1. Introduction The GS-MPPT-320W solar charge controller uses a PWM-based DSP controller to keep the batteries regulated and prevent the batteries from overcharging and discharging. Applying an intelligent MPPT algorithm, it allows the GS-MPPT-320W solar charge controller to extract maximum power from the solar array by finding the maximum power point of the array. The solar charge controller facilitates a standalone energy system.

Wall Terminal Installation Step 1: Prepare flat screwdriver, supplied terminals and stripped wires. Chart 1 Step 2: Insert stripped wire into supplied terminal. Use crimping tool to press stripped wire and terminal into position. Refer to chart2. Fig. 1 Step 3: Screw assembled terminal and wire into solar charge controller. Refer to chart 3. Chart 2 Fig. 2 Wiring CAUTION! Be sure to secure all wiring, especially for mobile applications.

Step 2: Battery Wiring Step 3: Solar Module Wiring WARNING: Risk of electric shock! Exercise caution when handing solar wiring. The solar array high voltage output can cause severe shock or injury. Cover modules from the sun before installing solar panel wiring. Step 1: connect battery positive (+) wire to the positive terminal of the unit and load negative (-) wire to the negative terminal of the unit. Step 2: install a DC Breaker or a DC fuse holder in a positive wire.

Status, LED/LCD Display and Audible Alarms Fig. 9 CAUTION: It will not damage the solar modules or charge controller if the polarity is reversed. However, the unit will not be able to function. WARNING! Please use the appropriate cables. Please refer to Important Safety Warnings Section for cable details. Step 4: Switch on DC breaker or install DC fuse After completing all wire connections, double check to ensure that the wires are connected correctly. Switch on the DC breaker or install the DC fuse.
