huawei 15kw 310-320kgoodwe 15kw, growatt 15kw, SAJ 15kw, solis 15kw, sungrow 15kw, all are in +- 250k rangemy recommendation, in budget, go for huawei
I need help! @Hassan1991
Can someone tell me from were can i remade the wiring of self motor of my 3kva generator?
Current status:
It can be re winded.Or try to find brand new similar armature.
What's the actual output in kWh of 15kw solar system in Lahore in %. Is it 80% efficiency or closer to 70%?
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)
Ok...
What is better? To buy new one or rewind it?
And what would be the estimated cost?
@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.
Ok. Thanks...
And sorry for irrelevant discussion i thought it is relevant to Generators so i posted it here...
annual output, you can expect approx 21MWh (+- 20-22MWh depending upon weather, load shedding etc)
Thank you.

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.
It is normal. Vmp mentioned is for Standard testing conditions.
Yes, the rated Vmp is for 25C. It gets low with higher temperature so 38 is fine for july. In winter or where it gets cold voltage goes above the rated Vmp.
the video shared above is direct contradiction of bi-facial panel efficiency
Today it was windy and cloudy with bit of rain. The temperature was low so the voltage range for the same string today was higher 580-590v.
Salaam - any one here using a 3 phase on-grid inverter and 1 phase hybrid inverter simultaneously? Thank you!
such setups are rare., but yes can be doneanother setup, but it has both 3 phase inverters, growatt and nitrox
Awesome - thanks for sharing. I'm looking to add a hybrid inverter to my existing ongrid huawei inverter but my installer tells me that it is not possible. Claims this is due to huwaei / hybrid inverter being 1 phase. My idea was that the hybrid inverter should also export excess units when possible.
Still researching this but thanks for your input.
can you share all details, your inverters, and panels, and what's your primary aim behind this? generally, hybrid inverters alongside on-grid inverters are used for backup during load shedding
