15A 550W MPPT Solar Controller Booster 12V~50V Input Booster24~88V Solar Charger

This controller is a boost controller. The solar panel voltage must be lower than the battery voltage to boost battery charging. For example, when charging a 24V battery, the solar panel voltage must be lower than the battery voltage. You can connect a 12V or 18V solar panel.

note:

Recognizing the importance of energy and safety in product use, we recommend that you follow the following safety recommendations:

1. The battery pack stores a lot of energy, please make sure there is no short circuit inside the battery pack, and it is recommended to install a suitable slow-blow fuse in the circuit to for ensure safe use of the rated current.

2. The battery pack will release flammable gas. Please place the battery pack in a well-ventilated area away from open flames. Avoid short-circuiting cables and terminals, as some terminals or cables can generate voltage and current twice the rated voltage and current of the battery pack. Always use insulated tools when operating.

3. Keep children away from the battery pack and controller to for ensure their safety.

4. Follow the safety recommendations of the battery pack manufacturer to for ensure the correct use of the product.

5. When installing this controller, please avoid mounting it directly on a metal bracket to minimize potential electromagnetic interference.

System operation

1. After the system is connected normally, if there is sunlight, the system starts, the for OLED screen lights up at startup, and the system starts.

2. After the system starts, the for OLED screen will light up, showing the voltage, current, power, power generation of the photovoltaic panel, and the working voltage, current, and temperature of the battery. When the charging current shows 0.0A, it means that the charging is complete and the charging is stopped. Note: Do not use it the working range. On cloudy days, parking lots, and at night, when the photovoltaic panel current is weak or there is no current, the screen will flash or turn off the screen to save power.

3. When the system is running abnormally, press and release the "Reset" button, and the system will automatically restart and restart.

Set the charging voltage of the battery pack

1. After the controller is connected to the photovoltaic panel, press and hold the plus and minus keys at the same time to display the voltage setting screen, and then set the corresponding charging voltage through the plus and minus keys.

Battery pack charging voltage description

12V, 14.4V single string lead-acid battery charging voltage

Single string lithium battery charging voltage 3.7V, 4.2V

Single string iron lithium battery charging voltage 3.65V

Battery pack maximum charging voltage = single string charging voltage * number of battery strings

Usage suggestions

1. Do not overload the controller. The maximum power of the 18V photovoltaic panel in the system is 300W. If there are two 18V photovoltaic panels, please use them in series or in parallel; the maximum power of the 36V system photovoltaic panel is 550W. If there are 2 or more panels, please use them in parallel. If the power exceeds the limit, please use them in parallel. Note: (Photovoltaic panel parameters: working voltage 18V, open circuit voltage 22V; working voltage 36V, open circuit voltage 44V; please read the parameters on the back of the photovoltaic panel before wiring.)

2. The controller will heat up during use. It is recommended to install it in a ventilated and heat-dissipating environment.

3. When the system is in use, it is recommended to connect a switch in series between the battery pack and the controller, and between the solar panel and the controller; otherwise sparks will be generated during wiring; at the same time, connecting the switch also ensures the safety of the system.
