3 pieces of 300w
Not one 300w

Dam5reey:
Hmmm, this is not efficient, 300watts panel is connected to PWM CC on a 12V system.

That's nice.

I really like the mppt CC built in the inverter
It shows the wattage and amps the solar is charging at and even shows that of AC input together.
Most inverter out there don't give those details.
Also i noticed it has a fast charging speed for AC.

Drgreatone:
2kva12v. Using it for about 3 weeks now. Its same make wit sunfield which i have running for about 6mths now in my ogas place. There's a 4.2kva version also in a friend's pharmacy.

12v

Dam5reey:
PWM Controller?
Is this a 24V system?

.

Idk
I seriously just feel the one i had has a factory defect
I actually like the inverter, i just pray it keeps up and not give issues in the future

TechGeek777:
Does it mean the inbuilt CC in sms sunmate is not good?

I dey use one corner eye dey look this SMS Sunmate Inverter, but don't have enough users to share they experience on it

Thanks to everyone input to my case earlier
I've gone to install an external CC and the series issue has stopped. Everything is fine now.

Just a quick question
How many amps should a 300*3 mono solar panels produce at peak Sun?

So basically
There's no implications to it if it's left that way?

Trippledots:
I have experienced this thing before, when I was managing a PWM inverter as well. But I noticed the house had poor grounding and the inverter and cc itself didn't have a grounding point.

I noticed if I used a cable to connect to the battery and touch my window burglary, which is like partially grounding the PV, the issue reduced, but was still there just less worrisome.

So I'd wager you should confirm the grounding of your hybrid inverter (or ground the battery head, but I'm not sure if that is electrically safe to do).

I'm still there
Gonna fix the new CC tomorrow morning

What's a busbars?

Obnoxious2001:
Are you still there?
What type of db is there?
Check your busbars in the DB.

Guys isn't this weird?
Cos this is my first time seeing this

It didn't work

Obnoxious2001:
Keep me posted.

I'll give it a try tomorrow

If I understand you well
You mean i should swap the wire that's connected to L to N
And VIce Versa

Obnoxious2001:
Yes.

For the Inverter output right?

Obnoxious2001:
There is leakages in the circuit.
An easy fix is to swap your output (L to N and N to L)

Lol
Every expenses after installation has been covered by me, all the troubleshooting, calling electirician and what not has been covered by me. I'd be going to akure tomorrow from Lagos to install another charge controller, money for charge controller and even my tfare which is roughly 20k is all covered from my pocket. Not tell me I'm not doing enough. Nobody wants to make an installation and then start having issues with it, not the installer not the customer.
The actual reason I won't be going for the mppt cc out of my pocket is because right from the beginning... The CC i included on the quotation was a 60a PWM CC not Mppt to save cost. But because i was going to get a 2kva Karter 12v inverter which i was unable to get in the market, and customer insisted he didn't want anything below 2kva, we came to an agreement to get this hybrid inverter for him which was kind of a + for him cos of the inbuilt Mppt cc (on paper)..
So why i go carry my own money buy Mppt?
He's definately not interested in spending any money.. all he wants is for me to come and get it fixed.

I'm just trying to please my customer..

samir101ng:
You see this statement. This is what gets me angry. This is why a lot of Nigerians have such a high distrust for anything inverter/solar and Kazeem installers adding to it with poor service. After quoting and charging a client for labor and materials. You install a product that suddenly develops a fault NOT due to any user error, and yet are unwilling to go the extra mile to support the client. Most installers have this attitude of once i install anything for a client and i collect my money they can go to hell. Not knowing that an installation is an entry point to continuous patronage and good will that can last for years and bring even bigger rewards down the line. As an installer, you should ensure that materials you buy are original and comes with guarantee/warranty from the suppliers for their products. No client wants to hear that they are on their own when it comes repairs and warranty claims. As e dey pain you now to remove money to resolve this issue, so did it pain the client to cough out his hard earned money to pay you for a quality service. In business some days you win some days you lose. But always try to treat your customers better and try to resolve their issues.

👍

sharks776:
As a professional installer, you just don't look at the monetary amount/value alone. Consider the customers satisfaction also. Trust me, both you and the customer will be more happier in the future if you deliver a more satisfactory work today. That's how you get more recommendations.

Lmao brr😂

kobarney:
There is nothing informative about this video. The camera was too close to the bike, I was really hoping to see the full shape. Abi you thief am?

