The popular solar controllers on the market mainly include ordinary solar controllers, PWM solar controllers and MPPT solar controllers. When choosing a solar controller, you should pay attention to:

1. The maximum power of the controller: It is necessary to pay attention to the maximum power of the controller. For example, the power marked by the Huineng Tracer-7810BP controller is 390W/12V or 780W/24V, then the size of the photovoltaic module cannot exceed 390W under the system voltage of 12V. 24V systems cannot exceed 780W.

2. Controller voltage: It is necessary to pay attention to whether the system voltage supports this gear. The T series only supports 12V/24V. If the customer requires the voltage level to be 48V or the inverter to be 1000W, it is necessary to select the corresponding controller model.

3. Determine the load terminal: When preparing to choose the non-blue series controller, you need to know whether the DC load terminal is required.

4. Communication requirements: Collect whether the customer needs communication requirements, select the type according to the controller specification, and pay attention to whether the controller to be selected has the communication function.

5. Special requirements: Whether the customer needs to have a regular or remote monitoring platform, please pay attention to collecting such information.
