Q: Is it possible to reset this unit? It seems to be stuck on Calcium battery, while mine are LiFePo4, and the battery selection button doesn't work.

Yes. This is exactly what happened to my unit. I’ve tested it switching between my AGM and Lithium pressing the button once at a time and waiting for results. It was all the same. The load control light was on all the time whether it was or was not connected to load. Other than that it charged both batteries fine for about three weeks. Then it started to cut the charging out for a few seconds every minute or so and that’s when I decided to return the item. Two stars at best!

Q: Can this handle a 100w solar panel? I’m looking to pair it with a 100w Thunderbolt Solar Panel from Harbor Freight.

Should be fine. The specs indicate a maximum of 500w of PV input. Your 100w panel will prob only push 85-90w on its best day.
