Frequently Asked Questions

Q1: When I have some problems in the process of using the
controller, what information can I provide to BougeRV to provide
me with technical support faster and better?
A1: Send the following information to the email: service@bougerv.com,
①The connection method of the solar panels (series/parallel, quantity,
voltage, power). ②The voltage and battery type of the battery. ③The
display data of the controller: battery voltage, battery charging current,
the output voltage of the solar panel. ④Connection from solar panel to
controller and controller to the solar panel.
If the above information can be provided with pictures or videos,
BougeRV can provide you with technical support faster.
Q2: Why the battery is not charging?
A2: There may be the following reasons: the solar panel cable is
connected reversely, the output voltage of the solar panel is lower than
the battery voltage, and the output voltage of the solar panel is greater
than the maximum PV input voltage. ①Check if the cable from the PV
terminal to the controller is correct. ②Check the output voltage of the
solar panel. If the output voltage of the solar panel is lower than the
battery voltage, you need to connect the solar panels in series to
increase the voltage; if the output voltage of the solar panel is higher
than 55 Voc, you need to reduce the output of the solar panel.
