Energizr & Gridz: Energy Storage Solutions From JLM Energy

JLM Energy, based in Rocklin, CA, is selling complete home (Energizr) and commercial (Gridz) energy solutions, with each one utilizing a battery system and a backup generator, including a grid connection. JLM generously answered my questions about its systems for this CleanTechnica article.


1. What is the size of the solar panel systems in watts or kilowatts that your products work with?

On the residential side of our business, a single Energizr can support approximately 6 kW of solar PV. For larger systems, multiple Energizr units can be used (up to 4 units in parallel).

On the commercial side of our business, using our Gridz system, we have customers that have installed PV systems as large of 1.2 MW.

2. Same question for the energy storage system.

Each Energizr™ inverter can provide up to 4.4 kW of instantaneous power.

The associated LiFePO4 self-contained battery pack systems have 8.8 kWh of storage capacity.

Multiple Energizr™ units can be installed in parallel, supporting up to 4 units at a time that are capable of delivering 17.6 kW of instantaneous power. Additional battery pack systems can easily be connected to the self-contained unit. As such, the kWh run time capabilities are vast.

With Gridz, our largest deployed storage capacity is 600 kWh.

3. How many units do you anticipate selling in the next several years?

JLM Energy forecasts 50 units per month in 2015 and 150 units per month in 2016.

30 systems in 2015; 100 units in 2015.

4. Who is your ideal customer?

JLM Energy has both residential and commercial/industrial clients.  Our ideal customer is excited about energy independence and has possibly taken steps towards that goal.

5. Some other key points

Most people who have invested in PV solar today don’t realize that their systems cease to function in the event of a grid outage. With Energizr, you not only have access to the clean energy stored in its batteries during such an event, but your solar system will stay on and continue to power you home and recharge the batteries for as long it takes before utility power is restored.

Each system comes with a 10-year warranty. A DIY version costs $7,495, which includes $7,500 in local state incentives, according to JLM. If the company installs the whole system, the cost is $12,495, including the same incentives.

The cost of solar power has dropped dramatically in the last several years. What will make it even more appealing is whole system packages like this one that include energy storage, so excess electricity can be stored and used at night or on cloudy days, that beat the price of electricity from the grid.

  • Wow. Now we’re talking. This is an off grid dream come true. If…some obscurities can be cleared up. The price of $7450 is for what? For PV and battery and generator? or just the battery unit? Actually that price would be in line with German prices for Lithium battery units of 8.8 kwh alone. If it is, it is still too expensive for U.S. markets. If it means the whole package of generator, battery, panels, inverter, then it is too cheap to be believed. The web site is beautiful but nevertheless obscure. It will obviously take some phone calls to get to the bottom of this. Please share on cleantechnica if you do get the details.

    • Hi-Thanks for the input…please see details in the discussion thread which will hopefully answer some of your questions.

  • Let the lawsuits over the name begin…

  • The cost figures sound too good to be true. Please dig a little deeper to get an accurate comprehensive analysis

    • This is just for a smart inverter and a battery which is what keeps the price down. Panels are extra.

      • Thanks! That sounds more like reality

      • So the inverter at 4kw is worth about $2500. The batteries at 8.8kwh are $5000. Getting there, still a bit high for lifepo4, considering Balqon will sell you 9kwh with battery management system for $3500. Now, they say “$7490 including $7500 state incentives” I presume that means the system really costs $15,000! Somewhat more than twice what it should cost if, if, if, they are only talking about inverter and batteries.
        Let’s put it this way. Top quality 4 kw inverters for on or off grid go for $2500. Balqon (California company) 9kw lifepo4 go for $3500. So $6000 before any rebates. That is DIY but so is the above price AFTER rebates! Well, maybe we are only partially informed (although that is why full pricing analysis is useful if they actually want to sell something!), but it doesn’t look good from first appraisal.

        • There was the mention of backup generator too, although not sure if that was to be included. Since grid connection was mentioned there needs to be some additional control logic — as mentioned by default solar installations have kill switch for blackouts. Something has coordinate use and direction of electricity to/from grid, battery/-iesm generator.
          But article is bit light on details.

        • These questions and assumptions are good ones, though incomplete. We are glad to answer questions directly and provide accurate cost analysis for each specific installation, this includes factoring in SGIP, if applicable. Please call 916-304-1603.

          • I’m thinking you should give a complete, concise list of what is in your package. I’m getting a bad feeling about your business based on the lack of clarity and the “call me” stuff.

            This is not a free advertising site.

            I’m taking down the comment with the phone number. If you want to get back with details, that’s fine. But give information, not a sales pitch.

        • To be fair, full pricing varies by situation. Marketing material will be biased towards the company typically. A few totals from actual customers would be helpful “check out what we did for bill. He paid $XYZ and we put in bla bla bla. On top of that, he received $ABC in rebates for a total cost of ….”

      • Yes! Thank you, Kyle. The renewable energy source, whether PV, generator or wind—is a separate system and not accounted for in these notes.

    • Thanks for commenting. Please follow the comment thread to see the details provided.

  • Please see the response to all questions below. Thanks for your input and feedback!

  • Thanks for the details! What is the expected lifespan of LiFePO4 batteries? Do they come with a warranty?

    • The lifespan of LiFePO4 varies according to depth and frequency of discharge. For SGIP, Energizr is sold with a 10 year warranty on both the batteries and the Energizr itself. A rough estimate of battery life based on Energizr use as a back-up system would be 20+ years. For those outside of SGIP, an optional 10 year battery warranty is currently available for $1,500. Hope this is helpful.

      • BYD uses LiFePO4 batteries in its e6 EV. Reports are that they are holding up quite well, even when charged almost always with rapid charging.

        Supposed 4,000 cycles,, which in a 200 mile range EV means the battery will outlast the body. And a second body.

        • Impressive. Thanks for the added details.
