2.0 Introduction 2.0 Introduction Congratulations on your purchase of the Mini Magnum Panel (MMP) enclosure, part of a new line of Panel Systems from Magnum Energy. Installing an inverter system is now as simple as mounting the MMP enclosure, installing the inverter, connecting the battery bank, and if needed, bringing in AC power from a generator or the utility. The inverter’s required AC and DC disconnects and wire connection points are all together, and integrated in one self-contained MMP enclosure.
2.0 Introduction 2.1 MMP Series Overview The MMP enclosures are available in four basic configurations; this section lists the four models and the main components and features.
2.0 Introduction 2.2 MMP External Components As shown in Figure 2-1, the main components found on the outside of the MMP enclosure are: 1 Top Plate - The MMP enclosure is shipped with the top plate installed and is used either as an upper conduit plate or a safety plate. If you are not installing a Magnum inverter, then use this plate to route the AC and DC wiring from the MMP enclosure to the inverter.
2.0 Introduction 2.3 MMP Internal Components The following components are found inside the MMP enclosure (refer to Figures 2-2 thru 2-5): 1 DC Negative to Ground Connection - A busbar connects the DC negative to the system ground. This busbar can be removed if the primary DC negative to ground connection is made elsewhere in the system (see Section 3.12). 2 Mounting Dimples (x4) - These dimples allow the optional ME-BMK-NS (Battery Monitor Kit without DC shunt) to be installed.
2.0 Introduction 13 DC Ground Stud - This 5/16” stud is connected to the MMP enclosure chassis and is provided as a connection point to the DC grounding electrode when the conductor is larger than #1/0 AWG. This 5/16” stud also connects to the DC Shunt through a busbar and serves as the DC negative to ground connection point. If installing a PV-GFP device, this busbar must be removed (see Section 3.12). Note: For ground wires #1/0 AWG or smaller, use the DC Ground Busbar (Item 20).

3.0 Installation 3.8.3 Inverter DC Overcurrent Protection and DC Disconnect In a battery based inverter system, the NEC/CEC assumes that each ungrounded conductor is connected to some source that supplies currents in excess of the ampacity rating of the conductor and could potentially damage that conductor under fault conditions.
3.0 Installation 3.8.5 DC Hardware Connections Do not put anything between the DC cable lug and the DC terminals (i.e., on the DC circuit breaker, DC shunt, batteries, and inverter/busbars). Ensure the hardware used to hold these connections is stacked correctly. Incorrectly installed hardware causes a high resistance connection which could lead to poor inverter performance, and may melt the cable and terminal connections.

3.0 Installation 3.8.6 Wiring the Battery Bank Depending upon the voltage of the batteries you use in the installation (6 or 12 VDC), the batteries must be wired in series, parallel, or series-parallel to provide the correct voltage. The interconnecting DC wires should be sized and rated exactly the same as those that are used between the battery bank and the inverter. Place the batteries as close as practical to the MMP enclosure/inverter system, preferably in an insulated and ventilated enclosure.
3.0 Installation 3.9 AC Wiring This section provides information on the AC wiring inside the MMP enclosure to/from the inverter, from the incoming AC source and to the outgoing AC distribution panel (i.e., inverter sub-panel). 3.9.

3.0 Installation 3.9.3 AC Wire Size and Overcurrent Protection The AC input and output wiring must be sized per the local electrical safety code requirements to ensure the wires ability to safely handle the inverter’s maximum load current. After determining the proper AC wire sizes, they are required to be protected from short circuits and overloads by an overcurrent protection device, and have a means to disconnect the AC circuits.
3.0 Installation 3.9.5 AC Wiring Configurations The following table provides the different wiring configurations for installing and connecting the AC conductors into and out of the inverter (refer to Figures 3-14 to 3-17 for installation drawings showing these configurations).

3.0 Installation 3.10 MMP/Inverter System Grounding The MMP/inverter system uses both AC and DC electrical systems, therefore each electrical system is required to be properly connected to a permanent, common “ground” or “earth” reference. A MMP/inverter system that is properly grounded limits the risk of electrical shock, reduces radio frequency noise, and minimizes excessive surge voltages induced by lightning.
3.0 Installation 3.10.1 Sizing the Grounding Electrode Conductors AC Side - The size of the AC Grounding Electrode Conductor (GEC –AC) depends on the size of the largest ungrounded conductor feeding the AC load center. One #8 AWG (8.4 mm2) copper conductor will serve as an AC Grounding Electrode Conductor (GEC –AC) for AC power conductors smaller than and including #2 AWG (33.6 mm2) copper. See Table 3-6 for additional values.
3.0 Installation 2. Multiple Connections to Ground - Single Electrode (Method 2): When the AC and DC service panels are near each other, then the AC Grounding Electrode Conductor (GEC – AC) and DC Grounding Electrode Conductor (GEC – DC) can be connected to a single Grounding Electrode (see Figure 3-20).
3.0 Installation 3.10.2 Equipment Grounding Conductor The MMP enclosure and all other non-current-carrying exposed metal surfaces in the entire electrical system that may be accidentally energized must be grounded. The equipment-grounding conductor must be sized to safely carry the maximum ground-fault current likely to be imposed on it from where a ground-fault may occur.
3.0 Installation 3.11 Removing the AC Neutral to Ground Connection In installations where the MMP enclosure is powered from utility power or large permanently installed generator systems, the AC neutral to ground connection is normally provided inside the main AC electrical distribution panel. In these systems, the factory-installed neutral to ground connection in the MMP enclosure must be removed to prevent multiple neutral-to-ground bonds.
3.0 Installation 3.13 Wiring Accessories The NEC/CEC requires the insulation of all conductors inside the MMP enclosure to be rated for the highest voltage present. The MMP enclosure is designed to work with 120/240VAC inverters, therefore, the voltage rating of the communications cables inside the MMP enclosure must be rated for 300 volts or higher to be code compliant. With the purchase of the MMP enclosure, Magnum has included three six-foot, yellow communication cables with 300-volt rated insulation.

3.0 Installation 3.14 Installation Checklist Use this checklist as a final review to ensure all essential steps to install the MMP enclosure have been made before proceeding with the functional test. Mounting The MMP enclosure/inverter system is securely mounted in a clean, dry, and ventilated area. The MMP enclosure/inverter system is not mounted in the same enclosure as maintenance-free or vented type vented batteries. The MMP enclosure is mounted in a vertical only position.
3.0 Installation Conductors and General Wiring Methods Conductors are rated for the application and the environment. Standard building-wire conductors and appropriate wiring methods are used. Note: Welding cables, marine, locomotive (DLO), and auto battery cables don’t meet NEC /CEC requirements. Flexible RHW or THW cables are available, but these cables require very limited, specially listed terminals.
3.0 Installation 3.15 Functional Test After all electrical connections from the MMP enclosure to the inverter, batteries, AC source, and sub-panel have been completed; follow these steps and refer to Figure 3-28 to test the installation of the MMP enclosure and verify proper operation of the BYPASS switch breakers.
3.0 Installation 7. Turn ON the INV OUT2 and INV IN breaker(s) in the MMP enclosure. a. Ensure the AC source power is passing thru the INV IN (Inverter Input) breaker by verifying the AC source voltage present earlier (in step 6) is also present on the AC Output Terminals. 8. After all the AC voltage checks pass, install the front cover and manually open and close all circuit breakers, checking for correct alignment and free operation. If all the steps pass, the MMP enclosure is ready for use.
4.0 Operation 4.0 Operation The MMP enclosure provides you with circuit breakers/disconnects to easily operate and maintain your inverter/battery system.
