Can I run the hole wiring of the below fan with normal 1mm AC wire including the DC line(from battery to the fan)?

NB: The solar panel is not included and battery position is a bit far from the fan

I need your insights please.

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 bypass 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!

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 password.

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.

dollarnaira:
It will work

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

Pls aside Faouni I need other reliable online stores where I can get panel and inverter from

FEGEITOK:
SRNE and Schneider.

Rest of the house, the amplifier and the fan are on the SRNE.

Smart TV is on the Schneider

bassdow:
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.

Crossed an installation yesterday. More than 30 solar panels 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.

My people.
What is the best recommendation for a 1.5kva set up
?.
My 1kva luminous just developed fault, I have a decent tubular battery.
I just got 2 africell 330 watts panel. I am just confused as to which inverter I should go for. Ideally I want to be on the tubular for now then replace much later with a lithium battery.

Please Inverter recommendations Biko.

Bless

fuckboys:
wow, thank you bro. The first option was my problem also.

Connected and can be monitored anywhere in the world now

Good to know that the Chinese are still predictable

BTW, where did you buy the monitor from and which exact model did you buy?

Hello house,
please what is the effects of connecting panels of thesame watts but different VOC together.

Ahyjo:
Please I need suggestions on a 2.5 - 3kw hybrid inverter with a PV input voltage of at least 180V and max pv array of close to 2500?

bkuranga:
Thank you, I will place an order for this.
It will be cool if I can get something around 10A.

Machiny:
can this work without battery?

mctfopt:
Nigerian electrician hates to ground a house.

It's appealing the level of no protection they put up while wiring the house.

87% of Nigerian electrician needs to go back to tech school for a one month intensive course on electrical protection.

Nothing makes me sad to see multiple houses without basic electrical earth and lightning protection.

HeavenlyBang:
Using an inverter without a battery of any sort is impractical in Nigeria.

What happens when sun suddenly goes down or there's cloud cover and your panels can't supply the needed power instantaneously?

Inverters marketed as being usable without batteries are only valid in countries where grid supply is constant. So when any of the above happens, the inverter draws power from grid to fill up the gap.

They av 10a bulk converter. Even 20a
