Please I need someone to critic this

5KVA growatt inverter-Available
15KV felicity lithium battery---To buy
120A charge controller---To buy
I have like 14 Jinko s,440W--Available

Band A is showing me shege

Ensure you buy full capacity ones..

Is the Growatts not hybrid?
9 s can go on the Growatts and remaining 5 on a 60A controller..

How much them Dai buy am?

Looking forward to selling mine once my LFP batteries arrive

Used to be around 60k or so. I am still looking for buyer

Mrreed:
25.6v 100ah 420k
Made with Gotion cells

25.6v 280ah 840k
25 6v 314ah( actual capacity >330ah) 870k

NB: They are all made with wooden box for now.
Check here to see what they look like
https://www.tiktok.com/@abu_tawamaan?_t=ZM-8uWIsocycit&_r=1

These batteries are with BMS and Also LiPO4? getting the 25.6v, 100ah, with 1.5kva, will it handle
120w freezer
60w laptop
100w miscellaneous

For 10hrs?

might be using grid, no need for now

Obnoxious2001:


After he buy everything he go come dey proce installer 100k .

Nobody talks about this stuff on this thread.

If you are going to spend on what has been recommended (the recommendation is Valery valid) be will to spend well on a good installer.

Is funny a lot of people will spend good money on equipment the spoil it with cheap installation....

Inverter will damage then you will hear this product is not good

Crossed an installation yesterday. More than 30 solar s mounted directly to the roof. No roof mounting kit, cables running bare on the roof.


Often a product of "I can do it cheaper" group of companies.

Well, it works. Until it doesn't.

With a continuous power draw of 280w, 7 hours at best. You have to for the inverter power consumption and its DC to Ac efficiency.

Can I safely power a 12V CCTV camera directly from a 12V battery (charged by solar)?

I have a CCTV camera that normally runs on an adapter rated for 12V DC, 2A (input: 100–240V AC). I want to by the adapter and power the camera directly from a 12V battery (such as a sealed lead-acid or LiFePO4), which is charged by a solar system[b].

[b]My questions:

1. Is it safe to connect the battery directly to the camera’s power input?
2. When fully charged, the battery can output around 12.6V to 13V—is this safe for the camera?
3. During solar charging, voltage can reach up to 14.5V—would this damage the camera if it's connected?
4. How do I ensure correct polarity when wiring?
5. Is it safe to charge the battery and power the camera at the same time?

Any advice, experience, or wiring tips would be really appreciated!

Yes I have tried something like this before not with camera though but a DC fan of 12V

But be sure that the camera won’t spoil if it gets a voltage above 12v

quite agree with you BUT paying millions to an installer, doesn't automatically make an Installer good enough. Na your work to employ services of a good installer, then negotiate with them. Sometimes, na even the Cheap one that might end up serving you more.

3. During solar charging, voltage can reach up to 14.5V—would this damage the camera if it's connected? YES except the camera's input voltage has a range of between 12v to 15v
4. How do I ensure correct polarity when wiring? Use colored wires to differentiate +ve and -ve e.g (RED for Positive, any other color apart from BROWN for Negative)
5. Is it safe to charge the battery and power the camera at the same time? YES and NO - it just depends on how the camera is connected

You didn't tell us how the camera's charging system is. MayBe the camera has an external 12-volts charger which ends up with an OutPut of a clean 6volts, or maybe the external charger accepts DC voltage in range of 12 to 15 volts which could be dirty BUT outputs clean 12-volts which gets fed directly to the Camera.
Now should you make this by by directly connecting the Camera to the battery, even if it's same 12-volts, you risk damaging the camera due to how dirty the voltage supplied is.

If the Camera's charger output 12-volts, and you sure the Camera also accepts input of 12-volts, what you could do is ensure you do not draw the current directly from the battery BUT it through something that would clean it up to remove noise so it's clean

A simple way of having such clean output, is to either build the circuit, or it through something else that outputs clean 12-volts.

A lot of charge controllers, have 12-volts output port BUT you need be sure your battery backUp is 12-volts because that port is not always 12-volts BUT the voltage of the battery bank hence is your battery bank's voltage is 48-volts, then that port is automatically 48-volts BUT if it's 12-volt, then the port would also be 12-volt.

If you're to build one yourself, you would need a couple of diodes, capacitors, etc and know how to do things yourself

I mentioned the charger specs for this camera.

My battery is 12V DC, does this mean my controller port (I have a controller with an output port) will produce clean 12V?

If yes, then I think it would solve the problem.

That's what I'm not sure of... Hoping to get an answer here.

bkuranga:

If yes, then I think it would solve the problem.

if the battery bank, not just the battery is rated 12-volts, then the Charge controller port would be 12-volts and a clean one devoid of noise.

so even if you have 1 or 2 or 3 or even 20 pcs of 12volts battery, so long they are all connected in parallel, then it's still a 12-volts backUp which is good for your need.

If you have just 1pcs of 12-volts battery, then you are good to go.

But if you have more than 1pcs of 12-volts battery, and you not sure if they're connected in series or parallel, would suggest you let us know first.

Now what is noise - To speak layman's language, Noise is when the output is not stable and could increase or decrease any how

Try a DC to DC converter to ensure safe stable voltage.

It will work

Hi guys, can one safely connect 2 different LFP of same capacity but different brands in parallel.Has anyone experimented with this before?

fuckboys:
it has, it sees my WiFi network but refuses to connect to it.

Hmmmnn, I had similar issues trying to connect the wifi module of the growatt inverter. Try these two fixes:

1. Ensure no special characters or spaces in your wifi network name and .

2. Ensure your wifi is outputting on 2.4ghz frequency.

It was number one that caused my own issue.

BTW, nice to know Junctek now does remote monitoring.

Does anyone know any other reliable Jinko supplier apart from Fouani? They are always out of stock of Jinko products. The day before yesterday i checked and there was plenty, today they are totally out of stock!

Jinko from fouani cannot keep up with the present demand. We are shifting to Ja solar from same fouani soon.
