I will like to work together with you on this project, most especially the smart setup you have, I have being looking to have a insight to its mechanism

MontyNG:
Interesting... And I'm glad you brought this up.

So in my situation, PHCN is N60 per KW and power is almost 24/7. Even if they take it, it's typically not for more than 2hrs a day. I have to be practising load shedding in my house, just so I can afford it by turning off power from 11/12am till 7pm in the evening. Even with being economical, I'm still using about 800 to 900KW a month which if you do the maths, it's costing over N50k per month

I'm in the middle of building a 5KW system with lithium batteries. and I've calculated the payback period to be 5 to 6years. So for those paying N30 per KW, your payback will be over double. BUt then, the major advantage is I will not have to be so power conscious anymore. Regulating consumption will be a lot easier since I've also made my house completely smart. So I can make "smart rules" to keep consumption optimal always so I would never have to rely on the grid. (Or at most Maybe 5k per month or something)

That's the plan anyway

Satellite TV Technology › Re: Solar Energy, A Complement To FTA by olopan(m): 5:10pm On Jun 12, 2021

This suggested setup is even best for mini SME, since operation are mostly day hours tied.

NiyiOmoIyunade:
One other scenario that I have found to make sense is an ESS or ESS like system for people with 24/7 PHCN supply (estates on IPP or priority service)

Basically you oversize your panels for daytime use and only use the minimum battery size possible. This way you run the house loads off PV during the day and keep battery capacity for self consumption and backup against grid failure.

I have a number of residences on this sort of scheme and all show good results on average 28kwh/d generated from 7kw of panels - at 60naira per kwh this works out to 1,680naira per day or 600k savings per annum from a system that cost under 2million for the solar related components.

True, at least there is fewer points of failure.

Haaa, sorry is their case, at least moving it to the new house covers for both house

SPD with a good earth both AC and the DC type together with good lightning arrestor rocks

The other day someone was arguing that their old house has lightning arrestor, why should they put on the new one. The old house is a bungalow and the new one is a storey building. But of course a road aside electrical "engineer" told them there is no need for one at the new house. I just dey observe

Satellite TV Technology › Re: Solar Energy, A Complement To FTA by olopan(m): 4:48pm On Jun 08, 2021

Good evening Everyone,

Hope our week is up to a great start.

The importance of an SPD can't be over emphasise,
A client called earlier today sounding stressed that her house nearly burnt down, because the washing machine went berserk.

After independent check by three different electricians, it was discovered that there was a surge from the grid and the washing machine which was connected on the grid/heavy consumption panel took the hit.

Our installation is still kicking and performing like it should.

Below are pictures

Satellite TV Technology › Re: Solar Energy, A Complement To FTA by olopan(m): 5:26pm On Jun 06, 2021

The price is fair, for some telecom battery in cabinet this was their quote, but yours I guess is wall mount/power wall

Getting panels locally is quite better, with warranty and any other unseen failure if any

JA panels are Good, new to the market but giving the good names a run, so I'd bet on it.

I believe the advise of DIY build is a good one, many users here run their system on them

1. The battery is direct from suppliers
2. You can add on it the BMS you like for your max. Power demand
3. You get to shave off extra cash and add to other items

Lastly! since you are skeptic, do your research properly, as there are many contributions already ... The time of install is still months away. Take your time and plan carefully.

sethtsadopp:
Thanks very much for your reply. I will reach out to you for further discussion (I am in Abuja though). By the way BSLBATT said they can give me the 20KWh (10KWh x 2 - in parallel) for about $3800. Fair price I think...? I don't think importing panels is worth it though, i have not done my calculations on that well. You mentioned JA.. they good? What do you think about the suggestion someone made on buying cells to assemble. I am particular about the high quality of the entire setup that's why I am skeptical about that.

kindly share your email or contact us via number on signature below, I will like to share with you a more detailed information, documents to fill as to arrive at a precise energy usage and see how we can help bring your ideas to actualization

sethtsadopp:
Well the roofing is not in my hands as it's a mini estate where we just buy. Attached is plan and 3D. The second one is mine. They are still at DPC and project should be ready to deliver by March/April next year so I'm trying to plan ahead. Is it possible to deduce how much Panels each tenant's roof can take from the attached plan/3D?
From a rough estimate each tenants roof apart from the far right apartment excluded should do ~ 11.88KWp /36 JA solar panels each but 40 Panels if others slack

Im interested in knowing. It's a flat hidden roof so i think that's good right?

The flat roof is perfect as the panels layout will allow for the sun to pass over them daily and seasonally

For Load my rough Guess will be
2-3 Interver AC(1.5hp)
2-3 TV
3 standing FANs
1 Water Heater
All lightings
1 Fridge
1 Freezer.

Your loads based on assumptions is roughly 8KW at peak

My plan is to use appliances that are as low energy consuming as possible and this will be factored in as we do any purchase.
So with all these, do you think a 15KWh - 20KWh LiFePO4 would go a long way?

20KWh ESS is preferred

And how much should I budget for?

5.5m without BOS or workmanship etc. ( completely offgrid)

I'd personally like to buy most of the things myself to save cost.

Your items can be bought locally by yourself as you local warranty

I am already in talks with Felicity and BSLBATT. The former is cheaper but I'm concerned about quality as I'm getting divergent views.

