The weather has been rainy and cloudy most times today in my location. My inverter reading is as shown in the image.
What should be the performance rating of my system consisting of a 3 pieces 685w panels connected in series to a 4.2kva inverter?

the performance rating should be 2

Yes pls,which battery would you recommend.
155ltr deep freezer
40 inch tv
Few bulbs and 2 rechargeable fan.
Thank you

AyobamiOluwole:
If you are concerned about Fake batteries, I would assume you have made your choice already (inverter setup in this case). The next thing is to ask the right question about the battery to buy.

I will recommend you buy from trusted sellers here who will give you warranty and also build system using correct batteries like:
Dam5reey
MrReed
Valto

But if you fear them, or they are far away from you, then find any certified Felicity Solar shop to buy a battery with warranty card. Mind you, Felicity batteries are ok but I’d rate them tier 2.

As for the battery size, a ~4Kwh and above battery will be ok especially if your freezer is not a Solar freezer and will also run 24/7.

Ezimuoh:
Which kain advice be this one?

I dont get..I said wat i said, install ur panels in parallel

Gshems:
You people and advice. Person dey fear 5v but you dey advise am to connect 2 13a panels in parallel for an inverter that takes a max of 18A

I have bren doing 36a on a 20a input for 2yrs now

eghos12:
If he parallel the amps go pass 18 and it fits reach 25amps. That's too much to clip o. Any risk make he fit Do na series

wat makes u tink he sees 18a..

Do small research on battery capacity tests for that brand you just recommended fes 😁

Okay. That's a start. Have you tried to take the display unit apart and disconnect the communication board to see if the LCD lights up?

mosak:
Thank you for the response. I Have been to Arena market, most of the repair guys said they don't repair the LCD or they don't know how to repair it . The inverter model is VMIII TWIN 4K. The power button is working, it just the screen and other buttons attached to the screen that's not working. It got blank when I tried to use communication cable on it

Hv not been in this space for a while that why sah..got 2 brand new 535w.. Sold one yesterday.. 1 left.. Although me no they lag sah.. Na IBADAN I base.. If you base here come buy am and add to your set up.. No need to buy cc or wahala yourself on selling and buying another inverter.. Just buy the 535w...and when you are ready to upgrade, it will still be very useful for you as well..

hoover420:
Thanks jare, appreciate the encouragement. Waited for months to get the 535 watt but since it’s not forthcoming, i decided to go for the 585 before I exhaust the money I already saved for it. I’ll just be patient and go for the best option, cos tbh, I’m currently enjoying the set up as long as I see just 3-4hrs of grid daily. My battery is just 3.6kwh so it gets full on time

Troubleshooting the Shocking Truth

In the course of troubleshooting this issue, I ended up installing a brand new earth rod and earthing connections. I had wrongly assumed that there was something wrong with the earthing of the house (yes, something was wrong, but not necessarily what I thought was wrong).

However, I noticed that the fridge, the freezer, the microwave, and the cooker still shocked to the touch.

But I discovered that there was zero shock if the power came from the inverter and not from the mains.

When I shared this with my very able electrician, he said, "Let me come and confirm." Once he confirmed this issue by testing the Live, the Neutral, and the Earth at the outlet that powers the fridge, the freezer, the microwave, and the cooker, the remediation process started.

Identifying the Culprit

We then went to the distribution board (DB) and tested the common earth, the common neutral, and the common live, and each of these would light up.

So the next thing he suggested was to go to each outlet in the house and check the connection, which would have been very tedious. I said, "OK."

Next, he said, "There is a better way."

He said he would try to sort it out at the DB level.

So we started separating each of the earth connections at the DB and tested. The earth would light up until the problem circuit was identified: the earth wiring to an AC switch and a looped wall socket in the guest room.

He then went into the ceiling and asked me to confirm from the ground which room he was in (the problem room). I told him it was the guest room. After he traced the wires to the part of the wall where the wires were, he came down and went straight to that socket, and when he tore it apart, we confirmed our suspicions.

The problem was that in that one circuit due to the use of a single color of wire, whoever wired the house did not know when they bridged the live with the earth. So one had the same result testing live and neutral and earth with a tester.


Once this was fixed, I went back and turned on the circuit breaker that I installed between the AC input and the inverter, and voilà, no inexplicable ramp-up in consumption occurred. I did not bother to switch off the breaker embedded in the meter, and everything is as good as it was.

The Cost of Cutting Corners

This is a practical example of how much cost one ends up incurring in time, material, labor, and worry just because standards (like a different color of wire for each type of connection) are ignored and sidestepped for expediency.

He told me he did this because of me, and that many electricians will often ask you, "Are you wiring a new house, socket, or light?" If you say yes, they will come. But if you tell them you have this kind of issue that I have—a maintenance issue—they will give any and every excuse in the book not to be involved in this sort of troubleshooting.

All in all, I am glad. I can finally trust that the house will not make me guilty of involuntary manslaughter.

The Office Debacle

This leads to the story of what happened in my office and how I ended up spending a lot of time to untangle the mess/hack job that was done when my electrical assistant got frustrated. (He wanted to run new wires; I said, "But I already bought wires before, even made sure it was up to code. Why should I abandon the wires in the ceiling and redo the wiring? It would be such a defeat!"

I ended up going into the ceiling of the office myself to sort out the mess of a connection that was done there by a new set of inverter people who do not understand why standards are made and why they need to be followed. I will address this story in another post.

