Good day my people can anyone reconfigure 2set of 5kws of 24v Felicity Lithium battery to 48v?

Emyfine08
Well done boss so what size of sumo can someone used to run 700ft only in day time on Soler only and the draw current and the size of the pv?

Submersible/sumo pump installed 700ft down is likely going to be a monster, above 10hp.

Lemme assume 10hp which is about 8kw, you would need minimum 250% of this in s to ensure the sumo works decently during the day.
Ie 20kw s, say 35 pieces of 600w s.



also some brands/models of sumo dont have startup surge, . Such models would be best for you in this scenario. I have a 250watts sumo/submersible pump like that, zero start up surge, infact you can pump water with i my nebo gen or 500w inverter.but its limited to 120ft water head/depth.
Am unsure if such design is available for higher wattage sumo


Its best you get the exact consumption or rating of the pump to guide in the calculations.
If funds are a constraint, you can consider powering such a pump in battery less mode, with just s and inverter.

Till you confirm the rating of the pump, all this would be in realm of conjecture

jonescosmo:


They are actually 35mm x 2 on each pole. I used single 35mm initially but they were heating up while charging at 240A.
So instead of linking the 2 batteries, I let each battery travel to the inverter on its own. Now the heating is gone.

I have the breakers to worry about now. It's rated 125A and I'm pumping 240A through it. Instead of it to trip, it's just there heating up.

hello sir interested in your 5kva felicity inverter very urgent..

The whatsapp link u kept on ur profile isn't work

How do I reach u!

Good morning all,

Novice here that will need your help. I recently installed a setup for my home using a Famicare I think 3 or 5kva.

2 tubular 220ah battery and 2 300w and 4 180w s, with an Mppt Charge Controller. All were brand new.

All installation was carried out by an installer so forgive me if I don't know the right specifications.

The issue here are
1. The inverter battery charge light never goes off. Always blinking since in1stallation.

When the battery bar (four bar) voltage is always at 13.5-13.7v .

2. Major issue, the battery doesn't last more than 5 hours. Usage is not that much at least I have never gone beyond 25% load capacity since installation but within 4-6 many hours of use it starts beeping.

Note nothing heavy is on the system. Four fans, One TV and lights.

Please what is the solution to this as this setup cost quite a lot and isn't meeting my expectations.

What type of:
Fan --- ox or ceiling fan?
Tv---- Led, lcd or box?
Light--- spiral or led?

If a 1.5hp pump is drawing 1.8kw for its regular run then it is either ancient or inefficient or falsely labelled (should have a higher hp value stuck on for the duty cycle it can actually handle)


Dear Niyi, the power consumption of submersible pumpd Earthrealm stated is what most of us see everyday. My 1.5 HP gulps btw 1700w to 1800w. Initially, power consumption was btw 2000w to 2200w. I had to double the size of the cable to 5mm2 before power consumption dropped to 1700w to 1800w. You should also know this, most of us buy the Chinese pumps. The efficiency of this categories of pumps are low. Only very few people buy the very expensive pumps made in or Italy. Just the same way, only very few people buy Victron. So Oga Niyi, the power consumption Earthrealm mentioned a while back is the reality of most of us.

Good morning everyone. I intend getting a 7.5kva or 10kva felicity hybrid inverter and 8 flooded battery coupled with 12 380watts solar s. What brand of battery is recommended for use, and also is there a recommended seller in the house that has these items?

drizzypat:
thing now is I don't know who can help fix it

The backup inverter. How much can I get a smaller one for now .

Fairly used or relatively low price will do

I must have missed the gist. What happened and what do you need to repair sir.

You might want to increase your pv. It also depends on how well you will discharge your batteries. You can use any battery type depending on application and how it suits your budget.

What are your loads

Morning.

As for the felicity hybrid inverter. I saw a thread sometime ago where @jonescosmo put for sale his 5kw hybrid felicity inverter (x3) as he was upgrading his solar setup. You may want to get in touch with him for finer details.

Personally I would recommend an AGM, Lithium ion or Lifepo4. Experts here have spoken highly of Quanta AGM battery. @valto supplies good lifepo4 batteries. Other can advise on good battery distributors.

No. But you can Felicity engineers if the bms in their batteries allows that.

My Oga,

Yes, I am well aware of this reality - apologies as I was being rather mean/insensitive.

At some point, a discussion about how one could safely and reliably make a lean system power relatively large loads assisted by solar got hijacked by side engagements about the efficiency and energy consumption of various pumps and the superiority of LFP to lead acid.

My apologies again please.

Confirm that your batteries absorb properly.
Second 4 fans, tv, lighting and miscellaneous is no small load on 2 batteries.
Lastly you should consider the self consumption of your inverter.

