I’ve been considering adding a soft start for some time now. I recently noticed a large influx of competing models to the original Micro-Air. Of course, most of them are made in China with questionable warranty and reputation. Then I noticed the SpartanStart – Soft Start. I did a search here and did not see any reviews or comments. I promised Gary at Inverters-R-US that I’d write a review here after installation. The SpartanStart is made in Australia and comes with a 3-year warranty. Sold by Inverters-R-US either thru Amazon or direct. The price was very appealing at $180 vs $300 for the Micro-Air. Plus, I ordered direct and was able to get 15% off with LOA discount so it was $162 shipped (plus tax).
The unit seems high quality. I installed and tested it the other day using my Power Watchdog to view watts and amps, first with a 20-amp shore power line. It was a very easy installation connecting the unit to the Common/Run/Start wires to the compressor.
I can say that it performs very well and eliminated any surge upon start-up. The watt consumption slowly builds.
I then connected to my Champion 2k Watt Inverter and turned off the converter circuit for the initial test. It started and ran the 15k BTU Coleman Mach without any issues. I started with the fan-low first then to AC-low/AC-high and then direct to AC-low/high. No issues and ran fine. The inverter was not struggling at all.
