If you have Fluke meter with Fluke Connect (has FC in the model number like
393FC), you can use the Fluke Connect app to data log for a period of time. How
much time varies depending on the tool and test.

My understanding is that if lithium-ion batteries freeze, they're destroyed
with no hope of recovery.
Like Jay said, I'd call the battery manufacturer and ask them. Let us know what
they say.

I've had this issue with a Grundfos circulator pump for my radiant heating. It
works fine when it's on the inverter, but as soon as the generator turns on,
the pump stops circulating. I've got a dual-stack VFX3524, which I'll be
upgrading to Victron shortly.
Thanks,

I've seen this issue with a condo building. A competitor had installed a set of
Outback inverters that wouldn't work because of low AC voltage. They had to
swap them out for an inverter that would work at 208.

I ran into a guy from EG4 at RE+ Texas last week. He confirmed that Outback was
purchased by the parent company of EG4 and Signature Solar.

It depends on how bad the fault is. Insulation resistance testing can
definitely find some intermittent ground faults.

Hello Wrenches,
I installed my off-grid system in 2008. It’s 24 V using 2 V industrial FLA
batteries. As you can imagine after 15 years the capacity of my battery bank is
significantly less than it used to be.
For logistic reasons, I won’t be able to replace them till around June of next
year,
Don,
Your Fluke clamp meter should indicate the current flow by showing a negative
or positive current reading unless you've got an old meter. On the top of the
meter inside the jaw is an arrow that points in the direction of current flow
if the reading is positive. If it's negative, the curren
I worked with a guy who had done installs in Arizona. He had an off-grid
customer spray down their array with cold well water in the middle of the day,
which shattered the module glass.
I’m sure it was an isolated incident, but it happened.
Thanks,

I’d also look at Victron. They can close loop communicate with several battery
systems, and my sources say they’ve also got an EV charger that works with
their off-grid systems that can be programmed to charge the EV when you have
excess solar.

I can't speak to your specific situation, but I live in a strawbale house and
have no problem getting a Wi-Fi signal outside within reasonable distance of
the router.
Thanks,

I’ve run into a similar issue, and the problem was on the utilities side. They
had shut down the local substation for repairs and were pumping power in from
the next town over. To push the power that far, they increased the line
voltage, which was causing issues with the PV inverter.

Ray,
I can’t speak to the Fortress product, but Discover will do what they call
“dynamic charging” in closed-loop installations. Basically, the BMS will tell
the power electronics how to charge the battery, which will lead to a better
charging cycle. For example, if the batteries are discharged
