GP-PWM-25 Digital Regulator
25 Amp Digital Charge Regulator
Provides Superior Battery Protection
A Charge Regulator (also called a charge controller) is an essential component of your photovoltaic (PV) system. The charge 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 panel array.
The GP-PWM-25 is an automatic selecting 12 or 24 volt flush mounted photovoltaic (PV) charge controller rated for a continuous solar current input of 25 amps. The GP-PWM-25 uses pulse width modulation (PWM) 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-25 display has a power saving feature that shuts the display off after 30 minutes of no user activity

* The total rated Maximum Power Current (Imp) of the PV input should not exceed 25 Amps.
* The GP-PWM-25 will limit PV current above 25 Amps.
* Although the GP-PWM-25 will accept PV current greater than 25 Amps
for a short duration, damage may occur if the GP-PWM-25 operates continuously with greater than 25 Amps of PV input.
