Inverter Type AC in Pakistan (Inverter/Non Inverter Dedicated Discussion)

[qwertypoiu]

@whiteangel Since you are using solar and can explain in easy words here's are few questions

what do you run on solar? everything which is wired for ups or something extra? Explain how its wired...

If one has 2 2kv Apc ups(total 4kv) How will one wire it? How much watts solar panals will one need and inverter? secondly if excess solar power is generated how will one stop it from going in wapda grid(since we will still be charged$4)
I believe in your idea to use solar directly in day and wapda at night and few batteries for backup

Infi by voltronic is the highest selling hybrid available in the market...There are two types of infini available i.e. infi and infi plus... the difference is that simple infini supports 3200 watts from PV and infini plus supports 4500. output for both is 3000 watts.. but never ever ever ever use it over 2700 watts at max... which model is yours???

Chinese brands are not designed for the full load... even the manufacturer or the retailers suggest it... it will simply decrease the life of the unit or it will start giving trouble... over the time i have learned that till u use and not abuse a product you will be fine and the day you start doing otherwise then you are asking for trouble...
having said that you also need to calculate the ampere range that you are going to put on the unit vs that is allowed via it. i know a person who was using a 1.5 inverter split + a desert cooler+ 5 fans + a dozen lights + LED + fridge + Freezer on infini.. one fine day everything was presumably "ON" at a given time and thus the unit failed... thank god he had a ampere (if i am not mistaken 15 amp) breaker installed as a safety... the unit thus survived the scare
moral of the long post: bro you have invested quite a lot of money... but dont become greedy.. respect the unit and it will respect you.. and if possible and your vendor is known to you then please switch to infini plus... you will not regret it

Sir i have recently installed 1.5 tons gree a/c with round display they are amazing my room size is 14 feet by 20 feet. ihad general window type a/c installed before them .....i can tell you that all 4 family members agree that gree is out performing even general a/c may be this is due to direction of air which is directly on bed now......i have these two a/c in two rooms the rooms are on ground floor with no direct sun light but still i am loving the cooling and specially the throw of Gree...Gree has one of best fan throw among cheaper brands ............i have no idea regrading electricity consumption..........

You are right as far as cooling in concerned but worst in power consumption

After much research into solar power, I was ready to make the jump to solar, but due to financial constraints I had to put it off until next season.

Anyway coming to your question, You can run anything on Solar, as long as you have the required number of watts coming from your panels and your inverter is of enough wattage. But yes, the first step would be to shift everything on UPS to solar. Since you have already done the wiring, you don't need to do any additional wiring. The only wiring required is the one coming from solar panels to MPPT charge controller and Inverter. After doing this, all you need is to plug everything that was on UPS into the inverter and you're done. The batteries connect directly to the inverter or MPPT charge controller depending on the type of setup you have.

Regarding preventing excess solar power from going back to grid. If you are using a Hybrid inverter such as Infini, this is quite easy to configure in the settings. If you are not using a hybrid inverter and you have wired the system properly, solar energy will not flow back to the grid. Because only the loads will be connected to solar and you will switch manually to solar in the day, switch back to wapda in the evening. For the 4KW APC (I am assuming it is 4KW and not 4KVA). You are talking about 4000 Watt load. You need to size the panels bigger than you load. You need at least 5000W combined from panels. If you have the budget it is better to invest in a hybrid inverter such as Infini. It also has a built in MPPT charge controller so you don't need to buy it separately. Infini will handle everything automatically, when there is sufficient power on solar, it will run everything on solar, when solar output drops, it will use wapda and solar together to handle the load, when there is no solar or wapda, it will switch to batteries. There is a 5KW Infini on the manufacturer website but it is not available as yet. So you will need a couple of 3KW Infini hybrid inverters. The load will be divided between the two inverters.

And by the way this is a bad time to go solar. The govt just imposed some duties on panels up to 32.5%. I think they will roll it back, but until then, it is better to wait and see how the situation develops.

The size of panels and inverter depends on your load. your inverter should be bigger than the maximum load you put on it and size of panels should be significantly more than the average load.

for example I have 3kva inverter i.e around 2500watt peak load.
I have 1500 watt panels and the maximum I have seen them give is around 1000 watt at around 11-2 pm. Normally they give around 6-800watt.
The load in my house is 3-4 fans lights and 2 lcd tvs and a water cooler and air cooler. average load is around 500-600 watt.

During the peak time solar is generating excess power and battery is full. In the afternoon the battery will start discharging slowly and rest of the energy will be from solar.

My infini is 3kw but panels installed at the moment are 1500 watts

@muhammadmusa and @asifijaz

Hey for how much did you buy the inverter? Is it hybrid?
Wanted to see the price difference between hybrid and non hybrid.

I have different series non hybrid inverter from voltronic it is 3kva and the price was in the between 40 and 50k

[Asifijaz]

ToxicDevil i have installed a Infi Plus model at a cousin's place and the whole things + installation was for 6.6 Lacs...

The best voltronic offgrid available is MKS Plus and that too is designed for 3kw load hence you can safely connect 2600 watt load on it.... the other model MKS is simple wastage of money IMHO and is best avoided.

