Model: Sohigh PCB-20A
Brand :Sohigh Solar
Voltage(V): 12/24V
Product Origin: Guangzhou,China
Capacity: 20A
Feature of the PWM solar charger controller
Accurate Monitoring
Adopting an upgraded 32-bit chip, this 30 Amp solar charge controller enhances the data processing ability to trace data faster and monitor data more precisely. The LCD screen and settings button allow you to customize parameters and monitor the PV system in real-time.
Easy To Install And Use
There are polarity (+/-) icons on the charge controller for easy wiring. It comes with 6 spade terminals for safer connectivity without shortening the circuit caused by the bare copper wires contacting other terminals.
Works With Popular Batteries
This solar controller works with LiFePO4, Ternary Lithium, Gel, Flooded, AGM, and Sealed batteries. Supporting 12V (up to 450W) and 24V (up to 900W) PV systems, it can be widely applied on motorhomes, sheds, boats, water pumps, and more.
Intelligent PWM Charging
Supports smart 3-stage charging (Bulk, Float, and Equalization) for Lead Acid Batteries and 2-stage charging (Bulk and Float) for Lithium batteries, which can regulate the flow of electricity to expand the battery’s lifespan. For a dormant lithium battery, this PWM solar controller can send low current to activate it.
7-Point Safety Protection
This PWM controller is equipped with dual MOS circuits to prevent reverse current. It protects against reverse polarity, battery overcharge, battery over-discharge, over-temperature, and short-circuiting. It also provides self-recovery protection for your PV system.
