So I have decided to make all my outdoor lighting smart by installing photocell sensors, so there is no need to turn them off and on, they should turn on and off automatically.

If anyone has done this before, which I believe someone has, please let me know what brand you recommend.

As for the indoor lighting, I which to install motion sensors, so if there is no one in the room, the lights should go off. So same question again, please let me know what brand you recommend.

It will make my alternative power setup last longer.

Thanks in advance.

I have visited a facility that does this, and they said that it made a world of difference to their electricity bills.

Just beginning my research on this, and I will share my findings

This is a nice initiative. Please keep us updated

Dishtech:
Eight ( pieces of fairly used 200AH quanta battery for sale at Abuja for 65k. It can be returned for full refund if not satisfied with performance after one week. Reason for selling is because the owner want to replace with higher capacity lithium battery. : 080-6765-two-six-39.

Any chance that this can be waybilled to Lagos. I know a couple of people that could need this

Buy a timer like the one you see here:
https://a.aliexpress.com/_mORz2e0

It's less than $10. You can set the time to come on and go off whenever you fancy. Cheers

There is also a proximity sensor bulb holder for keeping the lights on when someone is near here
https://a.aliexpress.com/_m0MP0Y8

That is if you don't wanna go the DIY route.

I actually had this running in my house, 1 Photocell powering 8x 30w VellMax Flood lights. they go on at dark and go off on day break.
I then did a little it by adding Solar Street Lights, they go on at dark and go off at daybreak too, but during rain season when the solar street lights don't get enough charge, they would turn off on or before midnight, So I changed my Photocell to a programmable timer that turns on the 30W flood lights by midnight and turn them off by 6AM..

Peace.

Thanks for sharing.

I have solar streetlights and that is where the inspiration comes from. I want to supplement the solar street lights with other lights that come on and off on a schedule.

Thanks again,

I deeply appreciate

Smiles, there is virtually nothing new under the sun!

Good day my ogas , I got quotations for a 3.5kva inverter setup, I want to ask if it’s good to go and it’s their way I can cut cost?

3.2kva inverter system

3.2kva 24v Indian inverter afriipower 180,000

Total 868,000

Would love your inputs

Hello house. So I got interested in getting a high wattage solar inverter due to my future needs/load - a 10kva 48V one. I don't want to buy anything less due to the natural tendency to keep upgrading. Current budget will be able to make that possible along with a maximum of 4 350W s and 4 12V 250Ah deep cycle gel batteries (already got the s, batteries and inverter) along with a 100A MPPT charge controller. Couldn't afford the lithium ones for now.

Problem is I don't know the voltage of the s so I'm confused on what arrangement to go with for a start. Series or parallel? Especially knowing I'll be adding to those s with time. From what I've read so far on the thread, I deduced the batteries should be connected in series to get that 48V.

PS: I'm not DIYing, but hiring some engineers who have just a little bit of experience in solar installations. Hence the questions.

Lol with such a budget/materials already!!! My oga you don cut enough!!

I will not use that controller anyway. I should advise you to get a better charge controller, but I will be restricted to do so. Cos, you are looking for how to cut costs.

You want to spend 340k on batteries and you intend to kill it with a 30k controller? Nà wà ó

Please who repairs inverters in Port Harcourt?

I have this Transformer based inverter that's been installed somewhere a couple of years now.

Yesterday, I was told the lights started flickering and they were seeing a red glow like something burning inside the inverter (no smell though).

Na advice be this or you're making jest of him? I hail o

Is there any reason u want to pull 2,500w out of 2 lead acid batteries? I don't no ur load but There are flaws in the quotation. Cause I think
A 2.5kva inverter with continuous power of 2kw n surge of 6kw will handle ur load just 5n n u'll get 1 for 150k.
D charge controller is pwm n u won't get optimal conversion from ur s go for powmr. Someone here has some units... 1 is 62k (last I checked).
I'll advice u get 2 400w s(800w) for 200k than 4 200w(also 800w) for 240k.
If ure in Lagos u can get 6mm cables in alaba for 1k/yd.
The change over is too big. Buy d medium 100a type. U won't b pulling more than 10a through it after all. It's 2k.
Don't no why he's getting big PVC. The normal PVC will accommodate 16mm cable just 5n. It's 400 for 1 trunk. U can't use more than 2.
The components connection cable is too low for N900/yd. U need 16mm n it's 2200/yd.. 3-4yd max. U need to components close to each other.
If u can up ur budget small. U can still get 130a lifepo4 battery 8 pieces (400k) plus 40k BMS. This will save u from buying battery capacity monitor, battery rack, watching out for 50% DOD n change d battery in 2-3 years of use.

It was replaced by 40kwh LiFeO4

Kai that choice of inverter for that huge LFp investment Bro. Wetin happen na

jonescosmo:


Hahahaha, It's actually at the airport now to depart shortly. But you can see the package, Its huge I must say.
I bought it in COUNTRY Recommended by One of Us Here
Price @ about N3.3M

Interesting, didn't know the 16kw Deye is now in naija. The 8kw is already a monster, I can imagine what this will look like. Congratulations chairman

your plan is seriousLY flawed, only 4 batteries on a 10kva non hybrid inverter?... the no load consumption of the inverter alone will run down 2 batteries in a day...so technically what you have is just 2 batts?....n this ur upgrade plane...being leadacid batt u went and bought...so u now intend to be adding batteries to the 4 batteries u have already-- another fatal flaw...

if you have big loads, you shud hv a corresponding deep budget to go with it, if not...it will end in disaster. 16 batteries is the minimum you shud have if you are going for 10kva inverter....if not just get a 2kva or 3kva 48v inverter simple. alternatively you shud hv bought a lithium pack, say 14 to 20kwh, then when funds come..you can add another.

lastly, how did u arrive at the conclusion that you need a 10kva inverter

This stuff is huge man. Height 77cm by Width 47cm by Dept 30cm. Take your tape and draw up this size and see what it looks like.

I should have opted for 2x 8kw

Over big dey worry this 16kw

Current load is 1.5HP AC - the power saving type, 240W Gaming Laptop, 100W 50" TV, over 20 15-30W light bulbs, water heater.
Additional TVs may be added in the near future, at least 2 DC standing fans, and possibility to add, 1 or 2 more ACs. Electricity is fine for now but certainly not sufficient hence the few batteries and poor but cheaper battery choice

Oshomo12:

Maker is Sunfield. Same manufacturer as the s.

My oga, please ignore the cost cutting

As much as I wan cut cost, I also need durability even if it will cost more….. durability always pays in the long run

Which charge controller do you advice I get

Though the day time loads aren't stated but charging 5280wh tubular battery bank to daily float from 800w pv will be difficult unless grid will give 70% while pv will give 30% . If not 1600w pv should be considered.

Sir, I advice you take your time and plan well by consulting widely. Solar is not about throwing money about but rather making every money you spend count.
If you're not on budget and you intend to enjoy energy independent, then plan for 10kw inverter, over 3m 28kwh Lfp battery, huge pv and other accessories.
But if you're on budget as electricity is good in your area, 14kwh Lfp battery, 5kw inverter, about 4kw pv and accessories will solve the listed problem only if you can have a handle on your inductive loads and other loads adjustment.
You may do proper audit by deg your loads... Give time for individual loads to turn on and off.
My newbie advice..... Cheer

Already got the 10kva cos prices keep going up. Was advised to get it now before things really get out of hand
