7. Troubleshooting
Problem / Symptom
Possible Cause
Solution
Buzz in audio system
Power supply in audio system does not filter
modified sine wave
Use audio system with higher quality power
supply
Television interference
Inverter is not (well) grounded
Make sure the inverter is well grounded
Other high power loads are operating
Switch off high power loads
Bad antenna signal or bad antenna cable
Verify signal and cable quality
Television too close to inverter
Move the TV set away from the inverter
DC cable radiated interference
Keep DC cables as short as possible
Low output voltage on voltmeter (192-208Vac)
Average reading voltmeter is used
Use true RMS reading voltmeter
Low output voltage and current indicator in
red zone
Overload
Reduce the load
No output voltage & voltage indicator in red
zone
Low input voltage
Recharge battery, check connections and
cables
Not output voltage, no voltage indication
Inverter switched off
Switch inverter on
No power to inverter
Check wiring to inverter, check battery fuse
Internal fuse open
Have a technician check and replace
Reversed DC polarity
Have a technician check the fuse ;
OBSERVE CORRECT POLARITY
No output voltage ; voltage indicator in upper
red zone
High input voltage
Make sure you are using a 12V battery ;
check regulation of charging system.
Permanent low battery alarm ; voltage
indicator below 11V
Poor DC wiring, poor battery
Check (& replace) cables and connections,
replace or recharge battery.
No output voltage, overheat indicator on,
load >3000W or 250A input current
Thermal shutdown
Allow inverter to cool down. Reduce load if
continuous operation is required
Improve ventilation, make sure ventilation
openings are not obstructed, reduce ambient
temperature
No output voltage ; overload indicator on
Short circuit or wiring error
Check AC wiring for short circuit or improper
polarity
Very high power load
Remove or reduce load
8. Maintenance
Your
PI3000B & M
requires very little maintenance. Clean the exterior periodically with a damp cloth to prevent dust
and dirt accumulation. Clear the air intake on the rear panel and air exhaust slots on the front panel especially. A
regular maintenance check is recommended, and all visible screws on the unit should be tightened periodically.
