Mac,
Only removing 6kWh from 46kWh of storage should not be able to produce the
voltage sag to trigger AGS. That’s only about 13% at

Hi Mac
I don’t know if this is pertinent, but it could be the SOC /fndc getting out of
calibration.
I’ve seen this happen if % SOC charge termination is on ( default).
Kinda goes into a negative loop.
The other thought is that 2 hr absorb is pretty short for that size bank, but
maybe that
Mac,
Only removing 6kWh from 46kWh of storage should not be able to produce the
voltage sag to trigger AGS. That’s only about 13% at a 100Hr rate. Voltage
should be no where near that point. Have you verified actual voltage when the
AGS is triggered? Loose wiring or terminal corrosion can

Hello Wrenches,
We recently inherited an Outback system that I've been keeping an eye on via
Optics. Its a dual stack 3648 VFXR, with about 4kW of PV with a single string
Good question. Voltage slowly drops in a fairly linear fashion through out
the night. If it is a sudden short duration load, it is short enough that
Optics can't pick it up, or it get's averaged out. When I've been on site,
I didn't observe any loads that caused concern.

Using Optics, can you equate the voltage sag/ gen start command with a
particular load? Or is the voltage dropping quite evenly over the course
of the night? They could actually be degraded if there is no indication of
a sudden load/ voltage drop. A simple load test when on site can also help
Hello Wrenches,
We recently inherited an Outback system that I've been keeping an eye on
via Optics. Its a dual stack 3648 VFXR, with about 4kW of PV with a single
string of EnergyCell 1100RE battery bank (reported to be ~6 months old)
~.46 kWh at C20.
I have been observing how the system
