Hi my People,

I missed this forum.....been quite busy...work nor let me see road

Kudos Guys

Monlo:


Yea,more work,more money!
Enjoy

Good to have a nice teacher back to classroom.

dicksonadams:


Boss can I get someone to help me do this also? The engineer that install mine had charge me twice.... E. G change wire, new cc but to no avail

Some installers can really be frustrating & that is why I turned diy.

A 450w should really yield more than 100w except u've paralleled ur installation if they're 150w panels or lower. Also, if u mix panels of different watt, CC tends to pick parameters of the lowest panel and limit production activities to protect the lowest panel thereby harvesting in that region irrespective of cloudy sky.

I stand on all what previous gurus have mentioned because I had similar experience too.

I the course of my diy experiments, I had four 150w panels installed in series of four instead of 2x2 or just 3 series. And on the 3rd day, it was really sunny, guess what? I heard a loud BANG! from rooftop. I never bothered to check until my harvest dropped to a shocking level. I had to audit the whole setup and discovered the last unfused panel in the series got cracked! Of course after disabling the culprit, my harvest returned.
It is very true what johnkester said. The sun has moved to another limit due to earth revolution. And during an upgrade I reset my inclination approximately and got higher yields dispite the rains.
By the way, I hold constant that ur cables/connectors, breakers etc are proper. If so, then tell ur location and let gurus close by do audit for you.

Cheers

JUO:
I own 2pcs one 500w that operates at 400w and one 100w that operates at 35w. Works very well for me

Ur lucky to have dem. it is no load to ur setup.

@ babaegun
I don't know if it is available again. it's a long time

babaegun:


@SolnergyPower

I've not see any within that 100W range. Maybe some guys in-house will still share better ones with us soon.

I have 300w AC Areo dry Iron I have been using since 2009 when I have not dreamt of inverter or solar. it so efficient that it melted the lower plastic casing and it's thermostat knob making me to hate using it for sometime. Last year, with the fear of recession and the need to protect my battery bank, I had to dig it out from my dusty store & insulate the casing from it's element or iron base.

now I enjoy pressing cloths anytime of d day with just 300w on my 2kva/1600w inverter.

I have since dumped my Siemens 2200w water iron.

for those looking for inverter friendly pressing iron, check it out maybe you will find an improved version of it.

Barezzi:

Thanks Kiekie, it's always a pleasure doing business with you.

that is why I love buying batteries from him. you get good quality and peace of mind.

Kindly post the 200Watts and 160Watts specifications.. for better assistance..

A quick rundown of how to connect mismatched panels

1. Different wattage, same Vmp, different Imp.... Best connection is parallel...

2. Same wattage, different Vmp, different Imp..... Best connection is series...

3. Different wattage, different Vmp, same Imp .... Best connection is series...

4. Different wattage, different Vmp, Different Imp... No suitable connection....

am impressed, a whole lot of people in Nigeria RE will die that knowledge/info

whereby you can easily PICK such info off Nigerian sites.

Nigeria WINS
up RE/AE in Nigeria. am proud to be part of RE enthusiasts.
keep up the good work Dr. Solar!
and don't forget some youtube clips of the assignment

mcTrinity:


if you have 500w load on a 24v inverter system, it will draw 2.2A from the AC side
P=I/V
I=P/V = 500/230 = 2.17A

but from the DC side, it will draw 21A
500/24 = 20.8A

Energy can neither be created nor destroyed but can be changed from one form to another. power on AC side is equal to power on DC side (assuming perfect system without loses). The only parameters that varies are current and voltage

am guided by ur principle above.
very straight forward.
it is appreciated.

@ Refa

Thank you so much for a detailed
insight to inverters and their working conditions,

well I will keep studying the inverter and keep the house informed for the benefit of some with similar
inverters

Thanks again

Obascoetubi:
which inverter?

bigbrovar:

Name of your inverter. From what you have posted it seem your inverter uses between 100w / 110w for idle load which is very high but not unexpected with some inverters

Saipro:


I think the difference could be accounted for by the energy consumption of the inverter itself. It is an electrical appliance and will consume energy to drive its energy conversion circuitry, mostly via losses.

Thanks All

It has been bad trying to post here in the last few days
particularly if you don't copy remarks before posting them.


the inverter is Microtek 1,600w (2KVa).

In addition to your views above. do you think DC Amps drawn by the inverter is same as
AC Amps irrespective of the waste due to conversion?
I know DC watts is not = to AC watts

Hello House
My inverter waste much of my precious battery power.

It’s my belief that DC watt is 92% of AC watt and current stays same whether DC or AC.
Can someone help with explanation why my inverter draws so much juice just to produce so little. For instance, it draws 11.60A@307W DC to produce 1.47A@247W AC to power load (of a Deep Freezer, 32” LCD + 2 Decoders, Newclime Ceiling Fan).
See readings at 8.59AM this morning.
For the time being, I installed DC watt meter at output of my Battery Bank and another just before my CC to read-off harvest directly. While AC watt meter to monitor my AC loads.

An experienced explanation will do my nerves good.
Thanks
(Meanwhile, my inverter idle state is just 27.7w and has good surge allowance when fridge and freezer compressor kicks.)

