Na good product.

You can buy in China for some discount

any idea on alpsolar, price is moderate, they seem to capture my attention with thei panel oversizing but with no dual mppt input i tire once....

mctfopt:
Check Techland and Jiji.

.

Must've missed your DM.

Cheers

boss u nor just like me. Even deye price de learn for where solis de

boss where i take see the price fear hold me oo.. abeg u get plug. me i don dm u tire u nor de respond

Apart from deye and srne please which other 6kw inverter is durable and rugged with medium price.

easyyoke:
Make una epp me abeg, my ogas

u won't even see 26A from ur total pv so u re gud to go. Even if see above 22A, the inverter will clip d power towards its max.. I have a 6s2p (jinko 580w) on an ivem 5048 inverter with max input current of 20A. my own view is dat if u see 70% from ur pv output u re fine. Certain factors limit wat u can get from ur pv, sun direction, title angle, intensity of sun irradiance, cable distance, cable size etc.

Mrreed:
I stand to be corrected but a100a cc controller already tells you that you won't get beyond 2700w at any point in time even if your PV is up to 4000w.

it doesn't work like dat.

Machiny:
this is from the booklet they gave to me. Seems they have different kinds

I don de discourage already I have one of dia booklets dat indicate the pv array is 4000w

Machiny:
16 Damiete Drive, off Full Gospel Road, By Odili Road, Port harcourt . 3.5kw is 3000w max pv, while 4.2kw is 5000w. Thinking of firman my issue with them is ordering online but has service center in ph, but no walk in store for purchase. Noticed firman is almost noiseless

Except the company is not being truthful, on their catalogue its 4kw mppt....were u able to max out the mppt value, if yes how many panels did u attach?

you may need to deploy proper lightning protection

and lightning protection in nigeria can be tricky

people are buying indelec prevectron fro domestic house which as wayo. you dont need indelec for a domestic house. indelec is designed for protecting industrial facilities or commercial buildings. by design a prevectron attracts lighting so it is often installed in a secure /isolated part of a facility so your lightning strike does not affect anything

the regular arrester will be struck by lightning if the lightning comes close to the building

the other issue is earthing. conventional wisdom is everything should be on one earthing ring.

but if you have high earth resistance, the lightning strikes the arrester, goes to earth, then goes back into your system and fries everything

so i personally prefer to put my lightning protection separate from mains earthing - especially as no one does routine integrity testing

also and this is the big kicker - in many domestic installations, earthing is either non existent or very poorly done. you want resistance of less than 10ohms. most people will drop one earth rod and call it a day. you now test and see resistance of 200 ohms or more.

it is especially problematic in lekki and beyond which is sandfilled. so you actually have to dig through b or more metres of sand to get to the real earth

f you have a tank stand in your compound separate from your building put the arrester there that way you dont have to worry about surges induced by the arrester traveling to earth

also install surge arresters on the lines from your panels

i have seen articles on the internet where experts talk about bonding all earth rods together to keep voltage potential to a zero value.

Even the business plan, According to Starlink is at capacity. Unfortunately I keep hearing people saying that they can activate the Starlink.??

starlink can b activated anywhere even if location is @ capacity

You cannot build hotel in residential areas, or build office buildings in residential areas. You can’t build shops in estates that are quiet and no pedestrian traffic. Those are the considerations. I was discouraged from converting my place to short lets because of environment.

funny enough most of the coded guest houses are in coded environments

Pnutmillionaire:
Is there a possibility a firmware update might be affecting my inverter's ability to see pv ?
10 590w jinko panels from fouani is showing 0 watts from pv side but working well with nepa.
The wire of 5 in series was tested and it got 240 volts.
There's also a little spark when the dc spd is turned off/on

a little spark on ur spd calls for concern. who tested the pv wires to read 240dc.. pls go over ur connections again ensure u are not puting positve wire on negative terminals.. a picture of ur connection would be helpful.. ur case just too early

kristien4:
Anyone with experience on growatt inverter. A friend of mine mistakenly did reverse polarity, and heard an explosion, inverter stopped working. I thought it was supposed to have a reverse polarity protection??

lol... u actually get wat u pay for.... someone i was training had this same mistake on srne inverter but notin happened.

Hello fam am interested in Starlink but I want to ask first can I change my DHCP lease time to 5 minutes or lower? Because on mtn, glo, airtel the least they let people change it to is 24hrs so please let me know fam. Appreciate that

y do u need to change ur dhcp lease time oga

We Nigerians praising inverters like Growatt, SRNE etc which are cheap and high frequency shows our shallowness in good solar applications..

Growatt in the west is meant for the poor who can't afford solid inverters and for 80% users they die on them after 18 months or 2 years.

Manufacturers of inverters make it clear to users not to use high frequency inverters for heavy loads. They are not meant for devices with inductive loads like fridge, freezer, pumps, AC. They are not meant for offgrid home applications when you know you'll use the loads. High frequency inverters (without transformers) are for light equipments like lightings, TV, phones, laptop, security cams etc. That's why they are Damn cheaper than low frequency ones. There components are not meant to handle heat for long.

But for us, we will use them with AC, pump, freezer etc and since it's working (of course it'll work), we claim they are the best. But they won't last on the long run.

A low frequency felicity inverter is multiple times better than your highest brand (Deye, Growatt, Tesla) high frequency inverter for offgrid use with heavy loads.

If you are going for offgrid, spend the extra money and get yourself a low frequency transformer based inverter. They are made to withstand heat, dust, heavy loads and harsh environments.

If you need inverter for your office, farm or home, for just light, laptop, TV, printer etc. No need to go for low frequency. Go then for high frequency inverters and save cost

u read wetin u write so? u call deye n srne cheap.....if u know wetin i de take srne inverter eye see u nor go talk this word wen u talk so.. dat u once used a dumb hf inverter doesnt make others useless.

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!

Mrreed , Dam5reey1 , dollarnaira , HeavenlyBang and others.

O check ur camera specs dat is if u re buying good products I think read a voltage from my mumtimer . It was around 14v wen I increases voltage for long range wires recentky

Obnoxious2001:
Good morning house,
Please refer me to where I can buy fuse/fuse holder for solar panels in arena or anywhere within Lagos State.

Thank you 🙏🏾

Check techland

georgee:
For now, Lagos is at Capacity and Starlink is not activating new orders in Lagos

You will have to wait and keep your ears to the ground

how long have u been using the starlink...

good day everyone,

I am new to this aliexpres stuff. and i would be needing all the guidance i can get.. 1550 pages nor be small matter

fuckboys:
it gets hot before the cc cuts off?

does ur previous setup have a smart bms on ur diy battery?

fuckboys:
powmr 60a

4 420 cworth panels connected in 2parallel series 2parallel with is panel voc 31.6v

I just read were ur system has been running perfectly not until I upgraded ur battery to anoda type. Now does this new battery have a smart bms.?

fuckboys:
no my battery didn't even charge at all today with all the sunlight.

I had about 700plus watts around 11am then it kept increasing and crossed 800w before the c. Disconnects and won't charge again.

Please who has experienced this.?

what type of cc are u using. Do mind uploading a pic. State ur pv wattage, qty n mode of connection ( series/parallel)

HeavenlyBang:
Should be around 450k.

not bad but for this 450v dc. I de like 500 oo

HeavenlyBang:
SRNE's 3.3kw. Supports 4000w PV input and 450v VOC.
