Inverter is fairly reliable as it is solid-state. It all depends on how long you want it for and what equipment is hooked to it. Inverter comes with 'Pure Sine Wave' or Modified Sine Wave'. 'Pure Sine Wave' inverter is very expensive for high output. Most stuff can run off 'Modified SW'. You can also buy a 2nd hand computer graded UPS. They are cheap and it is 'Pure SW'. I bought a 2nd hand 600W one for $2. The battery is small inside UPS but you can always hook it up to the car battery. The only thing is some higher output ones use 2 x 12V ( 24V ) battery. Good luck with your search.
