"The VSP Generator combines a complete energy management system with a battery management system all in one easy-to-use, turnkey, compact unit. This “one cart solution” is really five generators in one: The VSP Generator is an uninterrupted power source [UPS] to facilities that require a guaranteed source of clean, pure sine wave, uninterrupted power with built-in spike and surge protection. Or power a sump pump when the grid power fails....." - Scott Hunt from Practical Preppers.
