WARNING
Risk of explosive gases: working in the vicinity of a lead-acid battery is dangerous. Explosive gases develop during normal battery operation. Ensure there is enough ventilation to release the gases. Always read this manual and follow the instructions before using or connecting your solar controller.
- Connect the red wire to the positive on the battery and the black wire to the negative.
- Double-check connections. Connecting to the wrong terminals may burn out the controller.
- Ensure power wires are tightened to the correct torque to avoid excessive heating from loose connections.
- Refer to battery specifications and exercise caution to avoid short-circuiting battery connections.
- Accidental 'shorting' of terminals or wiring can result in sparks, personal injury, or fire hazards. Cover the solar panel(s) with a soft cloth to block incoming light during installation to prevent damage if wires are accidentally short-circuited.
- Always install a battery fuse on each circuit, including the solar controller.
