If you want to DIY you will need the following:

1) Earth rod and earth clamp bolt
2) Earth mat, there are already made in the market, or you can buy 20mm or 25mm flat copper tape and DIY the thing.
3) 16mm² single core cable to run to the earth connection in db or changeover
4) Industrial salt
5) Charcoal
6) Cow/ or poultry droppings


1) Dig a hole (at least 4 feet)

2) Put your copper rod in and drive it down till it's flush with the ground

3) Use clamp to secure the 16mm² wire to the rod and make a good electrical connection to the earth mat. This wire will run to the final earth location which is your inverter in this instance.

4) Add industrial salt and charcoal.

5) Pour in water to mix.

6) Add the dung and pour in more water.

7) Finally, cover the hole

The whole purpose of providing earthing is to discharge the leakage/fault current safely to the ground. All these are just to increase the conductivity of the soil or reduce its resistance. Adding of charcoal, cow dung, industrial salt and water (termed as conditioning of pit) decreases soil resistivity. Industrial standards requires that the soil resiativity be less than 5 ohm.


A dedicated earth is just an earth for a particular device, the whole house may have an earth which may have failed or compromised, a new dedicated earth is just for the equipment you want to secure.


The experts may have other great ways of doing this.

I have 4units of [b]Felicity IVEM5048 (5KVA 48V) Inverter with almost zero Idle Power Consumption (0-25W)
3 are less than a week old, 1 is less than 2 months old. Everything functioning, no faults, no repairs of any kind, firmwares updated to Latest V14.02, warantee seals are intanct..
Reason for selling is that I finally recived my 16KW DEYE I ordered.
You can reach me on 08033252184 for a video call so that you can see them functioning, I will be decommisioning them in a few days[/b]

House abeg o!!!

I have been hearing this often and often, from your experiences here, do the tubular batteries in our markets here really last 5-8years for real?

Likes of Inverlast, Eastman and others
Help enlighten me please

Namzy:


I've been using mine for 4 years. Just don't discharge below 50% and I'm sure you can get 8 years easy

Xanderone:


Is this still available?

viperVIP:
Thanks for sharing your experience
How many batteries are you using connected together?
What's your max charging current?
How often do your water needs topping?

Good evening house

I have a Luminous 1.5kva inverter with 2x fairly new batteries. 12v 220ah (matrix tubular)
Batteries still have about 13months warranty on them.

Happy with N350k for the lot.
(Please, I can't deliver. You'll have to come pickup in Lagos, Ikeja axis. First come, first collect)

Don't do crossover in darkness ooo... Get this deal today. I can even include a small extra Christmas present sef.
DM me or reply on here if you're ready to pick up now. Once it's gone, it's gone

350k? , happy sales bro

Thanks for the info, I will definitely use it with battery. What if the surge demand is less than panel yield, will it still trip off the inverter?

Appart from your Batteries being full or floating, You can't compare the efficiency of Independent CCs to Hybrid Inverters.
I had this same problem when my setup was 8x360w (4s2p Wiring) with 60A CC and 3KW Inverter on 4x220Ah FLD Batteries. The Banks never get full all day long and no matter what I switched on, I never got past 1.XXKW production from the PVs according to the display of the CC just like what you have posted here.

When I switched to 5KVA Hybrid with 100A MPPT Built-In Charging at 60A, same 4x220Ah FLDs, rearanged same PVs to 8s, The Inverter sucked almost 2.8KW from the same panels begining from around 10am till 3pm, Batteries gets fully charged before sun down while powering more loads alongside than the prior setup.

Conclusively, I nothiced that due to a broader intelligent programming of priorities on Hybrid Inverters, they tends to query for more power from the PVs than the Batteries. (Output Source Priority Setting: SUB) once you do this, S=Solar, U=Utility, B=Battery. So the SUB order means get every power you need from the Sun first, If Solar Energy is not sufficient or not available, Make it Up from Utility, If both Solar and Utility are not available, take power from the battery banks.

This is one hell of a function that Seperate CCs doesn't have. Because the Inverter sees only Battery Input as power source, it sucks from it, remember that the Battery Banks are closer to the Inverter than the PV and CC in terms of ampearage, the batteries are then always draining.

This whole Hybrid Inverter Intelligence in my own words is revolutionalised in my Deye Inverter which dumps all dependence on Grid/Battery and shifts to Solar inputs for Power, in turns, it sucks everything is can get from the solar before considering Grid or Battery.

In my humble opinion, dump the setup of CC, inverter, Battery and shift to a good Hybrid Inverter, i guarantee you won't regret it. Just make sure that yout setup is properly protected from the storms both from Grid and Solar.

1) Epever Mppt CC 150v/60a.
2) Srne Mppt CC 150v/60a,
3) Powmr Mppt CC 190v/60a.
Please, choose the best two for me from above that can either charge lead acid battery or lifepo4 battery.
Thanks

Aw can I get it boss

bigrovar:


Jinko only has one distributor in Nigeria ( based on their website) they do have presence in Alaba. They also happen to be the official distributor for JA, and Longi.

You can reach the +234 803 373 1860 (as displayed on Jinko website)

isangjohnson:
With all the rules duely observed, if lead acid battery can last for 5 to 6 years with lifecycle of about 500 to 800, then lifepo4 may get to 15 years under the same condition with lifecycle of about 2000 to 2500.
I'm waiting to see how many years my tubular will stay alive too. The highest power drawn from my battery is 30%. It's about a year now and I've never top water before.

mahkanjuh:


Thanks, does that mean all these binatone plug in AVR is not advisable Kindly suggest then

Namzy:

I have 2 12v connected in series, 30a charging current although sometimes can get to 35amps water topping about 3 or twice yearly because I don't usually allow the water water level indicator get to the red lower line

nnadychuks:
hw much does it cost to top the acid, and is it something you can do on your own?
