1.5kva transformer based pure sine wave inverter definitely

I asked a contact for market survey on connection that will power 2 rechargeable fans, a laptop and minor accessories.
Please is this amount correct?

Guys please I need a quotation (cost)
for a complete solar components that can power a 2hp compressor off grid.

Obnoxious2001:

What are the minor accessories?
This quote doesn't look minor. If it those rechargeable fan, laptop the smart solar kit is your best bet.

Obnoxious2001:

How long do you want it running?

saysoo:

8 to 10 hours.

samistry:
Minor accessories like phones. How much is it for solar kit?

Obnoxious2001:

When are you running it day or night

saysoo:
evening to morning 7pm to 5am.

Obnoxious2001:

This should cost you around 5m roughly

saysoo:
Wow, since it is buisness, i will go for Lister generator. Thanks

Obnoxious2001:

This should cost you around 5m roughly

Obnoxious2001:

This will be cheaper for you on the long term if you are running an ice block
Besides your design requires more of battery backup.

Good luck on your quest sir

Ournolly:

I am curious on which battery can power 2 hp compressor for 10 hours of no sunlight.

That will be like 12 dry cell battery.
What's the evaluation on Lithium battery?

Eldemmi:


Will 5m do it and be effective
Please can you break down the requirements for me.

Obnoxious2001:

Sorry I just did review on it now.
5m can get the materials. Thought not completely

How much can do it then.
Thanks

Why is my solar panel drawing current back when the sun goes down, I decided not to put up loads for two days, I notice rhe current always regressing as soon as the sun become low.i think this my installer don't have full knowledge of what he was doing

Nteogwuija:
Guys, pls how do I prevent my set up from thunder? About 2 weeks ago, there was rainfall and it came with thunder strikes which affected my 1ka inverter, which is currently undergoing repair. I have bought DC surge protector and breaker. But I'm still feeling this might not be enough, cuz someone told me that I can have these accessories but if the house isn't earthed properly that they won't work.

Please what measures can I take to secure my setup from the effects of subsequent thunder strikes?

Thanks for your responses in advance.

Obnoxious2001:


Draw current back?
The solar panel Na Drogba ?

When you say draw back, is it not producing any current or your battery doesn't get charged?


When did you start noticing this

Obnoxious2001:


Go and get an effective earth. Your earth resistance should read about 10-5 ohms for residential purpose and 0-5ohms for industrial applications.

But that aside, Recently I was thinking about this lightening strike.
And I came up with this hypothesis

I was thinking what if I include a AC SPD to the output of the inverter too( reason is most lightening strike are likely to come from the AC side.)

Meanwhile it's just an hypothesis .

Nteogwuija:


Thanks for the response. But is it possible to install earth in a rented apartment? And I also learnt that an effective earthing can be very expensive, reason why most landlords opt for the less effective ones.

b0rn2fuck:
anytime around 4 o'clock observed the current seems to be reversing . The solar panel is new

Nteogwuija:


I think the AC SPD should make sense because I was surprised how the lightening didn't affect the charge controller, because I felt it came from the solar. My thought now is that since the strike affected the inverter, it most likely came from the mains. So I think it makes sense to put an SPD between the mains and the inverter. This is just my layman thought process.
