Does PV to battery charging function work while unit is in "search mode" drawing only 15w?



The PV function is not handled by this Quattro inverter, rather it would be handled by the solar controller that operates independently of the inverter entirely. This means that the inverter can be completely powered off or in the power-save mode and solar would still be able to charge the batteries.


Can a single SOK 48V 100Ah battery power this inverter or will i need to create a parallel connection with 2 or more?



One battery is meeting the absolute bare minimum, however, if you use the surge capacity of the inverter, it will likely cause the battery to go into overload.
