How much sir?

I may like to know more about this 4G CCTV.
I saw one set few months ago that worked with an external solar security light. Meaning you don't need to connect it to internal power source.
It's powered by solar source together with the security light mounted around the compound.

odimbannamdi:


Please share pics of it and specs, if possible.

Thanks

You can get enough pictures of it online. Specs depends on the type you eventually buy. You can get more info from wilmaria.

If you are not talking about hybrid inverter, then go for SMR. That inverter is crazy rugged. I've not switched off mine for about 5 months now. It works 24/7. Bought it February this year.

Idle power consumption.

I was out of the country for 5 weeks and yesterday I was in transit. The number is fine.

OK will get in touch

Looking at south south weather, I'm trying to design two setups (with an intention of picking the best) that will give me daily battery float with load management.
Please, someone should help and rearrange the diagram for me. Add what you think is necessary and remove what you think is unnecessary.

NB: Batteries are tubular.

Pv Array 1 will face south while Pv Array 2 will face west in diagram one and two.

The second diagram are to be installed separately.

In the first diagram, I intend to connect the output of the two CCs in parallel to the battery bank to work in sync.

QUESTION: 1. In the first diagram, can Pv Array1 and 2 charge the battery bank simultaneously?
2. At what point will I allow one array to sleep?
3. Is installation of HA02 really necessary since monthly equalisation of these tubular batteries are mandatory?

Your advice is highly appreciated all

If you must try this model, you should be thinking of North and South, West does not even come into the equation at all at any time of the year.
It is better not to install solar at all than to have your panels facing West

Thanks for your advice.

Are those diagrams in order and which setup from the two is the best for southern weather?

In diagram one, could the two pv arrays charge the battery bank simultaneously?

Is HA02 installation really necessary for tubular batteries?

Where could MNDC115 or 300 be installed in that diagram?

Thanks for the response, boss. However, I will pass, as I would have preferred a 12v inverter. No strength to deal with battery imbalance issues...

OCTAVO:

Nice one. Any idea whether it is an hybrid (incorporating a charge controller function)?

Personally I like segmentation that do not have a single point of failure. So your picture 2 is similar to what I have, one in use during the day, the other at night. Similar to someone having 2 generators.
What's the watt meter for? DC or AC loads?
The charge controller already has a meter if what you are trying to measure is the power generated.

Sticking with 12v also has its own limitation.....if you are running above 1kw I don't recommend a 12v system. You won't have much imbalance with single string of higher voltage else go LFP

[quote author=ojesymsym.

Though the installation of 48v system in my case could be cheaper and also have the lowest current output (leaving my family and I with more voltage to play with) than 24v system, but the simple method of managing 2x230Ah instead of 4x230Ah always attract me to 24v setup.

Please, I'm still waiting for more opinions from people that have installed 4x200Ah tubular battery bank connected to two separate pv arrays with two CCs.

This is very wrong! Any time from 11am till 6pm, west is a very sweet spot to install panels. Give it a trial, u will SEE.

West Where the sun finally sets towards evening?

Somewhat correct, 11am to 6PM you will have harvest. Compared to 9 to 4pm

... And it is overhead from about 11 to 12. If your roof isn't steep to the west, you will enjoy nature from from about 10/11 till sunset

This is soooo wrongly wrong boss... The wrongness of this statement cannot be overemphasized!!! Lolzzz
On a lighter note...

For 4 years plus, my PV Array setup is split into two: East and West. Even with fridge, TV, fan ON, battery can still float around 6:10pm, depending on sun intensity of course. You can NEVER have that with South or North Orientation, irrespective of sun intensity

That Sunset charging is usually very advantageous...

I mostly split Arrays for clients into South and West; or East and West... Other times, I just allow everything on the south. But if I must split, West MUST be a consideration. In fact, I split because of that West Orientation; that sunset charging helps the battery a long way through the night. Only few times have I used South and North due to constraints

So, if you're going for single PV Array on one Orientation, definitely South is priority... If you're splitting into dual arrays, West Orientation is inevitable; i.e South & West or East & West.
Cheers

Edit: I see Oshomo12 and Dam5reey already reacted to that... Cheers

If all batteries are same brand, same rating, same age, and same technology, just parallel them into one single 24V 400Ah bank

Two PV Arrays can charge same battery bank, as long as the system is properly designed.
I have two PV Arrays on a single 24V 400Ah battery bank with 2 sets of inverters connected to the battery bank.
The two PV Arrays ALWAYS charge at the same time.
You just have to know what you're doing

This HA02 matter has been tackled severally. It's your choice. Just make sure you install it as you're installing the batteries... Not later.
And if you're paralleling all 4 batteries, use on HA02, then link the midpoint of string one to the string two

MNSPD DC should be installed at the downstream of the PV array; at the Line side of the PV-CC Isolation Breaker
MNSPD AC should be installed at the line side of the Inverter AC Input Isolation Breaker.

Cheers

Does the roof type play a role here?

Okay, roof type plays a role.

alstacs:


... And it is overhead from about 11 to 12. If your roof isn't steep to the west, you will enjoy nature from from about 10/11 till sunset

I think it is dependent on the orientation of your roof. If your roof has just two sides, that is south facing and North facing and you are located in the Northern hemisphere, you might want all your panels to be south facing.

If however, your roof has four sides, then it's best you explore more if I'm in the northern hemisphere. I would personally have panels facing east, west and south. This is simply because the sun is moving and I would like to capture as much of the sun's isolation as I can. The panels facing east capture the early sun, the west capture the sun afternoon / later afternoon, while the south facing would do some averaging.
This has worked for me and so many professional installers/ installs.

Has anyone here ever connected or linked solar power to his house gate/fence wire at night for security purpose?
How is it done please?
