The weather this period is not solar friendly, so PV generation will be poor. So you will have to wait for a good sunny day to check your pv generation. If you still get poor results, then your "used Canadian solar panel" will be the next suspect in your installation, as there are stories of low capacity used panels upgraded with sticker and sold as used.

thank you very much for this reply

If i may ask, when the sunny days are here, what watts or amps should i be generating on a very good day?

Who has any experience with this new product
48v 5kwh going for 800k

fuckboys:
connect to the existing earth.

Okay, thank you.

The more the merrier.


Lead acid will soon be relegated to the backstage.

Price looks ok


But I don't know what battery cell they have or the BMS they use

I'd recommend you buy from Mr Reed or the Valtech guy.

At least you'd know what's inside.

Cheers.

Bad weather!!!
Do not discharge your battery too deep hoping for a better sun the next day.

Turn on only very very important appliances.

Do not waste energy ( This is a problem already among most users)

Plus bad weather I still pump and run freezer daily.

My bank 1 ( lightning/tv only)
Bank 2 ( freezer/pumping only)
Off grid

AndroBlaze:
I still remember being corrected by people on here that inverters that can run on variable battery voltage inputs do exist, though I am still yet to see one sha.

Check for Anern DU4200 inverter, it has the dual voltage feature.

Valto:
Valtech Energy 24v 7.5kwh and 8.5kwh lifepo4 lithuim battery

good evening sir , how much is the 24v 7.5kwh going for?

Thanks for your input guys, i am now conversant with the HF and LF inverter.

Please guys, i was uncertain which 5kwh to go for between:
* Deye 5kwh 48v rack mounted which i saw for 1.1m.
* TBB 5kwh 48v which i saw for 1.15m
* Lvtopsun which i saw someone on tiktok carry out a capacity test and it did well.

I was also thinking of settling for the 5kwh 48v lvtopsun lithium battery, but i dont know if the lvtopsun inverter is good which i was going to settle for the 5kwh 48v because its around the same price with the growatt 3.6kwh 48v, or if it is advisable to settle for the growatt 3.6kva 48v, but any professional input from the group is welcome.

And please how many panels of around 550 watts will be right for the setup?

Hello House, I want to ask a question. Why fdo a lot of installers prefer 200 to 250 watts solar panels rather than bigger ones ?
I know ease of handling is one of them BUT from a performance standpoint, what's their reason ?

Personally, I intends to limit my minimum to 300watts hence it's either 300-watts or higher

Probably na wetin dem use learn work. Sometimes it's really that simple with Nigerian technicians.

weight is one of the major factors. Imagine the weight on a roof carrying like 12pcs of 600plus watts panels. I would rather stick with 400wats panels.

Cworth 420w half cut panels are 20kg in weight, imagine what 600wats plus panels would weigh?

Jinko 610w is just 32kg sha, maybe installers need to hit the gym

Where are you getting your prospective prices from?

I understand the WEIGHT consideration, especially if you have to move them up tall storey buildings with funny roofs BUT then again.

Every Solar panels mainly comprise the Glass and the Aluminium frame - More panels means more Aluminium frames.
Assuming a 600-watt Solar panel weights 20kg, doesn't necessarily mean a 300-watt solar panel would weight half (10kg) of the 600-watt.

of Course, the kind of wood used in a lot of new buildings nowAdays, One got be careful as those woods are weak even while new.

Personally, one major reason I could use a string of 300-watt panels, and not higher is same reason I prefer 2pcs of 8GB rams rather than a single 16GB ram in a computer - Should 1 go bad, I don't loose the entire thing (More like not putting all your eggs in same basket)

But in Solar, more strings means more connections, which includes installation kits, and more work

My cworth panels aren't giving enough yield


I don't know if its the placement cause I faced them South


The sun was pretty decent today but I never got more than 220w from each 420w panel.


I just bought the panels brand new, so I've not been able to test them properly until today when the sun still registered its presence more than ever in a while.

From major dealers of the products obviously, not alaba or roadside vendors

On tiktok there is an on going war and confusion on number of tubular batteries equivalent to lithium battery.

Please from the professionals here, is 5kwh lithium battery equivalent to 2 or 4 tubular batteries of 220ah?

And please can the 5kwh true rated lithium battery carry a freezer of around 100 watts to 110watts over night when fully charged?

FerrariBaron:

This should give over 30hrs.
A 100ah i.e 1024whr(80% DOD) on a 115w gives 8/9hrs.

FerrariBaron:

assuming total of 170w(including inverter consumption)
real 5kwh lifepo4 lithium @90% DOD =4.5kwh
4.5kwh ÷170w= approximately 26hrs

It's mostly those whose clients are on a budget and using PWM charge controllers.

They ensure the panels they use are as close to the battery voltage as possible, with most 150-200w panels having around 12v. That way, not much energy (voltage) is wasted when charging with the sun.

Big panels have 30+ voltage, most of which will be wasted since a PWM cannot convert it to current and just matches the PV output with the battery.

Small panels are actually decent for small setups, especially 12v ones with a PWM controller.

What about DC–AC conversion loss?

That should be an extra 10%

fuckboys:
wow, that can get you mr reeds 16kwh battery.

If i didn't get haisic, it'd definitely be mr reeds.

I would cry after spending that much money and seeing mr reeds price.

I do know the feeling. After seeing his price my mind shake lol however my battery is solid so far. If there is a next time I'll definitely patronizse him. We learn everyday. Lvtopsun brand is great too

Good evening.

Please, anyone with an experience or recommendations on DC cooker? Preferably 24/12v?

The 12V one I saw online has a poor review ...

Thanks 🙏

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

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

One thing you should understand is, the lower the Power, the longer it would take all things equal.
There's a reason most (if not all) DC pressing irons marketed as Solar Pressing iRon are rarely useful to these who bought them

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
