Disconnect the AC output and see if your tester is still illuminating. Ensure that the misconnection is not coming from your house wiring before technicians start playing with your inverter.

This test was done but no changes. It's frustrating because asides from the shocking everything else works perfectly

bassdow:
There's defintely leakAge somewhere. A technician could assist with that.

Also you didn't inform us if said inverter is connected to Grid (NEPA / PHCN), neither did you inform us if said system is earthed.

Thanks for your feedback it's connected to the grid but even with grid absent and this is at night it still shocks. The inverter is earthed. From the pv port on the body of the inverter with a tester you will see the AC current flowing. Once the SPD is connected and earthed everything will start shocking. I suspect the current leaks from the pv port to the SPD and to the earthing wire which causes the shock. The house is earthed but the way.

Hello house. I have a 6kw deye hybrid inverter the plastic body that's trending. Anyways the PV port seems to be outputting AC current somehow. If you put your tester in the port it illuminates and if you connect the PV breaker to the SPD and then earth the SPD my inverter and appliances will be shocking. How can I solve this . Is the inverter having factory issues?

bassdow:
Actually, you must not use both PV inputs. You could use just 1 except using a single one wold exceed the max PV input of the inverter.
Don't forget, using both PV inputs is similar to running two sets of solar installations as you need extra PV cables, breakers, etc.

Also insituations such as this, using 600w or 650w solar panels becomes an advantage since Oga landLord dey count panels.

if it help, get started while Oga landlord no dey so He doesn't get to see them all BECAUSE him FIT SHOCK if HE SEEs HOW BIG AND WIDE those panels are. Since 2 of una dey same compound, you suppose don know him movement hence should know whether to start very early in the morning or late in evening and finish up the next morning.

Thanks for the feedback. This helps

Hello everyone. With a 6kw deye inverter with 2 PV input. Can I do 3s on pv1 and another 3s on PV 2 with 550 watt bifacial panels mounted on the roof. Note the landlord won't permit more panels

Hello all. I noticed a battery voltage irregularity between my inverter and the battery a difference of about 0.9v. is this normal?

FerrariBaron:
Ok thanks for the candid advice, tubular erased from my mind lol, i will get the 5kwh 48v lvtopsun lithium battery tomorrow and then get either the lvtopsun 5kva 48v inverter or the Growatt 3.5kva 48v or 5kva 48v inverter.

So please will 4 panels of 550 or 605 watts be okay for the setup? Thank you.

Yayy the lvtopsun gang . It's a great battery and both inverter choices are good as they can both communicate with the battery. Id stick with a 5kva 48v personally Incase your load increases tomorrow

fuckboys:
wow, that can get you mr reeds 16kwh battery.

If i didn't get haisic, it'd definitely be mr reeds.

I would cry after spending that much money and seeing mr reeds price.

I do know the feeling. After seeing his price my mind shake lol however my battery is solid so far. If there is a next time I'll definitely patronizse him. We learn everyday. Lvtopsun brand is great too

TechGeek777:
How much did you get the lvtopsun 10kwh?

1.750

swagifted:
ok... Seems there is no AC on your system

My current ac is a 1hp non inverter AC. As much as I know that my 5kva can power it, I didn't bother adding it

Obnoxious2001:
I think it ought to be able to communicate with the battery.

Select pyl on your inverter and connect to can port of the battery. It ought to work

The inverter doesn't have this setting. Maybe because it's a transformer based hybrid inverter. Either I give up on this venture or I look out for a professional that can assist. It's tiresome

swagifted:
the heatwave for March no be here.... I expect higher usage of AC

You are right. The heatwave is crazy. What I usually do before now is to utilise two fans instead of one. I'll just maintain same protocol 🙂

swagifted:
wait for march next year

Please clarify

Dam5reey:
You have my contact I believe, You need to use RS485 communication protocol. Set RS485 Communication using the screen to Pylon.

Wow what a small world.i didn't know you are on this group as well.It was really nice speaking with you the other day, I appreciate your help and advice cos I was so confused back then. The pylon setting, is it on the battery side?

I want to take this opportunity to appreciate this group in my inverter journey. I love my set up so far. The 10kwh battery is monstrous for my daily usage so much so that I barely consume 10 percent every night with fridge and fan on and the Firman inverter is a champ although I'm still disappointed that it can't communicate via BMS still but I set the parameters as bulk 54.4v and float as 54.0v keeping my battery at 96 percent full charge not 100 though the recommendation is 55.2 bulk and 54.4 float. If anyone is able to communicate Firman with lvtopsun I'd like to hear it as it's important to me. God bless you all for your amazing work

Whenever I connect my Firman inverter to the lvtopsun battery and then turn on gbf BMS function, the inverter stops supplying power instantly all my light goes off unless I turn off the BMS function. I need help resolving this please

mctfopt:
That was fast.


