In the general case, the MPPT function needs to be implemented with a switch mode DC-DC converter to maximize the product (output power) of the output voltage and the charging current.CN3722 adopts the switching step-down mode DC-DC conversion to realize the maximum power point tracking function of photovoltaic cells. Its input voltage can reach up to 28V, which is very suitable for applications with large difference between input voltage and battery voltag ## Features - High-end technology MPPT solar maximum power tracking charge management chip, with turbulence, constant current, constant voltage charge management - Adopt imported high frequency low conduction internal resistance double MOS tube, high current diode, high efficiency flat high-power inductor, alloy current detection resistance - Extra-large aluminium heat sink at the bottom to ensure long-term stable operation at high currents - high speed and efficient charging - Dual status indicator, when the battery is not connected, the red light is always on, the red light is on when charging, and the green light is on ## Technical Specifications | Specification | Value | |---------------|-------| | Color | Red | | Item Part Number | BE-002462 | | Primary material | Aluminium | | Capacity | small | | Manufacturer | Bytesware Electronics | ## Product Details - **Colour:** Red - **Brand:** xcluma - **Material:** Aluminium - **Display Type:** LED - **Manufacturer:** Bytesware Electronics ## Images ![xcluma CN3722 3A MPPT Solar Panel Controller 7.4V 8.4V 12V 2S 3S Li-ion Lithium 18V Input - Image 1](https://m.media-amazon.com/images/I/51HZdxG+FpL.jpg) ![xcluma CN3722 3A MPPT Solar Panel Controller 7.4V 8.4V 12V 2S 3S Li-ion Lithium 18V Input - Image 2](https://m.media-amazon.com/images/I/51LrwZRo8GL.jpg) ![xcluma CN3722 3A MPPT Solar Panel Controller 7.4V 8.4V 12V 2S 3S Li-ion Lithium 18V Input - Image 3](https://m.media-amazon.com/images/I/41vNiKRssBL.jpg) ## Frequently Bought Together - xcluma CN3722 3A MPPT Solar Panel Controller 7.4V 8.4V 12V 2S 3S Li-ion Lithium 18V Input - Electronic spices BMS 18650 Lithium Battery Protection Board (3S, 20A, 12.6V) (Pack of 2) - THEMISTO - built with passion 5 mm Shank M10 Arbor Mandrel Cutting Tool Accessories for Angle Grinder Drill and RS775 Motor, Metal, Multicolor --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/400761587-xcluma-cn3722-3a-mppt-solar-panel-controller-7-4v-8](https://www.desertcart.gr/products/400761587-xcluma-cn3722-3a-mppt-solar-panel-controller-7-4v-8) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-04-30*
