Maximum power point tracking (MPPT) controller
Rack mount MPPT solar charge controller is an intelligent photovoltaic controller designed specifically for off-grid photovoltaic power generation systems. The product integrates photovoltaic panels, charge controllers, inverters, and battery management systems, and can automatically control the connection and disconnection of solar panels based on battery voltage changes.
Applications
Rack mount MPPT solar charge controller is primarily used in large-scale off-grid solar power station systems, distributed energy systems, remote area power supply, and mobile energy systems such as solar cars.
Features
- Advanced MPPT tracking algorithm allows for a tracking efficiency of no less than 99%
- Rack mount MPPT solar charge controller uses IGBT as an electronic switch, multi-phase synchronous rectification technology to improve equipment stability.
- Advanced PID algorithm ensures a more precise battery energy management system.
- Four-stage charging mode maximizes the utilization of PV modules and batteries.
- Secondary protection function ensures that the battery is not damaged by overcharging in any circumstances
- Dual-loop control of voltage and current allows for setting of current-limiting charging.
- Fully enclosed air duct structure design offers high protection level and high-speed intelligent fan cooling.
- Power generation statistics and real-time power curve functions allows for monitoring the system power generation status at any time.
- Standard Modbus communication protocol based on the RS-485 communication bus.

| Rated voltage | 2V | N | N stands for different rated voltages, the variable for battery charging voltage is based on the value of 2V. For example, if the rated voltage is 360V, the overvoltage disconnect parameter value is 360V/2V*2.65V=477V. |
| Overvoltage disconnect | 2.65V | =2.65*N/2 | |
| Overvoltage reconnect/complete charge | 2.5V | =2.5*N/2 | |
| Equalization charge | 2.4V | =2.4*N/2 | |
| Float charge | 2.3V | =2.3*N/2 | |
| Equalization charge recovery | 2.2V | =2.2*N/2 | |
| Under voltage alarm | 1.75V | =1.75*N/2 | |
| Equalization charge timing | 120 min | ||
| Charge current limiting | ＜ rated current | ||
