Note: User Manual is available for Download in this Page

1. Get the tools and cables ready. Select the appropriate cable to ensure that the current density is less than <6A/mm, which is conducive to reduce the cable voltage damage.

2. This controller will be heated when working. Please install the controller on the flat, well-ventilated environment.

3. In the process of connecting wires, please connect the battery first (in order to ensure the correct identification of the battery voltage level), then connect the solar panel. After the controller completes the battery voltage lever identification, manually close the load output of the controller and connect the controller finally.

4. In order to use security, please do not use solar panels that exceed the rated current of the solar controller; please do not connect the load overrated current. please do not use AC/DC switching power supply instead of the solar panel to connect the controller.

Note for Charging Lithium Batteries:

1. When using a lithium battery in the environment below 0° C, lithium batteries should work well at low temperatures.
2. Solar controllers do not have the equalizing function for the lithium battery. So, the lithium battery must build-in voltage equalizing function.
3. Please strictly connect the controller in the right order, otherwise, it may damage the controller.
4. When removing the cables, please in the reverse order.

Frequently asked questions:

Q: how many solar panels can connect to a 40 amp charge controller

A: the Basic formula is watts = battery voltage × amps, so, the minimal solar panels Power is 450W if the battery voltage is 12V

Q: 40 amp mppt solar charge controller how many watts

A: the Basic formula is watts = battery voltage × amps, so, the minimal solar panels Power is 450W if the battery voltage is 12V

Q: 40 amp mppt solar charge controller how much wattage

A: the Basic formula is wattage = battery voltage × amps, so, the minimal solar panels Power is 450W if the battery voltage is 12V
