HOW AN INVERTER/CHARGER WORKS Inverter Mode When the inverter is properly connected to batteries and turned on, the direct current (DC) from the batteries is transformed into a pure sine wave alternating current (AC).
  • Page 9 MNE300ROSIE-240P MANUAL o Coordination of conductor sizes and over-current protection shall be done in accordance with the Canadian Electrical Code, Part 1. • Use only copper wires with a minimum temperature rating of 90°C. • The equipment ground is marked with this symbol: CAUTION! The Rosie E-Panel is designed for indoor installation or installation inside a weatherproof enclosure.
  • Page 10 MNE300ROSIE-240P MANUAL • A readily accessible battery disconnect is required and must be located within sight of the battery system (NEC 480.7). o If the batteries are external to the location of the Rosie, then the battery installation must be done in accordance with the storage battery rules of the Canadian Electrical Code, Part 1.
  • Page 11 MNE300ROSIE-240P MANUAL WARNING! Do NOT connect the E-Panel’s AC OUT to an external AC power source. WARNING! In most electrical systems, the neutral-to-ground bond is located in the main utility service entrance panel. Remove any bond downstream from the inverter to prevent multiple bonds. If there is an inverter sub-panel—separate from a main electrical panel—it should have a removable wire that allows the neutral bus to be unbonded from the ground busbar.
  • Page 12 MNE300ROSIE-240P MANUAL • The AC neutral and equipment ground should only be bonded in one location for the entire system. Arc Fault - The NEC requires any PV system DC circuit operating at 80VDC or greater must be protected by an arc fault (AF) circuit interrupter. Ground Fault - Since 2008 the NEC requires a DC Ground Fault (GF) Protection device on all PV systems to indicate when a GF condition exists.
