Hi Guys,
I have a similar issue on RCT Axpert King 5kVA inverters.
I had 1 x RCT Axpert 5kVA - only ran my light & plug circuits on it / never an issue.
Then I installed 3 x RCT Axpert King 5 kVA inverters in parallel and have our whole house on inverter - we only use it as a standby when our mains fail - not on solar at all - since then my lights flicker when any load switches on and off! Driving us mad!
not even the agents can help us!
I was also contemplating installind a small inverter 1kVA or 3kVA just for the light circuits…
I’m going to try joining the Neutrals from the AC supply to inverters and the AC inverter supplies to the DB and also see that the earth wiring is all joined together. Do not think one shoiluld join Neutral to Earth thou… Mains supply from council’s transformer should have the Neutral and earth joined.
I’m also going to check the parameter settings - cannot find anyone to assist me with those…
