HOW TO CHECK BATTERY VOLTAGE
WARNING: DANGEROUS VOLTAGES PRESENT DURING THIS TEST, TRAINED
PERSONNEL TO PERFORM THIS TEST. CONFIRM THERE ARE NO FLAMMABLE GASSES
PRESENT WHILE PERFORMING TEST. ARC FLASH HAZARD – APPROPRIATE PPE
Solar System
❑
•
Use Voltmeter set to measure DC voltage
•
Place Red lead in terminal block 1 and Black lead in terminal block 2
•
Voltage reading must be between 11.5 and 13.5 VDC
➢ Note: If Voltage readings fail to meet minimum requirements,
•
Check Solar Panel power source:
o Confirm Solar panel is clear of any obstruction with the southern sky.
o Use Voltmeter set to measure DC voltage
o Place Red lead in terminal block 1 and Black lead in terminal block 2
o Voltage reading must be between 14 VDC and 17 VDC depending of solar exposure.
o If proper voltage readings are found on previous check, continue with troubleshooting procedure
o Use Voltmeter set to measure DC voltage
o Place Red lead in terminal block 3 and Black lead in terminal block 2 in battery enclosure.
o Voltage reading must be between 12 VDC and 14 VDC depending of solar exposure.
o If there are no areas of concern, please contact OGI Service Department for further trouble

•
Use Voltmeter set to measure DC voltage
•
Place Red lead in terminal block 3 and Black lead in terminal block 2
•
Voltage reading must be between 11.5 and 13.5 VDC
•
Use Voltmeter set to AC voltage
•
Please leads in terminal blocks L and N – reading should be between 120 and 230 VAC
•
Check Battery Status Lights on battery inside enclosure:
•
Red Light Solid – Alarm
•
Yellow Light Solid - Unit in Battery Mode
•
Yellow Light Flashing – Battery Charging
•
Green Light Solid – Unit Power On
•
Green Light Flashing - Overload
TROUBLESHOOTING
REQUIRED WHILE WORKING ON THE FOLLOWING:
follow trouble shooting steps below
➢ Note: If voltage readings fails to meet minimum requirements, check wiring
connections from the solar panel into the battery enclosure. The solar panel has a
junction box in the back side. Open junction box and check terminations. Note that
there will be power at the solar panel terminations, power source can not be
disconnected since it comes directly from solar panel. Follow proper procedures while
performing this test.
below:
➢ Note: If voltage readings fails to meet minimum requirements, check wiring
connections from the solar panel into the TotalArc enclosure terminal blocks and from
the solar converter SK-6 to the panel terminal blocks.
