Going by your assumption, how many Banks have you seen using large Solar panel. na mostly many small ones dem dey install abi dem sef no get Money, or uses pWm controllers.

Not disAgreeing with you BUT a lot of times also, the so called professional installers are the culprit. Most times, clients are clueLess on what they want hence reason they paying you to be of help. Issue is some of us most times ends up not really putting interest of said client as priority.

Just thought I should ask since we learn everyday. Personally, the lowest I have ever installed for clients are 300-watts

You're not wrong either

But small panels, especially new monocrystalline ones, are okay and good for the roof as their individual weights are spread across larger areas, compared to big panels whose weights are concentrated on a smaller area, which might not be particularly good for poorly-roofed houses.

You might also wanna consider the ease of installment. Some installers just find it more convenient lifting small panels😁 nor be everybody get muscle.

Have you lifted a Bifacial 600w+ panel before? Oh boy

I personally don't like small panels and can't use them. But for those who do, I see nothing wrong, especially for home owners.

Tenants on the other hand will need to maximise as little space as they have with big panels.

Is anybody else's panels facing South these trying times?

What's your yield like?

Another valid point

whereEver you try facing the panels, if sun no dey shine, sky just dey like early evening/6:30am in the morning, your panels go dey give you amperage wey fit make you cry.

for now, I no fit try say I want to pump water Ooo. I need to prepare for the worst. Make people no see me going to rent Generator. I rather just use Generator for water pumping for a couple of hours, than for daily usage. I get 5 Big GeePee tanks hence a couple of hours go fill them which would last really really long (as in Months). For now, still got 2 tanks full so no wahala.

Wonder how we dey for Rainy season, yet to see Rain at all hard

issue be say, any work (new installations) wey person dey do for client now, e go know as e go take run am. Make client no come begin question you any how

From where did you get Deye 5kwh for 1.1m when fouani still sells for 1.3m

Their dealer in Abuja, Electrosun solar ltd.
As at two weeks ago when i asked for the price it was 1.3m, then last week when i asked again they said it was 1.1m, i was even alarmed, but the guy said they had a price review. And as for fouani you know those guys love been exorbitant with their prices all the time

dem use una dey do engagement so as to earn foreign currency. Doubt the entire crowd on that your tikTok didn't think to calculate the KWH equivalent of lithium battery.
MoreOver, comparing 2 entirely different battery chemistry, is like comparing Apples to Oranges. The way and manner you discharge Lithium, ain't same to leadAcid batteries

Yeah i know most of them there are out for content to make money too, but you did not still give an answer at the end my friend, will appreciate one.

Don't even think Tubular.
Please don't even let the thought infiltrate.
The mathematics of 5kwh vs 220ah x 4 with 50% DOD is not worth the stress Tubular will give you.
All the Lithium batteries that you are eyeing will give you a minimum of 5 years, even with 80% DOD, you are still looking at about 7-8 years of ownership. At 50% DOD on Tubular if you get 4 years, you must have gotten premium batteries, or have been meticulous with your 3 months maintenance, using actual distilled water.
Just don't let the thought creep in at all.

Ok thanks for the candid advice, tubular erased from my mind lol, i will get the 5kwh 48v lvtopsun lithium battery tomorrow and then get either the lvtopsun 5kva 48v inverter or the Growatt 3.5kva 48v or 5kva 48v inverter.

So please will 4 panels of 550 or 605 watts be okay for the setup? Thank you.

Yayy the lvtopsun gang . It's a great battery and both inverter choices are good as they can both communicate with the battery. Id stick with a 5kva 48v personally Incase your load increases tomorrow

Make the panels 6 to cater for the moon days like @Fremlin will say.

Oh thanks Collione, i appreciate, so the lvtopsun inverter over the growatt inverter.

And by the way you bought your battery, panels and inverter yourself right? Because thats what i am planning to do tomorrow, then allow the installers get the remaining materials and install.

By the way why did you not buy the lvtopsun inverter when you bought the battery? @cc Collione

My current ac is a 1hp non inverter AC. As much as I know that my 5kva can power it, I didn't bother adding it

Have you solved the error code issue between the inverter and your battery?

You need to understand that some banks did their installation when panels were 300 - 350 W.

and so they are little as they were the latest at the time, with 18-19% efficiency

At least a recent project for sterling bank, used 550W in the deployment

I've recently realized that I need to restart my inverter every couple of months for best performance. Otherwise the MPPT just starts doing whatever it wants (sometimes charging the battery at really low currents and only drawing more power from PVs when I add load).

It's ultimately a computer so that's not surprising. Rebooting is the first solution in IT troubleshooting.

To reboot I turn off pv input and shut down the battery, leave for a few minutes, then turn on battery and PV. I've had to do that a couple of times in the last ~15 months and seems to fix any issues.

mayBe na windows OS e dey use because if to say na Linux or UNIX related OS, I doubt e go be so.
Except say your Inverter dey Hibernate. Don't mind me, na busyBody dey worry me

Well, I have no idea what sort of software it runs on. Just sharing my personal experience

Ah SRNE...and I am about buying an SRNE ML4860 60amps MPPT controller from same brand.
epEver prices not smiling but I need expansion

Was kidding about the OS, such appliances run on firmware, not OS though one could call them OS all na same

Please is your inverter not hybrid? Why buying a seperate mppt cc?

FerrariBaron:

Nope. I don't do (anything) hybrid. Same way I wouldn't buy a Tv just because it's got an inBuilt DvD player even if na bluRay.

Also, it's my first time using an unKnown brand for personal use. For clients, I use mostly Felicity and whatever they provide or their max budget gets BUT for my personal use, I prefer rugged premium offerings which epEver has always been including being Cheapest among comparative ones. Just that nowAdays, what's usually cheap, is now expensive. Buying it used anyways at a somewhat steal price

in this present day, i shouldn't be advising on an overpriced 60A mppt , when u can get a good high pv CC (450V max) 140A mppt , at about the same price!

Please comments such as this says a lot BUT ends up saying nothing. Abeg list them out. Just brands even if na faceLess Ones.

Myself is only buying this because the price is a steal and for personal use. Either way, would appreciate your own list of reputable brands even if na China. I know there are some (unKnown) brands that are as reliable as Premium brands BUT me no dey too try things blindly. Even for client projects, I've got a thin list I use.

I'm a rough user hence need rugged things. epEver never gree fail me, not even the ones I've got since President Jonathan regime.

I sha wan begin enlarge my mental list of brands small small

Name names and shame the devil

I bought more panels than my 60amps Powmr charge controller can take without clipping and asked for help in choosing a PV CC but I got no response

Since this topic has been resurrected, I re-present my question, I need help on the above
