Hi
I have a Fox battery installed connected to an AC3 inverter and PV panels connected to a TG3 inverter. To shut the system down, I have seen a video somewhere on this forum which says the order is DC inverter by the panels first, then the AC inverter; then the battery (power followed by breaker on the battery). But I have also seen documentation saying the order should be AC first, then DC.
What is the correct order?
thanks
Here is what I was supplied with mine, though they missed the battery part.
Shut-Down Sequence – (Switch OFF)
1. Turn OFF the PV supply at the consumer unit (3).
2. Turn OFF the AC isolator at the consumer unit (3).
3. Switch the AC Isolator at the inverter to OFF (2).
4. Switch the DC Isolators at the Inverter to OFF (2).
5. Battery off
Then I do all of that in reverse.
