Quick Evaluation
Before Installation
Introduction
To check your inverter’s performance before installation:
1. Turn the inverter off (see page 14 for details). If the power source is a DC power supply, switch it off as well.
Power Source | The power source must provide |
| between 11 and 15 volts DC and |
| be able to supply enough current to |
| run the test load. As a rough guide, |
| divide the wattage of the test load by |
| 10 to get the current (in amperes) |
the power source must deliver.
≤ Cables to connect the power source to the inverter. Cables are supplied with the unit that are two feet long overall from the tip of the clamp shown to the stripped and tinned end for insertion in the Input End of the unit.
If user supplied cables are to be used, they must be as short and thick as possible in order to reduce the voltage drop between the power source and the inverter when it is drawing current from the power source.
If the cable suffers an excessive voltage drop, the inverter may shut down when drawing higher currents because the voltage at the inverter dropped below 10 volts.

2.Connect cables to power input terminals (see page 8 for details).
3.Connect cables to power source (see page 8 for details).
4.Check to make sure all connections are secure.
5.Turn the inverter on. If the power source is a DC power supply, switch it on first.
6.Plug in the test load.
The inverter should supply power to the load. If the inverter is not working properly, refer to the troubleshooting guide on page 20 or power and protection indicators section on page 16.
≤ A test load that can be plugged into the AC receptacle on the inverter for short term testing at a low power level. The following cables are recommended for testing low power level test loads only.
Test Load | Test Load | Minimum |
| Power | Cable Size |
100W # 16 AWG copper
250W # 12 AWG copper
500W # 8 AWG copper
USB Outlet
NOTE A USB device can be used to check the output of the USB Outlet.
