I've heard good things about simtek.

No personal experience. But Homage etc is crap.

You want theoretical answer or empirical ?

Theoratically it may seem like on paper inverter without transformer is good in saving. Or bad desi made silver winding really takes electricity a lot.

Empirically, my desi made copper wiring takes less electricity to convert, ( I’ll ask further) and doesnt overcharge.

U were too late to reply after researching alot and through practical UPS making guys advice bought SIMTEK pure sine wave XL-1000

Post pictures of your setup.

A.O.A

Hope everyone is doing well! I am interested in 5-6kw solar system with net-metering for my home in Lahore. what would be the estimated cost and which company is best in terms of product quality, price and after sale service. i am planning to get it installed in next 1 week. Beside what things i should keep i mind? any new solar panel etc etc in market.

Regards

WS. Approximately 100k per kilo watt. For net metering system better go with 7KW at least. Buy 10KW inverter instead of 5KW as price difference is not much. Solis, Goodwe or Huawei depends upon your budget. Better go with 500W plus panels but 440W mono perc panels atleast. Prefer bifacial panels.

Hi dears. Is there anyone in this forum who has experience to share about infinisolar hybrid inverter. I want to upgrade my old axpert inverter with infini.. all this will be DIY..most vendors say their product is best whether they have VM2 or VM3 or infini..but I need user review so that I can buy new inverter which has better users reviews

umans (umans) 2021-05-10 01:22:45 +0500 #2872

I don't have 1st hand experience but as per my findings, voltronic inverter takes 1/10th of load from utility even if generation is sufficient. To me they seems like old tech, fan based cooling, still stuck with basic lcd, requires maintenance.
Go for Nitrox or Onyx (originally deye hybrid inverter), 25 years designed life,IP65 so maintainance free, dual mppt and more efficient snd many other advanced features.

nawan885 (nawan885) 2021-05-10 11:19:57 +0500 #2873

Do you think Nitrox 3.6 is a better option. Is there any person using 3.6kva nitrox here

umans (umans) 2021-05-10 12:35:02 +0500 #2874

No, go for 5KW at least. Other than Nitrox, Tesla HLE 5KW is also a good option in my opinion.

nawan885 (nawan885) 2021-05-11 18:58:49 +0500 #2875

Actually net metering is not available on single phase inverter across Pakistan and not available in AJK even on 3phase inverter.. secondly I am using 3kv 24 inverter by tesla for 6years and my requirements is being fulfilled except for one thing that old inverter don't mix solar and wapda to supply required load so in evening solar is being wasted so that s why my update will be 3kv to save batteries expenditure as old batteries will be used.. nitrox is expensive and my option is either VM2 or infinisolar 3kw 24volt inverter both can support 4000 watts PV so even if we put 2500 watts load on inverter it will be generated from 4000watt PV

umans (umans) 2021-05-11 19:33:54 +0500 #2876

You are thinking in right direction. Any VM2 will do. Infini v2 will be little costly due to net metering option.
BTW in Punjab & KP, net metering on single phase inverter is allowed upto 5KW

I finalised 20 solar plates of longi 540 & 15kw inverter net metering without batteries. Now I hear that during daytime if there is loadshedding I will have no electricity from solar panels.
Please guide how to avoid this situation.

umans (umans) 2021-06-15 00:29:04 +0500 #2878

I'll recommend you to go with 15kW on grid inverter and 5KW off grid
Direct one string to off grid during loading shedding.

highroller (highroller) 2021-06-15 00:34:21 +0500 #2879

Can same set of panels on one string be redirected to off grid inverter on need basis with some kinda changeover?

umans (umans) 2021-06-15 00:41:21 +0500 #2880

Well DC auto change over are not available here but you can improvise with two DC circuit breakers. Buy a DB (pic attached) which allows only one breaker on at a time. In outage, just manually switch off Grid tied breaker and switch on off grid breaker
