2200VA UPS APC to Solar Inverter

Today I bought an old 2200C APC UPS. It costs $ 100. I will convert it into a solar inverter. In this video, I will clean it, Add a battery connection, reduce the no-load current and test its capacity. In the next video, I will add a large capacity MPPT charger, Automatic switches and protective devices.
All my projects are free, I design them on EAGLE 6.0. I uploaded it to Google drive. You need to use a web browser to download the file and open the file with winrar software (extract) on the PC. Open schematic file (.SCH) and PCB file (.BRD) with EAGLE software.

[@kashifhussain4246]

How you claim, it works as solar inverter. On other way you connect the batteries on load test..... Connect the solar to it and then load test....variable solar voltage and current not support apc ups then it shutdown immediately.

[@winifsan3873]

[@ambersmith6517]

[@leviahamefula3994]

Why do you calculate the no load output with 48v? Is the UPS 48v or 24v?

[@alexpescaru]

When you added that filter coil to reduce the no-load current, how did you calculated the number of turns, wire section, type of core, etc? Is there any math behind it or in this case was an arbitrary choice? Thank you.

[@1brasov]

Thank You for that excellent video!!! I did a Cyber Power 1900 a few months ago, not nearly as neat as your example here. That was great how you figured out how to reduce the idling current of your inverter! And wound your own inductor!! My UPS draws 55 watts at idle, and I always felt that was a bit high. I may try to duplicate your idle current fix on it. I run my ups output into a 6 circuit generator transfer switch. It is great to have when the power goes out .All I see is the 20 Milli second light flicker when power goes out. Its easy to miss that! It takes care of power outage with no intervention on my part. I did not know I have a brother somewhere. Thanks for posting your video!!!!

[@andre-le-bone-aparte]

Just found your channel. Excellent Content. Another subscriber for you sir!

[@DimitriPappas]

Cool bro! Wish I understood how that inductor works to lessen the load... It has no losses while load applies, or affects waveform in some way? I'm not sure why some people are hating this video because you didn't build it yourself. At least you bought it used, and refurbished it. If they are so smart they should make their own videos. You're the one with all the views and subs. Good job !

[@PhdHung]

I'm just an amateur, I've seen Chinese inverter (use EGS002 modules) use an inductor at the transformer primary. and the no-load current drops. So I tried it. Thankfully it worked fine, The waveform did not change, it is still true sine. Conversion performance increases.

[@udisami9856]

@@PhdHung The inductor serves to filter out the modulation frequency (in the khz range) that the transformer core reacts to by converting most of it's energy to heat due to the hysteresis effect of iron which can't handle such high frequencies, resulting in early core saturation and an increase in the magnetizing energy. A well made transformer that has been specifically designed for the inverter will have enough leakage inductance to filter out the modulation frequency (on the expence of size and cost) eliminating the need for a separate input inductor.

Mám otázku, testoval jsem 3 ups a po zapnutí na baterie bez synchronizace ze sítě všechny pracují na 60hz. Potřebuji 50hz. Jak je možné že Vaše ups pracuje okamžitě na 50hz?, je nějak upravená? Moc děkuji.

[@OleBrinch]

I have had an APC SUA2200 running for 6+ month on a 80 kWh diy powerwall with no shutdown. Works fine. I have idle losses lige yours. The filter interests me, but I have gotten hold of a toroidal 3000VA transformer from another brand of 3000 VA/48 volt UPS that has blown electronics. I also got hands on a APC SUA3000 and I think I will swap trasformers. It seems than 90+% of the losses at idle is from the transformers which get pretty hot. The MosFets never get really hot. You have a new subscriber :)

[@PhdHung]

Yes, I think if you replace toroidal transformer, the efficiency will be higher. I also replaced mosfet irf4710 with irfp4110. it is much stronger.

[@philblanchfield]

What happens if there is a short across those 2 completely exposed terminals that you put on the back of the UPS? I am thinking that those skinny wires on the batteries will light up.

[@prashanthb6521]

I wish I could see the general outline of the circuitry. I did not understand where you connected the inductor and other few details.

[@walleywalley]

you just converted it from no battery pack model to battery pack model:)

[@kaushikreja]

Good work to reuse old ups. One question in mind. How did you stopped ups charging mechanism? Or you just have kept disconnected grid input for ever?

[@headlessxp4948]

The UPS uses its main transformer to charge the batteries so you cant really "disable" the charging circuit. The way I did it is to just connect a diode between the battery and the UPS. But dont use a regular diode! With a regular diode you have to much voltage drop and therefore power loss. Use some high quality, low RDSon MOSFET, something like multiple IPP023NE7N3GXKSA1 and the LM5050 IC to build an ideal diode. With such an ideal diode you should be able to achieve about 10W of loss max at maximum load.

[@adiwickx]

Question number 1 where you connected solar panels? 2nd main grid should be taken out from APC 3rd how you are going to charge batteries? We need mpt solar charge controller 24V ?

[@piljaga1]

I have 3000VA APC UPS and want make solar inverter too. But it cant do first start wirhout mains (if it is solar inverter there are no mains at all). If I connect mains it starts, then disconnect mains UPS keep working on battery. Which element checks mains existance condition? I should remove this element. Can you help me?

[@ambersmith6517]

A year or so ago I tried several different chokes it helped very little to none I concluded that the losses was in the Square Transformers I plan on building a toroid for it but I didnt know or check the voltage of the other wires if I remember correctly it has 4 or five instead of two Do they need the other wires

[@gumnahs]

The wire tapping will be like 0,170,220,240 and small two wire loop around 25v for charging.
