Users must adjust the parameters accordingly based on the actual battery voltage. Features built-in Bluetooth functionality,allowing settings to be adjusted at any time via a mobile phone. - Multi-layered protection: Features a high-quality aluminium heat sink, air cooling and high-temperature derating. Equipped with comprehensive charging and discharging protection mechanisms against overvoltage, overcurrent, overload, overtemperature and short circuits. Ensures reliable and efficient operation in a wide range of operating environments. Comes with a detailed product manual to guide the operating procedures. - Suitable applications: Suitable for small-scale outdoor systems, not large-scale energy storage systems. Examples include outdoor motorhomes and campervans, surveillance in remote locations, sailing boats, yachts and outdoor workstations. In all these scenarios, the controller must be installed indoors to ensure that components are not exposed and to prevent water from entering the controller. - Important notes: Please install the controller in a well-ventilated area, as the heat sinks will become very hot during operation. We recommend fitting a suitable fuse or circuit breaker on the external circuit of the controller. Before connecting or adjusting the controller’s wiring, ensure that the photovoltaic array is disconnected and that the fuse or circuit breaker near the battery terminals is switched off. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0GHRLSH35 | | Brand Name | FUNFAN | | Display Type | LCD | | Item Weight | 1 Pounds | | Manufacturer | FUNFAN | | Material Type | Metal | | Operating Temperature | 45 Degrees Celsius | ## Product Details - **Brand:** FUNFAN - **Display Type:** LCD - **Item Weight:** 1 Pounds - **Material:** Metal - **Operating Temperature:** 45 Degrees Celsius ## Images ![- Solar Charge Controller 12v, 20A MPPT Charge Controller with Bluetooth, Solar Panels Controllers for Lead-Acid Battery, Adjustable OLED Display - Image 1](https://m.media-amazon.com/images/I/61wP2aiwIfL.jpg) ## Available Options This product comes in different **Style** options. --- ## 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/814389987-solar-charge-controller-12v-20a-mppt-charge-controller-with-bluetooth](https://www.desertcart.gr/products/814389987-solar-charge-controller-12v-20a-mppt-charge-controller-with-bluetooth) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-05-27*
