Dear Austin,
Some more inputs on types of UPS systems. Broadly we can classify ups in two
types, one True On-Line Double Conversion UPS and other Off-Line UPS system.
The term Inverter became popular for Off-Line UPS system used in domestic
application. The output of a off-Line UPS can be Quasi Sine Wave
(Trapezoidal) or Pure Sine Wave. Nowadays, the Inverters with Sine Wave
Output are available. So in my opinion, the same can be used.
Anyway, Hi to all group members,
I am Milind Joshi, father of a 12 year old girl, Nupur - VC. I have been
associated with various organisations working for VC.
Being an engineer by profession and had entire career in Power Electronics,
I couldn't resist from putting in my comment. So. . . .
Good to see such interaction on various topics. Enjoying... Nupur will
certainly join the group .
Bye.
Milind Joshi.

Dear Austin,
Charging a battery from the square wave electrical output of an
inverter will definitely be bad for both the battery charger and the
battery of your laptop. The harmonics will heat up electronic
components and lead to shorter device life.
To keep your laptop and its battery and battery charger safe, you might
have to use expensive harmonics filters. Better way is to charge from
the grid or invest in a sine wave UPS.

Dear Austin,
I have a feeling that your figures and units are a lil mixed up.
(Battery is usually rated in VA, for example.)
Whatever it is, it is advisable not to use your laptop's battery
charger
with the output from your Inverter. It is, of course, a different
matter altogether if the device is an online UPS with sine wave
output,
in which case the voltage regulation is quite good.
Hope this helps.
