Page 7: How To Kill Your Batteries
MNE300ROSIE-240P MANUAL STANDARDS The MidNite Solar MNE300ROSIE-240P conforms to UL 1741, Safety for Inverters, Converters, Controllers and Interconnection System Equipment for Use with Distributed Energy Resources, UL 1741:2010 Ed.2+R:15Feb2018; CSA C22.2#107.1:2016 Ed.4; and UL 458:2015Ed.6 Power Converters/Inverters and Power Converter/Inverter Systems for Land Vehicles and Marine Crafts. -
Page 8: How An Inverter/Charger Works
MNE300ROSIE-240P MANUAL • Not verifying you are charging to the voltage supplied by the battery manufacturer. • Not fully charging your lead acid batteries at least once a week. • Failing to keep all connections clean. 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: Dc Wiring And Over-Current Protection
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: Ac Wiring And Over-Current Protection
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.
