💯

[@NoLandMan001]

Any english explaination please. What is a root caust and how to recovery?

[@m0hd_]

Moisture, bad mc4, cutted cables

Thanks you do much 🙏

Where should be minimum folating voltage of healthy Dc String ....

[@solarfacts4242]

No floating voltage

Sir mere samne problem aa rhi iso fault। P to N 360v
P to E 360v fix
N to E 0v aa rha hai to kya problem ho sakti hai please suggest

[@solarfacts4242]

Negative wire me kahi cut hai

[@rameshgaurikar8284]

Sir,mere growatt Inverter 6kw me "PV Isolation Low" kya same problem hai kya yahi?

[@mastersolarenergy]

I same problem.
Growwat be inverter 5kw. Single phase.

[@rameshgaurikar8284]

@@mastersolarenergy Solution Given by Growatt 2 me-
Solution-
pv isolation low is because of DC side strings isolation issue .,if string connectors are not tighten well & not taped completely then water can ingress into it causing low isolation, so in this case inverter will only show the current low isolation status.
So plz turn off inverter recrimp all mc4 connectors from series and tape it well to avoid any leakage & make sure all string +ve & -ve to ground vtg decreases gradually then pv iso low can be troubleshoot from root.

[@solarfacts4242]

There is problem with positive or negative wire of string

[@shreyaelectrical4961]

Thank you sir very useful video

[@solarfacts4242]

thanks

[@vishalunawane6155]

thanks Sir

[@solarfacts4242]

Thanks 🙏

[@ravikumarsharma5404]

Sir if negative wire having isolation fault than i check it it's show 0 and positive wire show full string voltages

[@solarfacts4242]

It means there is problem in extended wire

[@MuhammadUsman-xn7fh]

thanks you video. could u pls define, isolation fault or PV abnormal fault is same??

[@solarfacts4242]

no both are different

[@MuhammadUsman-xn7fh]

fine thanks. so pls upload a video of PV abnormal fault. this fault occure when nay MC4 open or short. pls define how to identify this fault.

[@siddharthsrinet9022]

Bhai ek vedio solar optimizer ka bhi vedio dalo plzzz 🙏🙏🙏

[@solarfacts4242]

Hi give me your WhatsApp’s number

[@AmitKumar-qz2us]

What if all string wire in physically good condition but still,found some stable voltage PG/NG ....

[@solarfacts4242]

Not possible

[@sahibjotsinghluthra4389]

hello sir
mere ko bi yahi problem a rahi ha
mere system mein 6 string hai
6 string ki voltage 670 hai
positve to earth grounding voltage 570 stable
negative to earth grounding 120 hai
invertor mein dc inject show kar reha hai
but i cant understand how to solve the fault

[@solarfacts4242]

Jo bhi string me aa raha hai you can find the fault and this fails is in between module

[@sagarsanap5519]

Thanks you brother for amazing video.plz make more such videos.i want to ask you is there any permanent solution for isolation fault. Moisture se isolation na aaye iske liye permanent solution hai kya

[@solarfacts4242]

you should use best quality of connector and connectors should be properly tight

[@johandepauw5969]

Can we have English speech please?

[@solarfacts4242]

Ok

[@zainmoin2457]

Apna no share kar dain

[@norbertnox6887]

You start in English then switch to Hindi, not good. Stop then also using English title to deceive people to have views
Not understandable for others

[@benson7600]

hanep na yan Hindi ko maintindihan.

[@solarfacts4242]

did not get you

[@ketanagrawal8940]

Sir what is your experience of isolation fault on 100 kw inverter of Chinese make inverter like Solis, Huawei and sungrow.
We have noticed that Solis inverter is completely fail in case of ground fault.
Do you come across such incident where inverter did not trip against the ground fault and completely failed even after all string voltages are healthy.
Please give your contact number to discuss this with in details.

[@solarfacts4242]

Ground fault protection is very important and I will tell in all Inveter this feature is available
If this is not available then there is a risk of electric shock to human body
