Inverter not recognizing generator

Provide more info and pics of your setup.

we have 6 x 300w panels - 5kw inverter - 8 x 100 AH batteries, it's been working for the last 2 years with a generator, then suddenly not accepting it, will send photo's later, not sure what photo's i might need ?

A. It's an electrical problem. What path does the electricity take on It's way?

Have you verified power at the input of the device?

It could be anything from a bad cord to failed device. Without any info it's difficult to offer suggestions on what and how to go about checking stuff.

There are thousands of different kinds of inverter/chargers. Without knowing what kind you have, were just as in the dark as you are. What does the owners manual say a flashing Gen icon is indicative of?

I assume you mean what path does the electricity take, it's a wire from the generator to the inverter, it's a hybrid inverter does that help ? We have tries a different generator, still the same thing, the manual doesn't say anything about a flashing light, i've asked the company where we bought it, they say don't open the inverter because it will void the warranty, they say the voltage is coming in too high, but we don't know how to change that, they say a setting has been changed, except we haven't changed anything, it just started to happen, they also say check the manual to see how to do it, we have been through the book from front to back, nowhere does it say anything apart from refer to to customer services hummmm

HYBRID INVERTER 5KVA 48V PWM 50A-ECOWATT

Ok. So the first thing you do is verify correct voltage at the input on the device. This means putting a voltmeter at the terminals on the device where the wires from the generator attach. 

If that voltage is within spec and you have way to adjust anything or do anything, unless someone on here has actually seen and dealt with your setup, then you are out of luck. 

Judging by it's price, age and level of support you have received, I would guess the unit has failed. Sorry I can't be of more help but you need someone with a higher level of skill to look at it for you.

Ok thank you for your advice, got another question, this might sound silly, but with the voltmeter which setting do i put it on ?
I think the company realize it's the unit and don't want to honor the warranty !!! 

The setting that has the symbol that looks like this: ~  It might say "A/C". The DC setting would have a dash underlined with a bunch of small dashes or say "DC".

You want the A/C setting. 

I would take the unit out and then just hook the gen directly to the cabin and enjoy it that way for the rest of the winter. Unless your generator is huge and loud and gobbles fuel? This would be a good opportunity to buy an inverter generator if you don't already have one. I am a fan of them as they help you keep trucking when you get into the situation like you are in.  When our cheapo stuff fails and leaves us hanging, we can break out our little honda or yamaha generator and keep fishing or camping or skiiing or whatever it is we are doing at our cabins for the remainder of the season and take the stuff to fix, troubleshoot or recycle at home where we have the tools, resources and time to do so.

We are doing it direct to the house, but very expensive, ok if we get some sun, but that seem few and far between at the moment, we were wondering if it's the printed circuit that goes to the connection where the generator attaches, we only know that exists because we have another one, that we can compare, we only haven't changed it because of the warranty, but after we've checked the a/c, think thank might be on the cards, because since i've asked the manufacturers to be more specific 'no reply'  what a surprise !!!! going to try the light bulb thing as a previous person suggested.. it's not a cabin it's our home, so really important, bloody China !!!

Oh gotcha. Well now is a good opportunity to buy a victron multiplus.

I have no experience with them personally but they have a good reputation and it's a nice unit that is perfect for your needs. They are $1200.00 vs $500.00 for what you have but the reliability will be worth it.
