It cuts the compressor's start-up power surge by as much as 75 percent, so your AC stops tripping breakers and stalling generators. If you camp off a portable generator or on tight 30-amp shore power, it's the part that finally lets the air conditioner run.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Dometic SmartStart is a soft starter built for the FreshJet 5 Electric Series rooftop air conditioner. It goes after the single biggest power draw in your RV, which is the moment the compressor kicks on. That inrush surge is what trips pedestal breakers and stalls generators before the cabin ever cools. SmartStart smooths the spike out, cutting start-up power demand by as much as 75 percent so the AC comes to life without the hard jolt.\u003c\/p\u003e\n\u003cp\u003eAnyone who's tried to run rooftop AC off a small portable generator knows the drill. The generator handles the steady running load just fine, but the compressor start-up surge overwhelms it and the unit shuts down before you feel any cold air. SmartStart changes that math. By dropping the start-up spike, it makes it realistic to start and run the FreshJet 5 Electric on smaller generators that simply couldn't swallow the raw inrush before.\u003c\/p\u003e\n\u003cp\u003eOn 30-amp campground service you're always doing amperage math in your head. Fire up the microwave, the water heater, and the air conditioner at the same time and the breaker pops. Because SmartStart shrinks the compressor's start-up draw, you free up amps for everything else on the circuit, and you stop babysitting which appliances are allowed to run together. That's a real quality-of-life change on a hot afternoon.\u003c\/p\u003e\n\u003cp\u003eIn bigger rigs with two rooftop units, staggering the thermostats isn't always enough. Two compressors trying to start close together can spike well past what your shore cord or generator wants to deliver. Adding SmartStart to the FreshJet 5 Electric keeps each start-up gentle, which matters most in the heat when both units cycle constantly and every start is another chance to trip the supply.\u003c\/p\u003e\n\u003cp\u003eThere's a comfort angle too. A hard compressor start sends a jolt through the whole unit. With less power slamming in at start-up, the FreshJet 5 Electric spins up quieter and with less strain on the compressor and its wiring. Over a long season of daily cycling, an easier start is easier on the hardware, and that tends to show up as fewer nuisance faults down the road.\u003c\/p\u003e\n\u003cp\u003eThis is the FreshJet 5 Electric Series version, Dometic part number 9630001951. It's matched to that air conditioner's electrical system, so you're not guessing at compatibility or splicing in a one-size-fits-all module. The unit measures 12-1\/4 inches long, 7 inches wide, and 5 inches deep, and it wires in as part of the air conditioner's 120-volt circuit rather than sitting somewhere out in the coach.\u003c\/p\u003e\n\u003cp\u003eInstallation happens right at the air conditioner. The module ties into the FreshJet 5 Electric's own wiring, so the start-up management is built into the unit's circuit instead of bolted on as an afterthought. Plenty of owners have it added when the AC goes in, but it can also drop into a unit that's already up on the roof.\u003c\/p\u003e\n\u003cp\u003eIt earns its keep based on how you actually camp. Full-hookup resort with 50-amp service every night? You may never notice it working. Chase dry camping, state parks with thin power, or a portable generator in the driveway, and it moves from a nice-to-have to the part that finally lets you sleep in a cool rig.\u003c\/p\u003e\n\u003cp\u003eOne honest reality check on what it does and doesn't do. SmartStart doesn't make the air conditioner colder, add BTUs, or change how the thermostat behaves. It won't turn a worn-out compressor into a fresh one. What it does is one job well. It takes the violence out of every start-up so your FreshJet 5 Electric plays nicer with limited power, and for anyone who camps off generators or on tight shore service, that's the line between cool air and a tripped breaker.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eCuts air conditioner start-up power demand by as much as 75 percent, so the compressor surge stops tripping breakers and stalling generators.\u003c\/li\u003e\n  \u003cli\u003eBuilt specifically for the Dometic FreshJet 5 Electric Series and matched to that unit's 120-volt electrical system for a no-guess fit.\u003c\/li\u003e\n  \u003cli\u003eMakes it realistic to start and run rooftop AC on smaller portable generators that couldn't handle the raw inrush before.\u003c\/li\u003e\n  \u003cli\u003eFrees up amperage on 30-amp shore service so you can run the AC alongside other appliances without popping the pedestal breaker.\u003c\/li\u003e\n  \u003cli\u003eSofter start-up means less mechanical jolt and a quieter spin-up every time the compressor cycles.\u003c\/li\u003e\n  \u003cli\u003eReduces reliance on shore power, a real advantage when you're dry camping or parked where the power is thin.\u003c\/li\u003e\n  \u003cli\u003eCompact 12-1\/4 in x 7 in x 5 in module wires directly into the air conditioner's own circuit.\u003c\/li\u003e\n  \u003cli\u003eGenuine Dometic part number 9630001951, engineered for the FreshJet 5 Electric rather than sold as a universal add-on.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Dometic reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003cp class=\"nvn-trust-note\"\u003eGenuine Dometic FreshJet accessory, matched to the FreshJet 5 Electric Series air conditioner.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat does the Dometic SmartStart actually do?\u003c\/summary\u003e\n    \u003cp\u003eIt's a soft starter that reduces the power your air conditioner demands at the moment the compressor kicks on.
