SpecificationsAdvice on safe use1. The controller will be automatically recognized by 12/24/48V. When installing for the first time, make sure the battery has enough voltage so that the controller can recognize the correct battery type.2. Install the controller as close to the battery as possible to avoid voltage drop caused by overly long cables and affect normal voltage judgment.3. The controller is suitable for three types of battery charging: ternary lithium, lithium iron phosphate and lead acid.4. The controller can only use photovoltaic panels as the charging source, please use DC or other power sources as the charging source.5. The controller will heat up when running. Please install the controller on a flat and well-ventilated surface.Characteristics:1. Adopt industrial grade main chip.2. Large screen, LCD display, charge and discharge parameters adjustable.3. Full 3-level PWM charge management.4. Built-in near charge protection, short circuit protection, open circuit protection and reverse polarity protection are all self-recovery and will not damage the controller.5. WIFIAPP can check the working status of the set machine at any time.6. Battery temperature detection function (optional).indicator lightSOLARSolar access: The indicator light is on when it detects that solar energy is connected to charging, and the indicator light is off when there is no solar energy.BATTERYBattery indicator:The indicator is on when the battery is connected, and the indicator lamp flashes at a switching frequency of 0.5 seconds after protecting the load from long-term voltage, and it is on normally when the voltage rises to the recovery value.LOADING/WIFIThe indicator light is on when the load is on, and the indicator light is off when the load is off. After turning on the Wi-Fi, the indicator light flashes 5 times at a frequency of 0.5 seconds, then returns to the charging indicator state for 10 seconds, and then returns to the WIFI indicator stateButton:MENU/Menu button: Tap the button to scroll through the menusUP/Page up: After entering the menu setting, scroll up to set the function parametersDOWN/Page down: Scroll down to set the function parameters after entering the Laid single settingENTER/Confirmation and load switch button: Confirm to enter and exit menu setting items, load switchDelivery content:1X (1 piece) 20A, 40A 60A 12V/24V/48V solar charge controllerA notice: Due to the light and screen difference, the item's color may be slightly different from the pictures.
