No vex boss...sometimes if you want to go for the first time you might make some mistakes at first if not properly informed buh this mistake will make you wise and enlightened about the solar system so that you can make better decisions moving forward....
Infact I was once in your shoes when I started. I started with a 3.2kva must inverter with a voc of 160v and max current of 15amps. This became a bottleneck for me when I wanted to expand my capacity buh all I later did was to sell the inverter and go for sako 4.2kva with voc 500v,18amps and mppt power of 5,000w so with that I got my panels close to 3,000w now and I am fulfilled with it... Bros just try sell the inverter and keep your panels. no need to get the charge controller cos the money you will use to get a cc just add it to the amount you sell the inverter so you can get a better inverter and enjoy the hybrid life...

I am already putting changing the inverter into consideration. That’s the only reasonable thing in the long run. Thanks

This system is Noisy o, 🤦. It just keep shouting. They just brought it to my lodge; jeeze. It's well.

First check to ensure the load level ain't more than 50%.

Secondly, some of the alarms can be put off from settings EXCEPT when you say NOISY, you meant the FAN

The weekend installations despite the rain..

Location Lekki Lagos

10kva srne inverter

32kwh Deriy lithium batteries

14 no of 620w jinko panels

Supplied and installed by yours truly.

Need your advice on this I am planning for my parents


Double door fridge or Freezer (From 9am to sunset)
55" Tv (Non Smart) 14 Hrs
Decoder ( DSTV) 14 Hrs
Soundbar = 10 Hrs
Lights = 10 pcs ( 4pcs of 20w for 10 Hrs and 6pcs of 15w @ 6 Hrs)
Ceiling Fan = 8 Hrs
Blender Ocassion use
Charging of phones
Miscellaneous

Optional if to be used, then other use will be put of
Pumping of Water (1hp) During the day
Microwave use during the day

The above is what I want to power

1. I plan for a 5kwh Lithium Battery and what Brand?

2. Do I use 24v or 48v Inverter and which good brand?

3. Should I use (inverter + MPPT) or Hybrid inverter? Transformer or Transformerless?

4. How many panels and what brands/capacity

My budget is 2 million, but can slightly be reviewed and not more than 250k

Your usual advice will highly be appreciated

Battery: mrReed has 24v 178ah Eve (4.5kwh) with 100A BMS = 660k

Solar Panels: 4pcs of 600w or 625w = Budget around 150k per solar panel

(Hybrid) inverter of at least 24v 4.2kva = Budget atleast 350k

Charge Controller (MPPT) : Between 100k to 250k

PV Cable: Budget about 15meter length

Battery Breaker: Love to always have dedicated breaker for battery BUT there are those who prefer to skip it when the battery comes with breaker.

Other accessories + PV Cable: Budget around 200k depending on how flashy you want the work to appear like the pictures You see here on Nairaland.

Installation Fees: Discuss that with whomEver is handling said project.

Earthing not inclusive.

NB: Earthing is optional BUT adviced especially when using transformerless inverters.

Feel free to point out errors or if I missed anything. I dey work

This is my generation from 2 535w bifacial panels. As you can see, I am hitting 980w.i even hit 1.05w briefly. My pv voltage didn't go past 75v. The highest I get is 85v that's early morning sef. @hoover420

Hmm, meaning the possibility of my 2 panels hitting 100v is low right? Even my single 535 watt have never cross 44v even on peak sunny days.

FAN yes. I've not even attached any load to it.

Na you dey fear. Connect the 585w

brightk:
this matter don too drag 4 long. Bros install ur panels in parallel.. just find way to provide extra cooling for your inverter

Which kain advice be this one?

You sef shock àbi

12v 125ah and 24v 125ah 280k and 480k respectively with jk 100A 1A active balancer bms.

No battery pack?

cutefy:

There's reason He referred to it as "DIY made easy" .

What @Valto displayed there would work perfectly so long the constituent cells and BMS are of good quality.

We should be able to separate the basics and essentials from superfluous trivialities.

One of ma work laptop (Core i7) lives inside casing of a Blu-ray home theater player (the one that looks like DVD player). I could even decide to leave it naked sef.

And guess what, na for wall I still hang am YET e dey handle projects back to back.

Now this is an honest, honourable and straight forward seller/individual. Nothing hidden about his prices and nothing about being deceptive. Unlike others that don't display their prices and intend to give different buyers different prices. Please, let's take a queue from this and be straightforward. May God continue to bless and uplift you, Mrreed.

hoover420:
The issue is I didn’t snap the back of the Jinko 535 watt I installed before installing it but when I checked for the spec online, this is what I found below

Ignore the naysayers. Series them. I have four 550w+ Jinko panels and I've never even seen 190v from them. Two should be under 95v.

Could be risky but I think you'll be fine. You should also consider using a meter to directly measure the panel voltages at peak irradiation.

This is correct. 555w jinko is 49v voc n like 3-5 volt will be lost to cable.

Hopefully the day someone blows up their expensive gadget, una go take responsibility.

There are decisive decisions that ought to only be taken by those experienced enough; not those looking for ways to avoid paying.
Mind you, whatever we tell one person in here openly automatically could and would be used by others.

I believe he is speaking from practical experience which is valid. It's now left for the person to decide.

Some users have also supported this line of thought from their own practical experience so I guess it's worth giving it a try or not depending on their appetite for risk.

In the end it's all for science.

atimes words should be worded in ways whomever is reading understands what they trying to do. If you observed, I already listed out about 3 or 4 things to expect should both be in series. That way, it's clear to anyOne reading. Either way, we move.

It’s the risk that is giving me concern, I was hoping the inverter will chest the 2 panels with no issues. I’m also surprised because the itel power tank I got for my aunt on CDcare came with 590w jinko panel and the itel Dey chest am well but this my lazy Haisic 1.5kva no fit chest ordinary 2 panels without needing MPPT😌🙂‍↔️

Ok noted.
So that's to say, he has all the above items readily available for sale separately.

The weather has been rainy and cloudy most times today in my location. My inverter reading is as shown in the image.
What should be the performance rating of my system consisting of a 3 pieces 685w panels connected in series to a 4.2kva inverter?

3 years cell warranty

Cycle count of brand new > 280ah are a minimum of 6000 cycle @25 degree.
100-200ah cells are generally shorter 2000-4000.

Please, which would you recommend I go for—the EcoFlow Delta 2 or a regular inverter setup? I'm just worried about ending up with fake batteries.

If you are concerned about Fake batteries, I would assume you have made your choice already (inverter setup in this case). The next thing is to ask the right question about the battery to buy.

what I often tell people is, especially those coming from Nairaland is: if you not sure of a source or brand, just buy from those that sell in here e.g @Valto and @mrReed . I presume they wouldn't wanna easily mess themselves up.

Also, we have said it in here several times that All-In-One setUps rarely are worth it except your useCase requires mobility.
