30 Amp PWM Controller (Digital Solar Charge) by Go Power!


30 Amp PWM Solar Charge Controller also known as a Regulator or Digital Regulator 

• For solar system control and protection
• Innovative, compact design
• Can Be Used with GP Solar Kits

Provides Superior Battery Protection!
A Charge Regulator is an essential component of your photovoltaic (PV) system. The Regulator maintains the life of the battery by protecting it from overcharging. When your battery has reached a 100% state of charge, the Regulator prevents overcharging by limiting the current flowing into the batteries from your solar array. The GP-PWM-30 is an automatic selecting 12 volt flush mounted


Photovoltaic (PV) charge controller rated for a continuous solar current input of 30 amps.

The GP-PWM-30 uses pulse width modulation technology and a unique four stage charging system and optional equalize setting to charge and protect your battery bank.

The GP-PWM-25 features an LCD digital display that shows solar array charge current, system battery voltage and battery capacity.

The GP-PWM-30 display has a power saving feature that shuts the display off after 30 minutes of no user activity

Battery Reverse Polarity
Solar Array Reverse Polarity (12V input only)
Over Temperature
PV Short Circuit
Over Current 

The total rated Maximum Power Current (Imp) of the PV input should not exceed 30 Amps. 

The GP-PWM-30 will limit PV current above 30 Amps. Although the GP-PWM-30 will accept PV current greater than 25 Amps for a short duration, damage may occur if the GP-PWM-30 operates continuously with greater than 30 Amps of PV input.
