What's the model of the 3kW inverter? Doesn't it have some terminal for directly wiring it? Those appliances you mention shouldn't blow a 13A fuse though. Assuming 200W for the fridge, 200W freezer, 100W TV and 500W washing machine, that's 1kW. (4A at 240V).

Alright I decided to open the inverter to see what I could do with the temp sensor. The terminals for the AC outlets of the inverter are super loose, they popped out of their place when I removed the front cover of the inverter. Also the N and L cables are flipped around, the PCB says that...

Alright I can confirm that the issue is the temp sensor, because now that it is cooler at night the fan does stop, however it still cycles on and off every now and then because the inverter warms up a bit when idling to trigger the fan threshold. Kinda odd that the inverter doesn't a varible...

Alright I bought the inverter and I finally have it, things are not looking great. With no load the fans are at full power, and the internal temperature display says 107F when the actual temperature is about 90F, maybe this is why the fans are at full blast all the time, I will wait for the...

Can this inverter really work down to 9.5V? I might get one to use it with a 3S pack.

Alright I think I'm a bit late to this but I'll just leave a diagram and explanation because really a lot of the things that have been said here are very confusing if not completely wrong, even the diagrams provided by signature solar don't explain it. If you have a 230V inverter with a N to G...

You had the capacitor where the bypass diode would be on my diagram right? All 6 turbines are of the same voltage? You made sure that you did not wire any of the capacitors backwards right?? Because that would explain the stalling. Try an add the bypass diodes, because that way the bridge...

I assume that by DC step down transformer you mean a DC-DC converter. Buck converter in this case. This would be a non isolated power supply. You can do it but a failure in the converter will very likely result in massive damage to the battery and everything that's connected to it and a fire...

You can try to rectify the output of each wind turbine to DC right at the pole then wire all of that DC in series. And each rectified DC from each turbine gets its own bypass diode, just like series PV. Here's an example with 3 turbines: Also the bypass diode isn't really 100% needed because...

You can use an ATS that switches the neutral to avoid that problem. I have this one cheap 3P ATS 110V coil from aliexpress: https://streamable.com/dzkzvu It is also surprisingly very fast at switching. It switches a subpanel where I have most general purpose receptacles and lighting circuits...

US electricians dont test for impedance unfortunately. UK electricians can tell if there is a loose connection in a circuit if they notice that the loop impedance between N and L isn't the same. US electricians could do the same even without ring circuits, just find the last receptacle of a...

There is nothing wrong with ungrounded systems, people mistake grounding with bonding all the time, it is the later that provides shock protection. Having an ungrounded system means that it behaves like an isolation transformer, there is only 120V between L and ''N'' (N is not the right term...

More like 1.5 kW total, why should I have to worry? Did you not see the review? The thing is built better than most inverters of that range, similar inverters would just use the thin metal casing as heatsink for both sides for example, the H bridge fets would be less capable as well. '''I've...

The inverter can power it no problems, it is one of the reasons why I have that specific model, there's a nice 4 part review of it on youtube: We've been using it since 2018 and has performed great, and it has overloaded just once and it was because we tried to run the coffee maker with the...

I used a TOCT1-63 2NC 2NO contactor, rated for 400V. It is just one contactor, are you using just one contactor? Or you have two electrically interlocked contactors? The later of course will have no problems. The Inverter is a Bestek 1000W MSW, it is powered by a 3S lithium battery (10.95V...

I tried using a DPDT relay as transfer switch, it killed the inverter when running inductive loads as it would arc across while switching. I tried adding some snubbers but that didnt help. (The inverter is surprisingly easy to repair, the only thing damaged are AC switching transistors). It has...

Without it. Are the RCDs not tripping when you press the test button? Looks like this is the UK, there they have what is known as TT system, they do in fact sometimes use the earth as EGC, but because the earth resistance is too high the upstream breaker needs to have RCD protection...

That means the issue isn't a open ground. What's the model of the inverter? Pure o modified sinewave? What happens with the UPS exactly?

Automatic transfer switch? Are you sure it only switches the hot? If you have a non bonded inverter (check the continuity between its output terminals either way), if the transfer only switches the hot you should not have an open ground because one conductor of the inverter will connect...

Me? So far what I've seen is that people don't understand the difference between grounding and bonding. In fact lets start with this comment which was the very first I found when searching for open ground, which is from you...

You're saying that if the resistor and the potentiometer were not present (wiper fails to make contact) the inverter will still work? Alright then, it just means that the low voltage protection would be disabled, not much a problem if you have a bms or another protection circuit before.

Alright. No, it wont work if the inverter is isolated. You can test this by yourself, wire a lightbulb between the earth and ''live'' terminal of the gfci, you will see that it doesn't trip and that the lightbulb wont even light up.

What do you mean the UPS doesn't work? The UPS refuses to turn on? O just gives a warning about open ground? The UPS should work regardless if there's ground or not, if it in fact doesn't want to work it would mean that the UPS cannot be use in old houses that were updated to open ground...

Why are you grounding the system exactly? (what does SCC mean?) If the output of the inverter is isolated (99.99% do) there's no point of grounding anything, would be the same as grounding after an isolation transformer. With the inverter turned off check if you have continuity between the...

You may want to solder the wiper to one end of the pot so that if the wiper fails to make contact (and believe me they do) it defaults to the resistance of the track instead of failing open circuit. This way you have it can either result in the inverter to stop working (thinks the voltage is too...

This video right?

Notice, a 100W solar panel produces about 500 Wh in a day, those run for 80$. The turbine would only need to produce an average of 20W all day for it to produce those 500 Wh.

Get a DC Clamp meter and see how much current it generates. The overspeed protection shorts all 3 phases (if it shorted one phase the turbine would wobble as it would throw it out of balance). I have the same one as yours, just with 3 blades and 12V version, the thing needs to speed up to start...

If it is going to be a VAWT, it has a to be a Darrieus type, most VAWT on the market are Savonius design and are very inefficient, and in fact some in the market don't produce any power at all. Check your surroundings, I can't trust my weather report for wind speed, sometimes it says that the...
