Using 2 to power my house

I would prefer a third, but these two do everything I want. Only about 20 cycles in, but going strong. Easy to install and the bms is all internal and very simple. It does require attention, as they don't drain equally.

Perfect!

Shopsolarkits set me up with a customized WHK3. We doubled the panels, doubled the inverters and doubled the batteries! The only parts I’m waiting on is stuff I didn’t purchase thru SSK! Love the fast response time to questions after the sale.

Great for tiny house

Great for our tiny house! We have had two 5.3 kw Big battery packs powering our tiny house trailer for about six months. We have a gas hot water heater and stove so so our main power draws besides miscellaneous items plugged in are the Apartment sized fridge, a chest freezer, tv, and air conditioning. We weren’t sure if we would be able to run the AC but as long as we turn it off with still about two hours of daylight on our panels are batteries end fully charged. It has been a hot summer with days around 95 to 105° so this has been a welcome surprise. If we have used our batteries too low for the night, a quick half hour running of the generator tops them off. They were easy to install and are neat and compact.
