After much delib, Finally settled for:

Jinko 580W x9,
Growatt SPF 5000ES and
Pylontech UP5000 5.12kWh x2

I guess it's time to find a reliable installer and I'll love recommendations. Thanks alot

By the way before getting an installer google up yourself in relation to your set up. At least a bit of knowledge in solar in other to avoid frequent ok ok ok...Fund is hard to get; shine your eyes. Check your manuals before the arrival of the installer. Enjoy your fund.

Yea I need the answer too cause what I have been seen on that controller is lead and lifepo4 only. No edit settings for Li ion

Compatible with all batteries.
LifePO4
Lead acid
Lithium ion at 3s, 4s, etc
It is written in the manual.

erazer:

Bros, is these charger controller compatible with lithium battery? and can i use 2 250w panel on 100ah with these controller since it's mppt.

Yes
Max pv is 260w at 12v; 520w at 24v.
You can share the spec of your pv pls.
This is mppt. Currently using it for lithium ion.
Compatible with all batteries.

Series both panels and the cc will do the rest.

jonescosmos:


You will loose more with more cross-section in relation to distance bro.

Do this when you have the time: Get a 12V Okada Battery, cut a 30 meters of 4mm PV cable, use it to power a 12V Okada bulb. Do same for a 10mm cable, same length, Use a lumen tester or use your eyes to test the brightness of the bulb, come back and tell us with which of the cables was the bult brighter.

I did this experiment months ago.
I used an app to measure the lumen.
Ethernet cable vs regular flexible speak wire.
Difference was clear as I did roughly 4yrd (3.6m). Cable size and type matter. However, good cable goes beyond large bristles, quality matters too.

Drgreatone:

Guess that's true. My 2kva/1600 watts shows momentarily the overload sign wit my freezer start up surge of abt 900watts. My previous 1kva afripower cant start my freezer.

Is your freezer up to 130w?

gr8skillz:


19.5V with an output of 3.33A and 65W.

These are the common spec

Here is the picture (it amazes me to be see 150w written on it)

150w oops!

Hello gurus.
I need a built package that can
1. Charge my PC (HP 15 11th gen, supports type C)
2. power rechargeable fan (or DC fan)
3. power router
4. power one light bulb

...for 6-12hrs

Dollarnaira, Penuelseun and other bosses, I missed out on something like this you built months ago (dollarnaira I think). Abeg help me build as I don't think I can handle this DIY myself, make I no burn Lagos.

What is the watts of your charger?
You can upload pix.

gr8skillz:


...can alternate between the PC and Fan. I can also leave out the bulb.

Noted.
A 12v or 5v dc bulb will suffice.

To those running solar, I'm just curious. When last did you use your generator? Did you have to sell it after installing your solar?

You just woke a memory in me with this question. 3years without a generator running. I need to go check it out tomorrow.

funny. Even if one wants to watch hw wld u know wen it's 12v, even in a case its on while slpn. So no bms that can cut off at 12v?

Dc display meter

Machiny:
Have always wanted to make a smal pack for a rechargeable fan, but my concern is charger to use and where to get bms. Can you pls detail your process.

The charging profile of the fan fits. The problem is the bms that will cut off at 12v is the issue here. Unless you act as the living bms i.e monitoring spirit . I am a living bms though.

Hello Chief.
I'm curious. If batteries have short shelf life, how do manufacturers and sellers store them in their stock before sale which may take months?

Most of us store batteries above norminal voltage which is the beginning of degradation. Store batteries at norminal voltage for a period of time and charge once in 60 days. Lithium ion can stay longer than LifePO4 but LifePO4 has lifespan of roughly 10yrs while lithium ion is less than 4 or 5 both at 80%.

jonescosmos:


Please do not store your Lithium Batteries for too long without trickle charging them from at max 3 months interval.
They might gradually deplete beyond DOD and you might need to jump start them and there are also chances that some of the cell might not operate as normal as should be after that.
Lithium Cell Warrantee does not cover this scenario.

PLEASE TAKE THIS SERIOUSLY

Definitely bro
Obviously true.
Trying to compare.

jonescosmos:


Buy them in this order: Inverter>Battery>Panels.

Reason: Inverter has a long shelf life, Batteries has a short shelf life, Keep them too long, they would sulphate or discharge beyond DOD, Panels will be exposed to breakage and other risks when you stock them.

Secondly, you can start using your Inverter & Battery when you grab the batteries and add Panels later.

Third is that the price fluctuations affects Inverters and Batteries more than Panels.

I hope this helps

Depends on type of batteries
Lithium generally has nothing to do with sulphation.

Trippledots:


The landlord has a share of the problems too. Whenever I hear or read about a client that went with an Installer to market, or went to market themselves and then wants an installer to come install, especially when the client has little to no knowledge of market tricks or installation experience, I just feel they are setting themselves up for trouble.

I recently had a client that wanted to install a 5kva, 15kwh lithium system. I was recommended to him.

I went there did audit, discussed different options bla bla bla. I drew up three different quotes later and sent to this guy, after days of market searching and what not.

After sending him the quotes, my guy said he has run low on cash and is waiting for salary for the month. Month end camd and went still no response, so I sent some messages but he didn't reply after reading my messages. I contacted the wife to ask if he was ok, she said yes that he is just having car issues and is repairing it. I was wondering why car problems will make you not reply simple Whatsapp chat.

I just went silent and went about my normal life.

Few days later, baba called that he is in Alaba, he has gotten the battery, the inverter, this, that...I was like 😳...then he said he wants to pick up panels that should speak with tye seller to confirm if they are original etc. I turned down the request that's I don't do that, especially since that is someone's business and I didn't direct him there.

Long story short, he bought fake panels (likely 250w rebadged as 400w), over priced protection devices setup, not very original PV cables etc etc. At the end of the day, he was still complaining that he spent more than his budget. I just 🤐

It is the issue of trust that most installers exhibit that will make most clients do this. Most installers will add thier entire problems on materials and still buy fake at the end. It is better for a client to shoot himself in the leg than someone else. No be person add over 1million to a product here?

To curb client like this, one will go with him to the market together while he makes payment. Give him the cost of installation and move.
