AP series solar charge controller 100A

The principle of MPPT controller: First, the DC voltage and output current of the main circuit are detected, and then the output power of the solar array is calculated, and finally the tracking of the maximum power point is realized.

The solar controller adopts high-speed CPU microprocessor and high-precision A/D analog-to-digital converter. It is a microcomputer data acquisition and monitoring control system. It can not only quickly collect the current working status of the photovoltaic system in real time, obtain the working information of the PV station at any time, but also accumulate the historical data of the PV station in detail. sufficient basis.

In addition, the solar controller also has the function of serial communication data transmission, which can perform centralized management and remote control of multiple photovoltaic system substations.

Effect

1. Power adjustment function.

2. Communication function, simple instruction function and protocol communication function.

3. Perfect protection functions: electrical protection, reverse polarity protection, short circuit protection, overcurrent protection.

The inverter with MPPT maximum power tracking is to make full use of the solar cell to make it run at the maximum power point. When the environment changes, the output power of the solar cell changes, and the output power of the inverter also changes. With an independent load, if the output power of the inverter cannot provide the load power, the load cannot use electricity normally.
