Hi everyone, sounds like a great forum, will contribute where I can, but for now I have a few questions for the Deye/Sunsynk people. After some research I came up with a system and dived in. v1.0 installed a few days ago. Unfortunately I have 3 phase to my house, so have one inverter per phase, all sharing one 10kw battery, and so far only solar on 2 of the 3 inverters. 3 x Deye Sun-5k inverters 1 x Freedom Won 10/8 10kw battery 2 x strings of 5 panels each(JA Solar 540W Mono) WI-FI on each working and connected to solarman Entire db board on inverter load except for one main geyser that I put directly on Eskom. Normal stove( need to go to gas still ). Underfloor heating, connected but not touching it for now until I see where I am going with this. So far works great, PV makes about 3500 watts peak.. Initial setup questions How do I get my inverters to upgrade to the latest software? BMS. I have a cable from the battery to inverter no 1. BMS signal is ok on inverter 1 and 3 but not showing on 2? BMS. Do I need a terminator on the Freedom Won battery, at the moment I do not have one? Future? I am running short here and there and needs to balance a bit to make sure I do not exceed the limits, so my question is. Should I not just connect the 3 inverters together on one phase and then I have 15kw? Sort of ignore the other 2 phases or just keep the heating on those.