Satellite TV Technology › Re: Solar Energy, A Complement To FTA by olopan(m): 5:25am On Jun 04, 2021

The 20 panels is just a start, minimum to charge your batteries alone, considering your loads you will need. More panels. -300W + will be better

If you haven't roof your house yet kindly consider a flat roof this will be better for a solar install.

And plan ahead of time to get your plans scalable and flexible (since your loads, are not properly define yet)

sethtsadopp:
The plan is not off grid. Phcn inclusive.
But I'm also looking at what I'll require to do off grid. If I'm importing myself from China and I can get let's say 10KWh x2 LiFePO4 (connected in parallel) with let's say 20 Panels. Do you think that can sustain an off grid system efficiently and provide 247 Power? Budget by the way is 2.5m - 3m.

I can't really say what load will be yet as we are not in the house yet but at least 3 inverter AC, refrigerator, all lightings, TV and other basic household things will be on it.
What do you guys think?

Used YES, for clients who requested for it or bought already.

Kindly used the search box "thread name while ending your strings with felicity" you can scan through that way

You can try BSLBATT or pylontech, they communicate with victron, growatt and a few other inverter. But pylontech is local so warranty is available locally if not cash restraint

Do your research that learn more in above.

To buttress this

Its best that the critical loads you want to power be used, and assuming you have taken care of your night loads to arrive at the storage

So Loads (watts) x day time usage and add all together

earthrealm:
300 WATTS X 12 PIECES IS 3600WATTS, ASSUME 3HRS OF SUNLIGHT EVERYDAY, so you wud be getting approx 10kwh back from the panels.

the big question is your loads, kindly compute your loads , if your daily avg load is more than 8kwh, then you would be better off getting more panels...

is the setup offgrid?..no phcn charging??

Satellite TV Technology › Re: Solar Energy, A Complement To FTA by olopan(m): 1:53pm On Jun 03, 2021

I get your point now, it's another way to look at it.

ojesymsym:
I don't think so. A normal setup with this his kind of requirement will require hundreds of batteries, but with this model, he can use two even low capacity batteries just to power the inverter that will give the main inverter its reference voltage.

Satellite TV Technology › Re: Solar Energy, A Complement To FTA by olopan(m): 10:36pm On May 26, 2021

True about the simple battery inverter,

But that will require a system of special inverters like victron, SMA to form a mini-grid that the inverters will then feed into to supply loads.

IMO I think it defeats the idea of the Op running away from battery all together.

ojesymsym:
Very nice submission. I wanted to reply earlier but I forgot the Grid tie name and I also could not see my diagram for referencing.

As for the bolded, one workaround is to use another simple battery inverter to play the role odnthe grid for synchronization.

Satellite TV Technology › Re: Solar Energy, A Complement To FTA by olopan(m): 6:56pm On May 26, 2021

Hi

1. How it works is that you are expected to have a steady power supply, then a Grid-tie inverter of say 20KWp or more is installed, the sun comes up and the inverter synchronise with the grid and supplies your loads, the higher your solar production is the lower the grid supplies you and the process is vice versa.
In short at the end of the day your utility bill will reduce.

But

Grid is not steady here, the closest option is an hybrid invester that can work without battery but because your load is high this method will fail without a small sized battery to it or a steady grid supply that will do as stated above.

2. Grid-tie inverter etc. Fronius, SMA, Growatt, Good we, Huawei

Hybrid inverter with independent battery operation
Axpert VM III Variants, Growatt SPH, Phocus etc

3. lipsrsealed

better moni .... Plenty one

Hello everyone, please can you suggest a solar system (including brands of inverter and battery) for me with the following load

Standing fan (92 watt) - If Ox fan ( you can get DC fans of around 20W max each ) to replace this one
Bulbs (5 watt x 8 )
32" TV (60 watt) - If your TV has Eco setting in display setting, then you reduce consumption further
Sound system (60 watt) -
Bruhm freezer (I am not sure of the wattage but on checking the back of the freezer, there is a stated energy consumption of 1.201kwh/24hrs) I will attach a picture of the freezer - 1201Wh/24h = ~51W ( lets say 150W Max.)

Hi,

Good thing you want to go the lithium way,

As par local suppliers ojesky gave a suggestion to this in one of his earlier post, about those who import and couple cells locally, you might want to engage them to get what best suits you as they might give you the freedom of testing ....

Or

You can buy several known brands locally available like Pylontech of different energy variant, BYD, BSLBATT, Dryness and others ... These you get what their spec sheet states.

MontyNG:
What are my options for a 48v LiFePO4 battery. I want to explore local suppliers before I consider importing it myself.

Also, will you be happy for me to test the capacity so make sure the tested capacity is the advertised capacity...
For example, I have witnessed situations where a 10KWh battery (48v/200ah) battery was tested to only have 7KWh

Cheers

It does go off, maybe not immediately

If the switch is toggled off, and solar is present. It cuts the AC output but stays on with fans and LED display on

Or if grid is available too, it stays on to charge and bypass.

This much I know of.

IMO, why not buy from an authorized dealer and get a two year warranty instead of one year you get from jumia and also aftersale support.

We can offer you a fair deal better than what you have on jumia presently with above aforementioned
