I installed an SPP5 on the exact same LG air conditioner and had good results. I can't give you exact amperage numbers before and after, but my generator starts the AC unit MUCH easier after the install.

[@ParkRoadGuy]

Did you hook yours up the same way as this video?

[@SlipFitGarage]

@@ParkRoadGuy Yes, Sir.

[@macelius]

I picked an off-brand one up to check it out, the wires seem to thin to supply much if any significant amperage, also left it in my old Coleman Mach till it gets a real hard start kit.

[@over-there]

A 5000 btu ac doesnt use 21 amps, should be less than 10 amps when running. Good idea to check amps it in a wall socket, problem may be with inverter, check voltage out of inverter with a meter. Maybe need different starter, or inverter, but solve the amp thing first.

Awesome project, i am going to do something similar for my land rover house battery. I am starting with 1.5kw for a fridge and a small inverter. How are you using the rc charger? how long does it take to charge?

[@james10739]

I think those are designed to let more power flow for compressors that are having problems but we will see what happens

[@mIkeyGermita]

How much did that battery bank cost you and how long will it run the A/C for? Looking to build the exact thing you did here and potentially add some solar panels.

[@enochjames5452]

You hooked it up wrong on the capacitor

[@onecrazywheel]

These are rated for. 0.5-10 HP. Is your little fan motor on this window shaker less then 0.5 HP? I'm sure that could be an issue. I have this SPP6 Supco Hard Start on our 2 Ton A/C condenser outside and it works awesome. That is probably the better application. 👍

[@drsolar]

You did not see a surge. That is what the capacitor absorbs

[@mckrackin5324]

The 21 amps IS the surge. Once running, that AC unit runs on about 5 amps or less.

[@MastaSquidge]

That's absolutely not how that works.

[@xiradio]

That hard start is probably rated for a much larger compressor. You need a very small hard start to work correctly with that unit.

[@arminius301]

I was going to run that same LG air conditioner on my LiFePo 100ah battery with a 1500 watt inverter. Are you telling me the surge is actually 21 amps (21x115V=2415 Watts @ surge)?

[@burnedpixel1598]

It's not about electricity economy or something like this. When ur AC starting the compressor, it will discharge this capacitor for use his energy just for start and not make an impact to power system. When ur AC already working, u will not see any effect...

[@huskypup3489]

The peak current didn't change because the inverter still has to charge the starting capacitor. You would need to add capacitance between the inverter and AC unit. That way, the capacitor will provide the 20A peak instead of the inverter.

[@Bugs11000]

Something is not right. I live in a van and have had an air conditioner now for 5 years. A 5000 btu air conditioner pulls at least 40 amps on a 12 volt system⁶. The rating of a 5000 btu air conditioner at 120 volts is only 4 amps. If it functions on a 12 volt system than the amperage has to go up ten times 12 volts. That's why something is not right with that air conditioner. Now, I have a 6000 btu air conditioner and it draws 50 amps/hour.

[@nathang.1744]

sounds like compressor is flooded on start up

[@kaden4418]

Why didn't you install the air conditioner?

[@mIkeyGermita]

Why would it need to be installed? For the purpose of the video I don't see how it makes any difference.

No difference at all it was actually worse