What was the issue?

The inverter is a Firman inverter 5kva 48v transformer based hybrid while the battery is lvtopsun 51.2v 200ah. I simply reset everything by turning off the inverter and battery for a few minutes then turning them back on again. Somehow it resolved the issue. I attached some images. The first is the battery reading from the inverter while the second is from the battery when fully charged. Is this normal

Collione:
Good morning. My inverter just dey show me shege. Anytime I try to change a setting for example if I go into settings and want to change the charge priority or bulk charge value. The moment I change it, it shows an error the reverts the setting.i just changed to default. This means that I can't change anything. What do I do to solve this

This has been resolved

olopan:
Let's reduce the charging voltage to 54.5 , float at 53.5v and leave other settings.⁣

lets see how that goes

Good morning . So sorry for the delayed feedback. Because of the way the battery was placed getting a picture was tricky. Please find attached. Thank you

This is already done. I'll share feedback regarding the value as soon as possible

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

Oh makes sense. My battery isn't currently full as I'm trying to discharge it but I'll share feedback through moment it hits 100 percent again
Thank you

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

Here is the voltage been displayed sir

favouredbymercy:
What is your bulk charging voltage presently? But know that except you are charging to 3.65v per cell, you are not charging up to 100%

My current bulk charge is 55.2v

Hello good afternoon. Is there a way to set my inverter to stop charging my lithium battery at 90 or 95 percent? Kindly advise

olopan:
All is fine from this angle if the battery is a 16s battery.

can you please send a picture of the sticker on the battery? I am having this feeling it's a 15s battery.

@15s the batteries will all be more than full, which is 3.68V instead of sticker of 3.65V, which for long-time usage is pretty bad.

Good morning . So sorry for the delayed feedback. Because of the way the battery was placed getting a picture was tricky. Please find attached. Thank you

Jbond:
When an issue is stressed upon it obviously becomes like a must. If it is my choice to make like you mentioned, i am sure the buy from mr this nd that on almost every of my post wont have been this much to the extent when i ask a question, the reply will be mr this and that can make this for you, buy from mr this and that haba.

Whenever i ask a question, some people here were helpful, while most were more bent on buy from mr this and that and were not even bothered about what i asked even when i took my time to explain why i dont buy things online, then the matter turn to hostility from their subsequent replies, anyway na my fault.

I have been reading your responses and it doesn't tally at all. What I see so far are people who genuinely wish to help you. They have shared their advice and experience but instead of appreciating this you just came out guns blazing. Shitting on their efforts with your negative aura. They had the option to stay quiet but regardless they were more than happy to help. I'm able to get the right set-up thanks to this group. If you knew that this isn't your first rodeo then I believe you are already well equipped. Don't forget, like you we are all human and we should act accordingly ,professionally and with empathy.

olopan:
It's good that you were proactive to turn off power sources.

What voltage was displayed on the battery screen? Please share your inverter parameters/settings for verification, in case there is a mistake.

alarm; full, Power/supply over voltage warning [ it think]:pOVW sOVW, protect mechanism enaged; pOVP

Hello my bro. Thanks for your response. Please find attached the parameters. I appreciate your help

olopan:
Make COU or cut-off Voltage to 48V if it can go that high, but if not, make DTA 49V.

while CU is 55.2 and FLU is 54 ...... This is a more conservative battery parameters for 16s LIFEPO₄ Battery

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

Thank you. I have set up the parameters as suggested. Much appreciated

Valto:
select *USE* or *USER* profile on your firman inverter , then edit the low voltage disconnect to 48v. also edit charge voltage to what your battery manufacturer specified!

Thanks for the feedback unfortunately I can't seem to find Lvd on the manual just the battery lockdown voltage which I'm not sure what it means

olopan:
You need to check the manual for a more in-depth explanation of the lockdown voltage.

But in my own opinion, I believe you should set the lockdown to 48V for safety or precaution.

Thanks for your feedback.Please find the image attached

Hello good morning everyone.im having challenges setting up my battery settings on the inverter. It's a 5kva firman inverter with an lvtopsun battery. For lvtopsun the battery cut off voltage is 48v. Honestly I don't know the meaning of cut off voltage. However for the firman it says the battery lock down voltage is 42v . Is lock down voltage and cut off voltage the same? I don't want a scenario whereby the battery goes lower than it should as the BMS doesn't seem to be communicating