None of the hybrid inverters or the off grid inverters available from voltronic can be synced with each other hence in case you need to add power then then you will have to switch to an all together new inverter system.

I am currently in the process of finding a bigger hybrid for my home preferably in the range of 5kw if not bigger. There are very few available in the market so the search is still on.

Whiteangel which Inverter have you selected??? your post suggests Infni.. am i correct here??

Brother I have installed 1500 watt panels right now I am planning to buy a 2 tonn inverter ac to run on solar how much more watts should I add to my system ? In easy words what is the consumption in watts of a 2 ton inverter ac

Sent from my GT-I9500 using PW Forums mobile app

[Asifijaz]

I would strongly advice not to do so... i would explain it below
1) You need to first calculate the energy requirements (Watts + Amperes both) of a 2 ton AC.... i am aware that a 1.5 ton inverter based AC by acson consumes around 1850 watts +/- 50... 2 ton i ahve no idea..
2) In your case since you have a simple infini hence it is designed for 3200 watts panels which will roughly give you between 1500 to 2000 watts max during the months of june to August and may be September as well...
3) Now the load that can be put on an inverter is dependent on the power factor and in case of infini you should never go beyong 2550 watts max... if you do once in a while its ok but on a constant basis it will simply decrease the life span of the inverter...

Based on the above 3 points its my humble opinion that infni will not produce that much electricity from solar panels to support a 2 ton AC + lights/fans at your place... solely using it for AC is possible but even then for the peak summer months ur solar system wont support anything over 1500 to max 2000 watts.... in case you do want to use infini for ur home + AC then calculate the load and buy either a 1 ton AC or a 1.5 ton AC... 2 ton AC is a big noo...no way..
If i was you i would have exchanged infini with infini plus (PV support of 4500) if not possible or feasible economically then i would have fed in my infini on the max load of 3200 watts through panels... then i would have bought a 1.5 ton AC + good quality batteries e.g. sacred sun 210 and put those batteries on an external charge controller connected to another set of solar panels at roof (extra 1500 to 2000 watts panels with 20 to 40 amperes charger).. the infini will then be put on settings of solely feeding to the load and that the deficit would be met via the batteries which will be charged via solar system through separate charge controller... Remember that even then the load on the infini should not exceed 2600 watts and with 1.5 ton inverter based AC this gives you a breathing space of roughly 750 watts which is roughly speaking enough for 3 fans + 6 energy savers + LED TV

[MuhammadMusa]

Ok fine. Well another thing ! The maximum watts I am getting nowadys are around 1220 watts from you 1500 watt panels so do you think this efficiency will improve after this hot season ? If yes then upto how much ?

Nowadays the temp has cooled down hence you are getting a decent solar production. This would not have been possible about 2 weeks ago. the efficiency can improve to full 1500 watts but i have seen panels producing close to 105 % of their capacity even hence you can go to 1550 even.

It can be done but you need a dedicated 3KW Infini just to support the 2 ton AC. If it were me, I would go for the ACSON A5WMY25L (cooling only) model. It is 21200 BTU (2 ton is 24000 BTU this one is slightly less than that, its about 1.75 ton). But power consumption is a healthy 2000W. compared to about 1800W for a 1.5 ton inverter. It can be easily managed by the Infini and you will have some spare capacity to run a few fans. And since it is inverter based, the actual power usage will keep decreasing the more the AC runs.

But I guess you will need 3000W panels if you want to get at least 2000W from the inverter. It might be also worthwhile to invest in the Infini 3KW Plus model, it costs slightly more than the Infini 3KW but it can support up to 4500W solar panels.

Brother i might have missed the previous sessions and my requested info can well be already available in this thread.
Can you indicate what cost is incurred on a infini plus solar based system if we want to run a 1.5 tons ac solely on solar for let's say 12 hours daily. What is the estimated life of the system?? Thanks..

You don't really need Infini plus for your load. A simple 3KW Infini will do.

1800W is the max power consumption of a 1.5 ton AC (Inverter based). Get 2800W panels and a 3 KW Infini Inverter.

Total cost
Estimated cost of panel (Rs 75-100) per watt depending on brand

2800W x 100 = 280,000
Infini 3KW = 120,000
Estimated Installation cost= 50,000

Total = 450,000 (might be lower or higher depending on brand of panel and type of mounting structure)

Solar panels are very reliable think 20+ years at 90% efficiency, after that efficiency drops to about 80%
Inverter has a life unfortunately. But there is no way to predict if it will work for 5 years or 10 years or more. But most people using Infini have not had any trouble with it. If you want something more reliable, you could consider a Schneider XW series inverter. Authorized distributor with full support is available in Pakistan. Warranty is 5 years. It is a beast of an inverter the 6000 Watt model can tolerate a surge of 12000 Watts for up to 90 seconds. No Chinese inverter comes close to it in terms of quality. But it is expensive.

BTW this is a bad time to go solar, a few days back govt just imposed a 33% duty on solar panels. Yes you read that right, we are in the middle of a power crisis and this is our govt's way to tackling that.