I fully agree with you,
battery is necessary in a solar setup in Nigeria

unlike developed nations

nice work Dr.

GeorgeD1:


my brother, it's just so disheartening. from solar products to tyres and even commodities the story is the same: artificially high prices totally at variance with realities on the ground.
unless they start re-adjusting these absurd prices downwards they stand to lose customers big time.

I do not want comment but after thought I believe there is the need to appeal to marketers on the forum to scale down their pinned-product-prices. their is real competition out there.

taking good/standard panels for instance, eg. flames 150w poly/mono PV can be bought at N27k/N30k.
but here the cheapest is N35k

of course marketers will use their usual bla bla bla or alaba dis alaba that to justify their superficial profits on solar products.

however, some of us believe forum patronage will encourage marketers in our small community of solar to grow across length & breath of Nigeria.

so the forum should be seen as a place to give rebate (if that word is appropriate here) to members and not just the usual market place.

GeorgeD1:
the current limit challenge...
solar array output clearly exceeds the tristar mppt 60 capacity...

being a non-Fan heat-cooling CC, now I believe tristar is a good product.
just imagine! 60.5A when some CC will advice you to limit your current 55A.

I wish I had one!

thanks for taking up my request to solar depot submitted on this platform for current price list

if you scroll back 2yrs + on this platform you see marketers/dealers rich content & pricelist options. but over the years that seems to be done off screen now. this leave some of us placing orders on konga instead of the forum.

thank you so much.

also I also love oga kiekie1 time lag on lists
thank you too.

let's make Nigeria great

nene2016:
Please below is a table of my solar energy need calculations and I would be grateful if the bosses in the house could check it if my calculations are accurate and I welcome your suggestions.

Thank you for your time.

wastage of ur loads are not what dey seems to be. add 0.25% factor. eg. ur 6w led bulbs are not truly 6w etc etc.

to be on a safe side I agree with what Barezzi said above

Feshizzy:


Thank you once again kind sir,
But I'm more concerned with the position of the panel,
If they are well optimised,
I know the banks and building are weak,
The total harvest was 24ah,
While it was generating 1.4ah
That is less than 30% of the panel rating at peak performance,
I was expecting a generation of about 4 - 5ah during peak period!

pls check the MC4 / cables joint. it may have been poorly connected thus you are losing energy.

Feshizzy:


Thank you very much sir For your response,
What I actually need was the correct positioning for the panels,
As it is already positioned facing east as in relation with the roof,

The inverter,
Is a mercury 2.4kva inverter with two very weak 12v 100ah batteries,

And the wiring was done by one very wack techkie using about 10mm cable for about 10 yards

The solar is on the opposite on the roof of a 3 storey building while the cc is on the 2 storey of the building very close to the inverter/battery,

For the controller, it's a cheapo pwm CC of 12/24v 40ah capacity,

Thanks in advance though.

A re-visit of picture of ur panel and from a DIY point of review of ur installation, I believe it is sufficient enough to give u the needed energy production. what I find odd is u don't have to peel off the black back of the cable. ur cable size is very ok but why peel of the insulating back?

anyway, 40A Cc is thoughtful, the culprit is ur power bank. the PWM CC goes down to the level of ur ba3 & gradually rise or regulate the voltage/amps to ur ba3. unfortunately ur ba3 are not good thus you keep recording low figures which will grow worst till u replace dem.

with ur present state, I advice daytime workloads & nighttime for led bulbs / phone charging only.

my regards!

DMerciful:
If there is no grid...there are better designs to use than grid tie inverter(its like using helicopter to go to church ). Grid tie inverters are expensive and using it for basic purposes that can 100% be fulfilled by normal inverter is not cost effective. Gird tie inverter is not applicable in Nigeria.....using it is just for sensation in my own opinion

with plenty YouTube videos I have watched both of u have valid points. in Nigeria buying sophisicated grid tied inverters in order to roll back NEPA rates on your meter is useless. So the so called grid tie inverters is just to change over to NEPA where conditions are sufficient.

with technology we now have cross over factor whether transformerless or not they're becoming intelligent & more reliable.

Feshizzy:
Good day everyone,

Abeg make una help me out!

We got one 250w 24v mono solar panel
With a pwm solar CC,

Because of how the roof is,
It is facing the east,

And at 2:00Pm it was producing 1.4ah when we checked the CC,

Please note the battery on the inverter was very very low,

Please any possible way to optimise more abit?

welcome to the forum.
on ur question, it is a pity the information u provided is still scanty. u need to do more.

eg. cable size, make of PWM, ba3 type/bank @ 12/24/48 etc, inverter type. it is a DIY setup etc etc.

how did you size ur bank & refill it up at sunrise before complaining the ba3/inverter indicating low voltage quickly.

mind you with little patience u get help soon ( b/cos u have 3 groups in the house- the DIYs like me, professionals, &marketers)

the DIYs are always ready to help base on their knowledge/limit of experience.

the professionals are simply tired of helping or are keeping certain basic info as trade secrets.

finally, marketers are there for all with after sales advises.

if you're convinced you're not getting enough from the house, pls check YouTube there u have thousands of video on various topics on solar. enter ur comments/questions, ur sure to get help.

cheers!
