lol, dont understand why we are all arguing.
dude said he has 1 32 inch tv..lemme assume its lcd = 150w
1 home theater = 80w
1 laptop = 60w
1 bulb = 20w
gotv/phone charger etc = 20w
total 370w
total energy is 12v 200ah batt = 2400wh @ 50% dod = 1200wh, factorin in efficnecy factor and losses = 1000wh

so his 370w load will last roughly 1000w/370 = 3hrs!!!

am really pissed that u guys are arguing over shit like this, so if this guy is ur client u will advice him to go for 1 battery??

advice like this has put many people off the solar/inverter or RE thing, as where u want to save money for him by suggesting a lean setup, it ends up back firing as the system fails to deliver, as client goes away believing that inverter doesnt work.

i have friends who people like you hv adviced wrongly and they ended up regretting and having to upgrade thier system at a very high cost within 2yrs. if u are well grounded in something, a simple glance tells u what may b wrong, i dont hv to bother abt dod/wh, usage time etc...for such an elementary scenario the OP posted. my motto is KISS = keep it simple s,tupid

earthrealm:
if u have money , go for 2 x 200ah batts or 2 x 150ah battery,
using a single battery will put much strain on the batt, it will pack up b4 18months, and u may need to buy another batt

imagine driving to lagos from abuja on a 2cylinder , 4 cylinder and 8 cylinder car, while each car can make the trip, over time, the 2 cylinder car will likely breakdown first, while the 8 cylinder will serve u many many yrs...same goes for batt n inverter system,s

Sir please how much do you think I will need to install solar power to my self contain apartment? I have a 32in LED tv, a ceiling fan, and electric stove and a small chest freezer.

VOC : 37.5×4= 150v

Barezzi:
Dunka, that 145Vp is too close to 150Vp!
This na just wet season, what happens when dry season reach?
Your cc will be damaged if that voltage level is breached!

bigrovar:
Brothers. I need help/suppliers/suggestions for a 15KVA / 20 KVA inverter system. It is required for a High Performance computer setup that requires pick load of 9900Watt of power. This is meant for highly rated computational science research. High end (US, Europe ) product will be considered.

I am now thouroughly confused. I had a lightning strike again today. MY SUKHAM 12V INVERTER ATTACHED TO A BATTERY BUT NOT SWITCHED ON OR CONNECTED TO THE HOUSE IN ANY FORM CAUGHT FIRE!!! IT WAS A COMPLETE STAND ALONE SYSTEM, REDUNDANT AND NOT IN USE IN ANY FORM. What to do now o

mank1234:
Hello house, what is the AH as seen by 24V input inverter in each of the following case:
1) 2 200AH 12V batteries connected in series to make it 24V
2) 12 200AH 2V batteries connected in series to make it 24V
?

Which is a better setup in terms longevity of the battery and efficiency?

DUNKA:

Various Solar Accessories

Total Price:

I am a complete novice in this how I was able to set this up was what I gleaned from here then gathered all the accessories over a period of about 2years.

To this end let me hail all that have contributed to this thread but most especially GeorgeD1 who invaluable early contributions really pushed me down this line. Though it seems he no longer active on the forum and to Chris81964 whose background advise has been invaluable.

I also give a shout out to all the suppliers of my solar items namely CoOgumo,Richmon,Gennextec, and the one and only Chief Marketer Kiekie I will say that I have never met anyone of them in person and we have transacted seamlessly as payment is made and items sent no long story. Anyone can deal without fear.

Though a novice let me give a little advise if it can help anyone. Start small as you will be discouraged if you try to buy everthing at once.

For the inverter please go for the high end products Magnum, Scheinder,outback,victron,SMA, as all the ogas in the house use them so that should tell you something.

Do not buy the cheap Chinese,Indian and Korean inverters. If constrained by funds go for Prag or Voltron.
For the charge controller also go high end if possible with Outback,magnum midnite solar, morningstar etc. Being the top brands.

For Batteries I prefer flooded due to its resilience and particularly for the ones I am using the electrolyte indicator is a God send as you can easily see when the cells need topping off (newbies take note) . Good value for money.

A word if caution if you are using flooded batteries u should note that the popular Axpert inverter is limited to 58.4 charge which will undercharge flooded batteries and will kill them. It also cannot equalize flooded batteries you will need a good quality CC to perform that for flooded batteries. I know because that was my 1st inverter before I now went for the Outback. Also note some branded inverters advertised I see here are Axperts so you have to know the right questions to ask. That been said it served its purpose for me and now will dispose it or keep it as my back up inverter for when there is any issue with the Outback.

I strongly recommend that you protect your system from lightening strikes by using surge protectors on both the A. C and D. C sides of your system. Thank me later

Please do not ask me any technical issue as I just got the items and paid for installation.

Also do not ask for price as with the fluctuating dollar rate prices are totally crazy now so whatever I tell you will not be correct as of today. If you do not believe me agree for an order with Kiekie and you do not transfer immediately by the time you come back after a week you go know say khaki no be leather.

Solar is the only way to go as in the long run it is cheaper than the unreliable grid which makes running g generators very expensive

As a whole get the correct information before you start. My last word of advise change all yr light bulbs to low wattage LED bulbs. You will thank me later.

Installer are still tidying up the install. Will post the internal set up later.

I don't like dragging issues, but I have to say 1000 watts panels to 2* 12v 200Ah is a waste

shamecurls:
Thanks

1kinggy:
The sticker showed that the freezer consume 1.15KW in 24 hours. He would need to limit the use as this equals the rating of his inverter.

Hello Experts,

I run a 24V 1.5KVA Luminous Zelios inverter on (4) 12volt 200AH batteries connected together.

When my inverter Back-up time is at 00Hours.00Minutes, My inverter still runs for like 12-14 hours more.

-Could it be that the battery bank is too large than the inverter specification? or What else could be the problem

-Also, Can it be said that am over working the inverter as am using it to charge (4) 200AH 12V batteries

Trippledots:
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!

Yay! finally!

For months now I've noticed that the number of chickens in my poultry reduces by one every morning till it finishes... I've been wondering what's behind it not until tonight when I heard these chicks making some unbearable noise and on getting to their cage, I saw this long snake hooked to The net of the cage!

Ignore my grammatical blunders, Anxiety yi noniiiiii!!!

pranil:
|So my system functions exactly reverse of that you have designed NO changeover at all infact no interruption to power unless the system is taken offline for maintenance. in such a case I by pass the inverter circuit to grid /main gen by using changeover cicuit

Use to use Mobile one 5w-30 but tough times for me to use Shell which is actually recommended for my Hyundai.

Saipro:
Kindly explain the above quote. My presumption is, charge controllers don't create power. Let me put it this way, energy generation by the panels would be the same in both scenarios hence overall power (assuming low light conditions). The difference should be in output voltage and current, not overall power (again, assuming low battery charge). My understanding is, the greatest difference would be while trying to charge a nearly full bank under low light conditions.

No harm meant, just clarification .
