[QUOTE="Scott Charles, post: 542870, member: 36460"] Hi Andy I dont know much about the Luxpower inverters but i can give you my opinion on what you propose. im not surprised lux say the inverters are not designed for that, probably not completely due to the current limit of 13A but due to the need for neutral earth bonding when switching over to the EPS function. When you are grid connected the neutral-earth bond is upstream but when you lose the grid the EPS output will rely on a secondary neutral earth bond downstream, usually in the EPS CU. You could probably get it to work but without that EPS neutral-earth bond your RCD wont protect you from electric shock under certain fault conditions. A neutral-earth bond is needed for the protection to trigger correctly. [/QUOTE]
