Thank you for trying to help @timselectric. I've checked today and the mode is SBU. Also likely relevant: in this SBU mode if I only connect either 1 of them while turned off from the button it won't trigger the RCBO. As soon as I connect both in parallel while both turned off they trigger the...

By "since grind can technically be disconnected by opening the input circuit breakers do I need to have another NG bond for the output?" I meant grid not ground, I'm sorry for the typo. There is no circuit breaker for ground. Feel free to have a look at the wiring in the original question. As...

Hello, I've installed 2 x Growatt SPF 5000 ES (I live in Europe) in parallel and a very annoying problem I'm now facing is that they occasionally trigger the upstream RCBO (the residual current component not the over current one) fitted by the utility company. I am confident it's not because...

We also have neutral/ground bond in the utility box where the meter is. Let me clarify what you mean: * disconnect ground wires from both input and output, or just input? * wire together neutral from input and output is that right? Let me voice my worries here: * will this not fry the...

I'm thinking about the N/G bond you've mentioned... If I understand things correctly it means around half of the return current goes through the N and half through G. I've just checked: the RCBO is 300mA rather than 30mA. Standby load for one inverter is around 60W as far as I know which is ~...

As I was changing the leads for the BMS I managed to rip off 2 electrical components and also lost them in the process. Since the BMS was disconnected it's not burnt so I would like to try and solder them back but I don't know what they are. Yes, I know it's dumb... As an excuse the newer...
