lol. Technically, the TV is a DC TV.

except for appliances with heating element, and those with Alternating Current (AC) motors, most gadgets are DC hence there's always a step-down somewhere to convert and drop the 240v AC down to required voltage.

For the likes of [desktop] Computer CPU, TVs, etc, which require multiple voltages for different parts, complexities increases.

Hard disk requires different voltage, from LED / LCD display, even the TVs display screen requires a different voltage from some other parts of same TV.

At end of the day, the highest ain't even up too 20-volts yet you invert to 240-volts, only to drop to less than 20-volts incurring unnecessary conversion looses.

Have seen low-income people who spent money acquiring Inverter to power things I could just have skipped the inverter for, and spend that money increasing capacity and quality of other things

clevermugu:
if u believe that capacity is real, then u can believe anything if they attempt using smart bms on thier packs, like most in-house guys here does, they will be caught pants down in thier capacity inflation deceit.

A lot of us ain't ready for such discussion.

Let me give you the response you so desire - what I meant is even God can't easily argue with me with no solid evidence on something I'm so so sure about. In order words, I'm so sure the color of my 5,000 Litre GeePee tank is black, if you coming to tell me it's RED, you better have prove strong enough to convince me even if you are God himself.

If you see it as chest Beating, no problem.

na una go start argument expecting the other party to keep mute so una go win. Me go follow you enter gutter if I choose to be silly enough ELSE una go win in discouraging others to think outta the BOX.

Me sef be installer wey a lot of una dey claim. I have seen a lot of so-Called professional solar installers who don't use Solar themselves. I first became a core Solar user as far back as Jonathan regime when I started running 12pcs 300-watts Solar panel, which I even installed myself.
Then through convincing people to use solar to reduce reliance on NEPA, and referrals, I slowly started doing for others.

A lot of us lack critical thinking ability hence must do things the way we were taught even if it ain't the best way.

Of course from my comments, it's easy seeing I am not the kind that waits on God to make use of the brain in my skull.

Shalom sir.

On AC vs DC in solar setup

I have seen a lot of argument about bypassing inverters and using the DC that comes from your battery directly. The argument is that it is efficient since it bypasses the inverter consumption and the loss due to the back and forth conversion.

The problem with this argument is that it is not novel. In fact AC and DC competed for approval when electricity transmission was to start. AC won for many reasons. Anyone interested in the AC vs DC drama between Thomas Edison and Nikola Tesla can read it up online.

The best situation with bypassing the inverter is if your appliances are in the voltage of your battery. That way, there will be no need for any kind of conversion and there will be no loss. In fact this is why a lot of DC appliances were 12V and why most early solar setups were in 12 volts. But 12V is inefficient for high wattage appliances because you end up with high current. The cost of cable to handle such current outweighs potential savings. Moving AC from 110 or 220V to 12V also create greater losses. That is how higher voltage equipment became popular.

So, unless you are using appliances that are in the voltage of your batteries, you still end up doing conversion. AC to DC conversion and DC to DC conversions both results in loss of efficiency. So, the idea that powering your equipment with DC is somehow better and more efficient than AC is not a universal truth. Your mileage will vary based on the efficiency of your conversion. With some inverters doing better than 95% efficiency, the argument for any kind of DC-DC conversion becomes difficult to sustain.

In addition, DC suffers from the indignity of voltage drop over some distance. From my power house to my server room (about 12m), my 14V source drops to about 11V. In the days of Lead Acid battery when the battery voltage itself can drop to below 12V, my 12V routers used to shut down or become erratic due to voltage drop. I know I could have mitigated the drop with a thick wire, but that will be costlier than buying a sachet inverter to power my routers. So, if you have a normal sized house, DC is not going to serve you well unless you are going to put buck converters in every corner of your house which will increase your costs and increase power loss due to conversion at multiple points.

Ultimately, inverters provide better solution than messing around with DC-DC conversion and messing with your electronics.

This is not to say that there is no place for using DC in some situations. A few of my gadgets that are in the power room are powered directly with DC from the batteries. My system is 48V so, I got some 12v and 5v step down to power some load including a router. The advantage of that is that if your inverter goes down for any reason, you may still have access to your network for troubleshooting.

One time I travelled and my inverter went into protection mode. My people panicked and called me. Because of the things powered directly from the battery including the sachet inverter in the server room, I was able to reach my system, saw that it was the inverter and asked them to restart it.

you've spoken BUT I want to inform you that from the start, i have made it clear there's a place for DC.

In fact when you use inverter, you could still reduce load by using DC / low power appliances.

People are advised to use energy saving light bulbs while on NEPA / PHCN so their prepaid meter unit doesn't finish on time.

