Hi there,
I have a new Phoenix 12/1200 inverter powering a 140 watt computer setup through a new Filax 2 transfer switch.
The inverter is connected to the priority source side of the Filax 2 and shore/mains power is connected to the alternative source side.
This works fine but I have noticed some odd quirks of this setup.
-Both power sources need to be connected and ON for the Filax to successfully begin feeeding power from the inverter.
-If the whole system is off (mains power disconnected, inverter off), after switching on the inverter, the filax will not allow current to flow from the inverter until the mains is on.
-Leaving the inverter on all the time fixes this issue, but has a 2 amp standby current draw.
-Reversing the setup works fine! Mains to Priority, Inverter to Alternative. Everything works perfectly.
So, i suspect the issue lies with the inverter/filax combintion. Perhaps the filax is too sensitive and detects a voltage/frequency drop of the inverter first startup and cuts out. The inverter runs 16mm2 power cables which are 1m long.
Oddly if i disconnect all loads from the inverter (monitors etc) the filax will successfully start without mains power connected, but after connecting loads carefully, it disconnects. Connecting mains power 'reassures' it that everything is ok and then all is fine and cut-in cut-out works perfectly.
The irony of this fault is after a full power down, you would need to steam back to port to connect to the mains, to reconnect your inverter.
Thoughts?
