2/24 VOLT AUTOMATIC SOLAR CHARGE CONTROLLER P/No.
• • • • • • WARNING Please read these instructions completely prior to installation. Lead acid batteries can be dangerous. Ensure no sparks or flames are present when working near batteries. Eye protection should be used. If mounting on a vehicle follow all manufacturers’ instructions. Given sufficient light solar panels always generate energy even when they are disconnected. Accidental ‘shorting’ of the terminals or wiring can result in sparks causing personal injury or a fire hazard.
Battery Working Voltage Error If battery voltage does not match controller working voltage, controller will stop working. After correcting the voltage, the failure can be eliminated through pushing the load button. Damaged Temperature Sensor If the temperature sensor is short-circuited or damaged, the controller will be charging or discharging at the default temperature 25°C to prevent the battery damaged from overcharging or over discharge.
• Confirm that power connections are tightened to avoid excessive heat caused from loose connection. • Use insulated tools and avoid placing metal objects near the batteries. • Explosive gases may be present during charging. Be certain there is sufficient ventilation to release the gases. • Avoid direct sunlight and do not install in locations where water can enter the controller.
