100 W
My current home solar charging setup involves 2 100W solar panels in series fed to a MPT-7210A charge controller which charges a 2 kWh 14S 18650 pack (with BMS) during the day. My bike also uses 14S packs, but I use new high power cells on the bike, and salvaged laptop cells for the solar bank (so no battery swapping). When I pull into my garage after commuting, I charge my bike from a cycle satiator connected to the solar bank through a 120V AC inverter. I'd like to eliminate the inefficiency of intermediate DC-AC-DC conversion, but to charge from one battery to the other I believe I would need a 58.8V capable DC-DC buck/boost supply. This is because initially the voltage of the solar bank will be higher than the bike pack, but over the course of a charge, this will reverse.
Can anyone recommend a DC-DC buck/boost converter for this application? Low power (50-100W) is okay since I'll be charging overnight.
TIA
