Long term suoer inverter users, pls whats the experience like? Being seeing some cheap solar packages including it and wondering is its use a smart move or just for cost cutting measures. I feel the modified sine wave it produces is harmful esp to led tvs and fans?

While some people are able to get away with using MSW inverters, most people don't. It damaged 2 of my standing fans when I started my renewable energy journey, plus most of your appliances will keep making a humming mentally-unsettling sound.

To be on the safe side, just get a pure sinewave inverter.

Good for :
regular led tv
Rechargeable fans
Lights ( regular)
Charging

Bad for:
Smart tv
Regular fans
Flourecent lights
Voltage guards etc

Pls which would be more efficient charge wise? 4 150watts paired to a pwm or 2 300watss paired to a mppt charge controller for a 12v 200ah battery?

If u can get a genuine panel the 300w will b a better option cause if u won upgrade nah to just buy more 300w panels. A huge percentage of those 150w panels out there won't give u 150w.

i would want to say the PWM controller but go for the MPPT charge control for the sake of future upgrade and efficiency, you wouldn't miss it.

@Drgreatone , just understand that it's PureSineWave inverter that produces exactly quality of light that PHCN / NEPA supplies. Output of Modified sineWave ain't even good for small electronics sef

To me, PWM would work in both scenarios. MPPT mostly is beneficial when the gap between the outPut of your solar Panels vs capacity of your batteries is very wide.

Let's say you actually needed just 2 Panels for your battery, but you had 4 or more panels, then MPPT would be very very useful for you, because PWM would just do the math, and throw away the rest in form of heat.

Once again, if you have the funds, buy MPPT else PWM is just fine in this scenerio

Tubular batteries does what they call voltage sagging. It goes to fully charged at 27.1~ 27.5v floatation. After the sun goes out it start dropping to 25.3v (still fully charged) stays there for a while and when you put load on it, it further drops to 24.8v. it can say on 24.8v for hours depending on the load before it continues its voltage drop. So for a firm response what is your voltage at 75 or 85%?

Is this applicable to GEL Batteries too?

Not entirely true sir.

temi4fash:

Yes, but with slightly different values.

issue is, most of our so called Nigerian engineers, are only good at copying (verbatim) without improvements.

why invert 12-volts all the way to 240-Volts and above, only to have it steppEd down to as low as 6-volts or lower sef.

My 32-inch TV/Monitor is rated 20-volts, I run it directly on 12-volts. of course when you drop voltage, current would UP a little.

Before now, I have to open a TV, reWork it's power panel, and Create alternative port for lowVoltage which means a TV of 240-volts, would end up using less than 20-volts

Same with my Laptops, and Desktop PCs, my laptops are run directly on 12-Volts with no amplification from me.

Those that gets stuborn enough, I either tap the 12-volts directly from chargeController 12-Volts output (I tend to avoid taking directly from battery so as NOT to overDrain the battery when I'm not monitoring, and also to get clean supply, devoid of noise) OR I BOOST the 12-Volts to 19-Volts and supply it direcly to the laptop's power port and the lapTop would think it's receiving power directly from PHCN / NEPA / etc.


and I am not even an Elect/Elect graduate Ooo. I don't even have diploma in anything of such. Just childHood knowledge.

Hence reason I get disappointed when I see those who give themselves fancy names, with papers to back it up, not thinking out of the box.


All my Fans are tokunbo rechargeAble fans I bought for less than 7,000 naira at Arena in Oshodi, lagos and I removed all the converters inside it, and supply them 12-Volts direct.
those with weak Stands (since I bought them tokunbo), I convert them to wall-Fan, and I even have 2 rechargeAble ceiling Fans I converted sef and with that, I have no issues.

When I have very weak Solar-Battery, I don't just Dispose them off, I redeploy them to another position.
That's I have 3 sets of Solar panels - those that charges brand new solar batteries, those that I use for some other things, and those that charges weak / almost dead solar batteries.
Now those weak or dead solar batteries are the ones I use in powering all those FANs (I've got 9 presently), and (LED) Lights, made out of rechargeable Torch-Lights. I keep on using them till they're 150% useLess to me, then I look for those who buy them as scrap.

The only thing that really uses full light in my apartment is the chest-Freezer and I power than only during the day when the sun is out.

Even my outDoor Tv antena, I had to open it up, remove the transformer and resistor inside it, and replaced the Power-Cable with USB cable. Since the transformer is 6-volts output, I supply it either 6-volts or 5-volts from the USB port from back of my TV. Even my laptop USB port sef powers my outdoor TV antenna that has rotator. Only thing is - when I supply it 6-volts, when I press rotate button, it would rotate, BUT when I supply it 5-volts, it doesn't. well I rarely have reason to rotate it sef.

Now that's how far I have gone in converting things.


Imagine If I choose to open a shop, na to dey build UNIQUE power solutions, not all these followFollow things being sold everywhere

Interesting, nice idea. The shop is long awaited.
But this means you run surface wiring around your house for the 12v installations.

abbeymighty:
please how gan i test the actual watt of solar panel

The most reliable way to get an accurate reading is to measure the current with a multimeter and multiplying that by the measured voltage.
But make sure the multimeter you are using is rated for the short-circuit current on the solar panel and don't keep it connected for too long. You also have to select the appropriate range if you're not using an auto-ranging meter.

Using a charge controller (pwm or mppt) might not give you the actual power that your panel can output. There is also a dedicated tool for measuring this.

Thanks everyone for the contribution. Want to set up a low cost 12vsetup for my mum thats why I asked abt difference in pwm/mppt charge. The pwm seems cheaper and within budget but want to be sure if 4 150w panel or 2 300w panel wud give same results with it.
Would also need recommendations for an efficient pwm charger too? Thanks

Pls which good tubular battery can you pls recommend for me below 200k

karte is very good and pocket friendly

Two 300w panels are better

If upgrade is not in the plan, Stick to PWM it's more efficient with 4, 150w panels.

What's your thoughts on Gel batteries everyone?
Good morning all.

What quality batteries, would you suggest instead sir??

bassdow:


Oga I beg you don't do this. there's no good brand New 200AH Tubular battery in that price range. Except you looking for something much lower in terms of capacity and quality.

The cool thing about buying cheap Solar batteries, whatever money you think you've saved, would be spent later in multiple folds.

Rather than buy 5 pieces of low quality batteries, kukuma wait or buy fewer of higher quality batteries

[size=8pt]Very shitty. Buyers' beware. A friend of mine got 2 of these inverters and they have both developed faults. One was repaired at cost. Stay away from them. And they are terrible for lithium. You can not program them.
