Grid outage switchover takes several seconds, not instant
reported in the field
Symptoms
- During a real power outage on a three-phase Australian installation, roughly a two-second gap occurred before the battery took over -- long enough to reset a computer and router -- rather than a seamless sub-second switchover
- The gap coincided with the battery's state of charge being low at the time
- Two other owners separately reported similar multi-second delays
