Battery Maintenance
Periodically, check the batteries to make sure they are good condition. Check the terminals for
corrosion and clean them with a wire brush if necessary. If the batteries are flooded lead-acid,
check the electrolyte levels every month and top off with distilled water if needed. Finally, check
the battery voltage in accordance with the manufacturer’s specifications.
Inverter Maintenance
Little maintenance is needed to keep the TruePower Plus Series Inverter running properly. To
keep the unit running optimally, you should:
- Wipe the unit’s exterior with a damp cloth to clean off dust buildup.
- Check that the DC cables are securely connected and the fasteners are tight.
- Clear the ventilation holes of dust buildup.
- The GFCI outlet must be tested monthly. See page 18 for proper GFCI testing procedure.

Troubleshooting
WARNING
ELECTRICAL SHOCK HAZARD
Do not disassemble the TruePower Inverter. It does not contain any serviceable parts and
attempting to service the unit could result in an electrical shock or burn.
Failure to follow these instructions can result in death or serious injury
How to Troubleshoot Common Fault Conditions
This section details how to troubleshoot the TruePower Plus Series Inverter. Follow the process below to
narrow down the cause of unit fault conditions. Go through this process before contacting customer service.
1. Check for any fault messages on the unit display screen. If a fault message is displayed,
note it down before proceeding further.
2. Note the conditions around the time the fault condition occurred. Record the following details:
- Battery voltage at the time of failure
- How many watts the inverter was putting out
- Extreme environmental factors (ambient temperature, vibrations, moisture, etc.)
3. If no fault messages are displayed, check the installation:
- Is inverter properly mounted and located in a clean, dry, adequately ventilated environment?
- Is the battery in good condition?
- Are the DC and AC cables properly sized, in good condition, and have clean and tight connections?
- Have any circuit breakers tripped?
- Have any fuses blown?
4. When steps 1 through 3 have been completed, contact customer service for further troubleshooting.
Be prepared to provide information surrounding the unit failure as well the unit model and serial number.

Action
- Check battery voltage and recharge if needed
- Check for proper DC cable sizing
- Check for loose connections and tighten if needed
- Charge batteries to clear fault
- Check battery voltage and recharge if needed
- Check for proper DC cable sizing
- Check for loose connections and tighten if needed
- Charge batteries to clear fault
- Check for other DC inputs, such as an over
voltage alternator, and disconnect if needed
- Decrease input voltage to clear fault
- Reduce the loads connected to the unit AC output.
- Check for proper ventilation to the unit and remove
any obstructions
- Check the ambient temperature and move the
unit to a cooler location if possible
- Push button twice to clear fault
- Reduce the loads connected unit AC output
- Check for loads that have a high surge & remove if needed
