Goodwe 10KW 3 phase is available for around 4.5 lacs. I think it can have 15KW of panels.

What are the latest requirement about the inverter for net-metering. Does it have to be 3-phase for systems above 5KW as this document from AEDB suggests. https://www.aedb.org/images/NetmeteringGuidlinesforConsumers.pdf

Does it have to be 3-phase for systems above 5KW as this document from AEDB suggests.

Hey bro, thinking of going with on grid as loadshading is very minimum in my area and can easily pass that time with my ups so that’s not an issue, even with hybrid grid will be cutoff during loadshading and batteries backup will use.
Please recommend me top notch 10kw-15kw as you already mentioned fronius anyother than that in 10 or 12kw catagory?

[saqibhassan95]

anyother than that in 10 or 12kw catagory?

huawei 15kw 310-320k
goodwe 15kw, growatt 15kw, SAJ 15kw, solis 15kw, sungrow 15kw, all are in +- 250k range
my recommendation, in budget, go for huawei

What's the actual output in kWh of 15kw solar system in Lahore in %. Is it 80% efficiency or closer to 70%?

[capsat]

15kw solar system in Lahore

between March 15 to July 15 upto 85% tops. (peak summer)
July to Oct it will be under 70% (monsoon & cloudy weather)
Oct to March it can be anywhere between 40 - 65% tops.(winter short sun light hours & smog)

[helper_learner]

Ok...

What is better? To buy new one or rewind it?

And what would be the estimated cost?

[capsat]

@helper_learner you are derailing a dedicated technical thread with irrelevant item.
this armature can be repaired (rewind) by any motor winding shop or can be purchased from generator scrap market in lines area. rewind cost will be under 1000 equivalent to scrapyard item. make a wise choice.

annual output, you can expect approx 21MWh (+- 20-22MWh depending upon weather, load shedding etc)

Can someone share the string voltages of their system. I want to figure out my string voltages are good or not. 15 540w panels in one string fluctuate between 550-575 volts throughout the day. That is 36-38 volts per panel. Is this ok or low. Rated voltage under load Vmp for this panel is 41.65 and Voc is 49.5.

[umans]

It is normal. Vmp mentioned is for Standard testing conditions.
