Question for the more technically minded folk that read these pages.


I have just been given a 1000RMINET U.P.S is it possible to use this with a wind turbine set up.

Turbine - Battery Bank - UPS- Load.

What I'm figuring is if I get a turbine to charge a large 12v battery bank, then connect the battery bank to the ups instead of its interior batteries I should have a system capable of powering lights, portable tv etc.

Feedback welcome.

Sundowner.

PS Ghurd if you're reading this that company didn't come back with a quote just pages and pages of motor details.

Spot on Sundowner,

You've basically got a cheap pure sine inverter. Do check what battery voltage the UPS runs on though.

Cheers

Del.

I am here. It was easier for the guy to swamp you with PDFs than figure out that a 100 would cost too much to be worth it to buy. Then figure out your price.

This is with a US twist...
Didn't look at that particular UPS.
Most are Not true sine-wave. Every one I heard about is terrible in its efficiency, worse if the % of max load is light.
Some won't "boot" if not supplied with the grid first.
Some "scream" the whole time the grid is not available, until they shut down from under-voltage.
Some have a bypass, either a method of pushing buttons or a re-set, to stop that "screaming beeper".

Not all is lost.
If the inverter is only needed 10 minutes a day, then a re-did UPS is fine. Maybe a saw is needed for a minute, and the UPS is 1KVA. Fine.
I haven't seen one suited to 50~100~500W for a long time in an RE situation.

If the UPS is 12V, and the RE is 12V then it will work. Mostly.
The RE charges the batteries. The UPS feeds the inverter.
The RE still needs a controller of some type.
I know a guy using one like that. He disabled the reset functions, and beeper (tore it out with pliars). The solar and wind charge 12V batteries. He turns the UPS on when he needs "Lots-of-AC-watts". He doesn't use much AC for very long.

Here, a 1,000VA UPS is usually free. It costs less to replace the entire unit than the batteries inside it.
Here, a 1,000W inverter is worth far more than a free UPS.

An UPS inverter is best thought of as a temporary and/or short duration inverter.
If it is intended to feed a CFL or 40W laptop, then it often wastes more power than it supplies to the device.
If it will supply a saw for 15 minutes, twice a year, then it is a great deal!
Everything has a purpose?
