Feature: 1. High Performance: Using industrial grade main control chip, high quality components to improve system performance, the highest conversion efficiency is up to 98%, ultra fast tracking speed to ensure tracking efficiency. The controller is 12V/24V automatic identification, compatible with 12V 24V system.2. LCD Display: The controller has a large LCD display, and the charging and discharging parameters are adjustable. With power off memory function, the status and data can be clearly displayed, and the mode and parameter configuration can be easily switched. It is suitable for home, industry, and business. 3. Multiple Protection Functions: The controller's complete 3 stage charging management improves system efficiency and extends battery life. Built in multiple protection functions, over current, short circuit protection, open circuit protection, reverse connection protection, all of which are self recovery and do not damage the controller. 4. Input and Output: The controller has dual USB outputs, the maximum current is up to 25A, supports mobile phone charging, and uses dual for MOS anti backflow circuits with ultra low heat. The controller will heat up during operation, please pay attention to install the charge controller in a flat, well ventilated place. 5. Easy to Install and Operate: The charge controller should be connected to the battery first, then the solar panel, and finally the load! The disassembly sequence is opposite to the wiring sequence. Specification: Item Type: Solar Charge Controller Package List: 1 x Controller 1 x Manual Note: 1. This controller is 12V/24V automatic identification. When installing for the first time, please make sure that the battery has enough voltage so that the controller can recognize the correct battery type. In order to protect the service life of the battery, once the battery voltage is lower than 8V, the solar controller will automatically shut down. 2. Install the controller as close to the battery as possible to avoid voltage drop caused by excessively long wires and affect normal voltage judgment. 3. This controller is only suitable for various VRLA batteries (including openings, seals, gels, etc.), please do not use it for other batteries (including lithium battery, NI‑MH battery, etc.). 4. This controller can only use photovoltaic panels as the charging source. Do not use DC or other power sources as the charging source. 5. The controller will generate heat when it is running. The operating temperature of the controller is ‑35°C to +60°C. Please be careful to install the controller on a flat, well‑ventilated surface. 6. The LCD display of this controller has an error of 0.2V‑0.3V, but this is normal. |
