hi looking for some advise after installing a multiplus into my total offgrid house, with no generator ( yet) having issue's with earth and neutral relay, my multiplus is before the house switchboard with rccbs fitted, i have tried grounding the ac INPUT as per manual and tried both positions on the number one dip switch open and closed ( position n appendix b).
i have also tried removing the multiplus housing earth also the link pins between earth and neutral buzz bars in the house switchboard but ever time a slight load comes it trips RCCB, the house lights, fridge freezer etc are all fine but as soon as u go to use anything else even a cordless drill charger it trips. also have had new RCCBS fitted and whole house checked by a qualified sparky. who saying it must be issue with inverter and then left after leaving a large bill.
is there any anything else to external to try as losing hair at a great rate !!!!
thanks for your time
