Thank you so much for the information

@schneiderelectric 3 года назад

Thank you for your feedback!

Very well explained, thanks

Please explain more details about power factor and hybrid in double conversion technology inverter…thank you

@manjyotb 4 года назад

How do I implement this? Ever since I've installed a schneider solar inverter my PF loss is more than the generation gain.

@schneiderelectric 3 года назад

It is difficult to provide an answer for specific cases without knowing the context. For your concrete case - please contact your local Schneider Electric Support Center.

@electricalsolargyan6157 4 года назад

Dear Madam as per your solution there is loss for installation and investor company in solar PV plant . I have one more solution , as we know that we are using APFC Controller for supplying reactive var but due to reason because APFC get sum of solar and grid that's why not able to measured only grid . If we Install CT of APFC panel In main incomer of grid line and then operate Capacitor duty contactor though it then you will be able to supply Var for reactive power demand . in this way you will utilise full solar power for active power . because if we supply reactive power from inverter then there is decreasement in active power of inverter which is finally a loss of inverter power

@akshay3348 4 года назад

Ranjit your solution is partially correct, what if only solar produced kWh are being utilised by the industry for certain time of day? As your sensing is of Mains, the APFC will remain there as mere statue.

@schneiderelectric 3 года назад

Hello Ranjit! You are right, dedicated PF equipment to correct PF loss is a good alternative solution.

@jakovbilic4556 2 года назад

I would like to know more about this, do you maybe have some drawings of this kind of systems. Also how would you connect smart-meters and what would you really get from grid if you produce 100% of active power you need?

@niaziexplores 3 года назад

Do modern inverters have built in controller or set points to control their power factor?

@schneiderelectric 3 года назад

Hi Niazi, thank you for reaching out! A built-in controller inside each inverter would probably not be the most appropriate solution, as usually one installation contains several photovoltaic inverters. As we see it, it's better to have a control system (transverse to the complete installation) which gets measures from the different photovoltaic inverters, and gets the value of the power factor at site level (at the point of common coupling). Based on this data, this control system determines and communicates the optimal set point to each of the photovoltaic inverters.

What can be the other effects of PV system for reduction of Power factor and how can we improve pf within photovoltaic system?

What about power quality and power factor when the excess amount is exported to grid? I mean in Mains revenue meter what will be the PF ( inductive /capacitive) at the time of export?

Kindly confirm that will capacitor bank panel also work along this control system? because it will be better to get more KVAR from capacitor bank either from the inverter.

@deepalps 2 года назад

did u get some solution, I am facing the same problem.........where to place the CT with integrated systems of PV solar and utility. our system consumes 300KVA and solar panels provide only 200KW , the pf goes down specially when our utility is not consuming power

@engr.sohailtariq6261 3 года назад

Kindly confirm that will capacitor bank panel also work along this control system? because it will be better to get more KVAR from capacitor bank either from the inverter. Like if we have 150 KVAR Load along with 10KVAR fluctuating KVAR. We set the setting like 120 kVAR should be adjusted by capacitor bank panel and remaining divide it on inverter and grid line w.r.t real load.

Thanks for your question, Sohail. - Our expert is on leave and will answer back as soon as possible, when back to the office. If your question is urgent, you may try to contact your local Schneider Electric support: www.se.com/ww/en/work/support/country-selector/contact-us.jsp

@schneiderelectric 3 года назад

Hi Sohail, thank you very much for your patience! - The solution we describe in the video is suitable only to compensate the power factor impact of the PV system. When it is necessary to compensate the reactive power of the loads, capacitor banks are the suitable solution. And if the reactive consumption of the loads is highly fluctuating as you describe, automatic or dynamic compensation will be recommended.

@Gallardo6669 25 дней назад

It doesn't click in my head: i understand reactive power is undesired. Therefore its always better if we reduce the reactive power within the whole grid, not only at the measured interconnection. Therefore injecting pure active solar power into the grid should benefit the overall ratio and reduce the percentage of reactive power within the grid. Pls Internet respond...😂
