Hello,
Through my misadventures I have come to own several MetaCycle Lithium Ion batteries that I thought would make a pretty sweet little portable solar system. Hacking the charge contactor on the batteries is pretty straight forward, the interface is very simple. These batteries have a pretty capable BMS and I want to leave that intact and actually use it to protect the cells. What I'm looking for is a decent solar charge controller that can be setup to mimic the charger that shipped with the bikes. Same voltage cutouts, high and low. Equipment for a 72VDC nominal battery gets a bit sparse. I'm thinking 2000W of panel configured to match the input voltage of the charge controller, I just need a decent MPPT charge controller that can be setup for true Li Ion cells. Any thoughts? Suggestions?
Once that is solved a decent pure sine inverter would be great as well. Again 72VDC nominal input. 3000W 120VAC continuous would be cool. 2000W would work as well.
