I noticed that when we are drawing high currents, the CCGX says we’re in passthrough mode. I’ll investigate this, but if anyone here can elighten me…
OK. I’ve read a bit. It looks like I should have PA enabled. Currently when it flicks over to grid (18% battery), the house runs from grid - batteries stay the same. When sun comes up, batteries start charging from solar. If PA not enabled and demand increases, we hit the grid for lots of amps. If I enable PA, this should allow the batteries to assist with the high demand until it drops off, when solar goes back to the charging. This also means that at night time, all the grid does is feed the nocturnal loads. Am I on the right track? So the grid never charges the batteries?
Enabled PA and problem gone away. Just have to keep an eye on battery level (assuming I can trust the BMS for this). It’s rained all day today and the batteries are at 40% and we’re drawing 2k from the grid. I think it’s set to drop the grid at 50.5V, which won’t happen for a while with no sun.
