SOL-ARK 1st install!

  • 1.  SOL-ARK 1st install!

    Posted 06-17-2022 10:00 AM

    I installed my very first SOL-ARK OFF GRID system over the weekend. A sol-ark 12K.  3 strings of 10 panels and two 10KWh LiFePo4 batteries (owner will expand to 4 total as budget allows). VERY nicely designed system that includes CAN BUS BMS comms to the batteries. Hooked it up, turned it on, programmed a few battery parameters and IT RUNS PERFECTLY!  When battery is charged, it curtails charging and powers the house as needed, up to 9KW continuous. BEAUTIFULLY DESIGNED GRAPHIC PANEL makes even a rookie understand EXACTLY WHAT IS HAPPENING IN THE SYSTEM!  Highly recommend this for OFF GRID or GRID TIED – since it allows prioritizing what goes where and when in simple easy to follow menu screens. KUDOS to Sol Ark!!

    If you don't mind, approx. TOTAL cost per Watt.

    30 Older panels 7500 watts = $3750, racking $1000, 12K Sol-Ark inverter $7000, 3  10KWH ATLAS LiFePo4 batteries $7500 . 

     

    Inverter output is 9000 watts continuous, so lets use that as the divisor to get cost per usable off-grid watt.  3750+ 1000+7000+7500 all / 9000 = $2.14/watt of useable 240VAC.

     

    Keep in mind that this is with 30KWh of storage. Homeowner can add up to 3 more batteries as he sees fit to extend his storage capacity as he adds loads to his home by simply plugging them in parallel.  The batteries include Anderson powerpole connectors on the bottom, and expansion is as simple as "plug and play". CANBUS comms to the inverter make it idiot proof.

     

    No "labor" costs were included, since the homeowner provided the work crew (relatives, dad, wife, friends). If you wanted this done turnkey, I suspect it would be closer to 5 or 6 bucks/watt or more...   DIY saves a lot of money...

    Hi: I took a close look at your price list. A point of note. Do I correctly read that you got 30 KWH's of Li batteries for $7500? That is about the same cost (Almost) that I just paid for my high end lead. In my research of Li battery pricing, well lets just say, it is unheard of. Li in every single case I have dug into, is always AT LEAST twice the cost of lead or MORE. 
    As an example, the SimpliPhi AmpliPHI LFP 3.8kWh 48 VDC battery retail on line is $3000 which would be $30,000 for 38 KWH's. These are often used with Sol-Ark. inverters.
    Now if you said $7500 each for $22,500 tot for 30 KWH, I would have said that would have been a decent or more usual price.
    In short the above example is $789 per KWH, me at $230 per KWH and you at $250 per KWH.
    Now $22,500 for 30 KWH would have been $750 per KWH, a decent price.

    no error. the pricing is legit. Talk to Darrell Rasmussen at AtlasEnergySolutions dot com and see for  yourself.  I pride myself on being a smart shopper.  The next best pricing on LiFePo4 is from YIY in China, but the ocean freight creates a situation where it only makes sense if you're buying 4 or more.  I have 4 of the YIY 10KW packs on my home off grid system.

    Hi Joe: I contacted your source and person. I posed a specific question to him regarding expected design life in a float application vs the more normal daily use duty cycles and DOD. His response I found misaligned with the questions. I contacted him as a possible "backup direction" to the lead acid solution that I still don't have "in my hands" due to availability delays. I have gotten 2 short I-phone responses from him, neither answered the question I asked. I am responding to him one more time for engineered float life in years. I proposed a 40KWH solution. There best data on their site is a general 6000 cycle life number under unknown DOD. The company I referenced in my initial cost comparison comment has their normal use as 10,000 cycles at 80% DOD. 
    If interested, I will keep you updated on his final response if it comes.
