EasyStart™ 368 Soft Starter for AC Units 30K to 48K 230V - ASY-368-X48

EasyStart by Micro-Air is the most effective way to reduce current draw of marine air conditioners or refrigerators. It was designed with a 4-part start ramp sequence that is self-optimizing, resulting in the lowest possible start-up current. It is compatible with all boat air conditioning brands like Dometic, Webasto, Cruisair, Marine Air, etc. EasyStart can deliver a start current reduction of up to 75% of a compressor's LRA (locked-rotor amperage) allowing your marine air conditioner to work in situations where it otherwise would not have functioned. 



Sart-Up Algorithm for Start Surge Reduction

  • Lab tested CE Compliance
  • Average start surge reduction to 65%
  • Sophisticated, auto-learned 4-part start-up algorithm
  • one time learning algorithm for better shore power/generator transitions. 
  • Individually optimized profiles for 50Hz and 60Hz 
  • Low sensitivity to momentary voltage deeps during start-up
  • Auto-bleed of run cap voltage and compressor energy during shutdown
  • Reliably starts any 115V compressor on a Honda EU2000i in ECO Mode.

    Great product

    Posted by Matt E. on Nov 23rd 2022

    Installed on my 4 ton Bryant AC unit with a Locked Rotor Amps (LRA) rating of 124A. After 5 learning runs the peak amperage dropped down to around 26 amps, based on the EasyStart bluetooth app. Package only comes with the unit itself along with a manual. You will need to buy additional connectors (female spade -- blue and yellow) and a butt connector (yellow). The unit did not fit inside my AC unit panel, so I had to mount it outside on a stucco wall. I used a step drill bit for making a hole in the AC panel door, a 1/2" strain relief cord connector (Halex 1/2 in. ACC Non-Metallic Strain Relief Cord Connector) , and 4 wall mounting screws. Water Yacht Solutions had the best final price I could find for this unit. Thank you!

    Micro-Air EasyStart

    The price was the lowest I found, and the item was received in 3 days. I bought a new generator, but it was unable to start my 3 ton geo-thermal heat pump. After installing the EasyStart, it started easily. Highly recommended.

    83 amps to 27 amps! One star off because my installation was more complex than example video.

    Easy start for a 3 ton unit

    Posted by Al on Sep 20th 2022

    This sucker works good and cut the starting amps in half. Water Yacht solutions is a good place to purchase it from and cheaper than micro I’m very happy with the soft starter and it was fairly easy to wire up.

    Fast shipping & great product. Installed on my central air 4 ton unit and dropped my inrush amps from 56 to 29amps and can now start the a/c easy with my generator. Installation is easy and there are a ton of Youtube videos on how to install it if you need a visual aide.

    Made a big difference

    Posted by James Collier on Jul 12th 2022

    This is a bit expensive but worth it. Wiring instructions were easy to understand and once it learned the startups, it took my inrush current from 60 amps all the way down to 16.4. In a power failure, I’m using a Westinghouse wgen9500DF on propane to start this 3 ton A/C & now the gen barely notices when the compressor starts up. Compressor is also much quieter when it starts so should add years to its life. Overall I’m happy with the purchase.

    Works as advertised

    Posted by Manny on Jun 7th 2022

    I wanted to use this on my 3.5 ton A.S. A/C unit so I could limit the starting current for use with a generator. I was concerned that this might not work, as online docs for my unit state that it uses a "non bleed TXV". Contacted the factory and they said that although these types bleed down more slowly than the orifice types, they have success in 99% of these situations. They were right! Plunked down the money (by the way this site had the cheapest online price I could find), installed it (fit inside the cabinet) and it worked fine. I did not have the means to measure inrush current, but the nameplate on the unit stated LRA was 109 amps. The first learning cycle showed starting amps 50, and after the remaining 4 learning cycles it was down to 30. Runs off the generator with hardly a blip.

    Great product. Fast shipping. Easy installation. No more Compressor clunking on and off all night.
