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.

With SolArc 12k

It works well with the SolArk 12k, but we discovered two items to note:

The documentation shows 58 V maximum charge

We found 56V Maximum and 55.8V Float is the correct setting for the inverter or it will cause errors

The BMS doesn’t talk to inverters, so they must be “open loop” and learn over 3/5 charge cycles

It seems to be a good value for the price point, and our home with Air Conditioning works well overnight 😊🙏

It's called BigBattery for a reason

These are large, heavy LiFePo4 Batteries. I purchased four. They arrived well secured on a pallet. The freight carrier was unable to come up my driveway, so he unloaded them at the roadside. I was able to move each battery off the pallet and transport them individually with a dolly without much difficulty. Upon opening boxes, see pics, I was impressed with how well they are packaged. I have not tested or installed them as yet, but if they meet specs, they appear to be a well-built battery and should perform very well for the long haul. Thank you Shop Solar Kits!
