This MPPT solar charger provides you with the ability to get the most possible power out of your solar panel or other photovoltaic device and into a rechargeable LiPo battery. Set-up is easy as well, just plug your solar panel into one side of the solar charger and your battery into the other and you are good to start charging! Solar maximum power point tracking (MPPT) is to ensure that the light intensity change, photovoltaic cells output maximum power, to make full use of solar energy. In general, need to use a switch-mode DC-DC converter to realize the MPPT function, keep the output voltage, and charging current product maximize (output). The output of the Solar Charger is intended to charge a single polymer lithium-ion cell. The load should be connected in parallel with the battery. Each Solar Charger comes equipped with a CN3791 power tracking battery charging circuit and pre-installed four 2-pin JST/PH2.0 connectors. Package Includes 1 x CN3791 12V MPPT Solar Charger Module 1 x Pair of wires with 2-pin JST connector on both sides; Specifications Review: Charge control charge control - Controller is not good, quality don’t buy ## Features - CN3791 12V MPPT Solar Charger Module is a maximum power point tracking (MPPT) solar charger for single-cell LiPo batteries. - This MPPT solar charger provides you with the ability to get the most possible power out of your solar panel or other photovoltaic device and into a rechargeable LiPo battery - Set-up is easy as well, just plug your solar panel into one side of the solar charger and your battery into the other and you are good to start charging! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09NJLP3TM | | Best Sellers Rank | #95,025 in Garden & Outdoors ( See Top 100 in Garden & Outdoors ) #738 in Solar & Wind Power Parts & Accessories | | Brand | TECHTONICS | | Brand Name | TECHTONICS | | Connector Type | JST | | Country of Publication | China | | Customer Reviews | 2.9 out of 5 stars 2 Reviews | | Efficiency | High Efficiency | | Manufacturer | Imported | | Manufacturer Part Number | TECH1615-000 | | Material | Polycrystalline Silicon | | Material Type | Polycrystalline Silicon | | Model Number | CN3791 | ## Product Details - **Brand:** TECHTONICS - **Material:** Polycrystalline Silicon - **Efficiency:** High Efficiency - **Connector Type:** JST ## Images ![CN3791 12V MPPT Solar Charger Module - Image 1](https://m.media-amazon.com/images/I/417x8hzHNnL.jpg) ![CN3791 12V MPPT Solar Charger Module - Image 2](https://m.media-amazon.com/images/I/415N3kj4aqL.jpg) ![CN3791 12V MPPT Solar Charger Module - Image 3](https://m.media-amazon.com/images/I/31v42krrmSL.jpg) ## Customer Reviews ### ⭐ Charge control charge control *by S***M on 23 April 2024* Controller is not good, quality don’t buy --- ## 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.co.za/products/395242075-cn3791-12v-mppt-solar-charger-module](https://www.desertcart.co.za/products/395242075-cn3791-12v-mppt-solar-charger-module) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-05-06*
