I'm fully here in Spain now. Residency all approved. Just waiting for my shipment of household goods to arrive which is somewhere out in the Atlantic now and due in May. The panels are doing a great job now that the crazy cloudy and rainy days have diminished. I'm curious if the system during the summer will handle a couple of room a/c units now. I suspect I'll either need to upgrade or do a grid tie for the additional load. Does anyone know if it's possible to mix lead acid and lithium on the same charging circuit? The battery room has lots of additional room and I could certainly fit a good number of LI batteries into some series/parallel circuit with the lead acid ones and stay at 24V if it is.

Hi AZ , welcome.

I believe it is possible but likely to be definitely not recommended - chances of destroying Li bank not worth it .

Better upgrade to 48v system and go all Li when time comes , or add all new circuit - however I would defer to someone who knows more - likely found on FB or Reddit .
