The Bulk setting is 55.2V, the battery voltage is around 53.
Generator quality is good, tried with two different generators, same
result. These batteries can soak up current without the voltage
changing much, great charge acceptance. The BMS is reporting ~40%
SOC. The Outbacks just stay in "pass through" mode as though they
think the batteries don't need it. They don't respond when I tell them
to bulk charge.

It almost sounds like the inverters are not happy with the quality
of the generator output.

*Subject:*[RE-wrenches] Pass-through state Dual FXR system
Hi Wrenches,
I've got an issue that I'm remotely trying to troubleshoot but I
must be missing something.
Specs:
Off-grid
Dual Outback FXR 3648s recently installed
FM100, with about 4k of solar
2 x 16 kWh Blue Ion Batteries, installed this past week
Kohler 14 generator
Outback Mate 3s
The issue is that the FXR inverters aren't charging the batteries
when the generator is running, they are just passing the power
through to the loads. I have verified that AC Input is in "Use"
not "Drop" when generator is running, I have disabled all of the
advanced charging (ie Global charge, float coordination,
auto-charge termination and auto grid-tie control) . I have told
it to "start bulk" both remotely and through the owner on site. I
have done a reboot multiple times of the whole system as well as
the Mate 3s. I even had the owner try a factory reset and
firmware update on the Mate 3s. The firmware was successfully
updated and it appears the factory reset on the mate.
Nothing has changed how it behaves with the generator, generator
just follows the load and no AC charging takes place. Oddly, this
was working fine when we left, we had topped the batteries off
with the generator.
Any ideas what I might be missing?
Thanks for your suggestions
