The Alternative Energy Thread - Generators, Solar, UPS, Wind

[mgalaxy3]

hey

specially @nfssaad . you've answered me before so hope you can guide me further. Others too welcome !

I want to run under 2-3kw load. Any solar UPS that can give power in this priority:

-When solar available, use that to give output.
-When solar 800w available, but load is 1600w, use full 800w from solar, and remaining 800w from utility.
-When no solar/at night, use UTILITY to give power
-Lastly, when no utility+solar, only then use battery power (to save battery cycles n discharge).
-Use solar to charge batt, if no solar available(at night) then use utility to charge battery.

**Optionally, when I don't have any battery connected, it should be able to output from only solar or solar+utility too... but not required as I will mostly have a battery attached for backup...

Anything not too overpriced?
And what is this mode called in all the power/solar terminologies... ?

[mgalaxy3]

cc @umans too if you can kindly help..

Hybrid solar inverter is the answer. There are many chinese options available. No idea about solar ups.

Can you tell which model satisfies all those requirements, any specific good model name please..

Recommendation for good Hybrid inverters?

[centos]

Goodwe is the best option right now. If that's expensive than onyx and nitrox are good options.

[mrdeejay]

goodwe requires high-voltage battery bank, which increases the system cost

in rural Sindh at a remote location we have 5 kw nitrox inverter (with a 200 ah x 4 tubular batteries) it runs 24 /7 for our food storage section. It has a customized walk-in freezer as well, now its been around 4 years since installed (28 months of my stationing here) and it has not disappointed for blink of an eye.

This year winters we expect to change batteries. Only maintenance is SG check of batteries once a month & top up, 2nd is solar panel bank washing / cleaning done every alternate day after sunset.

Residential quarters have 3 Tesla units which are equally flawless.

Inverters are all Chinese & tubular batteries are local.

Any basic VM2 inverter will do. You can also opt for Tesla HLE by adding more which can give you option to operate light and heavy load separately. If budget is not an issue, Nitrox or Onyx are best available option in hybrid but they can just run on solar, either battery or grid should be available.

Thanks..
Besides Tesla HLE which is 5kw, any other option in hybrid.. around 3.2kw which also gives option of light and heavy load?

[umans]

Tesla HLE is available in 3.5 well. Recently launched. Nitrox/Onyx 3.6 is also an option but hard to find as they discontinued that.
Prefer 5KW over 3.5 as price difference is not much. You can extend later, even if you don't extend it'll have longer life.

Some one please help or explain the solar system
Blank about it
Need to install a system to run a 2 ton non inverter ac 1 led tv 4 fans 10 led bulbs and 12 cctv cameras
Backup needed only for fan bulbs and cameras
Ac will be operational only form 10am till 4pm max

[nfssaad]

pretty much all inverters have these features.

since you are going to use batteries. keep in mind the number of batteries required.

1.2 kw aerox / veyron has 12 volt, 1 battery. price is about 27-29000

upto 3.2 kw, is 24 volts, 2 battery (some inverters take 48volts, 4 battery)

above that is 48 volts (4 battery)

phoenix tx 2500 (230 AH) 12 volt battery is about Rs 33,000. so keep in mind the battery cost.

[nfssaad]

you cannot run non inverter on solar.

only thing possible is to get 2.2 kw solar inverter with 2 batteries and matching plates for the load other than AC.

for AC, to reduce energy bills, a separate 3 phase, ON Grid (without battery) inverter with net metering.

other option is to get 3 phase hybrid inverter with net metering. i think 3 phase inverter are not available less than 5 kw so you get a 5kw system.

the AC will be connected directly to your meter it will not be connected through inverter. however bills will be reduced as the excess power made by the 5kw system will be fed into the grid, reducing the number of NET UNITS on which you are billed.

Hello, is phoenix Tx1800 tubular battery categorized as AGM or Flooded, i need to select proper option in inverter settings and need some help.

[nfssaad]

it will be flooded

Salam guys I need help on an issue
Installed solar 2 years back if was running fine now all of a sudden solar time has decreased in summer sunset is around 7 now but plates charging goes down around 4 pm and battery power start consumption

Anybody can share what could be the reason solarr plates have gone bad or wiring issue ?

[horticulturalist]

Is there any chance of solar products price reduction in 2022 or 23?

[helper_learner]

Yes if you buy with respect to usd, but for pkr no... they will always rise...

[helper_learner]

Do you clean them (solar panels)?
