Wow Graham I have met my match ! That was a long one lol !
Yea I did a bit of over here in wa, it use to be called TAFE.
I did refrigeration, aircon, domestic appliances, electrical principals.
But that was a few years ago now,2004 long story but didn't end up doing much of it myself ! So as you & the guys would know, if you don't keep up with things after you have learnt it, well it don't take long to forget most of what you did learn ! & that's me !
I have brains enuf to know don't play with something you really don't understand m8t !
That's why I took it someone to have him & his mate look at it.
But I am not certain if they actually know or knew much about inverters, they had it for 8 weeks & told me what I basically knew. They had lots of tele,amps, radio equipment around, in a games room setup
I just didn't know what part or parts were dead, all I know is its in the motherboard, he did say it was unusual that it shorted out there, they generally short out, on what ever it is at the back of the inverter, big square thing with heaps of post, legs or terminals, or whatever its called, got me beat ! Like an aluminium block.
So yes its well out of my field & I won't play with it ! Etheir kill myself or blow it sky high mate !
I live south of Perth in Myalup Harvey 6220 postcode, roughly 90 mins from Perth.
Mosfets, I don't even know what that is Graham, this is well & ,truely out of my understanding ! Just need someone to fix it, not so many people over here get into it, more into trying to get me to throw it & buy one of theirs instead m8t !
I believe better the devil you know than the one you dont I say !
I'd rather throw money into this & up grade, it to something worth while ! Befote I brought it I did some research & it was all positive ! About the powerstar ! Value for monie !
I am smart enuf to know that even a $8000 inverter or tele may have issues, thats life !
The nite it blew there was huge thunderstorm I mean massive at that, its not grid connected, its isolated. Has earth wire from back of unit to ground stake just outside shed door. No lighting strikes anywhere, first thing that I looked for when it was off.
I removed cover looked for burn or short out marks, didn't notice any, then while unit was off no power supply at all !!! Remove a small plug the smallest of the lot that has 4 wires on it, from motherboard or the smallest board & it then started surppling power to the house again ! But from generator only, will not supply power from my battery bank at all, to house or shed The LCD screen don't display anything, not even light up M8t
Generator was off & inverter was just running off 24 volt setup. 12 Emerson T 2vlts 500amps each.
There were a few times over a month or so, I would go out to shut the gen down & the LCD screen was reading, it had lost communication ! So I would turn it off & it started doing what evet it was meant to be doing, but while in no communication mode, it was still surppling power to house, so what lost communication meant I don't know ? But did it at lease 6 times in a month or so !
Yes still still working on photos, look it up last nite, Seems I have to transfer from my ph to my lap top & do down sizing there, more stuff I am not sure about ! But I will get there !
Wow !! That was long winded hey Graham !
