I'm not the owner of said inverter as it belongs to my bro. Just asked him and he said the yellow indicator stops blinking but still remains on, likewise the battery indicator stops the filling animation on the display. It'll be wise to invest on a battery monitor (with a shunt) to stop second guessing.

Thanks a lot man. Will find time to go and raise complaint at the shop where I bought it since they gave me 1 year warranty. That blinking light is the only thing stressing me out.

Well this is how it is now.

A very neat installation and equipment architecture you've got. Though the entire space appears quite small sha (just thinking about all the plenty heat generated, as well as, the gas emissions from those tubular gang).

I can only imagine in my mind, how relieved and joyful that your stressed out generator in the picture is, in its new role as a mounting stool.

However, just know this for free... the power distribution company in your area will not be very happy with you at all. Because, that prepaid meter in your house will not be generating enough revenue for them again.

Well, in all of this, a big thumps up to you Jones.

Chichilas:
Hello house.

I have this slightly used 48v 2.5kw lithium battery for sale. Battery was coupled and sold to me by the Jos guy when my lead acid batteries suddenly died on me. I ordered a lithium park from china but couldn’t be in darkness while waiting so bought this from the Jos guy to use temporarily as a stop gap. Battery is well made, contains a bms and a heltec balancer. Perfect for small systems. I used it for 2.5 months and decommissioned as soon as my batteries arrived from china. You can contact me if you have further questions. Price is 350k

I also have a 48v Felicity transformer based inverter. Inverter board was destroyed by thunder and I had it replaced by a generic board. Still works perfectly. 130k give away.

Also available are 2 used 48v ha02 lead acid balancers going for 25k each.

8 battery rack also available. I can send anywhere in Nigeria as the rack can be dismantled. Going for 40k

My WhatsApp is 08038896842, you can reach out. Zeestone is my installer and has been to my house many times so can vouch for my integrity.

Pictures below.

Thank you house.

48v lithium battery sold.

Battery rack, ha02 balancer and Felicity inverter still available.

I believe that blinking light comes on when the battery is in absorb mode because the same thing happens in my tbh inverter. If I may ask, what is the capacity of your battery and for how long does the blinking light stay on?

Just for people who might want to setup something similar, the space is 8ft x 8ft sha. I have ordered a 16Inch Extraction Fan from the USA, The fan is Temperature and Humidity Controlled, also has a mobile App for remote control and mmonitoring.

The "Tubular Gang" are meant to be decommisioned and sold off after fully testing the Lithium batteries and their capabilities. Those Tubular Batteries is going to be replaced by a 3rd 9.5KW Lithium Battery and the 2x 5KW inverters will be put in Parallel Mode (Teste this method already though) Or I would simply grab another inverter with 2 MMPT input Strings for my 10x 540W Panels and 8x 350W Panels, Felicity now has a New Model that has 2 MPPT Inputs , this:

and this:
https://www.felicitysolar.com/best-48v-5kw-hybrid-grid-tie-pure-sine-wave-inverter-for-home_p128.html

Hehehehe, That my Generator is a 3Phase 6.5Kva Birtoli Gen and was retired since almost 4 years now by my 4 Years old former Inverter (3Kva iPowerPlus) Which I have now installed for my mom in Lagos (Picture Attached Below). So the small Gen is just there rusting out.

This new setup is aimed at retiring my 20kva Mikano Generator for good. And ofcourse Nepa People are not happy with me ooo. They came last week to inspect my meter and I showed them the panels on the roof. Hehehehe. I told them the I had to sum up the monthly 100k I used to recharge for 3yrs and yet the electricity will still not be available when you need it most times. so i decided to demote Nepa Supply on my Priority list and go for solar energy.
The two Genertaors might be auctioned out after a year of fully testing this my potential off grid Installation.

