Hello everyone

1...Can anyone explain how to wire/connect small fan to 1.2kva UPS?

2...is "single" 12v 200ah battery OK to be powerred by a 1.2kva 24v UPS?

I think the company(GxQ) is no longer in Nigeria bcuz is now Kamicare.. Which they have higher system like 2kv, 3kvs etc

Can a Modified Sine Wave Inverter Damage Electronics??


You went shopping for a pure sine wave inverter for your camper so you could run your electronics while you are in the wild. You ran across a modified sine wave inverter at a great price, but you've heard that a modified sine wave inverter can potentially damage electronic devices, and you need to know the truth before you make your purchase.

There are only two types of electronics that you need to be concerned about when using a modified sine wave inverter: appliances that use AC motors and certain classes of delicate medical equipment.

If your electronics don’t fall into either of those two categories, then it's extremely unlikely that a modified sine wave inverter will do any damage. While a pure sine wave inverter is safe for use with a wider range of devices, the greater cost associated with pure sine wave inverters isn't always worth it.



How Modified Sine Wave Inverters and Pure Sine Wave Inverters Work:

Both pure and modified sine wave inverters take 12V DC from a battery and turn it into something that approximates the AC power normally available from the wall outlets in your home or business. AC stands for alternating current, which refers to the fact that AC power periodically changes direction. This can be visualized as a sine wave that gently rises and falls and swaps polarity instantly when it hits zero volts.

In pure sine wave inverters, the AC power produced by the inverter very closely matches an actual sine wave. In modified sine wave inverters, the polarity abruptly switches from positive to negative. The simplest inverters produce a square wave, where the polarity is flipped back and forth, while other modified sine wave inverters create a series of steps that more closely approximate an actual sine wave.

Since producing a modified sine wave is a much simpler process than creating a pure sine wave, modified sine wave inverters are typically much less expensive. The trade-off is that some electronics just don't work correctly or may even be damaged if they aren't powered by a pure sine wave.

Devices That Might Be Damaged by a Modified Sine Wave Inverter
While you’re probably fine using an inexpensively modified sine wave inverter in your camper, there are a few different things that you don’t want to run off a modified sine wave. Anything that uses an AC motor isn’t going to work to full capacity on a modified sine wave. Appliances like refrigerators, microwaves, and compressors that use AC motors won’t run as efficiently on a modified sine wave as they would on a pure sine wave.

In some cases, running an AC motor on a modified sine wave may lead to a buildup of excess waste heat that could damage the equipment. You’re probably OK to use these devices with a modified sine wave inverter, but you do so at your own risk.

The other main thing to be concerned about with modified sine wave inverters is delicate medical equipment. For instance, if you use a CPAP to help correct apneas when you’re asleep, you’re going to be better off with a pure sine wave inverter. Some CPAP manufacturers warn that you can damage your machine with a modified sine wave inverter, and others specify that the CPAP will work but the humidifier unit could be damaged.

Other types of medical equipment, such as oxygen concentrators, also need a pure sine wave. In these types of cases, you’re better off using pure sine wave power or looking for a unit that can be powered by DC without the need for an inverter at all if it's available.

Some devices suffer from unwanted interference from a modified sine wave inverter. You can power a radio with a modified sine wave inverter, but it may pick up interference from the modified sine wave, which could make it difficult to listen to.

No mind them grin

Well every one with his own opinion..


But one funny thing be say some people are using Modified Sine wave but the manufacturers only write pure sine wave for the body... tongue

Na so one guy say him buy solar charge controller MPPT 20amp for 10k.

donpata:
Guy, u are overexaggerating the whole thing. it's not as terrible as u make it sound. Run away from modified? lol. i didnt run away and i have been using it and no iss. Go to youtube and see people using modified sine wave on deep freezers with no issue whatsoever. People, it's just like when people tell u that charging ur phone on generator will kill the battery. So long as the power is stable, we are goood to go. That does not mean that if u got the money, u should not go for pure sine wave. The psw in itself is not exactly like what we get from public power but it's very close to it. Last last, if na tv, or laptop, get ur 13k msw inverter and flex. nothing do u

please how can get this inverter if it want to buy
I got it at Alaba Intl Intl Lagos
Science/TechnologyRe: How To Create A Locally Made Inverter With Ease by econome(m): 1:15pm On Jun 02, 2018
Let's take a look at this....

For newbies
Instead of buying battery charger, UPS, and fan to cool the UPS...
Charger 20apm 10k
UPS 650/1.2kvs 3k/6k
Fan N200
Wire N500
For 650va setup= N13700
Only you can value the stress in getting and putting them up together.. Maybe 2k grin

Why not buy Suoer 1000w inverter with inbuilt charger(Modified Sine wave) for only 15k, to save stress, plenty wire here and there on the ground and space?

...You won't need to buy inverter when you want to upgrade to solar system, will only buy charge controller and Solar panel..

The UPS inbuilt charger does not fast charge, could take months/years to fully charges.

And take note of this, UPS charger is designed to charge small battery(6a) inside the UPS, but you want to charge bigger batteries quick and easy..

That's the reason why you need a smart automatic charger..

Then use your UPS system as an inverter e.i ac output from your battery


Jayboi:
hello guys. why does one need a smart charger instead of the one that the ups uses to charge the battery.

Science/TechnologyRe: How To Create A Locally Made Inverter With Ease by econome(m): 7:26pm On May 21, 2018
In my findings..

to know the specified size of Charge control to be used is determined by the amp. of the the solar panel.

the formular is..

Solar panel Watts ÷Solar Panel Volts= required size of Charge controller
e.g Mono.panel 150w, 12v
150/12= 12.5amp.

So I rather am getting a 20amp charge controller. Its better to buy a big size of charge controller incase you need to increase size of solar panel in future, besides bigger size of charge controller do not have bad effect on the system.



Yemmyteespeed007:
I'm not yet into all these inverter batteries, I use lithium batteries and I have special controller for them.

but a 20amp charge controller is ok for 150watt panel.
Science/TechnologyRe: How To Create A Locally Made Inverter With Ease by econome(m): 7:10am On May 21, 2018
Having a "150w" mono panel what charge controller do you use?

Or what charge controller amp/va is recommended for

150w mono panel.