For Everyone on Solar/Inverter: The Electrician Who Found the Fault Nobody Else Would

Most of us on this thread have spent good money on inverters, batteries and panels. But here is the hard truth: a solar or inverter setup is only as safe and as efficient as the wiring and earthing behind it. A perfect inverter on a bad installation will still frustrate you, waste your load, and in the worst case, shock somebody.

I am posting this because I found a man in Abuja who actually understands that, and I am staking my reputation on him.

First, who he is

His name is Daniel. He is Trade Test 1, 2 and 3 certified, and NABTEB certified. He is a qualified tradesman, not a "boy who learned small wiring."

What he can do:


Electrical drawings and design
Full house and office wiring (done to code, not to convenience)
Fault tracing and troubleshooting (this is where most installers run away)
Thunder arrestor / lightning arrestor installation
Earthing installation and remediation


If it is electricity related, and that includes the mains side of your solar setup, he is your man.

Why the solar crowd should care

Here is exactly the kind of problem he solved for me, and I suspect some of you are quietly living with something similar.

Whenever mains power tripped, my inverter would keep ramping up and running at about 50 percent load for no reason I could explain. On top of that, whoever originally wired the house had used a single colour of wire for everything, live, neutral and earth, which is a violation of basic standards and a nightmare to diagnose.

I did the obvious first step and installed a brand new earth rod and earthing connections, assuming the old earth was the culprit. It was not, at least not the way I thought.

Then I noticed something frightening: the fridge, freezer, microwave and cooker were all shocking to the touch. But only when power came from the mains. On inverter power, zero shock. That clue turned out to be everything.

When I told him, he did not give excuses. He said, "Let me come and confirm." He tested the live, neutral and earth at the affected outlet, then went to the distribution board and tested the common earth, common neutral and common live. Every single one lit up on the tester, which should never happen.

His first instinct was to check every outlet in the house, tedious as that would be. Then he stopped and said, "There is a better way." He decided to isolate the fault at the DB level instead. We separated each earth connection one by one and tested, until the earth stopped lighting up. That pinned the fault to one circuit: an AC switch and a looped wall socket in the guest room.

Here is the part that impressed me. He climbed into the ceiling and asked me to call out from the ground which room he was standing over. I said the guest room. He traced the wires to the exact wall, came down, went straight to that socket, opened it, and there it was. Because the house was wired in one colour, whoever did the original job had bridged the live to the earth without knowing it. That is why testing live, neutral and earth all gave the same reading, and that is why my appliances were live to the touch.

Once he fixed it, I switched the breaker between the AC input and the inverter back on, and the mysterious ramp-up in consumption was gone. Problem solved, completely. My inverter finally behaves the way it should.

Why this matters for your setup

That single bridged wire could have killed someone, and it was quietly stressing my inverter every day. If your system is behaving strangely, tripping, ramping up, appliances tingling to the touch, the problem is very often not the inverter itself. It is the wiring and earthing feeding it.

Daniel is the kind of person who will actually trace it instead of telling you to buy a bigger inverter.

He told me plainly that most electricians will happily show up for a new wiring job, but the moment you say "I have a maintenance and troubleshooting issue," they vanish and give every excuse in the book. He does not.

My appeal to you

Someone this good does not deserve to be sitting without work. Please give him jobs and support him. He is Abuja based.

This is not a sponsored post. I am simply an over-satisfied client who owes him one.

And if he ever gives you any issue at all, come back to this thread and raise it with me directly, and I will intervene.

A friend was complaining the other day that everything in his house was giving him an electric shock. A tester showed live voltage on both the live and neutral lines. After four hours of troubleshooting, the fault was traced back to a faulty freezer. Sometimes, the issue isn't faulty wiring at all; it could just be one of the appliances connected to the system.

Troubleshooting requires patience and a lot of expertise, which many young Nigerian technicians hate to deal with. They often think it isn't profitable, especially since some clients refuse to pay for the time spent diagnosing an issue if it doesn't involve a fresh job from scratch.

A similar scenario played out when the elderly electrician that handled my solar installation invited a young guy who is supposedly a solar installer too, to lend a helping hand. At a point during the inverter connection, I overheard the young guy telling the man to do a connection "anyhow" that it would still work but the elderly man cautioned him that he doesn't do his jobs anyhow so as to avoid future issues with his clients.

That single bridged wire could have killed someone, and it was quietly stressing my inverter every day. If your system is behaving strangely, tripping, ramping up, appliances tingling to the touch, the problem is very often not the inverter itself. It is the wiring and earthing feeding it.

Daniel is the kind of person who will actually trace it instead of telling you to buy a bigger inverter.

He told me plainly that most electricians will happily show up for a new wiring job, but the moment you say "I have a maintenance and troubleshooting issue," they vanish and give every excuse in the book. He does not.

My appeal to you

Someone this good does not deserve to be sitting without work. Please give him jobs and support him. He is Abuja based.

This is not a sponsored post. I am simply an over-satisfied client who owes him one.

And if he ever gives you any issue at all, come back to this thread and raise it with me directly, and I will intervene.

I tell folks, "a good product does not need over-advertisement".... only bad Government does.
Your good work is what will sell you, just ensure you don't get arrogant, when you finally blow.
Thank you for bringing this us, as a satisfied customer.

@Mr. Daniel, keep it up, remain humble and you will blow.

Is there a way to set the charging parameters so that the system stops drawing power from the grid once the battery is fully charged?
