Since your runtime requirements are small, the issue is VA rating.

Look on Ebay Ireland for refurbished APC SmartUPS 600 or 1000, just
make sure the batteries with it are new.
You can always sell at nearly the price you paid when the problem is
fixed.

Thanks. The only Irish-based one I can see at the moment is a 1500VA -
start price 1 euro - buy it now 400 euro - lots of phtots but no mention
of battery condx.
