Yingli sell rebranded?
Well my own is carry multimeter go. Test amps n volts of the panel under sun. Multiple them. If it doesn't give anything close to d panels wattage. Go elsewhere.

olopan:
Watch out for those panel prices you are calling, it be a shame that you are been sold a clone or rebranded panels for the price stated.

These your prices don't reflect present reality.

No! they don't but i don't know your source

but my source don't even sell that low and only 450W is the only one available and is the real deal thing.

Erums:


@ 65 onch smart tv
Pop lights 6w each
3x Fan at most
Charging ports etc
Sound system woofer
Few security light
Electric fence.

What is the watt of your tv and how many hours do you intend to use it at night?
The 6w pop light bulb is how many in number?
State the watt of your fan and no of hours to be used at night.
Sound system, security lights, electric fence, watts of these items should be stated as well and the no of hours you intend to use them at night.
Doing this will enable you to know the capacity of battery/inverter/pv that would conveniently power the above mentioned items.

Mumu question 1:

Is it a feasible idea to use solar panels in place of that window overhang cover (the type we do with roofing sheet to stop rain from coming in through windows)?

I have some like that. facing south though

Mumu question 1:

Is it a feasible idea to use solar panels in place of that window overhang cover (the type we do with roofing sheet to stop rain from coming in through windows)?


Mumu question 2:

Said window faces the East. As early as 6:30 A.M the sunlight is coming in through the window intensely.

Is 6:30 AM to 1 PM active sunlight activity enough for any meaningful use of panels?

After 1 PM the location is no longer receiving direct sunlight.



Thanks

Lovely question you got here not so a "mumu" question ..

What I did was first download a compass on my phone to identify sun rise and sun full, Luckily for me, it was precisely running on my fence (east to west), and so I took my time to check this physicaly and it's what the compass says so I did what u see on the image attached...

With this, the sun will be on the panels from 6.40am till say 5.00pm without shades

Think in that direction.

AndroBlaze:


The bold struck me, which particular prices are high there?

I do agree it is better you source the items yourself to ensure quality but you will likely spend more than the quote for the exact items.

I agree the quote is not exactly high, but better sourced by himself.

Good evening house, I’m in a dilemma with having a inverter setup in my build. Please what type of inverter will work for a compact 4 bed duplex? Say for an area that has 3-4 hours power supply a day (so I don’t exaggerate ) and Ild like for the inverter to give 24 hours light when nepa isn’t available.

I have a 2.5 kw gen that can be used to pump water/ microwave and the likes when there’s no light

I just need the inverter to power;

rechargeable fans ( 4 at most since not all rooms will be occupied 247)

65 inches Hisense tv

Cctv set up, (8 camera’s in total for interior and exterior)

Electric fence (size of fence is about 50 by 50 so nothing so big)

And charge phones.

What k.va will work and Can I kindly get a cost estimate or is there anyone that can be referred here that will give one a solid setup ?

Thank you

GET A 4KWH UPWARDS LITHIUM BATTERY PACK 6kwh and above best to cover for any future load.
1.5kva hybrid inverter is ok, though if ur sumo is 1hp and below..you can get a 3.5kw hybrid inverter and use it to pump water if you so wish. get 4 to 6 pieces of 300w to 400w solar panel. you should be fine. remember to get a low voltage hybrid inverter as ur panel combined series Voc is below the working threshhold of most high voltage hybrids.

48V 135ah lifepo4 lithium battery. coupled with 100A(charge/discharge) Bluetooth BMS, in a high quality HDF wooden box, 125A circuit inbuilt circuit breaker

I bought a solar generator rating 230VAC, 12VDC but I have an appliance 110VDC. How can I use this device?

Please confirm that your appliance indeed needs to be fed 110volts DC?

Have you certified that your solar gen can safely carry the appliance you plan to put on it? What is the max running watts of the solar gen and what is the max wattage of the appliance/load.

If the appliance is rated for 110vDC then you need an AC to DC converter to make the solar gen's 230vAC into 110vDC that your appliance needs.

