Battery bank: 460AH
INVERTER/CC: Growatt es5000
PV: 9, 450w (Original) ERA panels and 5, 450w (fake) Canadian Solar panels. 2p7s.

The inverter low state consumption is about 70w

I knew your battery bank is large.....
70w idle power consumption for 5kva inverter is much. I sold my old 3kva Felicity transformer based inverter because of high idle power. My current 5kva inverter consume max idle power of 40w.
Please, how do you know your era pv is original and Canadian pv is fake?
Please, share your experience..... I'm using 9 pcs of 450w era pv too.

TechGeek777:
Okay, tbb is strong and it's Riio Series is about 380k + for 3kva Non-hybrid

3kva 24v hybrid is 500k plus now.
I bought the 12v 1.2kva 85k last week.

Justice629:
I totally agree with the quote, the highest SOC since beginning of July to date is 60% and that occurred once this month even with a 6300w pv.

With a terrible power generation this month am still rocking 100% off grid with no downtime but with a serious energy management .

My current DOD (8%) now will be fantasy to PB users while truest to lifepo4 shine without breaking a sweat. My DOD and SOC this month fluctuates between 5% to 40% and this will probably be bad for PB batteries.

Attached also is today's forecast which is terrible for my current DOD😭 how do I navigate through this🤦🏾‍♂️

I guess your battery bank is up to 28,600kwh.....
What type of inverter are you using, is it hybrid?
What type of pv?
This is the time to know the drawing/sucking capacity of various tier 1 and 2 panels.
This is the time to know also how good our charge controllers are. They are some that will not wake up early no matter how we configure our pv. There are some that will wake up very early and sleep late.
Again, some people will still appreciate the low idle power consumption of their inverters this season.
The key word here is "management"

Justice629:
Worst solar day, and yet pumping water for the tenants

Raining all day with dark clouds

Lithium battery is really good for those that are staying in the southern Nigeria.
You hardly see this kind of weather in the northern part of Nigeria.
If we are to check the cost of over sizing pv for lead acid battery to be able to effectively charge it in this season, then it may be better to spend less switching to lithium with an average pv installation while managing partial charging of the lifepo4 battery through out this season.
I was seriously worried on how I would charge my lead acid battery to float, at least every two days in this season with 4kw pv on the roof. Most times, I would switched off everything in the house just to pump the available power generated by the pv into the battery. The most painful of it all was when my battery enter absorption, the amps pumping into my batteries was reduced drastically and batteries would not be floated that day. At night, I would discharge it again and the new process would begin the following day. Equalisation was even out of it....
Today, I'm very relaxed and we manage our loads with whatever % we see in the battery bank.
This is our gain with lifepo4 battery especially for people like us running off-grid system, who has made up minds not to switch on generator again at home.

For those that have received deed of gift on landed property, do you submit only the deed of gift given to you or you add it with the photocopy of the land document and submit?
I'm just asking to know if there is need to submit the land document together with the deed of gift.
Thanks

What if it is inverter AC or those mini mobile AC, please? (Pix attached)

Is it okay to use?

If all goes well, within 2 months, I can get another tubular battery

Though the capacity of this item is not stated, it's not still advisable.
Go for 48v system if you intend to power AC and budget the minimum of 3m for it.

oweniwe:
1 hp AC, 250-500L Freezer, Bed side fridge, 4 fans, TV, Decoder, Lights... That's all

8am - 8pm daily

But due to situation on ground, no AC and Deep freezer usage until I get another 220ah battery

I suggest you call a good installer to design a system that will power the stated loads but unfortunately you may not be able to afford the cost/bills.
When you add the second 12v 220ah battery to the first one, please don't use it with your AC, even during the day.
Again, it will not be good for you to add another 12v 220ah lead acid battery after six months.

Who gets 1.5kw 12v PowMr hybrid inverter for sale?

Machiny:
am interested in this contribution because mine is still around 300watt. But my emphasis is on a freezer of 100w, tv of 45w, rechargeable fan of 45w, with phones. My questions are can an inverter power the freezer directly through solar? Can a 12v set work effectively as a 24v? Whts the benefit over the other? Can price tag required materials to achieve 160ah proposed on lifepo4.

