I am designing a custom solar system setup and want to be sure it will work.
Here's details on all components
Solar Panels - Two 12v panels at 115 W each (already owned)
Charge Controller - Victron BlueSolar MPPT 100/30
Batteries with BMS - Nissan Leaf Generation 2 Battery Module Lithium Ion NMC
2 units at 500 Wh each = 1000Wh x 70% usable = 700Wh usable. These batteries are 60-70% usable capacity (I guess because BMS limits it?)
BMS - https://www.techdirectclub.com/4s-bms-30-amps-assembly-kit-for-2-nissan-leaf-lithium-ion-battery-g1-g2/
Inverter - Victron Phoenix 12V 500W
Wall Charger - 54.6V 9A YALANCHA
My goal is to disconnect the solar panels and connect the wall charger (powered by generator) on cloudy days. The reason I chose a 48v charger is because I will eventually get a 48v battery for an electric bike so I'd need it anyway. I calculate that I can plug this charger into the inverter to charge the bike battery from the Nissan Leaf batteries. What do you think my potential issues are? Thanks a ton!
