General testing requirements before final connecting
Always test outdoors under good sunlight conditions.
1. Test solar panel for voltage
Use solar voltage tester or Voltmeter to test the panel, positive to positive and negative to
negative, and observe open voltage which could range from 16 Volts to 24 Volts.
2. Test connection to solar charge controller for voltage
Connect solar panel to solar charge controller, measure the open circuit voltage at the
battery side of the charge controller which is 5-10% lower then solar panel and range
from 15 Volts to 23.5 Volts.
3. Connect charge controller to PowerHub 1800
Disconnect solar panel to solar charge controller and switch off the PowerHub 1800 with
battery inside if switched on. Connect solar charge controller to PowerHub 1800 and
make sure the correct polarity connection, positive to positive and negative to negative.
Always connect charge controller to battery first and remove last.
4. Connect charge controller to solar panel
Connect the charge controller to solar panel and switch on the PowerHub 1800, the
charge indicator, green light, of solar charge controller would be on and the battery
capacity indicator of solar charge controller would light as per the batter capacity.
If all testing results could be within the above ranges, the solar system could be normal
and charge the battery. If anything wrong, repeat above connections and retest. Finally,
It's common to have 12 battery issues such as dead cells or non-chargeable battery
problems.
