HC2420 12V/24V 20A PWM Solar Controller | Electric Car Parts Co

20A PWM Solar Charge Controller – HC2420

Reliable, efficient, and cost-effective solar charge control for 12V and 24V battery systems

The HC2420 20A PWM Solar Charge Controller is a dependable solution for managing small to mid-sized solar power systems. Designed for 12V and 24V battery banks, it utilizes advanced PWM (Pulse Width Modulation) technology to optimize charging performance while protecting your batteries from overcharge, over-discharge, and system faults.

This controller supports a wide range of battery types including sealed, gel, flooded lead-acid, and lithium batteries such as LiFePO4. With built-in RS485 communication (Modbus protocol), it also enables remote monitoring and integration into larger solar systems.

Ideal for RVs, cabins, telecom systems, lighting, and off-grid applications, the HC2420 provides stable performance, smart load control, and long-term reliability in a compact, easy-to-install design.
