A similar question was asked to this previously but never really answered (lots of alternatives suggested but that was it!)
In an off-grid system, can a series of Tesla Powerwalls be AC coupled with a Victron Quattro.
In my specific case I'm running an AC/DC coupled system already with BYD batteries a 10KVA Quatrro, 7kW Fronius and small Victron MPPT.
Rationale: the price of Tesla Powerwalls has now dropped to be cheaper than BYDs - especially if you acknowledge they include an integral DC/AC inverter... I need to double the size of my system in the next 12 months.
Can these systems operate in a sensible fashion together...?
