Mounting your Inverter with Optional Brackets
The 200-400w TruePower Inverters have optional mounting brackets included with
them if you would like to permanently mount your inverter. Please attach as illustrated
and secure with screws.
Battery Operating Time
Operating time of your inverter is determined by the size and type of battery you use,
but more specifically it is determined by how much power you will draw. Follow the
below steps to calculate roughly the battery ampere-hour capacity you may require.
1. Establish how many watts each piece of equipment you will use consumes. This
usually can be found on the label of your power products. If only current draw is given,
you can estimate the watt consumption by multiplying current draw by 115.
2. Estimate the time in hours you will be running each power product between charging
your battery source
3. Calculate the total watt hours of energy consumption (power x operating time) using
the average power consumption and the total estimated running hours. (Power x
Operating hours = Watt Hours)
4. Now Divide the Watt Hours by 10 to determine how many 12volt ampere-hours will be used.
You need to have a battery or a bank of batteries with same ampere-hours you demand.
If the user has TruePower running off the start battery of your vehicle, we recommend
the user to start the vehicles engine very 30 minutes to recharge the battery. This will
help prevent any automatic shutdown of the inverter due to low battery voltage and
help ensure enough battery capacity to start the vehicle’s engine. The inverter’s low
battery alarm will sound when the battery drops to 10.5 volts and shut down at 10v. If
you are using the TruePower Bat’ Saver mode, the Low battery alarm will sound at 11.9
volts and shut down at 11.7v.
The TruePower inverter can be used with or without the vehicle’s engine running. The
inverter may not be able to operate while the engine is starting as battery voltage drops
substantially during engine cranking. The best battery setup we can recommend for
providing sufficient inverter capacity while protecting the engine start battery from being
overdrawn is to have a separate battery for starting the vehicle and to have a deep
discharge type battery or several batteries in parallel for powering the inverter if you plan
on running electrical products for extended periods of time on a frequent basis.

Fan does not turn on.
Possible Cause:
- The power rating of the appliance may be too low or the ambient temperature
is too cool.
Solution:
- No action. The fan will run at full speed when the inverter is powering a higher
rated appliance.
Fan runs all the time.
Possible Cause:
- The power rating of the appliance is too high.
Solution:
- No action. The fan will run at full speed when the inverter is powering a higher
rated appliance.
Possible Cause:
- The ambient temperature is high.
Solution:
- No action. The fan will run at a higher ambient temperature to keep the
inverter cool.
Low Battery alarm sounds continuously
Possible Cause:
- Bad wiring or connection
Solution:
- Tighten and clean all DC connections
Power tool will not start
Possible Cause:
- Large start-up (surge) current demand.
Solution:
- If power tool will not start, then proper sized inverter should be used.
