The Amptron 12V/24V 20A MPPT Solar Charge Controller with Bluetooth is a multi-peak maximum power point tracking controller with built-in Bluetooth for monitoring and configuration from Android and iOS devices.
It suits LiFePO4, sealed lead acid, gel and AGM batteries. The MPPT algorithm holds output through partial shading and increases charging efficiency by 15 to 20 percent over a PWM controller.
The controller supports temperature compensation and historical data storage, with protection against PV reverse polarity and reverse current. It is negatively grounded and supports RS485 Modbus for external communications. An optional external LCD monitor is available.
