Any suggestions? My Xantrex charger/inverter crapped out and I stupidly bought the next gen version, installed it, & now realize it only inverts! NOT A CHARGER! How did I even pass the bar?

My old Heart Freedom 2000 inverter/charger gave up the ghost last year and I replaced it with Xantrex's XC 2000 inverter/charger. So far I have been very pleased with it, and it is lithium-capable when I take the step from AGM's.

I would check out the min charging amps outlined in your battery specs and start with that.

It depends on how fast you want to fully charge. Some say 10% of bank capacity.

Check with the battery manufacturer for optimal charging currents and voltage.

Most AGMs can accept up to 40% of their ah capacity. The closer you get to 40% the quicker you'll get to the 90% SOC which is good for the battery. But it makes very little difference in the over all elapsed time. See the article below.
