Why do you say that because it is not monocrystalline Panels?

Not necessarily. True, polycrystalline PV panels might generate slightly lesser power but that's more over a statistical thing when doing long-term comparisons. On the short-term, one can always add extra panels to supply the (perceived) deficit. Don't forget that we live almost directly on the equator and as such enjoy insolation that most others could only dream of - all year round!

My concern is on the basis of your equipment. Undoubtedly, you'll be powering some heavy duty stuff. Power drain might not follow your calculations for surge drains. Cycling loads might however cause an overestimation of power needs too. Your equipment looks like something desired to power either heavy motors or big compressors (standing A/Cs?). I'm sure you've donw your homework well. Don't mind me, I'm merely being my ever-sceptical self

PS: of course you might also be wanting to provide the equivalent of a few days backup power to light equipment especially in areas of poor grid supply in which case your setup might be even more than adequate.

You need to tell us what equipment that you have in your home

The load we put on inverter is about 500 watts

Hello yall.

Does anybody know of a wind turbine seller and installer in Lagos. Thanks.

bigass:



The bolded part is confusing. You said wire from CC ends in inverter then you said on battery where the wires from CC ends.

From your explanation the wire from CC ends in the inverter. Where on the inverter.
The only input source I see on my inverter is for direct electricity from PHCN or GEN. Then the wires to the battery. I thought that the charge controller send the power to the battery. From your explanation, it means you can not use both sun and phcn to charge

biggass, what a name!

bigass:
Sorry ooo Please we want to add solar panels to our inverter. But I am more confused about how these things work. We use 1.5 Luminous inverters with 2 200AH batteries.
How many solar panels would I need.
How do i know if my inverter can work with solar panels.
Aside panels what else would I need.
How do you prevent over charging with solar.
Can solar and PHCN work together in charging battery bank.
How do you run the wires from the solar panel to the battery alongside with ones from phcn?

for starters you need minimum of 1000watts panels, and for this a 45amp mppt charge controller wud serve,..though this setup isnt ideal and doesnt give you room for expansion in the future.....if money is a problem buy 4 units of 250w panels and then 60amp mppt CC, in the future...u can then add 500w panel more, bringing ur total panel wattage to 1500w...wch ur 60amp mppt CC can still handle..and then increase ur batt bank to 4 x 200ah batts. {note: its not good to add new batts to an old bank after 6 months]...


500w continous load is on the high side......pls list the loads.....u cn split them up into daytime and night time loads.
designing a system to power 500w 24/7 will gulp more than 1.5m naira, dont think u r ready for that, so i suggest u manage ur load, if u hv fridge, then the fridge mustnt run 24/7, u can buy a timer switch as earthrealm has explained in his previous post, wch will let the fridge run 6 to 10hrs or more as u deem fit, automatically

if u still insist on 500w loads then buy a 3.5 or 5kva inverter, buy 8 units of 200amp battery, buying minimum of 2500w panels, n dearie u will enjoy uninteruppted power supply, and u bank acct will be abt 1.3 to 1.7m poorer

sorry for the confusion, i meant battery bank.
ok, once again

SOLAR PANELS -- CHARGE CONTROLLER -- BATTERY BANK

for the inverter, once its plugged in...and there is phcn or gen...it will be outputing 24v n above at the positive and negative terminals that is already hooked up to ur battery bank....so that same place/point u hooked up the inverter cables...thats the same point u hook up the cable coming from the charge controller

u said ur inverter is luminous 1500va wch i know its a 24v system

I ve 100A battery and 1000w inverter, how long will the battery last with 600w load.

I will also like to know how to arrive at the answer.

I want to use it in my farm

Urgent info is needed on where to buy SEVEN DAY TIMER SWITCH locally in naija.
I am aware its on ebay and the likes.
Its been a while since my 3 units of timer switches stopped working.
I remember reading online few months ago that the switches do die sudden deaths.
However, i believe the advantage supercds the life span.
When mine were still functional, i enjoyed the way my fridge comes up exactly 7am and off exactly 4pm.
Whenever i am traveling out of town, i connect all security lights to a socket....such that they come up 6.30pm and go off by 7am the following day.

richmon74:


I have even come across a fallen solar panels pole with 4 130w solar panels on a road side which has been there for like 2 months now and no thief is thinking that direction. The stuff is in a very comfortable place that someone could just walk in and dismantle the panels by just loosening few bolts in the night but i wonder why the haven't.

Be very sure that the'll possibly go for battery faster.

location pls....I'm interested in it.

Where are the professionals. Can they assist me professionally? My installer informed me that I have to always connect the batteries to the solar, if I want the solar to provide me with power. I was informing him that there is no need to connect the batteries, because the batteries serve as a Bank and when the sun is not available, you can use the batteries to provide power. I don't know if I am wrong, but at the moment I am so sad.