Congratulations Boss. Your pocket am sure has not been smiling lately but in the end its worth it for the peace of mind and stability of electricity supply that you will enjoy. You really went all out for this . You have covered all the bases for a neat install with all the protections included. Now that the priority installs are done, maybe you might consider other functionalities like publishing your stats to Emoncms or Pvoutput where our senior Egbons like Bigbrovar, Ojeysky, Barezzi have been killing it with their solar production stats

Were you able to carry out capacity test on these Felicity batteries?
Some of us are still doubting the capacity, wondering where Felicity is sourcing its cells from that makes 15kwh 1.6m or thereabouts.
Even with letter B QR code of Eve cells (A-), it's still very hard to couple and sell at that price.
You've really invested cash in RE.
Congratulations.

Nna no vex for me abeg. I don come again. Help me buzz your brother.

The fans are always on and somewhat loud, is that normal?

The only time they go off is when the inverter is switched off and there's no NEPA.

E be like say I go blog post for new Famicare inverter buyers when I'm done sorting out my issues with the inverter

samir101ng:


Your welcome .

Glad to hear it worked out. You can add a wifi dongle to the inverter for remote monitoring & communication later as an upgrade.

Try and get those Yingli panels from their office since its been confirmed to be in stock. You won't regret it. Hope you get a very good 100A BMS for your LifeP04 batteries. Don't forget to use rated breakers and surge protection in the install of your inverter. Also, let it be properly grounded and connected to your earth system to avoid surge/lightning strikes that can damage your system.

Hi boss, is this BMS brand okay?

I'm planning to buy all this small stuffs before getting the panels next month.

Fan comes on during charging and off in float, also comes on on high loads. My Axpert inverter does same too. I guess most Chinese inverters do same while charging. If your light is blinking, then most likely your inverter has not entered float. You might be depleting your batteries more thereby requiring long charge times hence while your fan is always on. For lead acid batteries don't go below 50% infact I've gone slightly below 65% once in my 4 years of using my tubular batteries and batteries are still flawless. So end point is get a battery monitor to know your battery soc and properly monitor your inverter charging profile and battery well being properly

The Capacity Test is actually the next thing on my todo list, I have populated a list of Battery Meters, DC Shunts, Sensors etc. for this purpose but they are yet to arrive.

I wouldn't mind buying from some of us here though if anyone has Battery Capacity Test Meters please reply with details.

For the QR Code, I don't wand to disassemble the batteries now because of the Warrantee (10Yrs), I know I will find my way to get this info eventually. I made friends @ Felicity both in China and Nigeria and I will definitely run into an open cage one day and get my info on the cells.

I must say that the Felicity Lithium Batteries have performed excellently well with the Load I have on it as compared to the Tubular batteries.
These are 48V-57.6V Design. and the minimum voltage I have gotten so far is 52V after 14hrs (6pm-8AM) with remaining power @ 35%

isangjohnson:

Please, let us know as soon as the capacity test is completed.

Of course Boss
I haven't done the capacity test yet if this is what you are asking.

If not, I have 2 Units of 9.5KW Felicity Battery, adding a 3rd unit soon due to addition of loads recently. Disregard the Tubular Batteries because they are being decommissioned.

That's the problem as load causes voltage drop so it's not a reliable way to check for battery state of charge(soc) . For you to get the soc all load and charging should be disconnected and battery resting for some time. I found the below to be close to what I'm getting with my battery monitor

So I can set 48.5v as low voltage cut off on the hybrid inverter I believe?

Congrats brother. I just want to comment on a little section of the post. Will comment on the rest later.

I have learnt that once a week or once a month you should still run the generator, not so much to use it, but so it does not go bad. Now that I am partially dependent on my inverters, I can go months without running the generator but whenever I try to run it, it doesn't come on until after several tries.

I read nasty things about Tubular batteries on the DIYsolarforum.

I still don't believe after what I have read that they belong indoors, but then I am a solar newbie.

Here are the excerpts.

It seems if one can afford it, one should not do Tubular.