If your total loads is below 500w, go for 12v system.
System design is based on loads to be powered.
24v system is more expensive than the 12v system and will power more loads than the 12v system.

waleayeni1:
Solar generals, I greet una specially. The numbers you guys mention for solar setup dey make my heart beat fast @Valto and the rest are killing it around here: calling big big numbers like say na chicken change. God dey. My question is; for person like us wey no too hold bar, what's the best and most durable non lithium battery we could buy that would serve us well? I am looking at 2 batteries of 12v 230ah capacity. Also what's the best budget charge controller to use with the batteries. I like DIY systems and I really want to do it myself. My load is not much, a less than 100W fridge, 75W tv, other nominal loads like phones and laptop. I need una experience make I no go use head jam wall

Since you are on tight budget, why not going for 12v 160ah lifepo4 battery about 2kwh battery bank.
This will be cheaper for you than going for 2 pcs of 12v 230ah lead acid battery.
Work on loads management by powering your fridge/other important loads during the day. By 9 or 10pm bedtime, your tv may be put off.
The remaining minor loads like fans and lightnings will take over till 7am.
You should try and buy rechargeable standing fan or qasa ceiling fan with 5 steps speed/remote control.

TechGeek777:
Those using Standalone inverter with separate CC to charge they LiFePO4 battery, what happens when the battery is fully charged and you still have Load connected and solar is available.

1. Will the battery keeps charging just to supply power to the load?

2. Will the BMS shutdown inflow of power from the CC and thereby supplying the load directly from the battery?


I know that with hybrid you can set power to be used from solar alone, but I am considering how possible it will be to use the power from pv(when available) and not touch you battery when you have a floated battery in a standalone point of view.

I'm also waiting for comprehensive explanation on this.
For lead acid (tubular) battery that I've been using with standalone morningstar Mppt CC..... In bulk stage charging, more amps are pump into the battery.
In absorption stage charging, very limited amps of about 20 to 25 are going into the battery irrespective of how large the pv capacity is.
In float stage, the amps are further reduce to about 5 while maintaining the float stage till charging source is removed or sun is gone.

I'll like to know how it works in lifepo4 battery because I may dedicate standalone CC to my lifepo4 battery bank.

bbeckky:
ok bro, but 1.2kva inverter is fine right

Go for 3kw 48v or 3.5kva 48v or 5kva 48v Inverter

bbeckky:
Thank you so much, God bless u. Pls, what capacity can power the pumping machine?

Go for 48v 230ah battery.

bbeckky:
Thanks again bro. Pls can this setup power a 1hp pumping machine. I attached pic of the spec

It's always good to ask questions especially when you don't have much idea about something.
The answer to your question is NO.
If you're planning to use pumping machine, then you'll go for a bigger system and that will also involve a bigger amount of money.

TechGeek777:
It's 545w @ 148,500 from Gennex, not as boldly stated.

Your friend must definitely enter one chance, if he goes against your suggestion.

I saw 149k for 550w Jinko pv when I checked their website today.
Do you know any good 550w tier 2 pv and 3kw 24v hybrid inverter with higher Vds I could recommend for him?

My friend wants to purchase 4 pcs of canadian pv 300w at 65k in alaba market.
I wanted him to buy 2 pcs of 550w Jinko pv from Gennex at 149k each, buy 3kva 24v hybrid inverter with higher Vds and go for 2s1p.
I hope he won't fall into the hands of stiker pasters.

TechGeek777:
I am sure you are better off with 475w Jinko from Gennex.

Check this -> energymallDOTng/product/era-solar-450w-half-cut-mono-solar-panel/

It's addition Sir.
I needed one or two to add to the existing ones.

Please, where can I buy 450w era pv?

Nexuspulse:
Profit margin way too high. 26k, 53k & 58k respectively. Abeg make we dey pity ourselves for this country.

I don't think this is necessary as we do reach out for price deduction.....

Kiekie, do you still have 450w era pv?
How much is it Sir?

TechGeek777:
The wattage consumption of the freezer is enormous, do you mind sharing the model and size of freezer?

Are you sure those batteries are okay?

