PulseTech PT20 20 Amp Solar Pulse Charge Controller

The PulseTech™ PT20 Solar Charge Controller (mfg SKU # 746X920), with pulse width modulated (PWM) technology, automatically controls solar charging power and protects AGM, Gel, Wet and Lithium batteries. It features 12V and 24V auto-switching and advanced pre-programmed multi-staged charging algorithms. The battery charge controller works with solar panels up to 400W (12V) and 800W (24V). It protects your batteries from overvoltage, reverse polarity and reverse current from battery to solar panel. Overcurrent protection is set at 22-Amps. The patented Pulse Technology ensures an effective desulfation to extend the life of batteries. The temperature sensor is used only with lead-acid/AGM batteries for optimal charging and safe temperature compensation. The adapter allows bare wire connection to solar input.

The rugged "all-weather" PT20 comes with a temperature sensor (2.9m), fused battery harness (3m) and solar input adapter.
