Check the breaker btw the inverter and battery or the cable.. Something is wrong in that part... Have encounter something like that before..

ask4bk:
Hi guys!

This SRNE 10kva inverter has kept my battery charge stuck at 53.2v. That's far from full. There are 6kwh solar panels connected to it. But right now in hot sun, only the sun is carrying the load of the building (as set by user), and battery isn't discharging as we can see on the inverter.

My first guess was the float was set to 53.2v and that's why its like this.

Entering the settings, battery type is set to Li4. I changed it to USER and set bulk and float to 56.0v (thats my personal setting for all my LFP). Yet, nothing changed. Inverter still only getting the sun it needs to run the house and not charging the battery to set 56.0v.

Settings is such that only solar panels runs all loads.
Charging source is set to solar too. Though there's NEPA, the inverter is set to ignore it.

WHAT AM I DOING WRONG?

Battery is cworth 20kwh.

Need help for who understands this SRNE behavior

Contacted you already on this.. Dont know why it was deleted.. If you dont longer use the shunt, abeg i need it.. Kindly sell for me at a reduce fee.. Thanks chief.. Sent a whatsapp message to your contact saw on your bio already.

KudozInteriors:
Sir, you mean taking pictures of the SOC before bedtime and after I woke up right?

I couldn’t do that again as I had light all through the night and I was also advised here to get a shunt which I’ll be getting from @fuckboy here. Will use that to determine exactly what’s happening in the battery as instructed here.

Thank you so much sir.

Good day Guys,

These are my user-defined settings for my LiPo4 battery in my WPM controller:
Rcv (Recovery Charging Voltage) 14.2V
Scv (Constant Charging Voltage) 14.3V
LVD (Low voltage Disconnect) 12.0V
LVR (Low voltage reconnect) 13.7


Pls why is it that once my battery is full, it starts moving from 14.3V to different volts and never below 13.1V . This keeps repeating itself over and over again. Meaning that the controller may be recharging my battery full in a repeating cycle which may likely affect my system in the long run.


Pls is this normal or is my settings not good? Or am I damaging the battery?

Also
There is an uneditable settings that reads “User 1” and is for LiPo4 battery too, but this one stops charging the system once the battery is full. Whereas, I just want it to keep my battery afloat at 13.6V to 13.7V since it’s running load and not just stop charging it since there is still sun.

Pls what am I to do?

Anybody?

BigDickProblems:
Anybody?

please can you rephrase this? I find it hard to understand

oloet:

Sorry, I typed it hurriedly.
What I meant is that, I made those settings (shown below) on my WPM controller in order to charge my LiPo4 battery. But instead of my Battery to stay float (I.e stay around 14.1V or 14.2V for the whole sunny period) when fully charged, it rather starts drifting through different voltages randomly (btwn 14.3V to 13.1V) . For instance, if it’s fully charged for the day at around 14.6V, it quickly drifts to 13.1V, then 13.6V, and then back to 14.6V and keeps repeating that pattern.

My concern here is that, I feel that this process will deteriorate my battery in the long run because I have a feeling that the controller keeps recharging the battery so many times in a day through that process (this is just my thought). Previously when my MPPT controller was working fine, it ensures that the battery stays at its float voltage once it’s full, but the same cannot be said about this WPM. It is worth noting that I carry loads on my battery during this charging periods.

So my question is, is it normal or am I killing the battery without knowing it? Are those settings wrong?

And then, there is this other default settings on this same WPM controller that works fine for LiPo4 battery too, however, the issue here is that once the battery is full, the controller quits charging. Meaning that the remaining sunny period will waste for nothing. In this case, it seems to help the battery but the system won’t last since it’s under load and will not be charged once it’s full through the remaining sunny period to the next morning.


These are the settings:

Rcv (Recovery Charging Voltage) 14.2V
Scv (Constant Charging Voltage) 14.3V
LVD (Low voltage Disconnect) 12.0V
LVR (Low voltage reconnect) 13.7

Thanks in advance chief.

