Is an inverter sufficient to protect sensitive electronics like high end stereo equipment, or do I need a UPS? I’m building a house in an area that has frequent brownouts and power sags, and I know that’s not good for computers, TVs and stereo equipment. I’m guessing it’s not good for other electronics either, so I’m looking for a larger solution than a point UPS. Critical and sensitive systems are on a separate electrical panel with an eye toward a generator at some point in the future, but I still need to bridge the gap between when power drops and the genset kicks on (or simply bridge the power drop when it happens if it’s just a few seconds). Some power invertors tout very fast engagement times between power interruption and the inverter kicking in, 6 - 16 milliseconds. That’s not even enough time to cause digital clocks to reset, but is it sufficient to protect stereo electronics? I’d love to set it up to get pure sine wave power to the equipment, but whole house UPS is a five figure investment so that’s not an option for me. I’ve asked around found that electricians don’t know stereo equipment and stereo specialists don’t know whole house power systems. I’m looking for the 80/20 rule case here. A power inverter is 20% of the cost of a big UPS. For protecting sensitive electronics, does it provide 80% of the benefits?
