Which one has best output power quality in terms of ripple suppression, better sinewave etc among these 3 APC models.

BX1100C-IN

BX1100I-IN

BR1000G-IN

[Teken]

None of these units are of high quality but if you had to choose one of the three it would be the BR1000G-IN. All three use Stepped Approximate Sine Wave not true sine wave output. The BR1000G-IN is the only unit that offers a LCD to provide you at a glance information / metrics where as the others offer nothing but a LED / Beeper.

The BX1100C-IN only offers a one year APC Warranty which should tell you the poor quality of this unit. It also doesn't offer any method to communicate with anything (APC Power Chute / Third Party) this includes the BX1100I-IN.

The other two models offer a 2 year warranty over the other. All of them have extremely poor voltage regulation while one of them offer no AVR circuitry at all. Only the BR1000G-IN indicates a reasonable surge protection / let through.

But this unit is extremely inefficient at 80-84% but does offer better transfer time of 8 ms / 12 ms maximum. If you're on a tight budget it would make sense to purchase the BR1000G-IN over the other two. If you can spend more than it makes sense to look into the Smart-UPS Series of UPS systems from APC.

In 2024 it makes very little sense in buying any UPS that doesn't offer True Sine Wave. Regardless, let us know what you decide to buy and why as I'm sure it will help someone else in your region considering the same.
