To connect a solar panel with batteries, first, mount the solar panel in a sunny location and secure it with appropriate hardware. Next, attach the solar panel's positive (+) and negative (-) terminals to the corresponding terminals on a charge controller. Then, connect the charge controller to the battery bank's positive (+) and negative (-) terminals to regulate the charging process and prevent overcharging. If using multiple batteries, connect them in parallel or series for the desired voltage and capacity[link|https://softkeybox.com/|.|new_window=true] Optionally, connect an inverter to the battery bank to convert stored DC energy to AC for powering household appliances. Prioritize safety by using fuses or circuit breakers and monitor the system regularly for optimum performance. Seek professional help if unsure about the setup.
