Please, is it advisable for a 5KVA inverter incorporated with solar for a hospital?
Reason be that we want to cut some expenses on diseal purchase and also supply light 24/7 for patients. What is your advice?

whats the size of load ?

Surely advisable, if you think of long term use.

Confirm your load

Cuneddy:
whats the size of load ?

well, load is more than 5KVA , but some will be Isolated.
The idea is only for lighting and fans.
any other load such as Autoclave and X-Ray will be used with Generator. and other light Lab equipment. Centrifuge can be used with the Inverter. Surgery can be used with the Inverter.
Power supply is really a problem and cost of diesel weekly is much.
I just want to know how effective it will be for some of us who has idea for it in same facility (Hospital).

How many bulbs, fans and any other appliance you want to power, and their wattage?

Cuneddy:


How many bulbs, fans and any other appliance you want to power, and their wattage?

22 fans with estimate of 40 bulbs (all ennegry saving bulbs). Other heavy appliances may run on Gen and on demand.
X-Ray and Autoclave won't go in for it.
No fridge will go in too.
Well, maybe centrifuge and chemistry apparatus for lab may go in.
5KVA Inverter.

phewww, the 22 fans are quite much bro assuming 10 fans which you have not mentioned their wattage, the coils of every electric motor draws high starting current this alone make 10fans look big not to talk of 22, as for the lightening no issue though but consider higher kva inverter.

Can't say anything until you do a load analysis.

Promise them nothing .

Load calculation is a must.

The panel pf the Solar is Mono, and written 300w on the carton (2 each in a carton) and they are 5 cartons.
Does that mean the Solar panels alone can generate 1.5KVA power or more since its 2 panels/carton and 300w written?

Sounds funny, but no sir. The power you are looking at comes from the inverter design which draws from the batteries. Now the panel's power rating is for charging the batteries not directly for the load. Hope it's clear

300w panel solar will generate 1100w under max sunlight

So

22 fans of 200 watts each 4400 watts .
40 bulbs of 25 watts 1000 watts

Energy loss is 1000 watts
Add all

About 7000 watts of power needed
You can't empty the whole battery bank.

So 7000+ extra 3000 = 10kva power needed.

So you need ten 300watts panel

And ten 12v 150ah battery
Or seven 200ah battery

Hope you get the idea
This is my rough estimate.
Load accuracy is important

Thanks. I appreciate.

Oga, please explain the bolded.
Op, there is a solar energy community on Nairaland, make your request on the thread and you will get real expert advice.

you have directed him somewhere, that's good.

What you want me to explain , is how 300w panel gives 1100 w at maximum sunlight.


Good.
I know why you ask.
I'm not a marketer but I learn so that marketers won't deal with me .


To cut the long story short

Use Google.
Type
How many watts will 300w panel give

Thanks and God bless.
A humble solar user

Assume nothing like refrigerator and AC is to be used for the 5KVa Solar panel Inverter and its just fans and lighting (Energy saving bulbs) is it possible to power max or 35 fans and the lighting alone without any heavy equipment?

Impossible sir, 'it cannot can'

I meant without "heavy equipment. "

no way

I see why marketers swindle you guys.

You came asking for help from this forum and we gave you the best.

Still you aren't satisfied. We know these type of clients.

They will tell you there's no money. Let them install solar for them.

They want solar to be cheaper than generator.

I laugh.

It's the opposite.

Tell them 5kva solar won't be enof.
A good name is better than money.....
