My current system has been working more or less flawlessly for four years. One Schneider xw+, 2x mppt 60150, 5.7kw panels, 14kw kohler genny that almost never is needed, scp, gateway, and 4x simpliphi 3.5s, voltage controlled for 56V bulk/absorb for 6min and 54V float. Also ags for the kohler.
So I inherited 2x xwpros, with unknown history, but they might be nib. Also, 8x sunpower 6.5kwh units, which is a separate discussion, but long story short, I'm not going to use their bms, and have bought 4x of the newest jk units to trial, and then maybe get four more to complete the utility of these batteries. So, the 2x xwpros were originally meant for replacements for my xw+ if it ever busted, but I chucked both of them in the wall in my garage which is pretty far from the existing electronics room, but does have power from the existing setup. The eventual plan is to make sure I can make the sunpower units work with the aftermarket jk bms, and then add all 8 to the current system, and move the four simpliphis to the garage, with one or both xwpros connected.
Right now I have one xwpro connected to one hacked sunpower battery with a jk bms - no closed loop going at the moment. No mppts or solar at all here - just messing with it with no loads and no charging.
My question is how to, at least temporarily, charge the sunpower/hacked with jk units from my existing power in the garage? My thought is to use the AC2/generator charger and just manually flip a breaker when I know my four simpliphis are charged midday. Or, I could use AC1 and pretend the xw+/simpliphis are grid, and get a little fancier with charging. Or, I could see if I could get the jks to work in closed loop with the schneider pros, and charge off of soc.
I should mention too that I have an insight facility on the isolated xwpro system right now.
Again, I'm imagining getting all the sunpower units working with the isolated xwpro system with no charging capability, and then moving them to the xw+ system, and maybe moving the 4x simpliphis to the garage to work with the xwpro(s). There is the possibility that I could get another mppt60150 and add some panels over in the garage area, as I do have a bunch of panels laying around. Maybe just 9 for one mppt60150, which would be half my current solar supply.
My main question still is how I might connect my current system to charge the isolated system - use AC1grid or AC2 generator? Probably limit it to 10A or so.
