Yeah I thought so too that RCCB and RCD are similar terms..

Thanks for your input. I think some electric geysers come with ELCB in Pakistan which requires a ground.

Do you know how to verify if it is RCCB or ELCB?

Eg I’ve seen this one with geysers https://m.youtube.com/watch?v=9n2d4ALe1hs

Thanks

Solar experts,
Needs your views on this solar setup. idea is to share solar panels string between ongrid and off grid inverters using switch.
will this work ? any down side ?
Offgrid is small inverter and it can not handle full PV string voltages that is why spilt is required.

Regards,

rates revised downwards now

[mrdeejay]

What are the new rates? Any confirmation regarding news about Sales tax implementation on solar panels?

[ifadey]

Good for public but government is not happy with this

How's solar systems doing now days guys. In Lahore we have no sun for past 4-6 weeks and 2-3 hrs of load shedding every day. My 15KW on-grid is only generating 10-20 units a day. This month's total generation so far is only 300 units.

[centos]

Bhai growatt se to dooooooor hy raho. Family friend ne liya 15KW or ro reha jab se liya. It used to trip at peak generation times and now yesterday it's firmware updated and now it has become a 3KW inverter. lol

I have goodwe 15KW working fine for last 2 years.

Shukriya bhai kisi ache installer ka bhi bata dein plz mesol se panels le lon

[centos]

I got the whole setup from Pantera energy. They took care of everything.

hello fellow members @mgalaxy3 @centos @mrdeejay @abbasjin @nfssaad
is there any reliable system integrator in Karachi who can connect and energise the system. All sundry items will be provided by user as per list. please advise what is ongoing service charges for system integration & energising (ITC aka Installation Testing & Commissioning). Request please share number of the person so we can negotiate. we have fabricator. pv supplier & inverters lined up 8 kw x 2 systems are planned.

AoA bros, Kindly help me regarding this issue:

@Hassan1991 bro I need your help regarding this issue. My growatt inverter has uneven spikes. Some say it's due to clouds, others say it might be due to a grid problem. The error during those low spikes is 304 (grid frequency outrange). The inverter has some setting about it and the default freq. is 49.5 low and 50.2 high. So I was thinking about this: Can I change the frequency a bit, like 49.00 to 52.00, so that the frequency fluctuation may not halt the inverter performance. Is it safe t…

Will this be an offgrid setup only with no net metering?

[sardarg]

yes sir @akbargr8 it is hybrid system without net metering.
for net metering in KE jurisdictions, minimum of the 2 utility bills ( ssgc / kwsb) for 6 months or older be in the name of owner., as per govt papers.

[AkbarGr8]

Yes and needs 3 phase inverter / connection to qualify for net metering.