Please what do you mean by PV? I currently have a 3.5kva inverter with two dry cell batteries and four solar s installed but I intend going off grid hence why I'm upgrading my setup. Loads will be majorly two LG dual inverter AC of 1hp each, thermocool freezer of about 150watts, LG inverter fridge of about 130watts, two LG inverter TVs and led lights of say 20 at a time with each being 5w. Also Microwave to be put on Alone after Putting off the ACs

Am late to the party and I'm seeing victron flying everywhere. When you talk of victron in our renewable energy world, it's like rolls royce in automobile industry.
You can't buy a car for over 400million naira and not expect the best of engineering. Also if you don't have that moni to spill, u cant Kee yourself , Look for your kia and Toyotas

Thank you very much, lithium battery price would be too much to handle at this current time so I might have to go with the AGM, please any idea on the prices?

It should be doable, if you are ready to void the felicity waranty.
You just need a new bms, a new metal case..chikena.
The 2 felicity packs will be gutted/dismantled, cells top balanced and put in a new case, a suitably sized bms installed, and voila you have a 48v lithium pack

Good day house, Please can anyone with information on the difference between these three Felicity 5kva 48v inverter models help enlighten me.

FL-IVPM5048
FL-IVPS5048
FL-IVEM5048

Thanks for your response. On the absorption how will I do that?

The fans are low consumption fans 45w - 75 w, lights are led lights, TV is not always on. My major suspect is the battery never full issue. I saw another vta2008 had the same issue.

Previously I used two dry cell batteries with a sine wave inverter and it went for 10 hours on the same load. So I doubt the issue is load.

The batteries are charged with both electricity and solar s.

NiyiOmoIyunade will love your view and that of others on this.

IVPM models are low frequency transformer based inverters with MPPT - the IVPM5048 should have a 120a MPPT bundled in

IVPS models are low frequency transformer based inverters - NO MPPT

IVEM models are high frequency hybrid inverters. The current iterations can do PV voltage up to 450v DC.

People colloquially call the high frequency inverters 'transformerless' but technically that is not the case.

You welcome. I think between 150k -220k depending on capacity but dont quote me .

Please check with @Kieki1 or any other member that sells or recommends a direct source distributor, he should be in a better position to tell you prices as he deals with solar batteries, inverters etc.

Best wishes.

stay away from those cheap 120k to 170k 200ah AGM. a very good 200ah AGM battery price is now equivalent to lithium battery.
e.g, original 200ah amaron quanta is now around 220 to 230k, fullriver and ritar are all above 200k.
my 12v 135ah lifepo4 lithium is almost the same price. and u can deplete to 90%

bigrovar:


That is a very old inverter from a company that used to be one of the biggest inverter brands from India (before they went out of business) I was actually my first ever inverter and I had nothing but good things to say about it. It is very simple so expect no bells and whistles. It however gets the job done without issues.

The things I liked about it include
* Efficiency. I had the 1.6kva inverter and it used just 24w when idle. This is relatively low for an inverter of its class
* I can charge the battery when the inverter is off, I found this feature quite neat as it allowed the inverter to charge the battery even when it is powered off, It can also through from the grid to inverter load when it is off.
* it has temperature-controlled charging. The inverter has a temperature probe that can be attached to a battery and used for configuring temperature-adjusted charging. A very rare feature for an inverter of that class
* The inverter has built-in "UPS" mode. This feature allows it to have very fast transfer times between grid and battery backup (not more than 10 ms). This becomes useful if you have desktop computers or other sensitive equipment behind your inverter, it ensures you don't face a restart during power transfer from the grid to inverter battery backup or vis visa.
* The inverter is generally very rugged. I used it and sold it off and the person who go it also used for for a very long time. It is a very simple inverter but is built to last.

The limitations of the inverter include
* Slow charging and generally limited charge capabilities. the inverter can only do 15A charging and the charge voltage and time is not adjustable. It has some presets like AGM and Tubular.
* Limited surge capability. The ability to use the inverter with inductive loads is very limited. The inverter can not be able to meet the surge requirement of large appliances like freezers and water pump
* Not so good-looking. The inverter is not the most good looking especially when compared to Chinese inverters. It has no wall mount option for example.

Thanks sir

hi

With respect to someone using lithium which will u suggest to use..

Hello so today my tech engr came in.

He said it's the inverter he turned it on and there was a spark sound from the inverter itself, he then suggested to have it fixed that it'll be favorable

My only issue now is will the cost to have it fixed not be up to half the must inverter itself?he said it's a board thing.

What do suggest guys..

Spend to fix or result to getting another ...

I'm talking on a long TERM basis

I am completely off grid!
