Thanks a lot Capleaker, i have installed 35V 1000uF and it works fine !!!!

Your help was fantastic !!...

Thanks

I will wait to install the capacitors.

57 means "current sensor failed" , based on that what i read, it could be a lot things link to the DC.

Thanks a lot for your advice, i m going to order theses capacitors. Maybe in the delay, i will find a better picture pictures of the pcb sent by an inverter owner.

The inverter is able to turn on with an error (code 57), do you think, it will be useful to mesure the voltage ( voltmeter, small oscilloscope) on missing capacitors termination ?

thanks...

Hello,

Which one would you advice ?

Hello,

Theses pictures were taken before the shop
thanks...

Hello

Here 2 pictures of my PCB, one face and the opposite face, you see the missing capacitor footprint , and the capacity of capacitor arround, a tension regulator component 78M05.

Dear,

I thought the inverter had failed due to a battery issue, so I sent it to a repair shop.

They gave me a repair quote for 50% of the inverter's value, which I refused. When they returned the unit, I didn't check it right away. A month later, I opened it and found that two capacitors were missing.

I am certain they were removed by the repair shop since i took pictures of the motherboard before to give it.

I finally found a issue on the battery circuit breaker in my installation, so i think the inverter was working fine

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...