So you see, where you are on Solar, or using prepaid meter on NEPA/PHCN, to keep cost low, and enjoy longer runtime, you need keep load low.

Abi why do you think we now have Air-Conditioners, and refrigerators advertised as inverter friendly ?

Between 2 PEOPLE using a 48-volts inverter system, if one of them use low energy 2HP Air-Conditioner 
for 3 hours, while the 2nd person uses a normal 2HP Air-Conditioner for same 3-hours, who do you think would 
enjoy longer runtime all things being equal ? of course it's the person using energy friendly Air-Conditioner.

So even by using inverter system, you could either buy energy friendly appliances, or convert those you have to use lower power

As for power drop over long distance, of course should you know what you doing, it's no issue.

When distance between Solar panels and Charge Controller is long, I prefer High voltage, Low current setUp so drops are minute which is same thing power generation companies do e.g NEPA / PHCN .

In my home, I have several Solar setUps for different uses. On the roof, I have just 2 sets of Solar setup but for my mini Sever room housing about 9 Computers including 3 units of Dell PowerEdge T630 and HP ProLiant ML30, I have 4-batteries connected in parallel to make 12-volts 800AH battery which powers the server room.

Now I tapped from Solar Panel which already is connected to another inverter far away, and routed it to an MPPT epEver chargeController which has a 12-volts output from one of it's auxiliary ports.

It's from that 12-volts auxiliary port I draw my current I use in powering things such as my Display monitor, and low energy sensitive gadgets.

As for the high power CPU servers, I have a small circuitry to smoothen the current from battery to ensure I don't get dirty voltage and unnecessary trip-offs. I didn't draw directly from the chargeController's 12-Volt auxiliary port to avoid damaging the device as the draw would be too much.

that way, even if I leave the system unattended, it wouldn't drain the batteries should there be no sunLight for extended days.

Of course the power Packs of the server Desktop computers have been ripped off, and instead, I took note of the different voltage points/rails on the motherBoard and gave it what it required. that way, the highest it needed was 12-volts.

The first time I did this, took me a lot of time BUT subsequent times, it's super easy and quick because I already know what to do.

In turn, I ended up saving on lots of Solar panels and batteries because those Servers dey gulp power no be small especially when running performing intensive tasks.

The batteries are about 5-feet (had to measure to be sure) to the Computers, and na original Aluminium cable wey I use Ooo.

I obviously didn't tell you the current batteries were actually decommissioned hence not brand new and I've been using them for almost 2-years now and they run 24/7 as per say server no suppose dey down.

I don't mind spending a couple of hours or days to come up with an idea that would save me lots of resources for several years. And should I get someone asking for something similar, it wouldn't cost me the time it cost me the very first time I came up with such idea.

that's it. Bye for now make I work small

Why do you have a 5000litre Geepee tank, you dey rear fish??

dellabella:
Yes, I ordered two aurora batteries from them and they shippedto Abuja same day. I pickedup the next day.

I've done business with them before. I bought Felicity inverters and they had it installed for me. It was quite easy. I'll recommend them.

bassdow:

@Olumighty123 what's the update on this please ?

Turns out a cell in one of the batteries had been damaged, changed battery and its all good now.

Namzy:


Get a 120 amps relay

Got any schematic on how to rig it?

Which of the two power source has priority? Or no priority here? By priority I mean the one you'll want to use should there be power in both.

Thanks a lot. How much does it sell for?

Love to see lifepo4 prices coming down. This is like 170k per kwh. Even cheaper than what you'll get from our in-house guys here.

Lol

Prices of cells are dropping heavily from China too. If not for exchange rate, the fall would have been more drastic than what we currently see

kristien4:

have got 3pcs of 3,000 litres, 1pcs of 5,000 litres and another 1pcs of 2,000 or 2,500 litres.
As for why I get them, na because I get plan for them.

Also, I no get generator and to rent generator for 1-day costs 5,000 naira even if you use it for only 2-hours.

Me dey use my own complete because I dey pump from Morning till evening.

That way, water no go quick finish, and nothing concern me with maintenance wahala; not even to change oil sef.

My own na to just fuel am and leave am dry as I meet am.

I'm yet to be certain if I would need rent generator for pumping water more than 2 or 3 times a year. I never really calculate am.

I bought them all USED, except for 1, they're all Rubber (those old rubber Oooo) and I'm still open to buy more at good bargain if available.

I know I could use solar but me no wan stress my setUp abeg.

Olumighty123:

One of the things I thought earlier. Same happens regularly in laptop batteries. A single cell in a string could render the entire thing useless.

I want to believe even that bad one could be refurbished. Probably change the electrolyte and charge seperately.

Glad you had it sorted
