Basically, you need a UPS with at least 150VA/Watt inverter capacity, and a 50 some amp/hour battery to last 5 hours. Depending on the devices, I might see if I could direclt power them from the battery. For kicks, I'd get some solar planels to alleviate mains power use.<a href="http://www.popwebshop.com/recreation/"> classicsat</a> Assuming you mean a mains powered load.

If the devices can run off of 12 volts DC it would be better to run them from a large battery with a charger attached. Or, if you need 120VAC, a small inverter/charger hooked to a large deep cycle battery. That would pretty much be a big homebuilt UPS.<a href="http://www.businessbrokersguide.com/san-diego-business-broker.htm"> Nomadd</a> Most UPS’s only have a 7 amp hour battery which would only run those two things for about 45 minutes. 5 hours would take a system with a battery almost as big as a car battery.