That's about 80k.
I'll be getting the CC out of my own pocket. That's too much for me to cover

odimbannamdi:
Get Powmr CC. It is true MPPT and much less than 100k

SMS sunmate Hybrid inverter

Obnoxious2001:
What product

This part has been eliminated already

This issue only happen on the inverter
Gen and phcn works fine, even while the inverter is connected and charging with PV. If nepa light come or generator is on
Everything is okay until u switch to inverter.
i.e. The problem is only present when pv is changing and inveter is working. Doesn't happen on nepa or gen

brightk:
this ur issue only happens when the pv breaker is on. Please disconnect all devices both inverter, wires, pv, battery and all breakers like u never installed anything Start troubleshooting with a gen set then move to phcn. If none of these isssyes occur on both sides then reinstall your devices one ny one. First only inverter and battery since its hybrid) then try to charge from phcn or gen.observe if the issue occurs there.

Na wetin we no know b this o

This issue only occurs when the PV is changing, once sun goes off or i off PV breaker
Everything is okay

Obnoxious2001:
Wait is the cc in the inverter faulty.

That fault is an electrical fault not an inverter problem.

Only on inverter
Gen and nepa is fine

Obnoxious2001:
Does it happen on Nepa?
Does all the lights in the house still glow even after you off it?

They said it's Mppt on paper

I spoke to their office i bought the inverter from. After so much do this do that, they finally asked me to bring the inverter in for them to check up. Maybe na replacement e need or what not. Inverter wey i just installed for Akure o. Client is really pissed now, he said i should just come install a secondary charge controller and we should just move past the issue because inverter fit reach their office mak dem say nothing do am and they send it back again.
My issue is if I'm to install another CC, na pwm e go be cos I'm not about to spend over 100k on a CC wey client no go pay for and if the one built in with the inverter is really Mppt then it will work better than the PWM.
I just dey confused like this

dollarnaira:
Obviously your inverter is msw.
Reason I like dem individual. Not bc of ur case oo, i no like hybrid one bit.
Now, it is difficult to confirm the fault- in built inverter, charger, or cc. One major reason i detest hybrid is how to confirm if the cc is pwm or mppt.

Yes

noobody:
Comes with box and charger?

Tested the battery current with a normal electricity AC tester (not multimeter).
It was showing power which was weird.
DC no suppose dey conduct electricity.

Even the solar panel pole from the inverter conducted electricity on the tester.

Also. I have tried creating a socket outpout just to plug phone to it and test. The whole issue still persists, so it's not like something is wrong with the house wiring.

dollarnaira:
Your inverter is "likely" a modified sine wave.

Check if a regular fan hums when working.

Plug the phone or laptop directly to the Inverter and check.

If the floor is tiled, touch battery terminals with your bare hands for electrical "shock" when powered on.

Lastly, get a tester for current on battery terminals.

Seires issue.
Like all the socket in the house still have smalls
Current even when the socket is off, and it's making devices like phone and laptop misbehave when plgged in while using.
I discovered this only happens when solar is charging, (the inverter is an hybrid) it works well if Solar breaker is off or it's night already . I know getting an external charge controller will fix the issue. But I'd like to get to the root of this issue at hand

dollarnaira:
What exactly is the issue in the first place?

Okay.. but the thing is, i ran a separate socket to the inverter output (not connected to the house) and it was still doing the same thing. Now I'm confused something is actually wrong with the inverter itself

Jefferyzz:
Yh. At times it's neutral, at times earth, check YouTube for various fix n apply those u see there, 1 go work

Earth wire? Or whatever it's called

Trippledots:
Seems like a grounding issue.

I later did some troubleshooting about this issue and I discovered this only occur when the solar panels are connected. If i turn of the solar breaker this series issue doesn't occur, but when i turn it on back it occur again.
The inverter is an Hybrid inverter so the solar is connected to it.
I can't say the power coming from the solar is too much cos they are just 3* 300w 36v solar panels.
I've tried contacting the technician at SMS sunmate inverter, I'm yet to get a positive feedback from them. The only solution i have at hand now is to result to an external charge controller which is something I don't wanna do. But it's looking like i don't have much choice here.

JoeSef0:
What could be the issue here
I noticed whenever I'm on inverter and I'm using my phone while plugged in, the phone touch start malfunctioning, even my laptop trackpad and touch also malfunction when plugged in on inverter.. this doesn't happen on gen or NEPA.
Abeg who don experience this thing b4

PS:
I just noticed if i turn off extension socket, the socket light doesn't go off totally until i unplug the socket

It's a one week old installation,

brightk:
hmmm. Was it liie this the first day u installed?. There might be issues on your inverter

It's same setup
I didn't do load selection or anything like that

durodee:
Do you use the same socket for your equipment when on Nepa or inverter or do you have a seperate setup for your inverter? If a seperate setup check your connections and earthing. There is a bridge of wire somewhere.

Sms sunmate 2kva

brightk:
what kind of inverter are u using?
