I have a 10800W DC, 10000W AC PV system using 2 SMA SB5.0 US inverters and would like to add Battery Back-up operation to my system. I have been looking at sunny Boy Storage and auto switching unit, my goal is to have power for my home during power outage during the day, and 12 to 18 hours critical load for inclement weather and night operation. do you have any recommendations? I put a BYD H in my cart but i'm not sure if that will do the trick.
Your system is quite large. One 2.5 kWh battery won't be enough. A solid backup would be 4-6 battery modules.
Can the lifepo4 be charged with a standard lead battery charger?
It really depends on the particular model. If the manufacturer states compatibility with lithium batteries, then it can.
Do I need a specific charge controller for this battery bank?
No, most charge controllers support all types of batteries. If you would like detailed advice, give us a call (800)557-5686.
The charger is sold separately.
