As you have 1x dedicated 'shoreline' socket - maybe the rest are only powered via the inverter. Correct, at least I believe so.
Is the Inverter switched on ? Yes
Are the inverter 'status lights' working ? Yes, all normal.
Is the inverter supply working (fuse OK) ? Supply to the inverter is fine
Does the inverter have 12v DC input ? Yes
Does the inverter have 230 AC output ? How do I check this?
Have you checked the 230v feed itno the distribution (fuse) box ? Trying to work out where to do so.
Aplogies, I lost electrical power, having reset main rcb to Sterling I got everything back except the 240v as described.
