GP-PWM-30-UL / PWM Solar Controller / Overview: Supported Battery Types

The GP‑PWM‑30‑UL solar charge controller is designed to work with a wide range of battery technologies, making it a versatile choice for RV, marine, and off‑grid power systems. It is suitable for use with traditional lead‑acid batteries, including vented, GEL, and AGM types, providing safe and efficient charging across these common formats. In addition, the controller is compatible with certain lithium iron phosphate (LiFePO4) batteries, provided they are equipped with an integrated Battery Management System (BMS). This ensures proper regulation of charging and discharging cycles, protecting the battery from over‑voltage, under‑voltage, and other potential issues. By supporting both lead‑acid and lithium options, the GP‑PWM‑30‑UL offers flexibility for users who want to upgrade or mix battery types within their solar setup, while maintaining reliable performance and long‑term durability.
