Solar Charge Controller 30A, 12V/24V Intelligent Battery Regulator for Lead Acid & Lithium Battery with LCD Display and 3A USB Port (0.78kW)

The 30A Solar Charge Controller is an intelligent and efficient power management solution for off-grid solar systems. Designed to handle both 12V and 24V systems, this smart controller automatically detects the battery voltage and adjusts its charging parameters accordingly. Compatible with Lead Acid (Sealed, GEL, Flooded) and Lithium batteries, it delivers reliable power control for solar panel and battery operations.

With a maximum charge/discharge current of 30A, and a power output capacity of 0.78kW, it's ideal for medium-scale solar setups, including home systems, mobile solar arrays, RVs, cabins, and backup power stations. The integrated LCD display allows users to monitor real-time voltage, current, and charging status. Additionally, a 3A USB port is included to power or charge smartphones, tablets, and other USB devices directly.

The controller incorporates multi-layered safety protections — including over-discharge, overcharge, short circuit, and reverse polarity protection. It features auto shut-off below 8V to protect battery life and resumes operation once a safe voltage level is restored.

Simple to install and easy to operate, this solar charge controller is a robust, cost-effective component for any solar energy system.

Installation Instructions:

Wiring Steps:

1. Loosen the terminal screw by turning it counter-clockwise until the clamp plate moves down.

2. Insert the wire between the plate and the top of the terminal hole (not underneath).

3. Tighten the screw clockwise to clamp and secure the wire in place.

Connection Order:

1. Battery → Connect the battery first.

2. Load → Then connect your DC appliances/load.

3. PV Array → Finally connect the solar panel.

4. Disconnection: Reverse the above order.

Usage Notes:

• Always install in a cool and ventilated area to allow proper heat dissipation.

• Not compatible with NiMH, NiCd, or any other unsupported battery types.

• Ensure the battery has sufficient voltage before initial setup (>9V).

• Do not install in direct sunlight or enclosed spaces with poor airflow.

Package Includes:

• 1 x 30A Solar Charge Controller (12V/24V Auto)
