 80.00

Year 5        1.22                           $292.80                                   4 times @ $20.00 = $ 80.00

Year 6        1.30                           $312                                   4 times @ $20.00 = $ 80.00

Year 7       1.39                            $333.60                                   4 times @ $20.00 = $ 80.00

Year 8      1.50                             $360.00                                   4 times @ $20.00 = $ 80.00

Year 9       1.61                           $386.40                                   4 times @ $20.00 = $ 80.00

Year 10     1.73                         $415.20                                   4 times @ $20.00 = $ 80.00

Year 11    1.85                          $444.00                                   4 times @ $20.00 = $ 80.00

Year 12   2.00                           $480.00                                   4 times @ $20.00 = $ 80.00

Totals                                       $4056.00                                   $960.00

Total Fuel Cost over 12 Year evaluation period for CPT  = $5016.00

The REAL  Levelized Cost of Energy  LCOE production using of ICE over 12 Years simply as a 10 day last resort co-prime mover?

Capex  of US$ $5600 (installed and integrated) + Opex (adj. to US $ @ .80 CDN) US $4012.80  = US $ 9712.80

Then add the adjusted  8% interest  the bank wants for interest on your 1 year  short term loan  if you purchased  the ICE system separately or as an add on item through a 3rd party  so lets say  you  paid US $350.00 in interest for a grand total of:

So you will need to spend US $ 10062,80  for the privilege of a 100% guarantee your CPT is always on for mission critical work site, small biz or family lifestyle support. 🙂

That said, the financing of a bankable solution such as the made up of reputable components, controllers and materials,  will probably fall into an RV like lease  rate of 8% paid out over 8 years , which is after discount or 0% lease rate at MSRP which is typically the case these days. So the 350 interest charge might also be considered  a small sticker price at discount for those who subscriber to Zero interest offers from vendors.

When looking at the ONAN ICE (gasoline)  generation  Capex to Opex Ratio (including interest) we get the following:

US $ 5600/$4362.80  =  1.283579353  or  looking at a simpler way it says my  ICE Capex is  55.65% of the total LCOE  and the ICE Maintenance including interest is likely 44.35% of the LCOE over the 12 year evaluation period of the asset  (before any long term refurbishment is required, ie- ICE overhaul and tune up @ Year 12), which is not bad for a part time 10 days a year energy generation and fuel storage asset, provided you think your business or situation really demands that type of  “business continuity)insurance  and you cannot afford to be without power across all your needs for a single hour.

So if we evaluate the ICE generation component on its own in terms of true LCOE in Cost/W terms for generation we can see that the actual number, including fuel, interest charges and maintenance given the “RV style” ONAN ICE system we are looking at is 5.5kW Nameplate which represents the  ICE true cost/W as configured and used 10 days per year (2.74% of the year as a full time producers covering all needs)   is really  5500watts/$5600 US  Cost/W .98 cents plus the Fuel tank of .10/Watt  (US $ 550.00)   or  really all in  Cost/W is US $1.10 for the ONAN ICE Generation capex spend.

Now applying a bit of number magic, the utilization rate  of the ICE as a contributor to overall AEP “Annual Energy Production” is really only 2.73% per year  which = 240 hours running the ONAN ICE generation system at  a rate for what the house, biz site or work site needs which is typically recommended by the vendor of such equipment to be a 50- 60% rate or 2.75 to 3.3kW power output of the total 5.5kW  ONAN Name Plate capacity for the Model in question,  so  we can expect the ICE asset  to last 15 years before refurbishment/overhaul  or retirement  of the ICE generation conmponent is required ( a 15 year term is typical of the accounting Capital Cost Allowance Schedule  write off scheme used by anyone   such power generation equipment in the US/CAD or EU economies as dictated by the current  Federal/State/Provincial  tax regimes.)

Mobismart Wind Solar and ICE Power Generation, How do they compare?

So how does the Mobismart  ONAN 5.5kWatt ICE option  as we have specified at order time really stack up to the Clean Power Generation components provided Solar (Canadian Solar  is the standard offer) and Wind( The Mobiwind option design licensed for manufacture from Starwind5-  optioned only if the site will support it) versus say adding a slave Mobismart CPT with additional batteries and solar only? Well let’s have a look:

Generation Component:     Cost/W  as used    Efficiency     Cost/W 365days*12 Years

Nameplate                               US$                           of NP                 AEP   Adjusted Efficiency

2.2kW Solar Generation         1.50/W                   14%                              1.50/Watt

4kW Wind Generation            3.37/W                  30%                               3.37/Watt

-15m tower included (@35% of Wind Gent Capex)

5.5kW ONAN ICE (Gasoline)     1.08/W                30%

= assuming  365 days worth of fuel for 12 years running 100% of the time

wait for it…

A whooping  US $146,438.00  (ouch)

you will spend on just fuel to run the ONAN 100% of the time at 60% capacity or a continuous 2.2kWhr over the coarse of a year, every year for 12 years

That’s a little over US $1000.00 per month for 12 years,  a bit more than tad over what you spend on your SUV or pickup driving back and forth 20 days per month to and fro from work.

An then there is cost the Carbon Foot print of the ICE…,

ICE -Carbon Foot print has not been factored into the cost, as each regime applies it as a tax and credit differently, with Canada, the home turf of Mobismart  set to introduce same in 2018 across all businesses, institutions and residences using non-renewable carbon based fuels to generate electricity. In Canada the Carbon tax like in many jurisdictions is based on rate charge Carbon emission tonnage per year for each type of generation based on its vendor labelled Name plate capacity. (The accountants and tax lawyers are cheering!)

Incentives… oh my what a nasty web THEY weave…

The powers that be at the Municipal, State, Provincial, Federal and even regional level offer a dizzying array of incentives to offset your investment in clean power generation and storage (More cheers from the accountants and lawyers!) Ultimately, if you decide to take the incentive plunge be ready to commit the hours it takes and the upfront dollars to extract they benefits from such parties .


So how much does the Clean Power Trailer weigh and how much towing power do I reliably need to get the CPT to and from my site? Well depending on how one configures and orders the CPT, the weight will vary from a minimally configured (75% less battery storage than the standard offer of 75kWhrs at 2kW continuous output) 1.5 tons to a maximum of 2 tons(imperial 4000lbs) which offers the same 2kW continuous output.

Need to understand if you can tow the CPT with your current vehicle?

Check here  the 2017 towing guide in pdf form .

Chances are if you have a decent SUV or Pickup, you will be able to tow the Mobismart CPT whenever and to where ever you need it, any time.  🙂

Is CPT right for my off grid application and power needs?

Do know justifying off grid power also needs for comparison sake that you also need to  factor in the cost of getting power to the site and the cost of power annually and its forecasted rise over the next 12 years, before you have all the fact in front of you and can make an educated financial decision of whether or not the Clean Power Trailer is for you.

Chances are it will be, now that the price/performance of batteries has arrived at new attractive levels for the average consumer and small business, and also the fact does indeed have the smarts built in to optimize the use of your local free solar and wind energy resource and convert those natural clean sources of power into a fast return on your investment, in three to 5 years, without the use of the ICE option if you size and design your power needs correctly for your off grid site to fit within the Mobismart’s power output  and energy storage capabilities.
