I have Multiplus 12-800va to power some led lights and wifi router when we have load shedding. The system consist of 1x 120 amp 12v Lifepo4, Multiplus 12-800va, smart shunt, battery protect going to a bulkhead with plugs and light.
When the Multi is on and plugged into the mains to keep the battery charged and a load is added like a 9 watt led light the Multi goes from green light to amber light and then switch off. After a while it will switch on and repeat the cycle.

What can be the cause of this?
