This is a complex issue and you need to get it installed correctly for your own safety.

I believe a solar inverter or any other microgeneration device needs to be on it's own circuit, not sharing a circuit with any loads.

Not sure that's relevant to boiler but it does indicate that other issues may have been missed in the install.

Hopefully there's an AC isolator between inverter and house wiring. How does the boiler work when that's switched off?

Regarding the boiler itself, does hot water require a permanent live, not needed for heating?
