Solar BMS – Solar Battery Management System
Is a solar charge controller designed to replace the Lead Acid solar charge controllers most people use today in Offgrid, RV, Boats and multiple other applications with 12V and 24V systems.
Solar BMS can be used with 3 up to 8 Lithium cells in series (any type) or even supercapacitors.
Any number of parallel cells are no different from a single larger capacity cell so it will just count as one.
The new SBMS0 plus DSSR20 is replacing all other models and can handle up to 30kW of solar PV using multiple DSSR20.
