the requirement for such, will be mind boggling
5pcs 2hp non inverter ac
1pc 1hp non inverter ac
1pc 1.5hp non inverter ac
that is about 12000 to 15000w here.. unless u are going to replace all AC to inverter variant, if not u are going to need over 18kw of s and atleast 2pcs of 8kw deye..and u must need batteries (lots of it).. with the cost of it, u are better off fueling your gen for now

You can't completely eradicate the need for batteries because of intermittent clouds. Depending on the load, intermittent clouds won't make the hybrid inverter last! Small load might have no issues.
Unless there's guarantee of full sunshine, which is not always possible.

Wow! I still wonder and like to know why folks go this route though. Is it cheaper compared to DIY of higher capacity prismatic lifepo4 cells?

It's far cheaper to acquire the cells, which are of course salvaged. I like my DIY using 18650s as I can afford to lose a few cells to error. But I am much more careful when working with the more expensive LFPs.

zeestone99:


imagine police stop you for road see this one.

During the COVID lockdown, I had someone send me a pack containing about 400 pieces 18650s. The guy was transporting only goods as there is lockdown on movement of people. Police stop the guy for road. The guy gats call me to talk to the police say the officer dey wonder wetin dem be. I angrily spoke with the officer that an elementary student will decipher those objects to likely be batteries with the way they appear. I told him they are meant as replacement packs for medical equipments and so he must not even try anything funny otherwise he will have a lawsuit hanging on his neck. Me wey be say na for my own backyard power supply pack I want take am do.

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 d capacity...
For example, I have witnessed situations where a 10KWh battery (48v/200ah) battery was tested to only have 7KWh

Cheers

I have a 48v 120ah pack booked with a supplier for next month ending. He is still mouthing 650k but I hope to negotiate a better deal when it arrives. The batteries are imported as already packaged battery but he does very effective after sales service. I have a 12v 120ah (from him for 2 years) and 24v 120ah (for 6 months) all working fine.

MontyNG:
Thanks. I've been seeing different brands... I saw pylon tech, felicity, and blue cloud.

Still researching

Do you have s of folks who assemble locally?

Zero 8 Zero 3 Zero 6332 Zero 2

Have had 5 supplies from him till date. 3 units 24v 100ah and two units 12v 100ah. No complaints so far.

As a healthcare worker that also work with resucitative medical equipment as part of the routine, if push comes to shove, I go still prove point. Those life sustaining equipments all have lithium backup power .

Well DC breakers in this case or any type of beaker for that matter basically make or break an electrical circuit.

They also have other purposes.
1. They protect your wiring from any short circuit current that can cause a fire and eventual loss of your wiring or cabling.

2. They protect your equipment, whether it's our inverters, charge controllers, solar s and batteries from short circuit currents that can damage them.

3. They are very useful when it comes to the case of isolation during maintenance of any of the line items, inverters, charge controllers, batteries and solar s.

4. They help to limit the current that can be drawn from the devices they are connected to. This invariably helps to limit the likelihood of damage to those equipment.

5. Breakers are a most have a very professional install. You don't have them or I don't see them in your install and I already know the type of installer who did your install.

So my brother don't be like thoe guys who will say e no mean or you can connect it directly. Please run away from such installer.

I hope this has shed some light on the uses of breaker AC or DC.

What are the usefulness n functions of d breakers sir?

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. better moni .... Plenty one

I’m looking to buy a 24V 7ah lipo battery.

Can anyone recommend?

(Sorry I only need one for my gate)

Also interested in this in case anyone has.

Penuelseun:
You can build one with 18650 cells, 3p7s cells configuration

Built one with 18650s. The batteries went out of balance early and I don't like the hassle of having to disassemble and top balance again. Hope to get a pack with LFP of around 7ah or 20ah per cell.

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 of the grid for synchronization.

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.

YOU ARE LOOKING AT ABOUT 13kw load, 2 to 3 units of 8kw deye shud do the trick, if you stagger the start up of the acs, or have inverter ac, or 4 to 5units of 5.5kw sorotec, the more the merrier.
a 500ah 48v can act as a buffer, to complement, if budget is tight and you are in an area with ample sunlight...say northern nigeria, however x3 of this is recommended. for s since your load is roughly 13kw, you wud need 2 to 4x of this to ensure smooth operation {location dependent}, so lets assume 39kw o, though you could get away with 26kw if you are in northern naija, premuim s o, ie 130 pieces of 300w s , or 90 pieces.

edit : sorotec 5.5kw can take 5kw s, so you would need about 8 units. for 39kw array
deye 8kw can take about 8kw s, since it has 2 mppts, so you need 5 units deye for 39kw array.

1 piece 300w is about 2.5sq meter, so you need real estate of over 300sqm to install the s, a 50ft x 100ft plot of land is about 470sqm to put this in perspective.

330w canadian is about 70k
5.5kw sorotec with batteryless fxn is about 370k
8kw deye is about 1.4m naira

WITH LITHUIM CELLS and their huge 1c to 3c load carrying capability, this kind of setup is better run on a small lifepo4 battery setup, to act as a buffer, with enough controls to turn off load on cloudy days/after 5pm and 20% battery soc

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.

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

We still offer the best design and installation... Anywhere across Nigeria; exception of North and few part of East

Happy Children's day to us all... Lollzzz

If anyone has 280ah or 100ah lifepo4 batteries, kindly quote me. Thanks.

Beautiful!!! This is exactly what i like.
For the first picture, I'd prefer all the breakers, DBs and switches in one sexy Electrical Control (E).

Nice job Sir. I like the fact that your installation is well planned out. Everything in its place. This is what it is..
A clean install, wires are concealed as much as possible.

To every professional installer out there. I greet you all. Let's keep raising the bar. Let's walk the talk.

Hahahah, definitely that your setup needs a central E; plenty components
As for it being sexy, I hope madam would not be forced to yank it out one day and dispose it

I understand some of the inverter ACs don't need anything else except PV power to function. Apparently that's what he's trying to find out.

I don't know of gbm but stay away from Sunfit

sofiscatedmoron:

Pls sunfit and gbm which ia better ,i know they are not the expensive brands

the two of them are scrap. why not save up and buy original battery. cheap battery, will give u limited backup and will definitely fail in less than a year.
