I use it with 10 solar panels (540w each) connected to my hybrid inverter. On a sunny day by 11:00 o'clock my battery is fully charged (200A/h capacity at 48V) After that in summer I also run my 2 aircon from the solar panels. Max charge my panels can give is 70A. Battery unit is rated for max charge 100A.... and 100A max discharge current. My first unit had a faulty battery, but it was exchanged under warranty. I connected it without any BMS communications (was not marked compatible by my inverter manufacturer and they assured me I can run it like that seeing that the battery unit has its own BMS) The internal BMS does the job. Overnight I run 1 fridge + 1 chest freezer + 1 Freezer fridge combo + two 55 inch TV's (2 houses) and the led lights for both houses till bed time 23:30, +1PC + Kettle for tea now and then + 2-3 fans...In the morning I still have between 10-30% capacity left. I am 99% self sufficient. On very cloudy days I use the grid. Where I live...As south as you can get in Greece...we have 95% sunny days. Been running it now for 7 months 1 cycle per day working as it should. Sturdy construction and the best value for money at 10Kw!
