Hi Roland, ich hoffe das Dir der Hersteller mehr INFO gibt ! Ich habe das bei einem anderen Fabrikat versucht....keine Schematik nichts.So warte ich auf einen Inversor welcher gleichen Typs ist und mir angeboten wird. Aber zum Thema: HUT AB für Deine Arbeit, Geduld und das Teilen hier bei UA-cam. Beim nächsten Mal mehr Erfolg Wir lernen alle davon ,auch gerade wenn es schwierig wird. Gruß aus der Karibik
Roland, here are some quotes from a website I found (related to SUN 1000GTIL2 suffering a catastrophic failure after a surge): "3.3Vdc supply is shorted and this powers the PIC (U11) responsible for controlling the power inverter section. Unfortunately, the PIC was also shorted along with U10 (see main board). The PIC holds the source code that produces the control signal to operate the power inverter section." "The (initial) culprits: driver mosfet IC, IGBT transistor, resistors (050), 12volts IC low voltage side (located underneath (or bottom) the main controller board. After replacing all of these I found out that the PIC controller (shown in the photo) was shorted - pulling +3.3v to GND. The PIC is not something you could replace because this holds the software in managing the ENERGY / POWER production. Replacing the entire board is the only solution."
Great introduction at start of video. Everyone loves a boom. Expect the other sort of fixed inverter to go bang too, since they share similar symptoms of not ramping up to full power output.
Hey! There is this fellow from Der Kanal, in Germany, maybe you should ask him for an opinion. I had one of those inverters, after two years few MOsfets from DC part got burned, I successfully replace them and works again. I was lucky, probably.
Hi. I was watching your video :) Yes, DC side is easily repairable compared to the AC side. The AC side mostly leads into a problem with the AC measurement circuit and the MCU there. The PIC MCU is only 3,3V tolerant on any of its pins, so if you get a surge it seems to kill the MCU quite quickly. I do communicate with Christian, but for this case he didn't have success as well. Thanks for the hint. Greetings!
Time and time again lightening strikes leave electronic equipment unrepairable it just goes from one thing to another it seems. You gave it a great try but I would not have the patience to try that long. Maybe find some used Enphase micro inverters to replace them lol.
You have experience with micro inverters running from batteries. Is this working without problems? The only thing is that I do not know if then can as well be set to zero export.
Yes I have used 3 250 watt Enphase with batteries you just have to have the voltage dialed in to the specs of the micro inverter but it is all or nothing and the way I had it hooked up it fed back through the Magnasine 4024 inverter to charge the battery so the only control was the Magnasine would raise the hertz when it wanted the charging to stop as it had nowhere else to go if the grid was down. I did buy an AC controlled 50 amp breaker from Sigineer which could shut it down when any of the controls (hz, volts, amps) were exceeded but I never went through with it as I found the Sun inverters were easier to install and I had more control.

Roland, apparently another UA-cam user has had a similar problem, where a MOSET had blown up after repairing (same model inverter as yours in this video). The issue seems to be related to the poor quality thermal pads under and on top of the heatsink (that sits between the rows of MOSFETs) not being efficient in transferring the heat away from the components towards the case. The solution was to replace the poor quality thermal pads (as they can not be reused once removed) for silicone thermal pads. It also makes sense that the AC (Wattage) Output would be crippled (limited) by a thermal sensor or resistance caused by a lack of inadequate thermal conduction that removes heat away from the MOSFET area to the heatsink and then to the case itself.

@@RolandW_DIYEnergyandMore I would save up a bit more, and go for a 3 phase unit straight up.. I know it is expensive, but it should fix a lot of your headache and be much more reliable
@@houseofancients yes. Only a 3-phase unit can do what needs to be done here. I think that the powerwall will need more then an inverter change at some point anyways. I guess there will be the right time to swap out the old crappy cells and then fix all up at once.
@@RolandW_DIYEnergyandMore well cells can still provide power, and you have plenty of them :) And again replacing the batteries at one point would make for a nice new video series ;)

thx, yes. my conclusion is too that the PIC MCU is damaged in this case too

Yeah. I really do not like Ac-Side faults on this inverters...

@@RolandW_DIYEnergyandMore Good luck and all the best!
@@RolandW_DIYEnergyandMore You just trigger and idea, maybe 3.3V from an external power supply , before anything will keep the things safe...?
Don't give up on it just yet see if you can get more info from the manufacturer
Yeah. I will.

Also I had two separate battery systems one for the Enphase inverters and one for the Magnasine.

So sorry you repairs failed Roland....
Still see a new deye in your future I'm afraid
haha. i am afraidyou are right

Can I mail mine to you?
what is the issue with your inverter? Where are you from? The probability of a fix is ranging from 0% (AC-side) up to 100% (DC, others)...
