...usage and unless there is a pms involved there's no chance of running two rooftop units on 30 amp, ordinarily (unless the rooftop has a softstart capacitor) a 30 amp won't support a running 15k btu unit and microwave simultaneously. I suspect running a 50 amp trailer through a 30 amp dogbone...
Education needed! What does "soft start" mean & what does it actually do? Maybe gradually increase the current flow at start up?
What are the benefits, other than what TJ just mentioned?:unsure:
Just ask this question with no details. 2014 Dynamax Dynastar 32XL. Installed lithium batteries and solar. Softstart on AC units. Would like to run unit while traveling from invertor. How is the best way to put AC Units on invertor circuit. They are only on shore and generator power currently.
...and it made a huge difference. Before the soft-start, our house lights would dim noticeably for an instant (kind of a blink). After the install, I never know when it starts. And, our heat pump service tech swears that using a softstart significantly improves the life of the compressor...
By replacing your startup capacitor with its much smarter electronics it lowers the amount of AC current required to start your air conditioner or heatpump by up to 60% to even 75%. So, let's say you are plugged into a 15 or 20 Amp circuit while moochdocking, you might be able to run one of...
Adding "soft start" to virtually any high-draw equipment is beneficial. We've had a large heat pump unit at the sticks-and-bricks for several years. Every time the unit started, the house lights would blink/dim momentarily. A couple years ago, the tech who does our annual service on the unit...
...already getting a bit warm. 30 amp only. We couldn't run both air conditioners. Kept flipping. Barely could run one.
We considered the softstart, but talked to some someone who told us not a good idea. Can't recall why. We decided it was just easier to stick to 50 amp campgrounds. This...
...an option for an overnight stay while on the road. As mentioned previously the start up of the AC is where you are probably getting overloaded. Last time I looked Softstart makes a dogbone version of their otherwise "installed at each AC" device, might be worth a look for use while traveling.
I start thinking if you feel it is soft on the ride a sway bar is in order. Soft meaning you feel the back end is kind of mushy and pronounced more so in curves. A nice big old sway bar from Helwig would be the key. Any soft ride (especially in corners ) would benefit most greatly from a good...
...generators are notorious for being over-rated. And, some ACs have been known to draw more than their rated power on startup. Using the softstart device will significantly reduce your startup (surge) current (Wattage). It does little to nothing to reduce running Wattage.
If I was looking...
...be able to get the second one started but most of the time you'll kick the breaker trying to start it. This is why some people buy the "soft start" kit for the A/C units. It keeps them from spiking the amps during the start so they can get by on 30 amps to run both A/C units. Without the...
After all that happened, I installed SoftStart on two of the most used AC’s.
Tightening the lugs in the transfer box should be done once in a while.
Also the AC breakers panel. I neglected it, and melted part of the panel $$$
You may need a full blown vehicle charger... sone "trickle chargers" wouldn't pump out much.
I haven't tried this... butbif you can start your coach, or start your coach with a jump. Let it run...and check the voktage on the chassis on your digi-level display. When it gets up around 13+...
Forget about a stand alone generator. Just get an F-150 PowerBoost HEV with the optional 7.2 kWh Propower on Board Generator option. You can even configure your tow to be fully powered with the air conditioners running in motion with minimal impact on MPG performance of the truck.
The...
Unless you have a SoftStart on the A/C, on start up the A/C electrical draw is excessive. As the A/C motors spin up the draw is excessive, once running the draw declines to rated draw. On startup the draw may exceed generator capacity, especially if there are other items running, like fridge...
I moved my Easy Start over to the new unit. (Dometic Freshjet 5) It started the first time with a 30A surge. The last one was 15A. It runs at 12A...So LRA is only 3 more amps. Amazing contraption. I'm hoping they offer an Inverter friendly unit. Australia is installing Dometic Freshjet...
...Westinghouse from Walmart. It has a remote start feature and is quiet. However, it will not start my AC unit consistently so I am adding a softstart device. It is to much for me to pick up and put on my truck but I would not go smaller unless you get units that can be paralleled. Depends...
Do you know if your charge bridge is working properly? It seems to me that the Lithium bridge may not be setup to provide the power to recharge.
A simple test would be to start the engine, put on high idle, and remove shore power. THen without any demand on the system (ie: turn of front air)...
