30A MPPT Solar Charge Controller, 12V/24V with LCD and USB
Product Overview
This 30A solar charge controller manages a compatible 12V or 24V solar battery system with an LCD and three front-panel buttons. It is the 30A MPPT configuration, with a separate 10A rated load output and two USB ports providing 5V output up to 2A maximum.
The display brings solar, battery and load status together with voltage, current and time information. A five-level battery indicator helps check system status, while the Menu, Up and Down buttons provide access to the adjustable parameters.
Key Features
- Automatic 12V/24V system recognition supports appropriately matched battery systems.
- A 30A charging rating is kept distinct from the 10A load-terminal rating.
- LCD status information helps inspect charging and connected-load behavior.
- Adjustable float, load-disconnect and load-reconnect settings support system setup.
- Dual USB ports provide a convenient 5V output alongside the dedicated battery and load terminals.

Controls & Status
Menu switches between parameter screens and settings. Up increases the selected setting; Down decreases it. A steady charging indicator means charging, while a slow flash indicates float charging. If the load icon flashes slowly, reduce the connected load; a fast flash indicates a short-circuit condition that must be isolated and corrected.
If charging stops in sunlight, check the PV connection and polarity with power safely isolated. An unlit load icon can indicate an unsuitable mode setting or low battery voltage. Use the included manual when interpreting settings.
Compatibility & Notes
Match battery chemistry and every charging setting to the battery manufacturer's requirements; a preset label does not establish compatibility with all lithium batteries. Ensure the battery has sufficient voltage for correct system recognition. Use suitable solar panels as the charging source, not a general DC power supply.
Install near the battery to reduce voltage drop and mount on a flat, ventilated surface. Observe the separate charge, load and USB limits and have electrical wiring completed by a qualified installer. The USB rating is not multiplied by the number of ports.
Package Contents
One 30A controller and one user manual in a product box. Solar panels, battery, wiring and connected loads are not included.
