A partner wants to go all in on PV installations so I did some research. Felicity solar are the only lower tier solar who have a proper website and proper documentation of all their products. They also have very wide coverage. Across Africa.

Most of these solar products Google searches takes you to jumia and ends there. Or the company ends in Ikeja.

We also went to felicitys main office in okota. They have a workshop filled to overflowing. Whether that is a good sign or not depends on you.

Sir, reading this explanation now contradicts the impression I got from the main post.

If you had not explained with this post, I was tempted to believe that you agreed with him and you were sharing the info with us.

I was almost believing his position, perhaps you should find a way to edit that post so that folks understand that you do not agree with what he said.

contease:
Find attached one of your pictures, thats where I assumed some cables ran over.

But one question please, I noticed my yield is generated and rated in UNIT. And this is not so convenient for me to understand or convert...

earthrealm:
why rely on the random opinion/post of someone , especially a someone who is biased or has vested interest??.

the proper thing to do in situations like this is to use the same internet you used in making this post to google and clear your doubts...the josguy is fond of saying some untruths..as if he is an authority on lithium cell chemistry., forgetting this is the 20th century, we all have access to internet and various online forums

earthrealm:
hahaha, the thing don enter your eye abi, after the test results i uploaded?. its a very handy tool. bought mine direct from china. search on jiji i saw some there, though slightly more expensive

TechGeek777:
I read it bro, he said No Grade A when he bought at that time, he also said there's no grade A anywhere that we can argue till they kingdom come, that all new cells in the market are Grade B & C.

I believe experts here who have actually purchased from you will be in better position to counter Martin's claim of unavailability of grade A cell (i.e if yours is grade A or B).

From recent videos I have watched, they said latest/recent Felicity charge controller are built not to take power from your battery at all, this means you can only use the CC when there's pv available.

Also, when there's cloud The CC will be showing fault mode if the pv is not sufficient to power the CC.

At night the CC WON'T display at all, and from the videos the CC wakes up at about 7am.

So your CC is doing perfectly fine.

The motion is to conserve battery.

All modern Felicity CC now have this feature embedded.

Consider what it means to interrupt 50a of DC current - the contacts must be beefy and huge.

You can find 'battery sensing relays' such as XHM6** series on AliExpress.

What you want to do instead is setup Battery > XHM6** > DC Relay/Contactor and then use the main contacts of that DC Relay/Contactor to interrupt the inverter AC Out. So really you are looking for the XHM6** to detect the battery voltage state and the DC Relay/Contactor to (dis)connect the AC supply to the loads.

In practice you need to consider battery voltage hyteresis and recovery points and also what happens if mains becomes available (ideally want to override the battery voltage based cutoff in the presence of mains or Gen)

Please what is this cost now?

Appguru:
Your number is not on WhatsApp.

What is the cost? Specifications?

mctfopt:
5000ES? How much is it?

viperVIP:
Not awooof!!!
But definitely the best price you can get.

I bought this washing machine last year August and didn't install until September. Bought #370,000.

Letting go due to relocation
#300,000

And 1 week used and decommissioned 1hp LG Dual Inverter Split AC going for 200k. Bought 257,000 during Xmas 2022

I beg to disagree.
One day , at my business, the 5kva inverter kept tripping with overload fault showing. This was an inverter that had no issues with 1.5HP submersible pump and an 1HP AC together on a normal day.
I will switch it back on, check the load (@700w) observe for a while, get back to my office and about 10mins later it will trip again.
Out of frustration,i went to the DB and I started isolating the building, section by section until we found one area that anytime we switch it on, then the inverter trips.
I then called my electrician who came, checked , and could not find the problem. Soon the same issues resurfaced somewhere else .
So we searched socket by socket only to discover a useless phone charger was the culprit. One of my staff, oblivious to my dilemma, wanted to charge her phone . She will plug it, power will go, she will remove the charger use her phone awhile then plug it again when power comes. When i isolated a section of the building, she jejely moved to another part of the building to charge her phone . That day was not funny.
I made sure i destroyed that charger that day before someone go give me heart attack

NiyiOmoIyunade:
I read later where you said your cells are well balanced.

Two possibilites;

Either your BMS parameters were set too conservative for the charge parameters you want to use OR your cells exhibit a larger voltage drift than you have noted under charge or discharge with high currents.

Do you have access to your BMS protection parameters and can you publish/screenshot them here?

When the BMS cuts off charge/discharge, what error message is logged?

In any case you want far more conservative charge settings on your inverter 55.4v absorb and 53.6v float.

The above settings are 3.46v per cell and 3.35v per cell for absorb and float respectively - at a 3.35v per cell float you can be sure no extra current is making it into the cell and no possibility of overcharging it even over the long run.

Observe the battery pack voltage delta (mV difference between highest and lowest cell as well as highest cell voltage) when the inverter is in absorb and also whatever error message is logged when the BMS cuts off power - these will clue you in what is going on and where to direct your efforts.