220ah * 48v = 10,560w / 2(i.e 50%) 5,280w

With 5280w of usage I see no reason why it Should give mere 8hrs just to charge phones and use bulbs (100ah LiFePO4 battery should be able to give you 10 hrs just to charge phone and with good energy bulbs).

Unless you are able to state the wattage of those bulbs and how many they are in numbers & also state the idle consumption of your inverter, I don't think you will get a satisfactory response.

Which battery chemistry do you use, tubular or AGM?

Also, do your batteries float daily?

Boss in this part of the country with a porous/non linear system, theory works for about 90% and practical works for about 10%.
Your calculation works for linear system where virtually everything is up to the standard, it works also for diy lifepo4 cells coupling.
We kept preaching the gospel of battery capacity test in this forum but unfortunately some people don't have time for it
Let the guy carry out capacity test and let's see if the 220ah battery will be up to 180ah.
When I was using 4 pcs of 12v 230ah tubular batteries, I derated them to about 160ah each and discharged 30% from them. I later sold them after two years of usage and I'm very sure the batteries will serve him for the nex 3 to 4 years if my usage method is applied.
Going solar route require a lot of planning and awareness. Anyone that can't give lead acid battery baby sitter should move to lifepo4 battery. The price different is very small......
Again, day time loads of about 1kw with the stated pv array may not have been given enough room for the effective charging of those batteries which I'm suspecting to be tubular.
I suggest he charges those batteries to float first and allow them to rest for 1 to 2 hours before testing each of them to be sure they are all in good condition.

abuzz33:
I would have bought from you but I like transparent dealers so have gone with Felicity lifepo4. Keep hiding your prices and calling what you do business.

It's his business Sir.
He has that power of decision..... Lol
Buying from him is a choice and not buying from him is also a choice.

Valto:
apologies for that, but his post was very harsh though. i also buy from people online. and i don't wait around for quoted prices, i simply DM, discuss and get what i want.. this is Nigeria,price of cells and accessories can go up or go down at anytime. also some people prefer a 100A, 120A, 150A and 200A smart bms or normal hardware bms,, 125A breaker or without breaker, so am i going to list 6 different prices for one item?
i repeat, serious buyers normally DM and discuss and order what they want.

Sorry to say this, most times it helps.
Most of us are helping our friends and love ones to secure these items.
I personally do call you to ask for price of some items for them and at times network fluctuation doesn't allow me to get you on time but if there is price list, I would only do the calculation or snap it and send to them and then call you for final purchase.

mctfopt:
A friend bought his Growatt inverter from the US and has had no problems. Are they selling defective units in Nigeria?

It's interesting that you learned about Growatt from the not-so-technical YouTuber Poz. You should also check out Will Prowse. He's an excellent resource for information on Growatt inverters

Most of these products designed for Nigeria market from China are substandard and they are making huge profits from them compared with what they manufacture for other countries with a very strict regulatory bodies.
That's why those that are buying lifepo4 cells and assemble them stand a better chance of enjoying their batteries more than those going for already coupled battery from the Chinese companies.
Some of our Ogas like Niyi who are not on budget usually select countries like USA to buy coupled products from.

olopan:
I believe that zeestone sells something of that nature, it is a DIN rail mounted device that allows you to set the max. wattage to be drawn also current to be drawn. Maybe sintolord might be of help here

I will check it.
Thanks sir

I'm planning to give my cousin 100w power max. I need to install something like current limiter that will stop them from consuming above the given watts.
Please, what device will handle this work perfectly for me?
Something that will trip off at my end if they attempt to plug appliances above 100w.
His house is opposite mine and they have been disturbing us with phone charging too much.
100w would be enough for phone charging and perhaps 3w bulbs 3-4pcs for night and 1 energy efficient fan.

3kva 24v prag hybrid inverter
3kva 24v must hybrid inverter
3kva 24v iPower plus hybrid inverter.
Please which of these three are more reliable and compatible with lifepo4 battery.

I was actually looking for 3kw and not 3kva. Recommendations for another good brand is needed. Felicity is out of the picture.

I may need up to three units.

Penuelseun:
Yes it does

Thanks

Does PowMr Mppt charge controller have editable profile that could effectively charge tubular batteries?

justcallmenuel:
