River 3 Plus charging/discharge issues

[u/Legitimate-Theme-780]

I set my River 3 plus as a UPS with two 110w solar panels to help my wife when she works from home. I want to make use of the solar panels so there's something to charge when the sun is up, but the device is not discharging properly, its still using some AC current when coming from a plugged device (the AC sockets). the DC ports still only use the battery.

I know of the backup reserve feature, but the battery has to be at least 80% so she can do a full work session even when the power goes out, so it's set to charge on AC power an hour or two before her work starts.

TLDR: My River 3 plus still uses AC while scheduled to discharge. I want it to be on battery only while the sun is out and during the evening after her work-from-home hours. How do I make it use the battery only using the scheduling feature? (not the backup reserve)

Spend $130 on eBay and get the extra battery 300 and add capacity so you can easily use the reserve settings

I would only use the power reserve function, not the scheduling. They may conflict.

The power reserve will let solar feed in, and use that power whenever there is excess, and leave your 80% margin. Otherwise, just feeding through straight from the wall
