OVERVIEW

MODEL: GP-MPPT-85/20

Use a solar controller to maintain a battery’s life by limiting the current flowing into it once it is fully charged.

IP68 rated waterproof protection with MC4 solar connections and Delphi battery connections
Up to 98% power conversion efficiency
3-stage I/U curve sweep algorithm increases battery lifespan
Anodized aluminum with built-in heat dissipation
Fully encapsulated design prevents damage from water, corrosion, insects and/or dust
Works with 12 or 24V battery systems (automatic battery voltage detection)
Compatible with 60-cell modules
Converts excess array voltage into additional charging current
Allows up to 50% oversized array power for adding additional capacity in low-insolation months
5 year warranty
