How to pair a mppt solar charge controller with a solar panel:
1: The power of the solar panel is firstly proportional to the 12V solar panel. The power of the solar panel is lower than 150W. We use a 10A solar controller for construction, because the maximum charging current of the 150W solar panel is about 8A, and the 10A controller is used. Will suffice. 150W~260W components, 20A controller for construction.
2: The voltage of the solar panel The solar panel has two voltages, one is the working voltage and the other is the short-circuit voltage. For example, a 12V solar panel has a working voltage of 18V and a short-circuit voltage of about 21V. 24V solar panel, the working voltage is 36V, and the short-circuit voltage is about 42V. The 12V solar panel uses a 12V solar charge controller, and how many volts of the solar panel voltage is used. There are also some large voltage 48V, 96V solar controllers.
3: Use occasions The use occasions are generally divided into two types and street lamps. The home use is home off-grid lighting and emergency systems. Choose the right solar system controller. The function of the controller is only for charging and discharging protection of the battery. Street lights refer to solar street lights, and solar street light controllers are used. In addition to the charging and discharging protection function, there are also a variety of working modes.