I am posting because the usual installation pattern is inverter on top, tubular batteries below. As several pictures on this sub-forum and online indicate

Daly BMS is a good BMS brand and affordable. Another two brands you can check out also is Jiabaida & Jikon BMS both on AliExpress. They come with active balancers and are in use by many DIY enthusiasts on this thread. I however prefer the Jiabaida (JBD) for its use by multiple OEMS like OverKill BMS https://overkillsolar.com/ who customize it further and update the software.

Thanks Bros.
For your Gen, the same thing was happening to mine until I Changed the Control Panel and rewired the Gen with a DSE7320 MKII
https://www.deepseaelectronics.com/genset/auto-mains-utility-failure-control-modules/dse7320-mkii
and a DSE9130 12 volt 5 amp Compact Battery Charger
https://www.deepseaelectronics.com/power/12-volt-battery-chargers/dse9130

I programmed and scheduled the Gen to run itself without giving output for 15 Minutes every Sunday 8am. While the function of the Battery Charger is to keep the Gen Battery alive using AC supply from my domestic connection.

About what you read of Tubular Batteries, yes they evaporate into the air within the installation corner and should not be inhaled. If you have money, go for Lithium but be sure you respect Lithium principles because the can be very dangerous too if wrongly deployed or configured.

Inverters that are Wall mountable will be on the and those that are table top are kept on top of a table-like rack mostly on top of the Battery rack to keep things close and compact.

You can always see professional advice here if you run into glitches with your DIY projects.

Cheers.

So I can set 48.5v as low voltage cut off on the hybrid inverter I believe?

You can, but pray you don't have incessant tripping off by the inverter. This is because if your batteries are say 80% and you put a heavy load like a microwave, the inverter voltage might drop to your low voltage disconnect and trip off

At this point, you can get a small EV, like the Nissan Leaf, to fully utilize this setup.

I swear it's too much ooo. Most times I check the Inverters I see each of them frying about 4.5Kw from the 2 strings of panels respectively. So I know the system is capable of delivering that much power so I feel bad when there is nothing more to power up in the house to consume the excesses.

Thank you boss. This Jiabaida (JBD) BMS looks complex (but interesting) to me compared to Daly. What's really confusing is the number of wires that came with it. The Daly for example came with the right amount of cable mouth (8s = 8 pieces of cable to attach to the battery) which seems pretty straightforward. I am expecting a 24v battery setup which will use a BMS 8s, where will the rest of the wires go assuming I'm using a JDB BMS? I have attached a screenshot of the wire that I'm referring to.

Additionally, does the balancer that comes with the JBD means I won't need to worry about my Cells not having a balanced charge out of the box, meaning that once I use JBD bms, it will balance them automatically, and I won't have to worry about looking to balance the cells before setting them up?

Kindly enlighten me on these... Thanks!

Edited: Also boss, from the little research I've carried out, I want to ask if it's necessary to top balance the lifepo4 cells when you buy them from 3.2v to let's say 3.5-3.6v?
Would the output performance became worse overtime if I didn't?

Because I noticed that to top balance a battery, you need a power source that needs to run for hours (if not days depending on the cell capacity you have), set to a certain amps, and I noticed that this needs to be done by someone that knows what they are doing in order not to fry the battery by overcharging them.

Some videos I watched even claimed that the active top balancer that comes with bms is not entirely reliable...

@ojesky
@valto
Kindly help share your thoughts on this.

coldcandy:

how do you compare 10.5kwh of tubulars with 19kwh of lifepo4?

They are not being compared boss, But if I may comapre them, I have a 5KVA Inverter, 8 Units of 220Ah Tubular (21Kah) setup in my Office. Backing up just my Server, Switches and CCTV. A total load of about 2.5Kw max and the Battery Backup Time is nothing near that of these Lithium Batteries with a wooping load of almost 7kw.

In all honesty. Tubular batteries did well during their regime but the game has changed. Lithium has taken over.
As we speak several combination of Lithiums are in production (See Table) but lets just stay on LiFePo4 for now.
