I suggest that customers, whether they install mppt solar controller, solar system controller or solar RV controller, need to carefully read the following solar controller manuals. There is a special attention to installation precautions. Some unnecessary product failures can be avoided. Let me remind you a few points:

1. The wiring sequence of the mppt solar controller: first connect the battery, then the solar panel, and finally the load. Note: You must strictly follow the prescribed wiring sequence, because some controllers may not automatically recognize the 12V/24V/48V system because the sequence is disordered, which will cause the controller to fail to work normally.
2. It is best to connect a fuse in series with the positive electrode of the battery to ensure that the battery will not be short-circuited, otherwise it will cause serious consequences. The size of the fuse must be 2 to 3 times the rated current.
3. The mppt solar controller should be installed in a dry environment. Even a fully waterproof controller should not be buried in the soil.
