Solar Panel Connection & Angle

In this section, you’ll learn how to connect multiple solar panels and adjust their angles for optimal power efficiency. Follow these steps to ensure your system delivers maximum energy output to your unit.

Connecting the Solar Panels in Series Instruction

1. Connect the negative (-) terminal from the first panel to the positive (+) terminal of the second panel.
2. Connect the negative (-) terminal of the second panel to the positive (+) terminal of the third panel.
3. The remaining positive (+) terminal on the first panel and the negative (-) terminal on the third panel will be the main output connections for your charge controller, battery, or inverter.

Series wiring specification

	Panels wired in Series Each panel specs:  150 W   No. of panels:   2   • Use series wiring when Y splitter is not present. • Only use with MPPT (Charge Controller) model number solar controllers: • 12V Solar panel: 75-10, 75-50, 100-20, 100-30 • 24V Solar Panel: 100-20, 100-30 • The sum of all panel's open circuit Voltage should not exceed 100V (see panel sticker for specs)
