A vital component to your solar system! This controller maintains the life of your battery, as it prevents overcharging! Once your battery is at 100 percent, the controller prevents overcharging by limiting solar power flow.
Main Features of GP - PWM - 30 Controller modulation (PWM) technology
Go Power! Maximum Power Boost Technology
GP! 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.
