MPPT-300-14.6 : 300W MPPT Solar Charge Controller for Lithium

The Powerwerx MPPT-150-14.6, DC-to-DC Solar Charger Controller for Bioenno ¹, RELiON ^{4 2}, & other 12V LiFePO4 Batteries. Rated at 300 watts, the MPPT-300-14.6 solar controller is designed for charging drop-in lead-acid replacement Lithium batteries & equivalent LFP batteries. This is a cost-effective controller for smaller single & multiple panel systems.

Input DC range from 20-50 VDC (check your panel's MPP output spec). We recommend series solar module configurations not exceed 46V Voc in ambient temperatures below 10C.
Output is a constant 14.6 VDC. Rated at 24 Amps maximum. Smart charge controller design will automatically adjust charging output as required by batteries, no user adjustment needed.

The Powerwerx MPPT-300-14.6 is a basic MPPT (maximum power point tracking) controller. It converts higher solar panel voltages down to 14.6 VDC while preserving total power output, making it more suitable for charging LifePO4 type batteries in sub-optimal daylight conditions. The solar input is pre-wired with MC4 style connectors.
The output comes pre-wired with the popular Anderson Powerpole 30A connectors.
