I have 8 X 16mm (2 for positive and 2 for negative on each inverter and only 1.5 meters long)
The voltage is fine until I boil the kettle (around 50a) and I get around 4/5v drop across the pack. Probably says more about the batteries. They were sold as deep cycle but have since found there dual purpose so probably not great choice for solar.
I'll see if I can find a serial number online and go direct.coulomb wrote: ↑Sun, 17 Feb 2019, 11:44The control board (plugs into the main board on one side) does contain the main digital signals processor (DSP), which contains the firmware, and a lot of other stuff including the EEPROM where settings are stored, and various op-amps and buffers. I doubt you'll be able to obtain a genuine control board, and even if you could, it might have slightly different pinouts, and might not even fit mechanically.It may have been the control board I read about. Is that the one that holds the firmware CPUs etc?
Might be worth it just for testing purposes etc
Thanks again coulomb
