The application of the solar system controller is very common, in the life, the existence of a larger role, then you know the connection mode of the solar system controller? Here to understand together. Step 1: connect the battery warning: extreme son and connected to the battery positive and negative is the cathode wires on a short circuit will cause the risk of fire or explosion! Please careful operation! Before connecting the battery, ensure the battery voltage is higher than 6 v to start the controller. If the system is 24 v, make sure not less than 18 v battery voltage. System voltage selection only when the first time you start controller automatically identified. Installation of insurance, pay attention to the safety device from the storage battery is the extreme maximum distance of 150 mm, after the connection is verified through insurance. Step 2: connect the load load solar system controller can connect to the rated voltage and rated voltage of the same battery dc power equipment, the controller to the battery voltage to power a load. Pick up the load is negative to the load terminal of the controller. When the load voltage, there may be a connection is earnest, carefully to avoid short circuit. Should the load on the positive or negative wire by one insurance device, the installation process don't get through insurance. After installation confirmed through insurance. If the load is connected via switchboard, every load loop has a separate insurance, all of the load current should not exceed the rated current of the controller. Step 3: connect photovoltaic array warning: electric shock danger! Photovoltaic (pv) array may produce high voltage, be careful to prevent to get an electric shock wiring. Solar system controller can apply 12 v and 24 v type off-grid solar power components, can also use the open circuit voltage does not exceed the prescribed maximum input voltage of grid components. Solar module voltage or lower than the system voltage in the system. Step 4: check connection check again all the connection, look at each terminal is the cathode is correct, six terminals are tight. Step 5: confirm the electricity when the storage battery for solar power supply system controller, the controller starts up, the controller on the battery LED indicator will light, observe whether it is right. Therefore, mastering these solar system controller connection mode is very necessary, each step details are very critical, we need to pay attention to.
