PulseTech SP-50 12V Solar Pulse Charger w/Controller, 50W

The PulseTech™ SP-50 12V Solar Pulse Charger (mfg SKU # 735X350) is used with the 20A solar pulse charge controller to charge, desulfate and protect all 12-volt battery systems. It works with any lead-acid batteries (VRLA, AGM, flooded cell and gel). The solar charger increases the battery's ability to maintain charge and accept re-charge. The charge controller utilizes the advanced pulse width modulated (PWM) technology. It features temperature compensation, pre-programmed multi-staged charging algorithms, 12V/ 24V auto-switching, and battery protection from overvoltage, reverse polarity, plus reverse current from battery to the panel.

The SP-50 12V solar panel (57W, max current 2.87A) measures 21" x 26" x 0.5". The rugged PT20 solar pulse charge controller comes with a temperature sensor (9.5'), fused battery harness (9.8'), solar input adapter, and 3" black thin-wall heat shrink tubing (3/8" diameter).
