I have an old Victron Phoenix 24v 3000w Inverter, with an old "generic" solar charge controller.
My old batteries have finally given up.
I want to replace them with something with a good lifespan and was thinking about the Lithium HE battery 24V 200Ah 5kWh
I THINK I need some fancy battery monitor in addition to the battery. Is there something specific I need to check on the old charge controller? (From Memory it had options for sealed, flood, and gel. Lithium didn't really exist when I bought it). If no good what would be a good controller (around 500w of Solar)
Thanks in advance
