Out of interest, since you`re talking about 3.5kw output, can you tell
me what protection system you`re using ? (G83/1 applies I think, but i`m
not sure whether you`re looking to interconnect back to the mains
network)

If it is to be 'interconnected back to the mains network' then why not use that as the dump load?

When the batteries are fully charged, and the hot water is fully heated, then the surplus can go
back to the grid?

Can you tell me what sort of system YOU'RE using?
