SUNER POWER 30A MPPT Solar Charge Controller for 12V/24V | LCD & Temp Sensor

Overview

Meet the SUNER POWER 30A MPPT Solar Charge Controller, a versatile regulator designed for both 12V and 24V solar arrays. Built to maximize energy harvest from your panels, it combines advanced MPPT tracking with a clear LCD readout and a temperature sensor to support safer, smarter charging in real-world setups such as RVs, cabins, boats, or portable off-grid stations.

With a maximum PV input of 100V and ratings of 360W at 12V and 720W at 24V, the unit accommodates common panel configurations while keeping a compact footprint. The MPPT algorithm quickly and accurately identifies the maximum power point, delivering high tracking efficiency (up to 99%) and peak conversion efficiency (up to 98%) so you can get the most from sunny or partly shaded days.

The controller uses a refined three-stage charging profile—Bulk, Absorption, Float—designed to charge promptly while reducing strain on the battery. This thoughtful charging sequence can help support longer battery life and steadier energy delivery in your system.

Safety is built in. Comprehensive protections cover PV over-voltage, battery over-voltage, over-temperature, over-charging, short-circuit, reverse polarity, and temperature compensation. These safeguards help you operate with confidence across a wide range of environments.

Compatibility is broad. The SUNER POWER regulator supports 12V and 24V batteries including Deep Cycle Sealed (AGM), Gel, Flooded, Lead-acid, and LiFePO4 lithium chemistries. It’s a true plug-and-play solution for flexible solar power setups.

The user experience is simple too. The LED display clearly shows the solar panel’s charging voltage and current, as well as the battery voltage, so you can monitor status at a glance without complex menus. The included temperature sensor provides an extra layer of adaptive charging for temperature variations that affect performance.

Practical benefits in everyday use

In real-life scenarios, this controller shines in off-grid cabins, recreational vehicles, boats, or portable solar arrays. The combination of MPPT efficiency and intelligent charging translates to more reliable energy during long days and in intermittently shaded spaces. The setup is designed to be approachable for both newcomers and experienced installers alike.

• MAX PV Input 100V, 360W at 12V; 720W at 24V, supporting common panel configurations
• MPPT efficiency up to 99% tracking and up to 98% peak conversion for faster charging
• Three-stage charging (Bulk, Absorption, Float) to balance speed and battery health
• Built-in protections including over-voltage, over-temperature, over-charging, short-circuit, reverse polarity
• Broad battery compatibility: Lead-Acid, AGM, Gel, Flooded, LiFePO4, for versatile systems

Installation and ongoing use is straightforward. Place the controller in a ventilated, shaded area, connect per the instructions, and monitor readings on the display. This approach can contribute to a smooth, dependable solar charging experience.

Notes on expectations

While the controller enhances efficiency and safety, results vary with panel quality, shading, and load. Consider it a reliable companion for smarter energy management rather than a guaranteed outcome.
