Utility AC voltage

The LG Electronics ESS inverters are grid-tied to the public utility. The inverters are software 

configurable via the user display panel for various 208 V AC or 240 V AC 60 Hz public utility grids.

CAUTION

The LG Electronics ESS Inverters should never be connected to a 120 V AC utility service. NEC 
705.12 requires that the inverter be connected to a dedicated circuit with no other outlets or 
devices connected to the same circuit.

AC connection voltage and frequency limits:

Voltage range for 208 V nominal, line to line

185 V - 226 V

Voltage range for 240 V nominal, line to line

213 V - 262 V

Frequency Range

59.3 Hz - 60.5 Hz

Public grid configuration allowed:

< 240 V / 120 V Split Phase AC Grid >

< 208 V Inverter AC Grid >
