MODEL: GP-PWM-30-UL

A solar charge controller is an essential component of your photovoltaic (PV) system. The controller maintains the life of the battery by protecting it from overcharging. When your battery has reached a 100% state of charge, the controller prevents overcharging by limiting the current flowing into the batteries from your solar array.

This unit is slightly used with no problems. Guaranteed working as shown in photos. Sells new for $275, you can get it for 50% off.

Features:

• Dual Bank capable
• Bluetooth ready; used the Go Power! Connect app (Click here for more info)
• 12 volt flush mounted PV charge controller rated for a continuous solar current input of 30 amps and 600 watts.
• Uses pulse width modulation (PWM) technology
• Unique four stage charging system for Lead Acid and Lithium Ion batteries with optional equalize setting, to charge and protect your battery bank
• LCD digital display that shows solar array charge current, system battery voltage and battery capacity
• Built-in USB charge port
• Connects up to 600 watts of solar
• Charges 1 or 2 battery banks
• Remote on/off control of select Go Power! ISW inverters
• 5 year warranty

Capabilities

Using Go Power! Connect, you can connect to your PWM-30-UL controller to:

• Set the battery type and charging profile
• Turn your compatible Go Power! ISW Inverter on or off
• Toggle Maximum Power Boost mode
• View essential battery stats, including:
• Battery Voltage
• PV Charging Current
• Battery State of Charge (SOC)

Maximum Power Boost Technology

Our 30 Amp Digital Solar Controller features Maximum Power Boost Technology (MPBT). This allows you to override the normal charging algorithm of the solar controller to 'boost' the solar charge, which is ideal at the end of the daylight to ensure batteries are topped up for the evening. Performance of the solar controller will not be affected if MPBT function is not utilized.
