easyyoke:
Hello, experts in the house. I intend to go fully offgrid. But I am worried this may not be fully feasible for me during raining season. If there is no PHCN atall for two straight days and there is no sun for two straight days, I enter panic mode immediately reducing all loads to the barest minimum. Three days cloudy day and my battery dies. I intend to supplement with using generator to charge my battery. One day full charge of my battery can carry me for two to three days without sun or grid. I have heard most inverters dont play nice with petrol generators. Is there anybody using Petrol generator to supplement sun or grid. How can I get this to work for me without spoiling my inverter. I have a 15kwhr battery and a 5kw spf growatt inverter.

Get a good generator with minimum twice the capacity of your inverter and with a clean output.

seunlayi:
Its a lithium battery, that's why I am worried whenever I noticed this. It's happening again now, it's almost 30v and when it gets to around 31v the battery will stop taking the current and controller will display 39.9v

Get a better charge controller before your controller damages your inverter, do not even consider Felicity, their MPPT has similar issue. You may try SRNE's latest PWM if you're on a budget or even their Fan-cooled MPPT that is usually cheaper.

AndroBlaze:
I still remember being corrected by people on here that inverters that can run on variable battery voltage inputs do exist, though I am still yet to see one sha.

Check for Anern DU4200 inverter, it has the dual voltage feature.

HeavenlyBang:
The question literally asks how to identify them, which is what I said.

Yeah, it's transformerless vs transformer-based, but how does that help a layman identify them?



The MPPT is seperate in the first place. You can argue semantics anyhow you want, the information I provided is how to best identify them.

What you stated is not a valid means of identification or distinction.
There are HFs that have Voc under 150V, in fact majority of the earlier HF solar inverters have this, even some latest models have that.
I am surprised you are even doubling down on your earlier post.

This is not about arguing semantics.

fuckboys:
What he described is characteristics of HF $ LF inverters and he's right.

It is not, Low Frequency and High Frequency is not about PV Voc range.

There are even LF inverters that have Voc higher than 150V and as much as 600V Voc.

FerrariBaron:
Please i keep seeing HF and LF inverters. How will someone know which products are HF or LF inverters?

Or hybrid inverters are not classified as either HF or LF?

Here's the simplest distinction
LF is "transformer inverter"
HF is "transformerless inverter"

HeavenlyBang:
For hybrids, MPPT voltage range.

LF hybrid inverters will generally have max VOC of under 150v, while HF will go up to 450-500v.

What you described is not LF / HF

Collione:
Thanks so much. When the battery got full a red triangle kept flashing and here is some info displayed in the pictures. Kindly advise. Had to turn off all power sources incase

The value I want to see is the particular voltage in this screenshot

Collione:
Here is the voltage been displayed sir

I want to see that particular voltage it was showing the day it went into protection.
I think you recorded it but the screenshot you shared wasn't very clear.

Knowing what that voltage was would give an hint if the battery and inverter's reading are in sync or there's a difference.

Collione:

What was the voltage being shown by the battery here ?
I couldn't see it clearly.

ask4bk:
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.

Many of these brands need to make their documentation easy to understand.

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

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

AndroBlaze:
He's commenting about the inverters not the battery backup.

I must admit I find it surprising someone in their personal capacity, in this day and age, would need to switch on so much simultaneously....he must have either a really big mansion or a large family.

The inverters is what I mentioned their capacities too, they should be 10kW each.

HeavenlyBang:
This is 24kw of inverters, I suppose? Why exactly does a residential building need this much power.

If I am not mistaken, That's 40kW not 24kW.

Pnutmillionaire:
Thanks brother
There's an option on the deye inverter called "Bms_err_stop", it was unchecked by default, I checked the box this morning. This night the inverter tripped the house light off again but instead of the usual "f56 error: DC_VoltLow_fault", it threw an "f58 error: bms_communication_fault" which seems to be the origin of the voltlow fault.
So Im thinking perhaps there is an issue with the bms's firmware or the bms itself.

Point of note, the battery is 16kwh and has not been loaded with >800w when there's no sufficient pv

Why not test it without the communication ?
Set the charge values manually.

