Description

MAX PV Input 100V, 240W @12Volt; 480W @24Volt

This 20A solar charge controller uses advanced MPPT (Max Power Point Tracking) technology to quickly and accurately track the maximum power point, delivering up to 99% tracking efficiency and 98% peak conversion efficiency. It maximizes the energy harvest from your solar panels—even in cloudy or partially shaded conditions—for faster, more stable charging performance.

The improved 3-stage charging algorithm (Bulk, Absorption, Float) charges your battery as quickly and efficiently as possible while ensuring safe recharging. This optimized charging process helps extend battery lifespan and enhances overall system performance.

Equipped with comprehensive built-in protections—including PV over-voltage, battery over-voltage, over-temperature, over-charging, short-circuit, reverse polarity, and temperature compensation—this controller safeguards your entire system and ensures your battery is safely, efficiently, and fully charged to 100%.

Supports a wide range of 12V 24V batteries, including Deep Cycle Sealed (AGM), Gel, Flooded, Lead-acid, and LiFePO₄ lithium batteries. A truly plug-and-play solar charge controller designed for versatile 12volt and 24Volt solar power systems.

The LED display clearly shows the solar panel’s charging voltage and current, as well as the battery voltage, allowing you to monitor the system’s charging status at a glance. All parameters are easy to read, and operation is simple and user-friendly.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $24 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for SUNER POWER products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
