Is it really rebranded deye 12kw? Heard that nitrox is oem hy voltronic because data sheet doesn’t actually match with deye 12kw m.

[mrdeejay]

share datasheets that you're comparing

[saqibhassan95]

Solar max will be single phase right?

Yes

Is it really rebranded deye 12kw?

yes, it's manufactured by ningbo/dye, and rebranded for inverex
sharing data sheets for reference
nitrox 12kw is "dye SUN-12K-SG04LP3-EU"

Heard that nitrox is oem hy voltronic

no
if you you want ningbo, then inverex
if you want voltronic, then solar max
solar max orion series is by voltronic (rebranded)

orion 6kw dual output is voltronic infnisolar V IV 6kw variant, and orion 5.6 kw single output is voltronic infnisolar V IV 5.6kw variant

@mgalaxy3

there is always 30% added to calculated optimum required load, so that the batteries are charged through PV during the day while 100% load is catered. after doing multiple design evaluations my calculations are based on discharge up to 80% of (Tubular) batteries, so optimum recharge take place during sunlight hours.

under my circle of designers we restrict usage of air-conditioners after 4 PM over the inverter circuit and they give it writing to the user avoiding complaints after system is functional.

If & when required only selected number of ACs' are rigged to work over battery backup after sunset during load shedding / grid failure hours.

Thank you for sharing all these details, i wanted to ask for your suggestions that i have three options to chose from.

1- 12kw nitrox/deye 3 ph hybrid
2- 6kw nitrox 1 ph x2 hybrid
3- 10-12kw ongrid sungrow/huawei or locally solis/inverex if any other other on grid you can suggest please mention.

Now given the loadshading situation in Lhr it’s max at 2-3 hours in day time and 1-2 hours night.

Please suggest me out of these which i should chose between hybrid and ongrid, i am leaning towards on grid with less the cost of inverter but if hybrid should i go with single 12 or 2x 6kw?
Also i currently have a single phase meter but already discussed with lesco personel so shifting to three phase not an issue with green meter.

your total PV input? it will be12kw?

[drag0nslayer]

Yeah max will be 12kw but on start will put around 20 545 plates.
I already have 2 185 osaka tubular almost new and can add 2 more if you recommend hybrid just in case mentioned this.

[drag0nslayer]

Thank you for recommending, and as for orion is that three phase? So it would be better if i go for single hybrid inverter instead of making it parallel right?
I will look this orion after eid and as for this system max pv is 11000 but for nitrox it’s 15000.
Also it’s around 2 lac difference between these two inverters and if there’s no big difference then no reason to pick nitrox 12kw.

there's a problem
solar max orion series (even 8 and 11kw variants both are single phase, yes it's weird but that's how it's) hence we can't use this for net metering
single phase is allowed for upto 5kw
so in hybrid, only option left right now for you is nitrox

[drag0nslayer]

Yes that’s the problem and two 5kw will still be a hassle instead 12kw would be better for me, there should be another three phase hybrid option.
Will hybrid 12kw will be better or ups and ongrid side by side?
Right now 12kw only option is nitrox or do you know any other hybrid three phase inverter? 8kw or 6kw? If that i can do parallel?

[capsat]

GOODWE or Hyundai
are good when net metering is prime focus

there are 3 options
1. if you can live with load-shedding and have a generator, go for on-grid top-notch inverters like Fronius SYMO 15kw which costs around 530-540k right now
2. if you don't want to waste generation during load shedding in the afternoon, want a hybrid setup, then nitrox 12kw
3. (it's complicated but yes it exists, usually where 20-30kw or bigger ongrid inverters are installed) using 2 inverters, one your main ongrid, reliable one with design life +- 20 years, for net metering, 2nd cheaper smaller 5kw 48v system just to run critical load during load shedding with pv input during daytime and with batteries during night) could be 1-2 acs lights fridge etc, in this case, a 5kw pv string will be used with change over, when grid is available, with fronius, when grid is off, with 2nd inverter

[Ali.A.Khan]

Anyone here has any experience with Sungrow on grid inverter? Reviews please.

Secondly, is it possible to use the generator if needed in case of load-shedding/after sunset since the on grid system (with net metering) wouldn’t be generating anything.

[AkbarGr8]

I have an ongrid setup and turn on my generator in case of power failure. Looking to add a small hybrid inverter as suggested in earlier posts to provide backup to critical load.

Also, noticed that most hybrid inverters have generator input as well, assuming the generator can then recharge batteries / power the house if needed.

[centos]

Can we change inverter later after getting net-metering done. Let's say inverter goes bad after a year or two and same model replacement is not available. Can we go with different brand, different capacity. Let's say you had 10KW on-grid inverter and now you want 10KW hybrid or may a 5KW on-grid and 5KW hybrid.

In any case you are not exceeding the max PV limit granted to you at the time of net-metering process, just changing the inverter and not adding more panels.

[centos]

Goodwe 10KW 3 phase is available for around 4.5 lacs. I think it can have 15KW of panels.

[centos]

What are the latest requirement about the inverter for net-metering. Does it have to be 3-phase for systems above 5KW as this document from AEDB suggests. https://www.aedb.org/images/NetmeteringGuidlinesforConsumers.pdf

[saqibhassan95]

Does it have to be 3-phase for systems above 5KW as this document from AEDB suggests.

yes
that's what I shared earlier

single phase is allowed for upto 5kw

[AkbarGr8]

Is this pricing for ongrid?