What model of Deye is it ?

KudozInteriors:
If this FCCPC will work, I’ll be glad o. I’m already on their site. Let me write to them. I want to use every means available to me.

Thank you sir.

You can also report to Lagos state consumer protection agency LASGCOPA, you can search for their number or visit their office.

KudozInteriors:
He has parked out from where he was staying. I don’t know where he stays now but I know the area.

Still brainstorming on other options as well as opening up the battery too just that I don’t know where opening the battery leads me to. The battery is definitely compromised.

Book session with Dam5reey to open the battery.

Thereafter you can write to FCCPC to handle the case for you. I doubt you will spend anything using them compared to the police route, though their action may not be immediate but I see no hurry.

Dam5reey1:
The Guy rugged am oo 14.3KWh Deriy

Na really rugged.

Dam5reey1:
Out for delivery

12V 100AH Taico - 220k
12V 100A LVTOPSUN - 230k

is that a 14kWh battery on the bike ?!

KudozInteriors:
Good morning great minds

Thanks to everyone once again for last time.

I’m back with reports as I’ve connected the shunt to the battery and loaded it all through last night. These were the final readings:

1st and 2nd picture: Shunt reading at the start and at the end of the experiment respectively.

3rd and 4th picture: Battery reading at the start and end of the experiment respectively.

The performance data is really abysmal but the battery at 25.4V is far from 0%, that's about 16% left.

Personally I would've preferred you opened the battery yourself except the warranty sticker has not been broken. So you can see whatever concoction that is inside or you even take it to Sako themselves to open.
Thereafter make sure those culpable are held to book.

KudozInteriors:
Thanks so much for this.
I’m already thinking of arresting the installer tomorrow like this. I’m just confused like this.

I feel terrible right now.

Don't arrest anyone yet.

Try to take the battery to Sako yourself, point out the discrepancies to them and tell them to disassemble the battery in your presence.

KudozInteriors:
This is the label on the battery.
It’s says 5120wh

Hmm this is serious.

This casing looks like the one for Li-Sun 51.2V 5kWh

25.6V 5kWh Li wall is quite different from this.

and your display is telling us this is a 25.6V 100Ah

there's been some crisscross somewhere.

KudozInteriors:
Please this RSOC here showing 85%, does it mean the percentage of battery remaining?

Please share a picture of the battery label.

HeavenlyBang:
Umm, don't these numbers mean this is a 2.5kwh battery?

This looks like a 100ah 24v battery?

Very true, that means they're delivering their capacity.

The next question is, why does the owner think they're rated for 5kWh?

KudozInteriors:
Please this RSOC here showing 85%, does it mean the percentage of battery remaining?

Yes.

and FCC... full capacity is 100Ah and you have 84.92Ah currently available, which means your panels may have not been able to charge your battery full since morning.

olatade:
Good afternoon house



My inverter setup is as follows: a 3.5kVA inverter with two Luminous tubular batteries. I have three 555W Jinko solar panels connected in parallel to an old 60A Modern Felicity charge controller. 6mm copper wire from the panels to the charge controller. However, the cables(6mm) from the charge controller to the batteries tend to get warm, and sometimes even hot. What could be causing this, and is there any solution?

Get a thicker cable.

KudozInteriors:
Good day great minds

Thanks for all the contributions and instructions since morning. God bless you all.🙏🏼

I just got home and snapped the SOC as requested. The panels are charging it currently. These are the pictures of what I saw there. Please is anything wrong with the battery?

You've don well, the battery is/has been charging but obviously it won't reach 100%.

Next thing you have to do is this, just when you're about to go to bed, take same set of pictures you just took and send them here, when you wake up in the morning too, do the same.
Hopefully that should give us some more data to analyze.

Dam5reey1:
So the house was in Black out..
His needs to pay attention to details.
This batteries in questions is not anyhow batteries, it has communication as well as Screens that shows Current consumption but he decided to use Bars when BMS shows SOC in it's screen.
He should show what the Batteries current displays and at what percentages.

Exactly
