Utility AC voltage
The Solectria PVI Inverters should never be connected to a
120 Vac utility service. NEC 690.64(b)(1) requires that the inverter
be connected to a dedicated circuit with no other outlets or devices
connected to the same circuit.
CAUTION!
PRUDENCE!
Grid configurations allowed:

The Solectria PVI inverters are grid-tied to the public utility. PVI inverters are software configurable
via the user display panel for various 208 Vac or 240 Vac 60 Hz service configurations as shown
in figures 18-22.
