Hello @Guy Stewart (Victron Community Manager) and @Alexandra,
I would like to know how much DC coupling to apply in an AC off grid system for a well balanced system.
Does the amount of power to be installed on the DC side in an off-grid AC system depend on the capacity of the batteries? If so, what should be the power on the DC side, to avoid the batteries being flat? If there is a generator, is it necessary to add a DC coupling, or would it be interesting to start the generator automatically in case of low batteries?
Thank you
