Do you have any 12v solar panels

Feshizzy:
Just call in an electrician,

Or

You would need:
1. A circuit breaker
2. A change over switch
3. Obviously some 2+mm cable

Well you should also note our batteries here uses an external charger too because we use batteries bigger than the ups meaning ups can't charge such big battery.

Now for the connection

You would still need an electrician,
Because you can't possibly to toying around with your home distribution box.
Reason is that you have to reconnect all the low amps in the db to another db for the ups.

Well now it depends on your house wiring

Before I proceed further,
How does your generator change over switch looks like?

And the size of your ups?
And also do you intend to power your entire home?

------------
Now lets assume‎
Firstly, you have this kind of switch on the picture attached,

Secondly, you intend running your loads uninterruptedly,
Without minding those big amp draw from ac/fridge/microwave/iron and the rest!

Then we proceed further with the connection,
Firstly, you should note the battery charger should be connected to the ups,
There's a port on the ups sometimes tagged "printer" this is where you plug your external battery charger,
This port is like the mains and not connected as backup as the rest of the port.
In less grammatical version "e mean say when light no dey and you on your ups the charger no go on"

After getting this connected,

Then you proceed as the diagram describes!

I am no artist, but you get the picture?


Note:
You should have a switch/breaker between main and ups.

Now the working mechanism, 
It's pretty self explanatory,
‎
By default,‎
You either flip for nepa or gen

But in the new config,
You also flip for nepa and gen and then
Flip for either direct to mains or ups back ups.

To enjoy uninterrupted supply,
Just turn on the ups, and switch to ups

That way even when there's a black out, you still have your power on and
It surprises your neighbours. ‎

Cheers,
Regards!‎

Nice illustration,could U PLS illustrate to me where to place my circuit breaker btw main & ups...I have a changeover installed already..what will be d function of d circuitbreaker.can you paste d pic of breaker & rating?
This is d pic of my setup
The white plug is to plug to d ups outlet to supply d house.
Tnks for d explanation my nepa-gen changeover is bigger & outside,d pic shown is d Main-ups changeover.My ups is 1.5k a with 20A souer battery chager.
I plugs my charger to main wall switch to charger battery.i use changeover to change btw Nepa & ups my setup is not wired to be ongrid...am scared a surge my damage my equipment,cause fire if am not around.to be on d safe side I wanted a fuse or breaker somewhere to protect my setup.i need the rating of such breaker.
i have witnessed a neighbour inverter got burnt before to ashes no be small thing ooo thanks to fire extinguisher.

teamsynergy:
done with the conversion of the ups to inverter.. na smart charger remain....

Fan blowing in or out which is better

ceejay80s:
FOR TWO YEARS ,I USED THE 650VA WITHOUT COOLING FAN AND HAD NO PROBLEM TILL TODAY, there are time its on for 48hrs straight up , even the 1.2kva worked from 6pm yesterday till 6am this morning with no overheating
if u can get a 24v 30amp or 40amp charger, it will be sweet, 24v 20amp is widely available but its slow in charging and u know nepa light now na (1hr ON,3DAYS OFF)

Ogaceegay, what d best way to install cooling fan to blow air in or to extract air out.

A sad case of a pig calling a goat dirty.

Damn!which pfucking queen?

How can robots pick tea?which kind wahala be this

Na so this sex they hungry women.....I grew up thinking they don't like sex.

How can a sane man go pfuck another man's towtow.what happens his wife own?

@ oga ceegay80 & other gurus is it advisable to put a circuit breaker btw the main distribution board & changer over to my inverter?

[quote author=SolarEngr post=123809898][/quote]Tnks for yo answers...d last answer depends on d size U mean size of inverter or load?

Kudos!I can see d inverter plug side been connected to circuit breaker what is the reason?
Also saw changer over installed in some cases is it to change from phcn to inverter-battery mode & vice versa?can that souer inverter automatically switch from battery to Nepa if power is restored & switch to inverter mode if Nepa sieze power?
Tnks

Let them hand him over to me i have a 7tailed-koboko specially made for him.

Loyalty has gone to the dogs he won slap his former oga.

The temptation is much,he thought he could dash across when d train is 50m away...na only aboki Okada riders dey do that kind stupidity.

His!This man fall my hand big time....just imagine haw he rigged rivers election for bat....now he his begging vfor appointment...may bat disappoint him.

This is d kind of sport that every adulta knew how to play without any coaching even a drunk,a lazy bone even Shehu can play d game Wella.

Most females are so afraid of snake and don't know why. Some can't even stand the sight of snakes on even on the TV. My wife dreads National Geographic Channels because of that.

But they are not afraid of a kingcobra called gbola

So insect no b animal?goosh!

See haw this idiotu is disgracing Nigeria.....let them lock him up with his uncle ekweremado.

Innoson ma nigga!

The north is d epicenter of hard drug business on Nigeriya ndlea should focus more on d north...Kano,sambissa and Zamfara.

The violent passages most pastors used to preach with vigor Amelika want to ban it.

The sudden removal of subsidy was a very bad decision.....
All d nation refineries are not operational no foreign exchange will be saved because we will still import most of d fuel we need.
The much awaited Dangote refinery is not fully operational...could D.R supply us all our petrol need?d temptation of D.R or cabal buying from D.R and selling to other African countries at black market cannot be overlooked.
no plan or palliatives on ground to cushion d effect of subsidy removal even though the previous subsidy payment has not been exhausted.
This 'ill thought decision is going to raise inflation rate over d roof...making PMB next level of hardships a child play.

This is madness!is d aunt not someone's wife.
