Oh yes. It's always nice to see grid import at such low levels.
Just refining the threshold for iBoost so that it does not empty the battery.

Well... its all gone south.
Was testing the EPS (Emergency Power Source), Heard a big clang from the distribution box (may be a contactor) the inverter went off line and the batteries shut down. On restoring the power, batteries are no longer sensed by the inverter. One of the batteries shuts down after turning it on, the other one just remains on but not sensed by the inverter.

What was connected to the EPS at the time. Were your solar panels live?ispookie666 said:Well... its all gone south.

@QrizB I wish! Ha ha
I think it's Givenergy's wiring diagram and contactors which the installer had done or their own system in the distribution box. It seemed to work ok the other day, when power went off.
@JKenH yes, Enphase system - I presume it would have shut down once the grid went offline. I was actually checking if this was going to happen!
