Sorry to hear the news TEL, losing a long owned pet is like losing a family member especially if you have loved it and looked after it for a long period, chin up Mate, like you say She had a good life and didn't suffer in any way.
What you are after Mate is a "no break set up" whereby the mains fail UPs takes up the load until the standby generator starts and sincs in taking up the load, not a simple installation.
I did 12 month on top of Mt Olympus in Cyprus, not nice as it sounds, and if you have a young family it's hard to take any lengthy times away from your loved ones, think long and hard before you commit Mate, it ain't all roses believe me.
