Specifications: Efficient chargingEnsure efficient charging of your solar panel with this versatile solar charge controller. Multiple amp optionsChoose from a range of amperage options to meet your specific power needs. Convenient USB chargingDual USB ports allow for easy and convenient charging of your devices. LCD display for easy monitoringMonitor the charging status and voltage levels on the LCD display for improved control. Compatible with 12V/24V systemsThis solar charge controller is compatible with both 12V and 24V power systems. Package Included: 1X Solar Panels Battery Charge Controller 1X User Manual Notes: 1. The charge regulator is suitable for lead-acid batteries: OPEN, AGM, GEL, nickel hydride, lithium, Liions, or other batteries. 2. This controller can only use photovoltaic panels as charging power. Do not use DC or other power as charging power. 3.The LCD display has an error of 0.2 V- 0.3 V, but this is normal 4. Old batteries may be degraded the capacity after hundereds of cycles, easily drop lower than 8V, which results in the controller will be shut off (LCD screen become totally DEAD).
