Advanced Pulse Technology: Comes with the PT20 Solar Charge Controller, which uses advanced pulse width modulated (PWM) technology. Also features temperature compensation and pre-programmed multi-staged charging algorithms, as well as battery protection from overvoltage, reverse polarity, and reverse current from battery to solar panel.

Multi-Use Durability: This solar charger is used to charge, maintain, and desulfate any individual 12V lead-acid batteries (VRLA, AGM, gel, and flooded cell), as well as two to four 12V batteries connected in parallel, making it ideal for heavy-duty applications. The plastic coated panel (18.69" x 16.13" x 0.2") is virtually indestructible and impervious to weather and age. It has a 15' box-to-panel cable and 10' box-to-lug cable. The rugged "all-weather" PT20 includes a 9.5' temperature sensor, 9.8' fused battery harness and solar input adapter.
