KINGS 3000W INVERTER REVIEW

WATCH TILL THE END TO SEE THE FULL LOAD TEST RESULTS.

[PowerPaulAu]

Not bad, I'm surprised at how well it worked.

The 3050w load through the BMS is probably correct, but the output of the inverter will probably be about 10% lower.

Glad to see the Muller BMS is working well too, I have been meaning to test mine, but I may need to pass it onto someone else as I don't think I will really have time.

The jumpy current reading will be a result of the sampling rate of the meter and noise from the inverter. This is something Andy has shown a few times. There's no easy way to avoid it (at least with consumer grade equipment) and it makes measurements awkward. You'll find a purely resistive load like a fan heater, kettle or halogen lights (who has those now though) work well for testing loads. But what you ran is probably a better indicator of todays gear because most of what we use now has some sort of PWM type power control. The things you ran were mostly resistive, but if you run that heat gun and a light from the inverter, you'll see the light flickering (it'll happen at varying points in the temp and fan speed).

I actually suspect the Kings and Renogy inverters are very similar inside. They share a lot of the same features and even the mains sockets are identical.

yeah my kings 3000w does a great job, my biggest problem is voltage sag from the agm batteries, you basically need 300ah of them before the sag isnt too bad
next upgrade is lithium
ive hit my inverter with well over 3500w load and it handled it, it was hooked up to 7 x 100ah agms and there was still really bad voltage sag
ive run the welder off it.. it didnt care
2300 water pump with a startup curent of over 20 amps and it ran fine... for the money the thing just works

3000VA Victron couldnt run our 2200W hoist, we figured based on calulation we would need around 3700VA but tried anyay as we already have the Victron inverter. I'm wondering if something as budget as this would likey do the job - your thoughts?

What size of battery are you using?
You reckon that inverter can run the heater in the tent when you go winter camping?
Cheers

Which Kings inverter should I get to pair with their 120Ah lifepo4 battery? The 1500w jobby?

Also, do you know if a Bluetooth battery monitoring system I can use on my phone, like you are, for my battery?

[blakee]

cheers for the vid mate, what monitoring system are you using that goes to your phone? I was tossing up redarc redvision/bms but might not have the budget for it yet

[paulbower]

Can you please show us how you made your "Soft Start" circuit that you used in this video with the blue and white wires

[lexicase]

I must have got very unlucky, i got the 1500w version of the kings inverter and it ran a 140w load (yeah 140, not 1400) for 35 minutes and let the smoke out, and dripped capacitor electrolyte everywhere. Thankfully kings took it back and gave me a refund, but im glad the 3000w one you got seems to do the job ok.

[russellcox]

New to your site, what size battery did you have with the test. I have a 3000w inverter and looking to upgrade from AGM battery to 300ah Lithium to run Caravan Fridge and A/C at the most power draw at any one time. A/C would be only to cool van down, 2-3 hrs. Cheers Russ

Do the cooling fans push cool air into the inverter ?
Or extract hot air ?

[Adventure-Storm]

Good test. I have the same inverter in my caravan.
Do your fans turn off.
On my inverter, if the fans come on they never turn off until I turn the inverter off, even if the inverter sits with no load for 30 minutes.
Is that normal for this inverter?

[starrkirk]

Does yours make a slight buzzing noise when turned on under no load?

[donnastein]

Great video, can you please tell me why the breaker needs to be as close to the battery as possible?

[TA_Artarmon]

3000w out the battery/bms doesn't necessarily mean the inverter is putting out that much. Conversion inefficiencies, fan, heat etc may mean it's actually putting out as little as 2700 on the 240volt side... would have liked to see 3000w continuous output on the actual output side

[fokcuk]

Burning question I have been breaking my head with - does it need grounding?

[sambaaxe]

Is that Kings inverter still working well for you?

[Jezzermate]

In regards to off grid systems in caravans/vehicles - seeming a live chassis from faulting appliance can kill you without a protective device, using a portable RCVO plugged into the 240v output will protect, but because there's no earth to ground, YOU will be it. This should cause the RCBO to trigger but ut could be too late.. If you installed an earth stake from inverter chasis it was have tripped without you in circuit. Just a friendly reminder to all that 240v is 240v, it's dangerous and without a protective device or ground you're dicing with death

[adriaandebruyn]

Has anyone ever performed an EMI/RFI test on this unit, I found the recently tried Powertech 2KW inverter extremely noisy on HF.

[hannesnel]

If only if it had 240volt terminals to connect to a rv 240 built in system

[pmacgowan]

PowerPoints are upside down because China uses our PowerPoint, but upside down. So it means the inverter is Chinese made
