@ jmaine congratulations on you 2.4kWh set up...

This is one active and very determined follower who has got his system procurement of a 48V 50AH smart Lifepo4 battery module and a 1.5kw 60a MPPT hybrid solar inverter through me and with the help of a very reliable nairalander, he was able to install a very reliable system.

Seriously, his solar harvest is really mind blowing as he gets a harvest of 900W to 1.1KW on a sunny day from a 3×350W solar panels. That is about 90% to over 100% of harvest from a 1.050KW solar array...

When he first contacted me, he had in mind to go for a 24V 100AH battery set up but I requested he go for a 48V. Now, He's system runs flawlessly off grid with a very impressive back up time with his estimated load.

You can't get it wrong if you can follow the basics of this thread. Trust me, it will work very well too with lead acid batteries but don't forget to go for quality battery and double capacity to maintain the 50% threshold for lead acid.

Thanks a lot bro grin.. Your assistance was immeasurable to getting me a very functional system .... cool cool

You will need to provide the wattage of each load and intended run time... Say, how long you want the system to run.

As perceived, am guessing it's for a barbing shop. Please quote me if am right.

Yes.......it's for a barbing shop

Just give me a quote that will power 100 watt load for at least 8 hrs. Per day

Alright:
1. 12V 100AH LFP 150K or 12V 50AH 90K
2. 600w pure sine wave Inverter- 35K
3. 30a mppt CC- 45k
4. 2×300 watts panel- 80k or 2×200 watts panels- 60k
5. Cables, breakers, installation etc... 50k

With this you can be rest assured to run perfectly off grid...

Cool, can you share your cost as well. What inverter did you go for, hybrid? Which charge controller? How much was your 12v 100AH LFP?

Enjoy your lithium!


simydan:
Okay! It's been quite some time now since I set up my system... System was initially grid dependant and did fantastically well in terms of backup and stability.

Now the system is off grid and still going strong... Though raining seasons are always dark days for off grid set up except for set ups with more than enough solar arrays.

Personally, my 520watts solar array is not bad at all for my design, considering that it's a 12V 100A set up and with the battery able to charge in a short time.

Now, the challenges I currently have is the season. With more cloudy days, my solar array is not enough to compensate for it, so I have to still switch to grid in between and sometimes also boost the battery with grid...

Truth be told! My days without power are over with or without grid supply, I still have something to go through the night.

On a sunny day, battery charging and load run complement well with the generated harvest except for days when battery was drained for more than 50% during the night.

Indeed the advantages of going Lifepo4 can not be over emphasised, starting from: 1. DOD and life cycle, 2. Charging rate and discharge rate, 3. Volume and weight...

My set up 12V 100AH Lifepo4 battery can be related to 12V 200AH set up if using a lead acid battery which is better explained below:

Lifepo4 Battery:
12V 100AH = 1200W or 1.2kWh
Which can be discharged up to 80% or 100%(though, discharging to 100% is not advisable)
You'll also need less solar panels to charge a 1.2kWh bank which translate to less cost of solar panels

Lead Acid Battery:
12V 200AH = 2400W or 2.4kWh
Which is highly recommended to discharge at not more than 50%.
But will need more solar panels to charge a 2.4kWh bank which, translate to more cost of solar panels

With high consumption rate, it's always very difficult to stay within the 50% DOD threshold. That's why Lifepo4 should be the preferred choice as it can with stand abuse of up to 100% DOD and still last longer than it's lead acid counterpart.

Trust me, mine has undergo such abuse. Especially the early days of installation during my load test and it's still standing strong. I doubt how many lead acid will survive that within six months.

So far so good! System is over seven months old and battery is still performing very well...

I guess it's time to help someone build a system too... grin grin grin

How much would a system capable of supplying 600W for 8hours/12 hours nonstop cost?

Thanks in advance?

So sorry for the late response... I've been very busy to come online

On the cost estimate and breakdown of setting up a system 600W load with backup time of 8hrs/12hrs:

8HRS SCENARIO:
600W × 8hrs = 4,800Wh (4.8kwh)
So you'll be needing a battery capable of producing 5,500Wh (5.5Kwh) lifepo4.

A 5.5kwh lifepo4 battery will cost you around 650k.

12HRS SCENARIO:
600W × 12hrs = 7,200Wh (7.2kwh)
Battery capable of producing 8kwh will be needed

An 8kwh lifepo4 battery will cost you around 850k.

INVERTER:
For 600W load, you'll be needing an inverter of at most 1.5kw and 2kw for more room to power more load.
Considering either a hybrid inverter or inverter plus charge controller will cost you around
200k to 300k depending on brand and functions.

I can continue with solar panels and the rest but, in a nutshell; you'll needing around 1.2M for 8hrs and 1.5M for 12hrs backup.

NOTE: the system quoted above is an off grid and can run 24hrs but in the case of the system being grid dependent, the cost will come down to 900k and 1.1M respectively...

You can chart me up if you find it difficult to analyze. cheesy cheesy cheesy

Hello everyone!

It's been a very long time since I posted update on my Lifepo4 experience and system update.
Yes! The experience has been very sweet and pleasant as the system served for a year and six months before I finally upgraded it and decommissioned it. Battery, inverter and grid charger was removed and replaced with a 12V 150ah Lifepo4 battery and a 1KW inverter with inbuilt AC Charger.

I'll be reinstalling my new setup to a a standard install.

Old system has been sold and installed with a 2×200W solar panels for a client who is now cruising on... cheesy

If you're wondering where I've been... Well I've been in the renewable energy business and growing in the Lifepo4 experience

Good evening sir, such an educative thread!
Pls I would love to venture into this. I am about acquiring a 2000w/12v pure sine wave inverter with inbuilt charger. I would love to know if it is worth it for just 40 inch tv, ps4 dstv and an inverter fridge. Or should I get a higher capacity inverter Thanks

A 2000W inverter is very ok and have room for more load cheesy

I have a unit of 12V 150AH Lifepo4 battery if you're interested... Going for 180K

It might not have a screen but it has "Preset Charing" variable one can choose from, the only thing being that u can't input a "Custom Setting" suited to a specific use, but one of the presets might do the trick........ Just saying...

He doesn't need the manual, the preset values are written on the right side of the inverter, while the switch is the white thing the middle.

Though it's not clear but u can see the Charge and Floatso if he can get a charge value of 13.8v to 14v depending on the chemistry he's using and a float of 13.5v - 13.8v he should be fine, but remember lithium does not require float and should not be charged to 100% as charging after 13.7v adds little or no capacity to ur cells.....
