This is the only fuse in the unit and they are intact, the unit turns on and trips off immediately

Drgreatone:

You most likely av a fuse cut. If savvy, open the fuse box to confirm if its internal wire is cut. If yes, just get exact same fuse and plug back in

Did you try to test those two fuses for continuity?

noel76:

You need a multimeter to do an actual test of continuity on the fuse and confirm if they are still active.

Good morning house, please i need inverter expert help in here, i have an eco solar 3.5kva 48v inverter, 3 days ago during the rain d light went off and refused to stay on, it always trip off went d inverter is powered on, and d display is showing "fuse trip" how do i go about it? D inverter uses 4 batteries and 8 solar panels

Morning my ogas(s) at the top. Please i need clarification.
1. Is there any simple way one can read daily energy yield/ generation ( KWH) from Felicity charge controllers ? Either from the device itself or with the use of other affordable and simple to use accessories.
2. Are there other good mppt charge controllers within the price range of felicity that can show the data?

@adrusa, @xtremeidea, @zeestone99,@ jonescosmos @DaniellaDokubo @others please.

Your question has been forwarded to Felicity BMS and Wi-Fi department.

Waiting for response.....

KWhr is calculated from KW using the formular KW x T where T is time. The process can be done automatically using simple scripts. I use Home Assistant (HA) which takes KW and converts it to KWHr on an ongoing basis.

So, to answer your question: Felicity CC don't calculate the KWhr but there are many ways to get KWHr on an ongoing basis.

noel76:

Don't stress yourself it's a board issue.

If the fuse where bad, it won't even come up.

Where are you located?

On average over 20kwh on a sunny day and about 15kwh on a cloudy/rainy day.

swagifted:
how many kwh do you generate in a day.?

Thanks for the reply, i am actually looking for something i can use to be able to monitor the performance of my setup as an ordinary user.

Is the " home assistant" a device i can buy and plug into the Felicity charge controller?

In your previous posts, i learnt about the RJ45- serial cable and then installing an app on the system. However, it seems the cable needs some technical adjustments that i was not able to understand.

No but I just discovered that it threw this error code instead F14 DC_OverCurr_Fault.

jonescosmos:
Did your Inverter throw this F20 Tz_Dc_OverCurr_Fault Error Code?

Check from device info page and see.

The repairer later told me they are go to change the board he said the board is 90k while he's own service fee is 40k, I just vex go oreder a new inverter from AliExpress for abt 109k or so picture below is the new inverter I ordered 3600wat but it actual power is 1600watt

osayuwamwen:
I have given repairer both inverter and controller the guy told me that the Felicity controller is repairable and it will cost 25k while the fore solar inverter is 50/50 and he told me 40k for that

Ferdiwar:
On average over 20kwh on a sunny day and about 15kwh on a cloudy/rainy day.

impressive...how much panels do you have on it?

Chaiii see better soup. We no de close, I for run wire tap small. Enjoy

I received my 3 units of Felicity 25KW yesterday, I intend to replace my 4 Units of Felicity 15KW and use them to redeploy my redundant 16KW Deye Inverter.

I noticed some differences between these units I got and the 25KW sold in Alaba and I contacted Felicity Engineers in China straight off.

They have revealed some important points about both models. They also sent the UN38.3 of one of the Pack, waiting for the second one.

I will not post our conversation here in order not to cast their updates in Alaba and drive them to start changing stickers and writeups to circumvent the system and sell to you.

TO ALL FELICITY LITHIUM BATTERY 25KW, 15KW, and 12KW PROS{ECTIVE BUYERS in 2024 AND FUTURE, FEEL FREE TO REACH OUT FOR THIS IMPORTANT GIST BEFORE YOU BUY.

Please What's the current price of these batteries in Nigeria?

Also please share the secrets on the batteries in Alaba. You can give a hint

How does overload affect the inverter? I thought it will just trip off when overloaded?

osayuwamwen:

All good.
Well I have never turned off my inveter even when it rains with lightning. It is too boring and dark without power during rain.

Sapiosexuality:

Some inverters will act otherwise.

Ferdiwar:

It's the same error. The number may be different in different model. And the cause is what I told you before. 1) Your panel is exceeding 17A Isc during favourable condition and your controller is thus unable to clip the Imp to 13A.
Or
2) Total wattage at that point is in excess of 6500W and the unit is unable to handle the excess.
Or
3) Your discharge/charge current limit is too low relative to load and panel size.

What will I do my inverter spoiled during the rain every time thunder strike my own trip off
And will not come on again

5x 570w Longi panels and 5x 625w Jinko panels.

swagifted:
impressive...how much panels do you have on it?

Kindly explain more of the No 3 please.

As for No 2, the total installed panels are not up to 6,000w.

The installer will be coming over the weekend to carryout a check to determine if there's a short circuit to frame or anything like that.

Please guys,my friend bought 2*220ah tubular batteries from someone but he's complaining that the batteries are weak already.

So will changing the electrolytes of the batteries resuscitate them? Or would it be a fruitless exercise?

And if it's adviceable,can I also get where to do it in Lagos, thanks.