I DONT UNDERSTAND YOUR QUESTION?
yes..just as the batt bank is connected to the inverter as the time, thats the way the battbank shud be connected to the solar panels tru the charge controller??

so how how u been using it...if u didnt hook up the batt bank to the charge controller/solar panels??

going forward, i suggest you change ur charge controller to 60amp mppt...hoook up the battery bank properly to it...and observe the system for a while b4 changing it.

what is the voltage rating of ur charge controller?
what is the input voltage of ur inverter?
are ur panels 12v or 24v?...how are the connected?
send us a picture of ur charge controller screen during sunlight..lets see the harvest data

You sound like a professional. Because of the stress and the money I have invested, I decided to go online to study. I noticed that some guys connect only the solar panel to the inverter via solar charge controller and they only have power when there is sunshine.

Anyways I have a 12v batteries 150amp. I screamed to my installer that I need mppt and they said mppt will cause overheating/overcharging or something else but they discouraged me. My Solar panel charges at 66volts but according to my installer, whose judgement I now doubt, said the controller regulates the charge to the volt of the batteries. Now my 150amp batteries seems to operate at 50v. I also have an external charger that tries to boost the batteries but immediately I load, it drops to 50v.

I am tired and frustrated. I currently used less than 10 percent of my inverter load and doing my calculation that is 500watts I believe

So far you've given out following info:

1) Number of batteries
2) Number of panels

Please shed more lights on this:

1) Type of inverter and voltage setting
2) Wiring arrangement for your panels
3) Wiring arrangement of your batteries
4) Estimated load - your daily total energy requirement
5) Pictures of panel installation and orientation
6) Pictures for your inverter and controller

@ Saipro
Can you please explain with calculations why you think the panels are inadequate for the battery bank.
Maybe there is a mistake in my calculations.
By the way, the panels are all mono.

Saipro:


As much as I admire your setup, upon closer inspection, there appears a fundamental flaw (pretty common in RE): your PV array is somewhatinadequate for maintaing your bank - unless you plan to sparingly draw energy from the battery bank. Even then, you'd have to take an entire day or two to charge back if you somehow draw up to 50% DoD.

A given however, is the fact that your array is capable of supplying enough charge current to keep your batteries "happy". I'm quite curious as to the application to which this setup would be attending to. You could PM me if you'd prefer to keep things discrete.

PS: Pardon my overly enthusiastic and unsolicited comments but my inferences are based on the fact that your setup looks like something meant to power equipment with either high-surge starting current or equipment with steady but high power consumption.

Frankly, that would be impossible at the moment for I have no idea of what your loading (power draw) of the system would be and that would be fundamental to any equation I might try to bring up. My assumptions are solely based on your heavy setup being probably meant to back up some heavy equipment. It's easily and quite possible that drain would be minimal (emergency backup lighting to a facility in the event of power failure and to fill in the interval before the main backup power comes on) or you have other means (dedicated chargers) for boosting the batteries.

Don't let my pessimism discourage you as I like to over-prepare for eventualities that may never arise. I'm by nature both very cautious and a perfectionist. Not the very best of traits in the open field. Gimme an idea of the purpose of your setup and I'll give my own view (which might incidentally tally with yours)

Well, all I can tell you is that the panels are capable of charging the battery bank to full at 50% DoD.

Solar panels
12 x 275W solarworld panels = 3300W
12 × 250W Renogy panels = 3000W
Total of 6300W x 5 hrs of sun per day = 31500WH/day

Battery Bank
8 x Trojan IND17-6V =48V 925AH @ 20h
Total Capacity of 48 x 925Ah = 44,400WH

As you can see, even if the panels are producing 25000WH/day....still enough to charge the batteries at 50% DoD.

Inverter
Xantrex XW6048 6000W 48Vdc with 100A charging current. This inverter will charge the battery bank to full within 5 to 6 hrs provided the bank do not go below 50% DoD.

Please let me know if you have any other questions. We are here to help each other.

@ saipro, this is exactly what I told u during my last visit to your house.

I remember saying he definately intends to maintain 50% dod at every point in town. And if by chance the bank is drained above 50% then... the xantrex has a super charger that can do the corrections in few hours with a generator and this is only needed only once in a while.

Sorry, been really busy.
My husband has corrected me on a few points (he's not on naira land).
The panels are in parallel, the controller is pwm, my TV is 73w( 32 inch Sony Bravia).
I saw the figures myself ie the voltage and current figures on the controller when it was on. I hv attached pics of d controller, it is off at d moment though as it has been disconnected . also hv a pic of d inverter (cyberpower).
Tanks guys for d responses.

BEEN TRYING TO POST THIS SINCE LAST W...SPAM BOT WAHALA, HAD to use pictures

I enjoy this thread alot....just reading n looking at pixs is exciting. anyway let me drop some quick hints about circuitry


1. d farther your battery is from ur panels and d higher d current in ur cables, the more losses you get from ur panels

2. mppt is best suited for cold/temperate regions n high capacity setups. pwm charge controllers are not so bad either n are better suited for warmer regions.(personally I have a very small, in fact micro setup iv been using for ab0ut 2years now n still running. I built my charge controller myself n as basic as it is in operation, my not-so fairly used batteries lasted a year plus before I replaced dem.)

3. d higher your panel volt difference from ur battery bank voltage, the less the amount of power harvested from your panels.

4. lastly, for really large capacity and longer usage you can look into gravity operated hydro systems. This system uses potential energy of water instead of battery to store energy, and is touted to last longer than batteries would.

weldone guys!

attached in word, an admin can help copy and paste the info.
