Step 1: Check environment
Ensure that the environment is clear of all hazards including explosive gases
before opening the DataSite configured panel. Refer to NFPA 70E, 2004
Safety Guidelines when servicing the DataSite configured panel equipment.
Step 2: Check solar panel output
Check the solar panel output to ensure that the solar array is connected and
working properly.
• Disconnect the solar panel from the DataSite configured panel and
measure the voltage of the solar panel while sunlight is striking the
panel. In sunny conditions the open voltage of the solar panel should
read between 18…24V DC. A lower value could indicate a problem with
the solar panel array.
Step 3: Check condition of batteries
Check the condition of the batteries.
1. Check the connections for the battery and make sure that all terminals
are torque to their specified ratings and that no wires are cut or frayed.
2. Create a load on the battery by using a battery load tester
(1)
. If the
battery test fails, replace the battery.
If the battery is working properly, move onto Step 4: Test condition of
power transistors in solar controller .
(1)
Use a battery load tester designed for Lead Acid Batteries. Follow the instructions of the load tester to check
the condition of the battery.
