•
DC over-current protection is not included with the Rosie and must be provided as part of
the inverter installation.
Use a 300A DC breaker.
AC Wiring
•
When wiring the AC input and output circuits, we recommend a full system Inverter Bypass
Switch, which provides a convenient means to isolate the inverter for battery maintenance
and to continuously power AC loads without any re-wiring.
•
The wire sizes recommended in this manual are based on the ampacities given in Table
310.17 (in free air) of the NEC, ANSI/NFPA 70, for 90ºC copper wire based on an ambient
temperature of 30ºC (86ºF).
•
Always use properly rated circuit breakers. If using an electrical sub-panel, circuit breakers
can be moved from the main electrical panel to the sub-panel only if the breakers are also
listed to be installed in the sub-panel.
•
The AC wiring must be protected from short circuits and overloads by an over-current
protection device (UL1077 standards) and have a means to disconnect the AC circuits.
•
An AC generator wired into the Rosie must have an emergency shutdown device located
outside the dwelling at a readily accessible location (NEC 445.18).
•
DO NOT connect the inverter’s output to an external AC power source. This could cause
severe damage to the inverter and is not covered under warranty.
•
AC loads powered by the inverter will need to be installed into an electrical sub-panel with
branch breakers to power the AC loads.
•
The AC IN and OUT neutrals are common and may be wired to a common neutral bus.
Mobile Installations
(MNROSIE7048M)
•
The AC IN and OUT neutrals must be isolated from each other. Do not route the AC IN and
OUT neutrals to a common neutral bus. See page 15 for important information on Mobile
Installations.
•
Use #6 AWG (or larger), 600V wire for the AC IN and AC OUT wires.
