Powerjack: how to change permanently the output from 60Hz to 50Hz please ?

<< < (2/2)

Pete:
Hello Germain, glad to hear that you managed to get the inverter to behave and stay on 50hz.
Where did you find the information on changing the power output.
As my inverter manual is actually not the correct one for my inverter ( no information on frequency changes etc) it has no information on changing power.
Good to hear that you found the info you needed
Pete

Hi Pete,

I got those informations by contacting directly Helen (elfriede@163.com) at youlung.com !  ;)

I'm sure she can helps anybody about any Powerjack issue...

Cordially,
Germain

Pete:
Thanks Germain, that is the first bit of information I have seen about the company that makes PowerJacks.
I have never seen anything in their manuals about who makes them or any contact details.
It is great to know that now.
Hope yours runs for a long time.
I have had a good run with them over the years. I have had a PowerStar W7, 12 volt that i added an inductor to to reduce idle currents, it still works great, I have a 5000 watt PowerJack that has never had any problems.
Recently I went over to a 24 volt system and now have the U Power 8000 watt. After I took the cover off and put a loose screw back in, corrected the output polarity and found a loose plug and socket it is going well. I am happy with it as it runs my air compressor, wood splitter and water pump well. I don't use them for a long time but it is lovely not to have to start a noisy generator just to do a quick job or two.
Thanks for your information
Pete

Hi again Pete,

By looking on Internet (Google is your friend  ;)), you may find find several Web sites about the Powerjacks, for example on https://www.powerjack888.de/ or https://www.powerjackpowerinverter.com/ !

Las but not least, you will find a lot of videos about them on https://www.youtube.com/results?search_query=powerjack

I run my inverter into a motorhome and I'm able to heat instantly water through an electrical faucet (3200 watts) too !

Cheers,
Germain