The controller in question is a PWM cc and it is behaving normal since we are in a cloudy season and there is a possibility that your load is more than what it can generate from the sun so it basically pull from the battery when there is cloud cover then comes back recharging the battery when the cloud clears

Update on Luxsun Hybrid Inverters:
I recently had an interaction with their major distributor in Nigeria and he gave a detailed explanation about their products. I thereafter got a 4.2Kva to confirm his claims and I must say that it lived up to expectations, The 4.2kva 24v hybrid inverter powered heavy appliances like electric kettle 2300w, pressing iron, pumping machine, etc but not all at once. The fan doesn’t run at startup until there’s 50% load. They have various capacities like 3.6kva 4.2kva - 24v, 5.5kva, 6.2kva, 8kva - 48v. The 6.2kva and 8kva have parallel models that can be connected together for higher output . The inverters can work with or without batteries, meaning that the inverter can work directly with solar panels to supply your house. They also have batteries but I haven’t tested their batteries and they come with Grade A Cells with 5 years warranty. The inverters come with 1 year warranty and they have a service center in Lagos. I have partnered with them on the hybrid inverters. So, hit me up if you need Luxsun hybrid inverters at discounted prices. They do not accept pay on delivery but be rest assured that you are in safe hands. WhatsApp: 08073872844

How much is 4.2

Actually, there was sunlight yesterday when it started happening. Enough to get it fully charged in a shorter time.

Sorry, I meant PWM 😂

pwm cc works that way, they normally start charging when voltage drops to a certain level and disconnect at full charge.

But mppt charges to full and keeps the battery at full while still powering your appliances. Get yourself an mppt .

This issue with the PWM cc was the reason I got the MPPT, alas it’s stopped working few days ago. So I hope to take it to Alaba or Arena to get it fixed when I have the time. I just have a feeling that this PWM is running more than once charge cycle in a day, which ultimately reduces the lifespan of the battery’s health in the long run.

Juror:
Check your setting [37], what value do you have there ?

This did it oh!
I checked and it was at 52v. The setting option says once the battery is tagged full according to settings, the inverter will stop charging the battery till the battery discharges and gets below a particular voltage point (which was set to 52.0v).
Why will SRNE have such unnecessary complications?
Any way, i set it to 54.8v which unfortunately is the highest it can set to. A minute or so after i applied the setting, for the first time ever the inverter started charging the battery in front of me. The "full" icon disappeared.

What this means is that, the inverter will now charge my battery to 56.0v (charge and float voltage i set it to) and then stop charging and will discharge the battery to 54.8v before picking up again to charge till 56.0v. What a pain? What now happens to the float setting that is at 56.0v? Its now useless?

The below image also shows that when it finally started charging, 3kw is coming from Sun, but only 24A is charging the battery which is around 1300w. Where did other power go to?

Why did people rate SRNE as top inverter when it has all these confusion in it?
Felicity is far better and straight forward than this SRNE.

Pwm : pulse width modulation.

Pushes in current at certain intervals back and forth.

Oh! This explains it then. Thanks Chief!

This back and forth discharge and charging back, doesn’t it have a deteriorating effect on the battery?

NO

Anyone has experience with Cworth 420w panels?

How close is the output compared to its official rating?

Or is there any better alternative at 89k?

The other alternative I saw is Amstrong 440w at 90k; don't know if anyone has heard of that before, so I can't ascertain how good it is.

dollarnaira:
NO

Ok. Thanks Chief 🙌

If you buy the original one. The efficiency is great for CWorth

How can I sell my dead 12v BattlleBorn batteries?

Some of them have only 8ah left in them, 1 or 2 seem completely dead, and the last 2 have about 60-90ah in them, so not quite dead.

Wondering if I should take the completely dead ones to guys that buy car batteries

They’d probably price 15k even they have a BMS in them, chai

Why not open them up and see if you can salvage some cells and the working BMS for a good price in the used market.
