The case may be shocking. ...paint is a sort of insulator.

This leakage is coming from your inverter.

Fix inverter and issue disappears.

jFrankNorfleet:
I've installed and started using it since Sunday afternoon

This was the final installation

1. 6KVA Deye hybrid inverter

2. 16KWH Deye lithium battery

3. Jinko Bifacial 725W panel. 8 pcs


It's been an awesome experience so far as I'm yet to use generator since I switched and the lowest battery percentage I've closed with was around 12:30am at night which was 48%.

Now I don't panic when there's no light or when my light trips off, which it did this morning.
I'd even say I've only used light to charge the inverter this previous night, aside that it's all been the panel. The panel almost always, even at slightly cloudy times, give more power than the shop consumes.

Thanks house for all the advice and I'd like to hear more advice in terms of maintenance, what to do and what not to do.

Glocal1:
Congratulations.
Is this a 24v or 48v setup?

fuckboys:
chief what can cause this? The inverter and battery is earthed. Inverter is a 4.2kva Haisic 24v

Battery has a metal case, the case isn’t shocking only the terminal.

bassdow:
Even without you mentioning the inverter, I already knew na transformerless inverter.

tlDr: issue probably from your inverter.

You said earthing is done. I for say the earthing no work well, but since battery casing and inverter casing no dey shock, means the earthing dey at least work. E still fit be the issue o, but na technician wey get direct access to the setup fit talk for sure.

To try debug this yourSelf to narrow down issue, and be 300% sure it's the inverter, you need to work in stages:

• Stage 1 (NEPA): First disConnect NEPA from the inverter (if e dey connected, else skip this). Normally from the point labelled AC IN. Wait small, then test if e still dey shock or if tester still dey light up. If the shock still dey, leave NEPA disconnected and move to Stage 2.

• Stage 2 (Solar): Disconnect the solar panels. No just OFF the breaker Ooo—comot the wires from the breaker completely. Wait small again, then test if the shock or tester light still dey.

• Stage 3 (AC Output): Make sure you completely disConnect the AC Output of the inverter. That point where power dey comot from inverter go house (usually labeled AC OUT).

• Stage 4 (Battery): If e still dey shock after all this, this one fit sound stewpid but disconnect the batteries completely. Then test those battery terminals coming from the inverter. If tester still light up, then we are 300% sure say na the inverter dey misbehave.

Frankly, 9 times out of 10, na inverter be issue. But I suggest all these steps make you no go waste money and time dey treat wrong symptom.

PS: you failed to inform us if said issue started recently or been there right from when it was installed

fuckboys:
I don't think it has been like that since onset, I routinely tighten all terminals and clean dust.

So I decided to do it on that Faithfull day and it got a shock, so I took out my tester and saw that.

dollarnaira:
Earth any terminal of the battery or inverter separately.
Get a single copper wire, attach it to a rod and dig this into a wet soil.

fuckboys:
I just did further troubleshooting and found out that when I put the change over to neutral the terminals stop shocking even with the inverter still on.

Is it coming from the house or something?

Kingadex60:
pls I want to learn, if no wet soil, having like a dry land.

Do one need to wet daily for the earthing to function properly

bassdow:
I don play this your trick before but got the shock I deserved because inverter carry light give earth and innocent me go use hand touch the cable

BUT

Going by his latest response, seems the inverter has no short; probably the normal transformerLess wahala.

BUT other than using Tester , me for say make e first use multiMeter check voltage make e no ge be say na full voltage or something beyond 100v.

When customers refer to shock, some go even call static tingle as shock and you go mistake am for something serious.

That Tester fit dey read high Voltage with little or no current and that could come from even solar panels.


Hope say una dey see why Me personally respect mySelf dey use Transformer based inverter.

e get another nairalander wey be say almost all the bulbs and chargers for him house don blow finish until we found out say one of the batteries was bad.

dollarnaira:
Troubleshoot with the above first.

fuckboys:
I earthed the inverter terminals to the earth of the inverter and it stopped. No current again to the battery terminals.

twinskenny:
am putting up this setup for sale. the client is upgrading the system

location is oshodi

the items will be available on sunday (we are installing the upgraded system then)

mono panels 300w or 250w 10 pieces

3.5kva inverter

4 no of tubular batteries (they still hold charges)

Charge controllers
'
other accessories

price is 750k for all

bassdow:
throw more light please. which of the inverter's terminal did you earth ?

Make confusion no confuse me

fuckboys:
I ran a wire from the negative battery terminal of the inverter to the earth terminal of the inverter.

Valentinooo:
Look for other part of the body of the battery to connect the earth. Don't use the terminals direct.

You can lose one of the bolts used for screwing that back cover, wind the wire round it and screw it back tightly.

fuckboys:
only the battery terminals are shocking not the battery casing.

brightk:
I don't think this is gud idea... U don't ground supply terminals

fuckboys:
only the battery terminals are shocking not the battery case.

Earthing the case didn’t stop the terminals from shocking.

bassdow:
don't have to be wet daily. The land is hardly ever completely dry especially down to about 4ft even if the top soil is very dry.

E get reason trees survive even during dry season. If you dig ground, you go see say inside inside still wet to some extent.

Though positioning the earth rod around location wey dey receive some amount of moisture even if it's once a week or month not bad.

hoodboy:
Please anyone with idea how much local mounting rail (Nigeria) is sold and where I can get it from?

bassdow:
why not check markets / shops around you Or ask any shop that sells Solar items around you.

meanWhile, you ought to tell us your location so those in Damaturu wouldn't bother themselves unnecessarily

Eaglepixel:
What you did is called Neutral to earth bonding,
You’re correct just that it should have been done on a changeover and you still need to deactivate the settings on the inverter change it to off.
Lose the bottom cover and locate N-E lose it, because you will likely see it with a small metal connected.

Just search for the inverter manual settings on how to deactivate Neutral to earth bonding. This is also done in A.C transformer reason why N-E reading is below 5v.


The issue is called Neutral floating.
