Features & Benefits

• 【𝐌𝐚𝐱 𝐒𝐨𝐥𝐚𝐫 𝐇𝐚𝐫𝐯𝐞𝐬𝐭 𝐰𝐢𝐭𝐡 𝟗𝟗% 𝐓𝐫𝐚𝐜𝐤𝐢𝐧𝐠 𝐄𝐟𝐟𝐢𝐜𝐢𝐞𝐧𝐜𝐲】 Harness every photon with advanced Maximum Power Point Tracking. Our solar controller continuously scans and locks onto the optimal power point of your solar array, achieving up to 99% tracking and 98% conversion efficiency. This means you squeeze the most energy from your solar panels, charging batteries faster and powering your system longer, even during cloudy or rainy days.
• 【𝐀𝐥𝐥-𝐀𝐫𝐨𝐮𝐧𝐝 𝐏𝐫𝐨𝐭𝐞𝐜𝐭𝐢𝐨𝐧 𝐟𝐨𝐫 𝐓𝐨𝐭𝐚𝐥 𝐏𝐞𝐚𝐜𝐞 𝐨𝐟 𝐌𝐢𝐧𝐝】 Build your solar setup with confidence. This controller safeguards your investment with a full suite of protections: reverse polarity, overcharge, over-discharge, overload, short-circuit, lightning surges, over-power, over-temperature, and reverse current. Our self-diagnostic system proactively prevents costly mistakes and hardware damage, ensuring your batteries and devices stay safe year after year.
• 【𝐔𝐧𝐢𝐯𝐞𝐫𝐬𝐚𝐥 𝐂𝐨𝐦𝐩𝐚𝐭𝐢𝐛𝐢𝐥𝐢𝐭𝐲 & 𝐒𝐦𝐚𝐫𝐭 𝟎𝐕 𝐋𝐢𝐭𝐡𝐢𝐮𝐦 𝐀𝐜𝐭𝐢𝐯𝐚𝐭𝐢𝐨𝐧】 Experience true plug-and-play versatility. solar panel charge controller automatically identifies 12V, 24V systems and is compatible with Lithium, AGM, Gel, and Flooded batteries. Got a deeply drained lithium battery?Our 0V Lithium activation function can potentially recover deeply drained Li-ion batteries, saving you the cost of a costly replacement.
• 【𝐈𝐧𝐭𝐮𝐢𝐭𝐢𝐯𝐞 𝐋𝐂𝐃 𝐰𝐢𝐭𝐡 𝐏𝐫𝐨𝐠𝐫𝐚𝐦𝐦𝐚𝐛𝐥𝐞 𝐓𝐢𝐦𝐞𝐫 𝐂𝐨𝐧𝐭𝐫𝐨𝐥】 The clear LCD display gives you a real-time snapshot of solar input, battery level, and output. Want your lights to turn on at dusk and off at dawn? The programmable timer allows you to automate your system, maximizing convenience and energy savings. Plus, two built-in 5V USB ports let you directly charge phones and tablets effortlessly.
• 【𝐈𝐧𝐭𝐞𝐥𝐥𝐢𝐠𝐞𝐧𝐭 𝐂𝐨𝐨𝐥𝐢𝐧𝐠& 𝐑𝐞𝐥𝐢𝐚𝐛𝐥𝐞 𝐎𝐩𝐞𝐫𝐚𝐭𝐢𝐨𝐧】 High power demands superior cooling. Our charge controllers for solar panels with a robust metal housing combines with smart temperature-controlled fans to dissipate heat effectively under high loads, ensuring long-term reliability. This prevents thermal throttling, maintains peak performance, and significantly extends the lifespan of the unit and your battery through automatic temperature compensation.
