It's not necessarily an app requirement for location to be on. My Android app for my LiFePO4 BMS won't connect unless location services is on. It's an Android thing. I doubt that the apps are communicating anything back to the app vendor.

Brantel, what data do you see in the app for the MicroAir? The data may not be that much different that I can get from my inverter. Amps and watts. The data in the app would have to be compelling to pay extra for that feature. Can the app connect to the MicroAir even if the air conditioner is turned off? It probably isn't much of a draw, but I'm watching every watt that is pulled through my inverter.

I installed a EasyStart 364 on my coleman ac unit on my truck camper. I use a 2000w Yamaha generator. Up to around 2,000' (depending on temp) the gen would work fine with the A/C if camper battery was full up and no loads prior to soft start, above that elevation, the generator would overload and kick out with a warning light. Now, I can be good up to ~6000'elevation, and if the compressor refrig kicks on or another load is added, the soft start will sense the overload and turn off the compressor prior to overloading the generator and causing it to fault, and will allow restarts every 5 minutes until successful pulling the A/C load.

I am very happy with the soft start.

First I'm a retired from my electrical, refrigeration and HVAC business and I just suffered through their video and they proved what I've known for years that hard start kits are junk and are no replacement for factory start caps and relay. You may not have noticed but when he did his test the fan motor and compressor are starting at the same time giving you two startup amp draws that will drop the voltage on and line causing higher compressor current draw. Their device delays the compressor startup allowing the fan motor start current draw to stabilize before the compressor starts. I would have liked to see him test the factory setup with the fan motor already running, I'm thinking the start current would be greatly reduced because of voltage drop.

If you can't run your air on your generator and it has a factory start cap before you spend $300 turn your fan off auto to on and then turn it to cool and see if it will start and run.

For an iPhone app to even have access to your location information, you have to give it permission to do so. The EasyStart App does not even ask permission because it could care less about your location.

The EasyStarter is not a "Hard Start" device. It is a soft starter. Big difference.....

The data:

The difference is that this data is captured at very high speed and displays the real peak's. You also get some data like number of starts, state of the soft starter, faults, lockout delay etc. To me this option was so cheap to add on it was a no brainer to get visibility into the box instead of relying on status lights that require the cover to be removed from the AC and to be on the roof watching it. Setup was dirt simple since you don't have to see the unit at all.

The BT only works when the compressor is on since it gets its power from the compressor power lead.

Nothing wrong with having the ability to see info at your finger tips while sitting in the lazyboy recliner, what you showed can be seen through my inverter.
Here is a post I did awhile ago after installing and doing the learning cycles.
https://www.ford-trucks.com/forums/1...l#post19298701

Nearing 2 years of use now and while I sit in my lazyboy I can see my display for my batteries across the room and as Denny mentioned the fan comes on first for a few seconds then I can see the draw on my batteries as it slowly ramps up to operating specs. I use my air conditioner more off of solar/ batteries than with the generator.

Thanks! The line frequency is an interesting data point. I've never tested mine. Heck, I've never tested that data point on anything! But having it easily reported like that could be a handy way to tell if you have a crappy inverter or generator.

Jim I'm sure somewhere in your menu for the victron you can see it.

Here is a quick look from the inverter moments ago.



When the gen is hooked up or power pole and passing power through it will show incoming Vac/ Hz .

I'm sure there is a frequency readout in the Victron Connect app. Somewhere. But having an independent report of it wouldn't hurt. I don't know the AC side of things very well, so I don't know how you could screw up frequency. Voltage I understand how to screw that up.

In the big scheme of things all these extra things that can be seen are cool in the beginning but as time wears on some just don't get viewed often unless scrolling by them.

When something stops working unless theres a recorded long period of history these screen are just live time which can help troubleshooting.

Yeah, the Bluetooth for the Microair does seem like a shiny object. Cool to geek out on, but not necessary.

Using the menu within the remote for the inverter it can be seen besides many other things.

Here I just set the air conditioner to cycle at 75f ( a little later it will get lowered to 73f) it will run for a short bit then cycle off. Off time the batteries go back to charging.
This is after it starts running. Micro-air makes it a gentle cycle.


This is after it cycles off and solars charging the batteries again.
