Effect of solar grid-feed inverter on one-way digital energy meter
-
Hello,
I need help to find the value of 2 missing capacitors ( C102 and C117) on my Easun SMH-II mainboard (solar hybrid inverter). I circled it in red on the close-up picture. The 2 old capacitors are completely missing, so I have no reference. Does anyone have this board and can tell me the value or make an educated guess based on the location ?
My model is : EASUN SMH-II 7 KW
Mother Board : P/N 18947-002401250250
Maybe the EASUN SMH-II 4.2 KW have the same capacitors
Thank you... -
Hello folks, this is a last ditch effort. I thought I would seek your expertise before giving up.. I have been working on this thing for over 2 months and have gotten nowhere. Here is the issue:
Inverter powers on and immediately red GFI light comes on and inverter will not complete the initialization process.
There is no error code on the screen. I have removed most of the Y capacitors and tested to no avail.
All relays are good.
I replaced the current transducer- same problem. Checked most of the transistors and diodes and all appear good. I wish I could get my hands... -
My parent's solar inverter died after 5 years of good service.
It's a called hybrid inverter:
- It can go with or without batteries
- It has 2 MPPT (8 330W panels in 2 strings) -> 5280Wp
- A 20kWh lithium battery previously used in a Nissan leaf (14S at 4.1V max) -> 57.4V
Panel is showing error 17 and the battery connection has disappeared. On the other hand, is delivering load, MPPTs are working and it's exporting energy to the GRID. Not that "bad".
Let's open it......
I see that 150A fuse is gone and the... -
I just seen this item is this a good idea if why and if not why not
Here is the website link to it

My cheap crappy 1KW grid tie inverter (GTI) seems to keep blowing IGBTs. When I first got it, it had two failed IGBTs. It used four 60N100's (TO264). I bought 5 from a dubious source (fleabay) and replaced just the two that were dead. The GTI worked for almost two years but recently one of the two that I replaced failed. Since I had three spares, I replaced the dead one. Then a few weeks later it failed again. Weird. Well since I bought dubious China-sourced IGBTs from fleabay it could very well just be a mixture of fakes. I replaced it, but then a day later it failed again! I put in the last...Today, 12:34 PM
