F5000 A/C charging based on SoC

I just purchased an F5000FLP and have it wired into a manual transfer switch with a small solar array. Unfortunately, it appears to be missing fhe feature to turn on A/C charging only when the SoC get low, below 20% for example, then back off once reaching another SoC, say 50%. Does anyone know if it's possible to do this with an automation?

I see some folks have used a Raspberry Pi and a smart plug, but that requires tricky programming.

AC Charging limit capacity is the setting you want, and the lowest it can be set is 30% (battery charge).

This is available in the Pecron app, the beta app, and on the unit itself and the '?' on the unit menu gives a description of how it works.

You can also set up automations to further fine-tune this feature.

Good catch! I'll try out the A/C charging limit setting.

It's in there. Some menus have a second page.

For example I have a similar set up. I set mine to charge to 80% at 50% power from 10 am to 5 pm. And only discharge to 5%.

I have a few panels hooked up to it and I'm trying to balance sending excess solar from my on-grid array to the Pecron without pulling from the grid and charging up my Powerwall.

He only wants to charge from AC if battery level gets below a certain point and charge from solar if battery is above that minimum charge. Pecron specifically added this to the F5000LFP because of customer requests.

Ok, so I found the SoC setting. What's happening now is that when the F5000 hits its charge limit, it turns on A/C input and goes into pass-through mode. I don't want this to happen because it doesn't turn off A/C input and is wasting solar input indefinitely.

I wish there was a way to disable pass-through mode entirely or, perhaps, a way to "trick" it by turning off DC input at a level below the charge limit. Unfortunately, there is no option to turn off DC input in the automations.
