Most times epistles are necessary S007.

Great job Makavele!

I second the motion above.
A 6-way DB for your AC in/out, booster pump etc. This will fit nicely in that space cluttered with 20A switches.

The a/c in is already drawn from the main house DB a dedicated breaker before it reaches the 20a switch as a secondary disconnect, so thats enough protection.

I actually thought of getting a miniature DB for the a/c out of things, but thats a story for another day.
it would have been easier in the first location, as it is, the inverter was relocated to a more spacious spot, albeit far from the main house DB.
so too much work to start joining and drawing load wires all the way. will be done but not in any of my plans for now.

So at is my battery bank stands at: 19680 kWh and panels at 3kWp.

The only issue I am having now is some of my batteries are out of sync.

Would have to order more balancers before it's too late.

And I think I would have to create a dedicated earthing rod brouhaha for the inverter system; because

I am having issues with that annoying un-grounded current flowing through the inverter chassis when I am standing barefoot on the floor.

How do I fix this please?

And the final look . . .

Replaced the sockets with 20A switches for input and output disconnect; the 3rd one up is for the automatic water pressure booster.

Both bars installed and onto the next one . . .

And it's a wrap folks . . .

So I took Mr Niyi's advice and gave the busbars some good spacing to prevent stories that touch,

This is correct for cold weather and early morning.

What about a 26°C afternoon with full sun and clear skies such as we have seen in the last few days? You can easily overshoot nameplate in that scenario.

Full sun and clear skies?
It's been raining back to back here for days;
and when it's not raining, its cloudy, dark and hazy
and i have been burning diesel like no man's business
3kw producing just 500w at end of day

I dont wanna fix my car. Just coming to try out the recipes

How about that?

Barezzi:
Nice one Makavele.
Any updates?

Yes, by 10pm tonight I shall sir!

Thanks

NiyiOmoIyunade:
Great work boss.

I have said it before and I'll say it again - your DIY skills are above par - many a professional installer would be unable to do such a neat job as you have done - all aesthetics to be sure but a key and desirable aspect of the job regardless.

A few observations/questions if I may;

1) DC Bus bar placement - I hate to see the +ve and -ve so close together - think what could happen in the event of an inadvertent or malicious short!!! e.g you tightening something with a spanner and spanner slips - your entire battery bank would be dumped through the short with disastrous results. My reco is to saw that wooden base in half and relocate one terminal at least 2 feet away.

2) What are those two 13amp sockets on the wooden board meant to power or do?

3) White breaker like device - is that some sort of SPD or just a circuit breaker or combiner box? Please tell us more about it as I couldn't make out the details on it

Thank you sir! Do not fret for the busbars will be encased in 2 different compartments, i can access one terminal to screw and unscrew while the other remains closed. But after careful thought, i think i best follow your method, a very easy way out.

The 13 amp sockets, just wait for it. You will see.

The white box; just a fanciful changeover switch to replace the commonplace knife switch.

i am beginning to fear for lack of space on the main board so as I continue to install, i will make deletions and/or modifications. Should round up today though.

Thanks

Lovely ! I can see them all ready for action .. Observe the wall mounted 5kw psw inverter is very firm on wall ! Goodluck !

Very heavy on hand, but feels like paper when hanged,
It's a beast though!

In retrospect; this was how I started.





Do not despise the days of little beginnings

It was past 12 am by now and i gotta be at the office tomorrow; so i quit here;

will continue in the evening.

Moving ahead

And it's taking shape

Now the calculation and drawings to make sure everything is dead center and accurate.

dont blame me, i am a perfectionist and i love it so

found a board; cut it to shape and mounted it. .

stripped a little bit of the edge by accident but will cover it up later

Inverter mounted; thanks for wifey who helped me drill...

still tryna make a decision; along came the bus bar. . .

can handle 200A of current

With this picture a work of 10min may turn to 1hr.

lol

work in progess,,,stay tuned

I think this position is very personal to your own case and it doesn't conform to any electrical standard. I feel it will be proper you keep it as a personal experience such that you will not mistakenly mislead someone else.

Well said !!!

Oga Makavele,thanks for the patronage once again .. Am grateful !!

Anytime; Anyday . . my nigga !

Congrats on your new CC Sir.

Welcome to the wonderful MS World.

Is that a Drok DC Amp meter I see there (2 pcs)? Please beware, though rated 100a and 75mV, the shunt metal is thin and tends to run hot at higher amperages - you will find the shunts on the Victron and Fangpusun clones much more substantial and ditto for the Trimetric.

If you are in the habit of passing high amps through the shunt, it will get very hot and there will be losses - anything over 60a you may need to upgrade to a more robust DC meter. Also, the meter is not bidirectional so I guess that is why you have 2 units to separately monitor amps in and amps out of battery. Further, it does not auto reset the energy count at full charge or at end of day.

For the meantime, it is a cheap and reliable way to get into monitoring amps in and out of a battery bank

Thanks.
Mine is actually Bayite version sold off amazon with excellent reviews (about 896) and rated Amazon's choice.
And yes, I am aware it doesn't measure reverse current; that's why you saw two. And I do not intend to use it for daily statistics;
I only got it to see whats happening to my batteries; every now and then; when I take a peek. That's all.
I already have the AC version which I use for real-time load draw measurement from the inverter (on the AC side of things).

Lemme sign out in peace abeg

Stick to your ROY SOLAR

p.s.: u need to come take me to 48V sir, edakun !!

sharks776:
Are you sure about that?
What is your proof or source of info please, let learn.

Dead sure, proof is from talking to hundreds of native Americans who do commercial installation
and they all prefered the star followed by the classic.
outback was a third choice whenever the other two were unavail or just for "fanboyism"

zeestone99:
Congrats man, u r welcom aboard.... E b lyk sey morning star don dey win outback n dem midnite classic o, barezzi dapsyra do sumtin

Did a thorough research and morningstar wins; by a slight margin though. Outback = useless

OnePunchMan:
thank you for your Business sir...

Anytime ; Anyday !!

hancock:
Nice one

Time to order for the battery balancer. The usefulness and need to have one connected to a battery bank have been overflooged just in the last two pages alone

Thanks, HA02; our saviour!

The eagle has landed . .

^^ One love !!!

They were trying to save their vehicles cos' they don't have a comprehensive insurance package.

You skip insurance, thinking you are doing the insurance coy, you are doing yourself.

If you have one, run and leave the car to burn to ashes, go home sip coffee, file a claim and

get a replacement within 2 weeks.

This is also what happens, when you use your last card to buy a car and drink garri thereafter.
