You’re a very smart individual. Number one yard stick for me when spending on anything in this economy is value for money and you understand this pretty well.

Even if it’s grade B cells, it’s still going to serve you pretty well and for a long time.

900k now per my last inquiry a few weeks ago.

Nice one Chief, we made the breaker box though

With the knowledge I have gotten from here, decided to upgrade my solar

Got 4.2kwh battery from mrreed

Got breakers (prewired) from dam5reey1

Got a 3.5kva inverter from Bread

For now, will focus on using grid for charging as panel isn't available for now

Please house, on a cloudy day would there be (significant) difference in the output of 8 PC's 250w panel and 3pcs 650w with similar efficiency

You should be fine as long as cabling and so on is done properly as what you are doing is pretty modest. Seeing as this is a slow day on here, I'll quote the best post from diysolar on this:


https://diysolarforum.com/threads/can-i-over-panel-a-growatt.58714/
The good things I heard about overpaneling with Growatt was one of the reasons I went for their brand (yet to overpanel though). There is even a guy their claiming he had 23kw connected to my 5kw inverter with no issues lol.

HeavenlyBang:
Lol, before na Cworth, then Firman, now Bread. Personally wouldn't pay any attention to what that guy uses tbh. He mostly just parrots wrong information anyway.

brightk:
u won't even see 26A from ur total pv so u re gud to go. Even if see above 22A, the inverter will clip d power towards its max.. I have a 6s2p (jinko 580w) on an ivem 5048 inverter with max input current of 20A. my own view is dat if u see 70% from ur pv output u re fine. Certain factors limit wat u can get from ur pv, sun direction, title angle, intensity of sun irradiance, cable distance, cable size etc.

easyyoke:
Wow. Thank you so much. This answers all my
Questions. And I had even asked on DIYsolarforum, I did not even notice this thread there. Thanks so much

Creditalerts:
an expert once told me that most of the lithium battery we buy in Nigeria are grade B cells that the real grade A cell are very very Epensive

ValtechEnergy:
perfect installation of 4pcs of VALTECH Energy 48v 17kwh lifepo4 lithium batteries

Pwm users this period....

ask4bk:
You know him right?
He gets to my nerves with the way he blabs some wrong info confidently. Wish he was on naira land and we put him to his place

OgogoroFreak:
bread has inbuilt charger for grid?

Peterlove11:
Go with 3x650w, it will save you some cabling. Too much cabling sometimes dey affect efficiency

KudozInteriors:
Good morning Solar Gurus🙌

Thank you all for the great work done here.

Please I have a question:
I want to upgrade my Solar panels and from my little research, transformerless inverters thrive on more volts and panels with more volts and less current are good for solar connections as with lesser current, your wires don't heat up. And normally, when a panel has more volts, it will have less current.

So I wanted to sell off my panels and get new ones as I currently have 4 panels acclaimed to be 550 watts each and 2 of them are Canadian of which I'm not sure they're even up to 450 watts.

I wanted going for 6pcs of Jinko 550watts panels which will amount to 750k (125k each) and produce 240 volts and total of 3300 watts but my good friend that is a well trained installer advised me to buy the kind of panels he's using…said he got them from a reliable source: 380watts for 85k each and produces 37volts. If I buy 10pcs, this will cost me 850k with total of 3800 watts and give me 370volts against the 240 volts from the 6pcs of Jinko and lesser current for my wires. According to him, vendors buy from his source and change the label to 450 watts.

Please what do you advise I do?

Thank you do much🙏

HeavenlyBang:
Depending on your MPPT, three 650W panels may not supply enough voltage for ideal performance. Keep that in mind.

You may be better off doing 4*550w for a little bit more money.

brightk:
Apart from deye and srne please which other 6kw inverter is durable and rugged with medium price.
