PWM-30-UL Installation: Low Voltage Disconnect Function
**This article relates to the USB Port, and Inverter Remote Signal** To prevent the battery against over-discharge this function automatically switches off the USB output port when Battery 1 voltage is lower than 11.0 VDC. If a compatible inverter is connected and set to remote mode, the controller will also switch o…
PWM-30-UL Installation: System Voltage and Current
# System Voltage and Current Specifications The GP-PWM-30-UL is intended for use at 12 VDC system voltage and is rated for a maximum continuous DC input current of 37.5A and input voltage of 35VDC. Per the National Electric Code (NEC) article 690.7 and 690.8, PV module nameplate ratings must be multiplied by requir…
PWM-30-UL Installation: Supported Battery Types
The GP-PWM-30-UL is suitable for use with lead acid batteries (vented, GEL, or AGM type) as well as some lithium iron phosphate (LiFePO4) batteries that are supplied with a Battery Management System (BMS).
PWM-30-UL Installation Introduction
# Installation A Solar Controller (or Charge Controller / Regulator) is an essential component of your photovoltaic solar 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 …
