Thank you, I'm glad you like it.

What's the model of this inverter, is it IVPS5048 or IVPM5048?

@@peterakoh3432 IVPL5048

@@diyfalke okay, can you please do a video on IVPS3524 or/and IVPM3548?

Yes, they are not honest with their claim of 5kwh, but for the price I think it's still a good deal.

@@diyfalke Do not know how much you payed for it, i bought 16x CATL FFH3D3 (same cells that are in your Felicity) and paeyd 590€. Add over this a BMS (100€ = 2A active balancing) => 690€.

Thank you so much 😀

I'm glad you like it, Check out my WhatsApp link in the about tab of my channel. Na gode.

Hi, I set my bulk and float voltages to 56.4v, Low cut off voltage to 48.8v.

@@diyfalke Nice. Thank you sir for the video

I attempted to charge the pack to 57.6v, but as the voltage hit 57 sometimes jump to even 60v, the charge controller will cut off with an error 04, which means battery voltage too high. Then it will reconnect and attempt to charge to 57.6v again. The only two logical explanation i have are either the MPPT is not good or 57.6v is too high for the packe.

I tried 2 other MPPT (both Felicity) reduce the charging voltage to 56.8, 56.4v, 56v, 55.6v, and even 55.2v, the same thing happened. Until I assume the pack is 15s, and take the Max for cell to 3.65v which gives 54.75v, the battery charge in a typical way, and the soc bar indicates fully charge. So until I open the inside, I think the battery is 15s, and you can only charge 16s to 57.6v i.e 3.6v per cell.

@@diyfalke One cell is rising faster then the others, triggering the BMS single cell overvoltage.

@@diyfalke Being too long at the peak voltage or lower voltage is something the BMS will not allow. Also, it could be the software aspect. We did one installation last year we had error 04 for the 5 kW Inverter (IVEM) and the 170 Ah / 48V at panel voltages higher than 270 V (for 450 V maximum). We reported and were sent a software upgrade for the Inverters. Once we upgraded the software, the error was no longer there. I see it as a good move for the BMS regulation as you can still build charge at the other voltages.

@@diyfalke thank you ive seen the video

I think buying battery from Alibaba is cheaper than buying in Nigeria here

@@odeywilliams7596 not necessarily, this $700 on Alibaba without shipping, it will defend on how much dollar exchange and how you get it.

@@diyfalke ok

I'm not sure about the ambient temperature in your location, as it relates to you AirCon power consumption, but I think 5hours is really good. In my location, it runs 1.5hp Aircon, TV and some lights for about 4hrs give or take.

Sure, why?

Let's say 1hp consumes average of 920w each hour, the actual capacity of the battery is 4400Wh, at 80% DOD, the usable capacity is 3520Wh, this means, when fully charged this battery can safely run 1hp Air-condition for 4 hours. The battery can deliver 2200W continuously (@0.5c) and a surge of 4400W (@1C) for few seconds.

Check out this video by Will Prowse on sizing your solar system kzfaq.info/get/bejne/irByesWmy8vcdYE.html

You are recommended to discharge dry cell battery to 50% DOD to get the most cycles out of it, so A 5KWH lithium battery discharge to 80% DOD is equivalent to 3.3NR of 200ah Lead Acid battery discharge to 50% DOD.

800ah because you are taking 50% of dry cell which 400ah is 4kw so to get 4kw you get 800ah dry cell and get 4kw from it ,4kw in the sense that the 5kw is to be taking out 4kw from it

I have not, I'm hoping to get my hand on one soon. How can one tell grade A cells from B? The only information I heard is A+ cells passes all the test required to be used in EV.

@@diyfalke I opened one yesterday and I found a barcode with B letter , send your email I send you the picture

@@diyfalke the LPBA84170 is the biggest lie in 2022 . it is not A+

@@marketingtherapyoffcial diyfalke@gmail.com

I'm sorry you are having difficulty with your setup, however I do not work with Felicity solar, nor in anyway affiliated to them. But i will be more than happy to help you in any way I can.

It can serve you upto 3000 cycles @80% DOD before the capacity decays to 80%

@@diyfalke They are given for 2000 cycles and aging give 80% capacity after 11 years. (CATL FFH3D3)

@@davidniquot6423 I believe if a manufacturer can lie about the capacity, they can be lying about other things, and I only see the datasheet of CATL FFH3DS, which has >=3500 cycle life.

@@diyfalke trust me if they use catl cells in those, it will cost way more

I have had this for only 10 weeks, so far there no single issue, the main issue many had with Felicity batteries is the overrated capacity. They have another series made for European customers, these could definitely have greater build quality, more accurate capacity rating and probably better BMS due to the low temperature in the winter.

@@diyfalke given your experience, would you advise someone to go with Felicity for a 75KVA buildout or look elsewhere for other batteries

@@caniceonuoha I take it you mean 75KWH battery bank. If so, I will say it depends on the budget and location of use. Compared to other brands like Pylontech, EG4, and BattleBorn etc, Felicity cost a fraction of these brands, the Felicity LPBF series have greater value for money, I will hardly recommend the LPBR series to anyone. The LPBA series are in the same league with EG4 in the price range, amongst the two, I will always go for EG4. Even the Felicity LPBF series have two or more class, one promising >=3000 cycle, the other 6000 Cycle.

@@diyfalke thank you. I didn’t know that EG4 is available in Nigeria.

@@diyfalke hi I sent you mail

I assumed the inverter doesn't have inbuilt AC charger, or the AC charger current of the inverter is small. you can consider buying a 48v AC charger, check out these video by Will Prowse. kzfaq.info/get/bejne/m7epq7Zpm96wmJs.html

​@@diyfalke thank you so much

​@DIY Solar Power with Falke Amazing. Thank you very much. Pls quick question, how would I connect it so I do not need to unplug my current inverter to the battery. Thanks once again

@@mexossai7982 I'm afraid you must disconnect the inverter, the chargeverter comes with Seamless Crimp (SC) Lug. What worries you about disconnecting the inverter? You can chat me up, my WhatsApp is on the about tab.

sorry, your question is not clear.

Inverter goes off when you put it on. It goes of after a minute even wen de is no load ,and if you put panel it dose not show either

What's wrong with you

To calculate backup time for 5KWH battery, you first decide the depth of discharge (or usable capacity) say Felicity recommend 80% DOD, which means the usable capacity is 5000Wh * 0.8 = 4000Wh. This means you can run a load of 4000w for an hour. 2. If the load of 550w is including the inverter no load consumption fine, else add the no load power consumption to the load. This can be found in the inverter manual, or you can measure it with clamp meter. 3. Divide the total load(including no load consumption) by the efficiency of the inverter. Assuming 90% efficiency, that is 550w/0.9 = 611w. 4. Divide the usable capacity of the battery by the the load result calcilated in 3 above. That is 4000Wh/611w = 6.55h or 6h 33minutes. Summary. The Felicity 5KWH battery can safely run a load of 550w for 6h33min.
