Page 3 The bond must be made in the AC system (commonly at the AC service panel). MNROSIE7048M – a 7000-watt inverter/charger with 60-amp AC transfer relay and 120- amp, multi-stage PFC battery charger. The AC IN and OUT Neutrals are NOT common to allow automatic neutral-to-ground switching for Mobile applications (RV, truck, or marine).
Page 4 IMPORTANT SAFETY INSTRUCTIONS SAVE THESE INSTRUCTIONS THIS MANUAL CONTAINS IMPORTANT SAFETY INSTRUCTIONS FOR THE MIDNITE SOLAR ROSIE INVERTER/CHARGER THAT SHALL BE FOLLOWED DURING INSTALLATION AND OPERATION. If you do not fully understand any of the concepts, terminology, or hazards outlined in these instructions, please refer installation to a qualified dealer, electrician, or installer.
Page 5 MNROSIE7048 MANUAL SAFETY PRECAUTIONS • Live power may be present at more than one point since an inverter utilizes both DC (batteries) and AC (utility or generator) power. To reduce risk of electric shock, ensure all DC and AC wiring is disconnected prior to installing or performing maintenance on the inverter.
Page 6 MNROSIE7048 MANUAL o Rosie’s Class 2 circuits: CANBUS, Batt Temp Sensor; AUX terminals; WBJr terminal. • Use insulated tools to reduce the chance of electrical shock or accidental short circuits. • Turn off all breakers prior to removing front cover and working on the inside of Rosie. •...
Page 7 MNROSIE7048 MANUAL water and soap nearby and thoroughly wash in case battery acid contacts skin, clothing, or eyes. In the event of exposure to the eyes, flood them for at least 15 minutes with running water and seek immediate medical attention. Baking soda neutralizes lead acid battery electrolyte and vinegar neutralizes spilled NiCad and NiFe battery electrolyte;...
Page 8 Add distilled water as needed. Do NOT fill to the bottom of the funnel neck before you equalize. The electrolyte will probably spill out. o Use the MidNite Solar’s MNHYDROMETER to measure the specific gravity. Check with your battery manufacturer for the specific gravity values.
Page 9 MNROSIE7048 MANUAL • Not using ALL EQUAL LENGTH interconnect cables on each string. It is important that ALL strings be wired EXACTLY the same. Any variance in resistance on one string versus another will cause an imbalance and the batteries will suffer a shortened lifespan. •...
Page 10 MNROSIE7048 MANUAL INVERTER APPLICATIONS Permanent Installations • An inverter can be used for backup power in a permanent location that normally uses utility power, such as a home or office. When utility power is available, the inverter keeps the batteries charged. When the utility power fails, the inverter automatically supplies AC power to your home or office during the power failure.
Page 11 MNROSIE7048 MANUAL • Use only copper wires with a minimum temperature rating of 90°C. • The equipment ground is marked with this symbol: CAUTION! The Rosie is designed for indoor installation or installation inside a weatherproof enclosure. It must not be exposed to rain and should be installed out of direct sunlight. WARNING! Wait 5 minutes after deenergizing (breakers opened, fuses removed) all sources of DC power (batteries) and AC power (utility or AC generator) to the Rosie inverter before...
Page 12 MNROSIE7048 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 13 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.
Page 14 MNROSIE7048 MANUAL AC Ground Fault Circuit Interruption (GFCI) UL standards require the use of GFCI outlets or breakers on the AC output of an inverter WARNING! RISK OF ELECTRIC SHOCK! Use only ground-fault circuit interrupters [receptacle(s) or circuit breaker(s)] compatible with your inverter/charger. AC Over-Current Protection •...
Page 15 SPECIAL INSTRUCTIONS FOR MNROSIE7048M INSTALLATIONS Marine Grounding When installing the MNROSIE7048M on a marine craft, there are several considerations that must be followed when grounding to ensure a safe installation, to prevent galvanic corrosion, and to adhere to American Boat and Yacht Council (ABYC) standards.
