HOW TO INSTALL BATTERIES IN SMART PHOTOVOLTAIC COMMUNICATION CABINETS
This guide provides step-by-step instructions on how to install your R-BOX-OC outdoor solar battery cabinet, including site selection, assembly, wiring, and system testing. [pdf]
How you connect solar panels to battery systems depends on your voltage requirements: Series wiring adds voltages while maintaining the same current. Connect the positive terminal of one panel to the negative terminal of the next. This configuration works well for MPPT controllers and higher system voltages.
Connection sequence is critical for equipment safety – Always connect batteries to charge controllers before solar panels. This prevents controller damage and ensures proper system voltage detection, as charge controllers use battery voltage as their reference point.
With careful attention to safety and proper maintenance, your solar panel to battery system will provide reliable, clean energy for decades to come. What happens if I connect solar panels to the charge controller before connecting the battery? How do I know what wire size to use for my solar panel to battery connections?
Connecting the Charge Controller Connect Solar Panel to Controller: Attach the positive wire from the solar panel to the charge controller's positive terminal, and do the same with the negative wire. Secure Connections: Tighten all terminal screws to prevent loose connections that could disrupt the current flow or cause safety issues.
