After connecting eco flow to hook up lead all worked great including micro wave ,then I noticed the wrong polarity warning light was illuminated on the sargent fuse board ,so I tested the 240 volt sockets on the ecoflow with a plug in mains tester ,that came up wrong polarity reading ,showing clearly the ecoflow 240 volt output is the wrong polarity for uk mains , can any one explain what is going on

have you checked to see if there is an PE (Earth connected)?
I would use a multimeter and check the voltages between L & N, L & PE and N & PE. Often the testers report reversed polarity when there is no PE.

(Never used an Ecoflow, so can't comment on the specifics of how setup)

Not sure about revers polarity as in eu theirs can be reverse

the fact that in Europe a lead can be reversed is not relevant. An AC supply has a Live and a Neutral and that is how it should be configured no matter where you are. An incorrect supply in Europe is not an excuse.
Also, I don't think the Ecoflow has any kind of pass-through* ability, so what polarity the output is has no bearing on what country you are in.


*I may be wrong on this and the Ecoflow can operate as a UPS type device, but I don't think so.
If it CAN, then maybe the output polarity can be reversed IF the supply is reversed, but that should be the only time. For example, a Victron Multiplus has pass-through and if you tested the output of the Multiplus, its output would be polarity-reversed if the input was also reversed. But as soon as the input power was removed, the multiplus output would flip to the correct polarity.

Known fault on very early models apparently. Was it second hand? If not send it back.

That video looks like applicable to US models only as it talks about only the higher output being reversed. UK ones won't have two types of AC outlet, just the 13A type, I am sure. Could still be swapped over of course and wouldn't be that surprised.
 
Lots of inverters do not have a positive and negative. They send 115V down both wires but out of phase. This means that at the appliance the desired 230V is achieved but each wire is carrying only half the voltage. It is how my Victron inverter works. Perhaps the inverter in the Ecoflow is of this type and it is behaving perfectly normally. If this is the case it will show reverse polarity whichever way the connection is wired. Only in the UK do we get hung up about polarity and that is because we use socket switches and plug fuses that only protect the positive wire.

And .... we are in the UK! so maybe it does matter?
Speaking as someone who was electrocuted (fortunately not fatally ;) ) due to someone incorrectly wiring up an American mini-computer as they didn't understand - or took no care regarding - which wire was hot and which was neutral, I tend to think it is more important than apparently most peoples slap-dash approach.

There are lots of inverters of this type sold in the UK. I even had a British Sterling one which gave you a choice of which way it performed by simply reversing a fuse. They don’t have a socket switch so you can only turn them off by pulling the plug out. Obviously not defending the person who wired the mini computer wrongly but most of the rest of the world simply does not understand our need for polarity. It is basically a UK idea that I think started with our ring mains needing extra fuses and switches for protection. Radial wiring with 2 pole switching doesn’t need polarity in the same way.

This is why I pointed out it was an AMERICAN mini-computer, rack and all, including the PDU. So not only a UK idea at all ....
 
Thanks for replies , I contacted eco flow customer service ,had 2 replies in under 12 hours ,all I had to do was connect 240v charger ( I have never done this as I only used solar ) and the ecofow will automatically change to the correct polarity, , did this and bingo it worked , very impressed with ecoflow customer service

Interesting. The CORRECT Polarity? Or the same polarity as the charger? just asking/clarifying that point as probably means if you plug in the charger on an supply with a reversed polarity, it will switch back to being wrong on inverter use afterwards. likely something to be aware off....
 
The same polarity as as the 240 mains used by the charger the polarity has changed on my ecoflow as this is shown on re test with my plug in tester so confident it is good to go , I will use my ecoflow in my van in the next couple of days .so will report if my Sargent warning light is out in a couple of days .
My only disappointment with eco flow is the lack of information in the Manuel's and on line Manuel's .
 
Eco flow has a built-in charger so it resets to polarity that mains charging cable is plugged into IE uk or Europe ..
 
So we have a power bank with a polarity that can't be predicted unless you charged it yourself. A nightmare for some I would imagine 😀. But I should imagine most use them for 12v DC only.
 
I have a Bluetti power bank which I use at home mostly for the 230V output and it doesn’t matter one jot to me what the polarity it is. Why would it?

Toaster is off because it's popped right? No danger?

If the polarity is wrong, it could still be live.

Etc. Things that only switch the live will maybe have a dangerous voltage on them.

Maybe not a problem, but that's why you should care.

And very good we do so, i dont want to handle a live kettle frame etc, nuteral is in fact same as an earth, only the live wire will kill you if you are earthed to ground. :eek:

Definitely not the whole point iof a power staion is to give you 240 volts in the van but all in one box , I use mine for electric kettle toaster micro wave as well as charging all the toys it has an 1800 w inverta so powers almost anything ,and is topped up by portable solar in our wonderful British sunshine ,and is useful at home to cut down on electric use and power cuts
 
I can see that a 1800w inverter would be useful but I assumed that most are 750/1kw and lower and used in tents for lights,cool boxes and DC charging. Although I can't use a kettle or microwave a 600w inverter off the leisure batteries gives me what I need in the van.