Page 16 MNROSIE7048 MANUAL onboard grounding requirements while greatly reducing (if not eliminating) the risk of galvanic corrosion. These solutions would be either using a galvanic isolator or an onboard isolation transformer. Galvanic isolators allow high AC voltage faults to pass but block low voltage corrosion/electrolysis currents from conducting.
Page 17 AC source is actively powering the inverter loads. This can be prevented if your inverter is equipped with automatic neutral-to-ground switching, which the Rosie offers. • The MNROSIE7048M has Rosie Inverter Rosie Standby automatic neutral-to-...
Page 18 MNROSIE7048 MANUAL • When the MNROSIE7048M is connected to this external AC source and goes into Standby mode, the internal relay automatically opens the neutral-to-ground connection. This design keeps two neutral-to-ground connections from occurring at the same time, thereby preventing an electrical shock hazard between the vehicle/marine craft’s neutral and the external AC source’s neutral.
Page 19 MNROSIE7048 MANUAL • Ensure the Rosie is accessible after it is mounted. The Rosie is programmed and data points monitored via a remotely-mounted MNGP2 (MidNite Graphics Panel). You will need to access the MNGP2 during and after installation. • The Rosie should be protected from direct sun exposure or equipment that produces extreme heat.

Page 23 MNROSIE7048 MANUAL • There are two types of grounding: Equipment Grounding and System Grounding. o Equipment Grounding – Grounding for exposed metal parts, like the inverter chassis, solar panel frames, etc. See Figure 8. Reference Figure 8 o System Grounding – The bonding of a current-carrying wire below for grounding to earth ground, such as the two SBJs shown in Figure 8 or system terminology.
Page 24 MNROSIE7048 MANUAL o If you have two ground rods - AC goes to one and DC goes to the other - then you HAVE to bond those two ground rods together with a Bonding Conductor (BC). The NEC also dictates the proper size of that BC. •...
Page 25 MNROSIE7048 MANUAL Grounding in Marine Installations (MNROSIE7048M) • DC Equipment Grounding Conductor (EGC-DC) – must be equal in ampacity to the DC positive conductor, which is #4/0 AWG. In certain circumstances, the cable size may be one gauge smaller. Refer to the ABYC Standard for more information.
Page 26 MNROSIE7048 MANUAL shorted, the Rosie will default to a neutral temperature of 25C and will not temp-comp the charging voltages. In addition to temp-adjusting the charging voltages as mentioned above, the Rosie can be programmed to stop charging based on either a high or low battery temp setpoint. Connecting the BTS: 1.
Page 27 MNROSIE7048 MANUAL The shunt is wired in series on the electric low side, or negative side, of your system. The wire marked “Cable to Inverter Negative” (Figure 13) shows the shunt connection point for ALL negative wires from the Rosie, additional charge controllers, wind turbine negative, DC refrigerator, etc.

Page 43 MNROSIE7048 MANUAL BATTERY CHARGING Bulk This charging stage is called the Constant Current Mode, and it means the Rosie will send to the batteries as much current as is programmed (Max AC Charge Amps) until the battery voltage rises to the Absorb Voltage setpoint. Absorb The Rosie will maintain the Absorb voltage setpoint until the batteries are charged.
Page 44 MNROSIE7048 MANUAL Float The Float cycle follows the Absorb cycle. Think of Float as a trickle charger to keep the batteries full and topped off all day. The Rosie will hold the batteries at the Float voltage setpoint for the amount of programmed Float Time. Rebulk Forces the Rosie back into Bulk mode if the battery voltage is less than the REBULK setting for 60 seconds.
Page 45 MNROSIE7048 MANUAL 2. Reference temperature for the battery (Default is 25C). 3. The maximum voltage to ever compensate to. No temp comp or improperly programmed temp-comp may be harmful to your battery bank. In the winter, temp-comp will raise the charging voltage. This elevated voltage may cause an inverter to alarm on a high battery voltage condition.
Page 46 MNROSIE7048 MANUAL better with low-cost generators. The disadvantage is that Rosie can't catch the loads instantly if the grid disconnects. Silent acts like a "Smart Transfer" that only passes valid AC. • Standby means that the AC output bridge of the inverter is on and the inverter is in parallel with the grid.
