I have newly installed easyplus and connected a generator 5kva honda+sincro into ac in. 460 Ah flooded batteries. When charge mode on and using ac out0 to use heavy duty equipment like vacuum cleaner 2400w the dc charge and ac out cuts off immediately when switching vacuum cleaner on. 700w coffee maker works fine. What could be the problem. It should bypass 16A? After some tens of seconds the charge and ac out0 is back.
