Starting at $2,699, the Oupes Guardian 6000 V2 aims to prove you don't need to spend enterprise-grade money to get true whole-home backup power. These include AC charging, solar charging, and ports for connecting G5 expansion batteries. Power Output and Performance: True 240V Split-Phase Power for Whole-Home BackupMost portable power stations operate in the 2,000 to 3,000W range. The Guardian 6000 V2 doesn't offer the depth of a full home energy ecosystem, but it provides more control than I expected. Oupes has since corrected this with the Guardian 6000 V2, adding support for over-the-air firmware updates through the mobile app.