Good evening have dropped many DM on your mail no response. I need the 12v inverter

adewasco2k:
I have some items for sale as i am upgrading

1. 12v 280ah lifepo4 battery with bluetooth BMS i got from Valto just April (battery circle: 10)
2. 12v 150ah lifepo4 battery with bluetooth BMS i got from one other guy here March (battery circle: 29)
3. 12v 2.2kva ZGPT hybrid inverter i got from Valto

if interested hit me up.


I am upscaling to 24v and wouldnt be needing all this

easyyoke:
Please any inverter engineer that could repair a faulty inverter in Ibadan here please?? If you repair inverter in Ibadan, please reach out🙏🙏🙏🙏 and if anybody knows any confirmed engineer in Ibadan here please. Needed for an urgent repair please

Have you gotten the help you need?

When you say " buy it from someone" i want to assume its second hand

When did he buy it?

Does your friend have maintenance culture?

Are you sure the person did not know of the issue before selling?

Changing the electrolytes to resuscitate it , is 50-50 thing and since its cheaper to charge than buying new battery, i would suggest he try it first.

Just locate one good battery charger and give him go ahead

Take it to repairer if u are lucky they can repair it or they change the board which is like getting a new inverter, it is the same thunder that destroyed my inverter even my controller but was able to fix my controller but the inverter required change of board

Same way my 3.5kva inverter got destroyed by lightning and repairer was quoting almost 200,000 for new board and workmanship, i just kept it aside

I finally bought a 5kva 24v felicity

bigrovar:


Like everyone have added, you need to review your electrical fault system including your earthing. You said you had your earthing done, have you had the earthing independently tested to ensure that it is within the recommended resistance required of a TT earth system (which is pretty much what we practice in Nigeria)

You should also ensure that the earth point for all your electrical socket are well terminated, and those terminations are still functional. You can use a multimeter to carry out basic testhing. In my case I run the connect the red probe to the live, and neutral, note down the voltage (which should be around 230v) then I do this same this time with red to live and black probe to earth / ground (the top part of your electrical socket) it should also read 230v. This will let you know the socket it connected to a sort of ground. (It would not tell you how active your earthing is but it is a good indicator)

Light bulb test can also help, get an incandescent light bulb and connect it to live and earth. A well lit bulb indicate decent earthing. Run this across most of your socket to ensure they are well terminated to earth.

Non of the above test should replace a proper earth resistance test which can only be done with proper tooling and by a competent technician. Often time, NEPA officials tend to have this tool so you might want to reach out to your local NEPA office .. you might be able to have someone come run a test on your setup (off the record).

I attached a picture of my previous earthing setup.

For a TT system 200 ohms and below is recommended but anything below 100 ohms is ideal. The earth resistent tester should carry out test of the earth electrode and also check resistant from central earth bar (from your db)

Lastly on the Main Earth Neutral Bonding (MEN). This is not recommended for a TT system. A TT system is technically suppose to have MEN happen between your earth electrode (earth rod) and transformer neutral. The connection between your earth rod and the transformer neutral is meant to happen through the mass of the earth.. basically the soil / ground between your ground rod and your transformer ground (which is bonded to the neutral that comes into your house. (See the attached diagram)

You are suppose to have only 1 MEN in a circuit to ensure that ground loop fault have just 1 path of return. Bonding Earth to neutral in your DB creates multiple fault path because it technically means you have multiple Main earth to neutral.

Lastly, you might want to try installing an RCD to or an ELCB. The latter to detect earth leakage, the former to detect a fault in the system and trip (in other to save life)

Be careful though RCD can become a nuisance if your electrical connection is not properly made.

Oga at the top! Good to see your comments.
I travelled and just got back to do the checks. In the meanwhile the freezer was switched off , allowing the goods inside to thaw.
My findings:
1) Socket test with voltmeter: My supply voltage from inverter was 210v. L-N test-210v, L-E test -210v and N-E test- 00v
2) Proper freezer examination: I saw a cut wire (light brown colour) that likely supplied the thermostat side. There was a STRONG possibility that it was touching the chassis of the freezer BEFORE I pulled on the wires as I was checking
Result:
1)When I switched on the freezer, there were no more shocks. Freezer chassis to earth reading was 0.18v on the voltmeter BUT the tester bulb showed a dim glow.
2) Power consumption from the freezer went back to normal
3) No glow or shocked from the shower or other taps/electrical appliances in that section of the house.

My conclusion for now:
Naked wire to chassis. Will be on the lookout for further issues. Due to my schedule, it may be up to a month before I freezer tech can have a look for me.

Thanks for the pointers given

olopan:
The purpose of earth on appliances is to take dangerous voltage as the case of a metal container of an appliance touching the live conductor.

For you purpose, I believe
1. Your fridge has a rust which in turn has bridged a live conductor somewhere, hence the light voltage shocks received
2. Your earth might need improvement, as i believe it has probably had a resistive buildup, hence the shock you may be receiving.
3. check your water supply for the shower and see where you have electricity been in the mix of your setup. (suspect is likely water heater) try and ensure this is grounded and free from rust - live container bridge.

It seems your number one comment was the issue. It was a naked wire that was likely touching the chassis. Since then, everything has returned to normal with no more shocks anywhere
