Growatt 5000es tripping the power when charging battery

[Andy_Knowles]

Hi All,
I've recently been getting issues with my Growatt when charging the battery from the grid.
I had an electrician come and check all the sockets etc.. on the circuit that goes to my Growatt and all is fine.
It was happening instantly, as soon as it starts feeding the battery (this is with the inverter on or off)
The RCD says it's leakage exceeded,
I've now swapped the inverter for a different one of the same model - it worked at first but is now also tripping after adding a few percent to the battery. I'm stuck as to what to do.
Both the RCD in the house trips and the one inn the outbuilding that feeds my garden office - both are new as of a couple of weeks ago. (As I swapped those first)

Any ideas? I'm honestly thinking I'm at the end of Growatts forever

Yeah. I have Growatt 3000TL. Anytime it tries to charge from the grid my breaker trips. Just had my electrician check/double check all the cables and breakers from the meter, and everything looks good. I'm changing my charge source in #14 to SOLAR ONLY and running #01 on SBU. I have a 5KW battery and sun 98% of the time, so hopefully that holds me through the night. Would love to find a solution to this though.