If the appliance is rated for 110vAC then you need a step down transformer to make 230vAC to 110vAC.

If you will be powering the said appliance off a battery or DC source then you need a DC to DC boost converter to make battery 12vDC into appliance 110vDC for example - connecting the appliance directly to solar gen battery will likely be a warranty voiding action.

Good evening all, I hope everyone had a great day?

So I went on a 3 Phase Inverter quest today.

Most unfortunately most people haven't done a single unit 3 phase setup, most have done 3 units 3phase parallel setup..

And my questions went like:
What happens when you have a source phase failure?

Most people haven't tried it or withnessed it because they were always deploying to clients that have 3 phase prewired environments and have all 3 phases always avialable.

To be quiet honest, I was dissappointed at some responses I got.

Now am back here to seek professional advise.

Has anyone done a 3 phase grid tie setup?
If yes, what happens when a phase or 2 phases fails?
Has anyone tried to power all 3 phase with a the same single phase? Most 3phase inverters I saw today were labelled 230v/400v input. and yet the dealers could not tell me if I choose to ignore the 400v part, what will happen.

We live in a country where grid phase drops are incessant. Please i need honest and first hand experience responses.

Thanks all.

From my own view

it is a small setup for Basic loads like
light, TV, Fan and phone charging

While it features a Lithium battery it is design to be discharged sparingly for times when the grid is down for short time so you can have power to run above mentioned loads.

Also note that no solar panel is included but a 2000W inverter, 100Ah 12V lithium battery, 30A MPPT controller and a 5A 12V charger

So in conclusion, it is a good buy if you stay abroad with a stable grid. Hope this helps.

Thank you for the insight.

This thing is just not my forte

Just trying to avoid to spend so much money of fuel for generators this time when I get to 9ja.

We have about 3 x Epsilion 30KVA 384V (with 32 batteries) 3phase inverters running at different locations powering our communication rooms. It's the inverter output that was separated into phases as listed below and not the input.

* Ac - Phase 1
* Servers - Phase 2, and
* Lightings - Phase 3

Please note we have changed 2 of the inverters to Axpert inverter by paralleling 3 units with Felicity lithium batteries due to issues with SMF batteries and changing 32 batteries at a go.

PS: I'm just an end user and not installer.

There is some prework required before you get to 'needing' a 3 phase system.

Do you indeed have 3 phase equipment that will use 3 phase power or you would just like to power your entire house/facility via inverters?

A true grid integrated 3 phase system cannot sync with an incomplete grid - there must be voltage within spec on all 3 phases - you can setup a scheme that drops the grid input (ignore AC/intentional islanding) in case of supply side issues and then the inverter(s) continue feeding the loads with no break.

Perhaps you could describe your system objectives and the loads you wish to power and then people could give you ideas what designs could work.

Depending on ur battery size and type,it will work bro especially during this sunny era

Place it outside like your corridor or something. Inside is not ok. Especially where there is no window by it

Thanks for your contributions boss.

The issue is I want to be able to power the entire house without modifying the Electrical Wiring.
My house is wired in 3phase, My Generator is 3 Phase, Nepa is 3 Phase, Now Inverter is Single Phase.
If you use Nepa or Gen to Charge the system, you will be overloading that phase that is feeding into the ineverter.
I built an ATS to convert Nepa 3Phase to 1Phase Feeds this into a 15KVA Stabilizer which then feeds the Inverter and the Inverter feeds the house via a 1phase Looped input 3phase unlooped output contactor' with this method, the gen doesn't charge the inverter but snatches the
load from it once your turn it one. Then once Nepa resumes, it snatches the load from the Gen gives it back to Invereter, turns off the Gen and charges the inverter while the inverter feeds back to the loads. Don't know if this sounds complicated though. Hehehehe

I have tried to Parallel 5KVA x3 Units but I noticed some things that no Inverter Manufacturer has ever mentioned. " The Idle system consumption is 5 Times higher when you parallel inverters" You will notice that your battery keeps depleting faster than normal even without any load connected. I recorded about 400w or more idle system consumption with 3 parallel inverters.
This gave rise to my quest for a single unit 3 Phase inverter.
Secondly, you will have more devices hanging here and there and thus you would have to deal with more heat than usual.

