P.4
ON: Indicates solar panel properly connected and solar power supplied normally.
OFF: No power available or insufficient voltage to active charge controller.
Charging status (“CHARGING” LED - blue; “CHARGE COMPLETE” LED - green)
Normal
Status
Charging LED Charge Complete LED
Conditions
Bulk Charge
ON
OFF
Indicates the battery is charging, virtually all the power
from the solar array pass through to the battery.
Solar power
Weak
Flash
OFF
Indicates the solar panel voltage is too low when it is in
Bulk charge mode. (insufficient daylight)
Float /
Maintenance
Charge
OFF
ON
Indicates fully charge reached, a small “Float” charge
continues to optimize battery when you need
Battery conditions
GOOD LED: ON indicates the battery voltage is over 12.5V, usually indicates when the unit is charging.
FAIR LED:
ON indicates the battery voltage is between 11.5 to 12.5V and needs charging.
LOW LED:
ON indicates the battery voltage is under 11.5V and needs charging.
The LOW LED will be blinking if battery is disconnected from the unit.
If the Solar Panel Power is weak, the charger will turn OFF the charging LED, that indicate the charging status has
been turned off, in order to prevent the current back float to the solar panel. (Back float of current will serious
damage the solar panel.)
2. Digital LCD meter
A digital LCD meter is available on this controller; it will continuously display battery voltage or charging current. You can
select the Current-Volt slide switch at any time on front panel. If the slide switch places at the middle position, the LCD
meter will be OFF.
MAINTENANCE
1. Ensure all wire connections are sound and free from corrosion. Tighten terminal block screws, the array connections and
battery terminals.
2. Visual Check of Solar array and battery output cabling for signs of overheating, damage and cracking.
If you find any wires damage, please replace the new one.
3. Verify each LED status whether it meets the specifications or not.
4. Recommended the above maintenance is carried out at least every 3 months
TROUBLE SHOOTING
1. The system of solar Panels-Controller-batteries is sized incorrectly-The batteries will be under-charged if the solar
array is too small, or if the battery bank is too small, or if the usage is too high.
2. Solar panel’s problem - Solar panel can be seriously affected by the angle of the panel (as in winter months), minor
shading, high level haze (barely visible) and dust on the panel.
3. Battery’s problem - If the battery is going bad, a little charging or discharging will cause a large change in the battery
voltage. A battery short somewhere can also reduce the battery voltage.
4. Controller incorrect connection - Include reversing the polarity from the panels or batteries, or switching the array and
battery connections.
