Hey Barry, thanks for reaching out. Yes, there is a soft start that works with your Dometic FreshJet 5 with Heat Pump # FJX5557EHPWHCS. I recommend the SoftStartRV Soft Start for Single Zone Air Conditioner Setup # SSR54FR. It's compatible with electronically controlled rooftop units like your FreshJet 5 and works with heat pump models as well.

A soft start doesn't change how your air conditioner runs once it's operating, but it makes a big difference during startup. It gradually ramps the compressor up to speed instead of hitting it with a large surge of current all at once. That lower startup draw makes it much easier to run your A/C from a smaller generator or inverter, helps prevent nuisance breaker trips, and reduces the stress on the compressor each time it starts. It's one of the best upgrades if you're looking to get the most out of your electrical system while extending the life of your A/C.

Do you usually plug in to shore power? Or do you run your AC off A generator?
