Solar System for 1 DC inverter AC

[waqasne]

1. Yes, you can say that. All of wiring diagrams are available on the internet and user manuals, you can always refer to them

2a. I disagree, in case of grid fluctuation , the inverter should sense the grid is unstable and switch over to battery power. If you get a good branded inverter (not China knockoffs), it should not be a problem.

2b. I am not a huge fan of axpert inverter, they are like desi UPS with in built solar chargers. They have terrible power factor, noisy and constantly rely on batteries. Instead i recommend you buy an external solar charger and connect solar panels to your battery in your current UPS. You would end up doing the same thing.

2c. However, if your area has a lot of load shedding in the day, getting a hybrid inverter makes no sense. then consider axpert.

1. When I used to reprogram inverters to stop grid feed in , I did not find any power going into grid. Can you share the links where you found this information ? As per my observation, shop keepers dont know how to stop grid feed in, so they end up saying its a stupid inverter

answer to your last question regarding
1) Refer to the user manual for connections
2) When load is greater than PV input , it will switch to grid power. If grid power is not avaliable, it will consume battery. When the battery DoD level is reached, the inverter will turn off. So inshort, the PV power always has to be greater than load. This is why i prefer hybrid inverters

a small summary

@waqasne bhai, Really you are very helpful. I understand each and every point that you told, In few days, my system will be ready In Sha Allah, I will update this thread with my system specification

May Allah bless you

Thank you

[waqasne]

I am glad i was of help, please make dua for me.

I look forward to your system , goodluck

Ok. Thanks for your input. I will follow your recommendation and get an infini hybrid inverter.

Can you share feedback/info on hybrid solar set-ups you've installed?

[waqasne]

I worked until 2015 with a private company dealing in solar solutions, I then left for further studies abroad

I can however get you in touch with my colleagues

@waqasne

Can we use infini without the batteries. I want to run my load on solar during the day. At night I am happy to be at the mercy of LESCO. I will invest in good 2V cells later.

So just a 3KW infini plus and some panels to provide minimum 1kW during the day. I will add more panels to saturate the inverter later.

So, is this possible ?

[Khurramchauhdary]

Imo yes but it won't fulfil your need without batteries. It will run the load(fans) on very low speed most of the time.

[waqasne]

I never tried to run infini without the batteries, I reckon you can NOT do that. I remember the main source for the inverter is battery (it turns on using the battery), I never removed (nor recommended) to remove battery connection while operation.

I recommend you refer to the manual, PERHAPS (not sure) you can program the inverter to use grid as primary source solar as secondary. The inverter will always use grid as primary and (when avaliable) use/combine solar,

1st Pv ->2ndGrid

and

1st Grid

If you can , please invest in 2V batteries, these banks can easily power your house at night and are long life.

However you will have to increase the solar panels so that batteries are charged using the solar power only, refer to post number 16.

What's the price of Infini 3kW and 5kW hybrid inverter? Any inverter better (or equivalent to) than Infini in the market?

[Khurramchauhdary]

I need to be clarified that every one here is talking about infini plus inverter... my question is if infini plus is a Brand or its a technology which offered by all brands i.e i have to buy a Homage infini invertor or Hicell infini plus or its only infini plus? yester day i went to a shop asked him about the infini plus but he showed me Hicell Infini plus and told me that its not a brand it a technology so please let me know i should buy that or remain in search of Infini brand coz i had seen infini brand on the inverter.

[Sdogar]

I am a noob in solar thing. have few questions:
1. What is the expected life of solar panels?
2. Is it justified to get solar panel setup over generator? What are the advantages and disadvantages ?

[waqasne]

From China, you can order inverters with no brand name on them. Later you can get customized names printed on them . Just like Suzuki released the all new Cultus but its called celerio in the international market

[waqasne]

You have to research, I am not aware of market

[waqasne]

Google yours questions , you will get the answers

[Khurramchauhdary]

I asked if infini plus is a brand name or technology?

[mharoon.mriaz]

I do not have great knowledge, but here is what I know

Bhai there is a company named "Voltronic Power" , all famous brands in Pakistan like inverex, tesla etc place order to Voltronic for inverter. Infini is assembled/manufactured by voltronic and sold to other companies.so there will be 2 logos on inverter, one of voltronic and other of local company (according to mu information, not confirmed)

Infini is a model of Voltronic, same as Nokia is a company name and asha is model/series, or we can say that Samsung a company and j7 is model.

[mharoon.mriaz]

1. depends on quality of panels, good quality panels life is upto 25 years.
2. both have advantages and disadvantages, please search on google, there are a lot of articles about this

[Khurramchauhdary]

But I was offered an infini plus 5kw inverter of Hicell company. What was that? That was marked as infini and HICELL.

[waqasne]

brand name , different companies are importing and putting their logos on it.
