5000 Watt / 10000 Watt Power Inverter  by Wagan

TEST RESULTS: WAGAN 5000 INVERTER         09-12-2003

Wagan Corporation:

Below are the results of the 5000Watt/ 10000Watt Wagan Power Inverter. The retest was done using the same batteries and equipment as in previous test on 12-16-2002. The retest was conducted using 2 gauge wire as per your factory instructions, and 3/0 gauge wire.

Metering Equipment: True RMS Fluke 76 Meter and Fluke 41 Meter.

Power Source: (6) Interstate Batteries, Marine/RV deep cycle. Model# SRM-4D / 1645 CA / 1314 CCA Batteries rated at 25A each for 6.5 hours

Set-up: Batteries (6) wired in parallel using 3/0 cable, capable of 150A.
Two (2) power strips coming out of inverter connecting six (6) 250/500W halogen lights

Battery to inverter connection:
Retest #1 - 2 gauge
Retest #2 -3/0 gauge

Initial battery reading: 12.1 VDC across all batteries
Initial inverter output reading: 118.3 VAC.

Quick and simple results;

1) As tested with 3/0 wire, inverter had no problem and no alarms were sounded or indicated.

2) 5000W plus no problems at all. Stopped tested at 5030W as in previous test (12-16-2002).

3) Testing with 2 gauge wire, volt indicator started to flicker between green and yellow at 3000W.

4) 3000W, voltage at batteries reading 11.4 VDC and 115.7 VAC at the inverter outlets. (2 gauge wire)

5) At 5000W / 2 gauge wire, inverter alarm in the yellow. Inverter output 113.4 VAC and batteries reading 11.2 VDC. All items used to test load on inverter are operating. Lights did dim when inverter load was increased to 5000W from 3000W.

The conclusion reached, larger capacity cables enabled the inverter to handle the advertised specification with no problems. 2 gauge wire was capable of handling 5000W but only marginally.
