Hello to all the gurus in the house

Please i need urgent advice on my intended solar panel installation

I wish to install 2* 550Watts Solar Panels
30Amp Charge Controller

My batteries are 2* 220 Tubular batteries and lastly inverter is 2.5KVA Pure Inverter

Please i want to ask;

1. How long will it take to charge to full batteries with the 30A MPPT charge controller
2. How efficient is the set-up

In the past I used a more frugal setup with 4 350W panels and 4 250A LA batteries and get a full charge within a day - on a good sunny day. Albeit with 80/100A charge controller can't remember which. 2 days should be more than sufficient for a full charge unless it's raining heavily.

I bring you bad tidings... The National grid have collapsed this evening....may the sun be in our favour tomorrow.

kristien4:
Same 6mm dc cable, same orientation... i guess its the shading then cos the panels were cleaned recently..no changes.

Then dust is the culprit here!

Abbeyb1ack:
My inverter just shut down due to overload...any engineer within sango axis?

No modern inverter should behave this way, it only just stop supplying. Turn off / on business continues.

True, but some low life inverters will not shutdown gracefully, they will blow a few mosfets if overloaded. I wonder why?

Their life is low.

Good morning guys, please I'm seeking an "affordable" lithium battery & inverter kit for a 2 bedroom apartment

2 freezer 180w
1 Tv (120-160w)
2 laptops
Multiple phones
3 cloud energy fan (10w each)
Multiple light points

If I'll be adding solar later, what capacity should I be looking at.

Dear Professionals

I need to design system for 240kw, 20kva Inverter - Out door enclosure for lithium LifePO4 battery

Which brand will you advise on batteries, Inverter and other components (I was thinking of felicity because of their presence in Nigeria incase of aftersales support and warranty.

Thanks

I think you should consult a professional to handle the project.

If we will assist, you might need to provide us with some of your design details. (I don't think you have any that's why you are probably asking)

Then we can suggest to you options available.
By the way @valto has Lifepo4 cells that can be used to design any watt hour of battery capacity you require.

Na here I know reach
Good luck with your quest

What most people always ignore.. what type of batteries?
those inverters have poor efficiency.

Honestly. I have seen Will Prowse on YT say his sachet inverter does up to 90%+. I am beginning to wonder if the low idle current is worth it with such DC|AC efficiency.


Batteries are Gel.

Valto:
cheapest tubular is about 340k, highest about 450k
my professionally coupled 12v 105ah 1,344kwh lithium battery with 100A Bluetooth bms is 350k to 400k, with over 10 to 12yrs lifespan.

There is tubular of 280k in the market though.

Dam5reey:


The sweetest part is parallel as you want, whether[b] it same capacity or not. [/b]
people are doing 48V, 100AH and 48V, 280AH.

Eh! Wonderment... 😳

redgem:


Have you made purchase from them before?

nope, but i have visited them before.

Pls has anyone experienced this before, an installer i introduced to a friend mistakenly reversed polarity for battery connection to inverter. And now, the inverter has refused to detect battery.. any solution to this wahala?

Abuja people pls since the grid came back on am i the only one having low voltage issues.?

nicodemusic:


Today I explored the 60a mppt charge controller and adjusted some settings.

Brought charging current from 100% (60a) to 34% (20a).

Please check the attached images to see if anything is out of place especially the bulk and float charging voltages.

Battery type should not be GEL if you are using tubular batteries.

Trippledots:

e no dey bro.. unless u are seeing an old post/price

swagifted:

So, you are confirming that they are legit?

E de bro. Like last week sef.

Same here ooo. Inverters even abandoned the Grid.

redgem:

oh yes, there office is before Vodi Tailors in wuse 2.

omo, make this people allow me sleep with AC na

Is it repairable? Can anyone here fix it or refer me to someone that can?

Trippledots:
My sachet inverter when pulling about 600va AC load, draws about 1kva DC power. That's about 60% conversion efficiency. Ambient temps was in the high 30°s though.

Has anybody actually measured their DC to AC conversion efficiency? I'ld like to know what they got. 🤔

What was the inverter powering?
What tools were used for the measurements?
What's the inverter spec?

kristien4:

Location?
Is the inverter coming up but can't detect the battery voltage?

Or

It's not coming up at all

About 3 billion naira worth of cheap electricity lost under 20 hours of the grid shutting down.
