    Plugged a 12V DIY battery. Works well. I have no BMS right now. Just watching the voltage. I have not tested with 48V yet as I dismantled the powerwall for individual battery testing. As you can see, it just works. I cannot easily change the battery type sadly.

    Am happy that i did my whole solar setup by myself !! Its a week now , i use old ups battery in 12V system with 650 Watts transformerless inverter and 5 x 100 watts solar panel all connected in series . First impression is good but not up to my expectations. I found that only 280 to 300 Watts ( 22 A ) is going to my battery at peak sunlight , I was expecting 30Amps so I need to do further investigation to find actually which part is performing bad. from this setup am getting 1 to 1.5 KWH daily , my expected power production is 1500 to 2000 Watt Hours.

    I've talked somebody that have the same unit working for some time now, and he told me that I have made a very good buy. On basis of that and my own research, I'm convinced that it is a good buy. I have not tested it as I still need halve the components for the system. Slowly building up to get less dependent on grid power and a big cut on cost, Expenses may be recovered in less than 3 years. From then on it is maintenance cost that should be less than 25% of grid power cost.