My intended modifications:
Get rid of the complicated ATS and many other things.
Install a 3 Phase Inverter with inbuilt ATS (Deye in my mind, with Grid Input and Gen Input)
or Build or Buy a 2 Source ATS to handle NEPA and GEN Switching before feeding into inverter and the inverter feeds thee house, I would have a bypass swtch incase the inverter decides to breakdown someday..
This setup will declutter my power room pretty much.

One would ask, " why do you still need Nepa or Gen you should be going off grid?"
the truth is, during rain season, only solar panels don't have enough sun hours to fully charge these our huge battery banks we are deploying. Except we may have to deploy more solar panels which is space dependent.

Please advice me.

You can put the batteries behind that wall if behind it leads outside, drill a hole to pass the battery cables into here, then neatly install your electrical components here.

Second option is to use none fuming batteries. eg: Lithium.

quality response. Thanks … but the appliance is a mini hand sealer that’s rated- 30Watts, 110V in Dc however the machine is 100Wh but 230V in AC. My problem is inverting this 230V in AC to 230DC. I don’t really care about the warranty, I just want it to do it’s work, considering I’ll be using it only during the day

i think you are confusing terms, or the manufacturer wrote nonsense.....no household device will be using 110v dc.
either it has an inbuilt adapter or its 110v ac. send a picture of the device nameplate showing this info you claim

Hello guys,
My inverter spec is as follows: VOC 500, max current on PV1 input 18 amps, pv2 input is also 18 amps. max panel input power 8000kw
I want to use 12 pieces of 600w panel and connect it 6 in series. Now the STC specification for the panel is Pmax 600w,VOC 41.3v, short circut current 18.47, operating current is 17.2 amps, operating voltage is 34.9v. The panel efficiency at STC is 21.2%. Do you advice me to go ahead with this panel since stc short circuit current is already above 18 amps?

This is a fairly complicated design question.

Some of the issues you are facing with high idle consumption may be due to how the installation was done vs actual hardware limits or design behaviour on your devices.

My takeaway is that you do not have actual 3 phase loads but rather just need to power all the 3 phases of your house with little to no mods to the existing wiring.

To this end what brand of inverter equipment do you currently have? I am asking about the 3 inverters in parallel that you wish to dump? Do they have an input current control/limit feature? This will allow you to run a weaker supply (aka) Generator without overloading it and maintain no break power to your inverter loads (I am fairly sure your AC and fridge/freezer compressor will thank you for it)

The Deye 3phase inverter idea works but limits you to 4kw per phase at the current inverter size and also the available config options may not meet all your needs. I am trying to see if you could make do with your current existing equipment hence I asked for the brand name.

If you had 3 Victron inverters, you very likely have all you need to build a robust system that meets your needs.

Bros, you understand perfectly what I'm talking about jarre.
I have Felicity 5KW x3.

Abeg where can I buy this Deye 3phase inverter? everywhere I have been, they are selling the single phase models.
I went to another vendor yesterday who has the capacities I want 10kw/12kw 3 phase but with little or no knowledge about what to answer to my questions. and I don't want to pay N2m+ just to try out something and be dissapointed.

While Victron might be a robust machine, I am not fan of systems that you hav to buy so many auxilary devices to acheive all the efizi you desire in your power room. DEYE or MPP Solar are pretty decent machines that doesn't need much aux devices but the problem now is: WHERE TO BUY?
Nigerian dealers go as far as detaching modules from these machines and will sell them to you as addons. Dollar too no let person drink water drop cup. One would simply buy from abroad and have peace.

All being said, no going back on the 3 Phase system,

Abeg who knows where I can buy DEYE 3phase 8kw / 12kw or MPP Solar 10KW / 12Kw?? Abeg make una help a brother.
