2.0 Introduction

The Magnum P dardize inverter installations and allow for the ability to expand the inverter system in the future.

Speciﬁ cally designed for multiple inverter applications, the MP enclosures ensure safety and reliability by combining all of the major components required for a renewable energy system — inverter/ battery disconnect, AC overcurrent protection, grounding connections, and a full-system bypass switch — into an easy to install pre-wired enclosure. The modular design of the MP enclosure with the Magnum Energy inverter allows it to be UPS shipped and easily assembled on site.

Installing an inverter system is now as simple as mounting the MP enclosure, installing the inverters, connecting the battery bank, and if needed, bringing in AC power from a generator or the utility grid. Now all of the inverter’s required AC and DC disconnects and wire connection points are all together, and integrated in the self-contained MP enclosure.

anels (MP) are part of a new line of enclosures from Magnum Energy that stan-

used to connect the incoming and outgoing AC circuit grounds to a common ground point.

AC LEG 1 IN Busbar - Connects incoming LEG 1 AC power from the grid or a generator to the MP/inverter system. This busbar is used to connect the LEG 1 output of a 120/240V AC external source (grid power or AC generator) to the MP enclosure. The AC LEG 1 IN busbar is connected to the HOT 1 input of the inverter system (thru the inverter’s AC input breaker). The external source is used by the inverter to charge the batteries and power downstream loads thru the inverter.

AC LEG 1 OUT Busbar - Supplies the LEG 1 power from the MP/inverter system to the AC loads. This busbar is the connection point from the MP enclosure to the LEG 1 terminal in the electrical panel powered by the inverter.

AC LEG 2 IN Busbar - Connects incoming LEG 2 AC power from the grid or a generator to the MP/inverter system. This busbar is used to connect the LEG 2 output of a 120/240V AC external source (AC generator or grid power) to the MP enclosure. The AC LEG 2 IN busbar is connected to the HOT 2 input of the inverter system (thru the inverter’s AC input breaker). This external source is used by the inverter to charge the batteries and power downstream loads thru the inverter.

AC LEG 2 OUT Busbar - Supplies the LEG 2 power from the MP/inverter system to the AC loads. This busbar is the connection point from the MP enclosure to the LEG 2 terminal in the electrical panel powered by the inverter.

AC NEUTRAL Busbars - The neutral leg for loads powered from the MP/inverter system and the neutral leg for AC power supplied to the MP/inverter system by either a generator or grid. These two busbars are the connection points for the AC neutrals in the system. The system neutrals include: the neutral output from the external AC source (generator/grid), the neutral terminal in the electrical panel that is powered by the inverter, and the input and output neutral terminals of each inverter. Note: Both AC NEUTRAL busbars are electrically connected to each other.

All the busbars have dual hole sizes — the larger holes accept #14 to #1/0

and the smaller holes accept #14 to #6 AWG — these holes have set-screw type

All AC Ground Busbars, DC Ground Busbars, and the DC Ground Stud are electrically

Busbar(s) - These busbars are connected to the MP enclosure chassis and are

• Installing MS-PAE Series inverters: Both neutral terminals are common with each other within the MS-PAE Series, this means only one neutral from each MS-PAE inverter needs to connect to the AC NEUTRAL busbar.

• Installing MS4024 inverters: The Neutral In and Neutral Out are not common with each

other within the MS4024; this means both input and output neutrals from each MS4024 inverter needs to connect to the AC NEUTRAL busbar.

AC NEUTRAL-GROUND Connection - A wire (green) connects the AC neutral to the system ground. This green wire can be removed from the GROUND busbar if the primary AC neutral to ground connection is made elsewhere in the system (see Section 3.10).

Battery Negative Connection - The bottom of the DC Shunt busbar is the connection point to the negative terminal of the battery bank. This busbar is supplied with a 3/8-16 bolt and lock washer to allow the battery cable to be connected.

2.0 Introduction

Battery

point to the positive terminal of the battery bank. The DC disconnect provides a rear captive nut to allow the battery cable to be front-connected using a 3/8-16 bolt and lock washer.

DC GROUND Busbar - This busbar is connected to the MP enclosure chassis and is used to tie DC equipment grounds to a common point. This terminal is also used to connect the inverter/ MP/inverter system to the DC grounding electrode. If the DC grounding electrode conductor is greater than #1/0 AWG, use the DC Ground Stud to connect to the DC grounding electrode (i.e., ground rod).

DC Ground Stud - This 5/16-18 stud is connected to the MP enclosure chassis, and is provided as a connection point to the DC grounding electrode when the conductor is larger than #1/0 AWG.

This 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 3.11). Note: For ground wires #1/0 AWG or smaller, use the DC GROUND busbar.

DC NEGATIVE Busbar - This busbar is connected to the battery bank negative through the load side of the DC shunt. This busbar is the battery negative connection point for additional DC circuits, such as from the DC negative output of a charge controller or when combining the negatives of DC load circuit breakers. This busbar is rated to handle 120 amps.

DC NEGATIVE-GROUND Connection - This busbar connects the DC negative to the system ground. It must be removed if the primary DC negative to ground connection is made elsewhere in the system (see Section 3.11).

DC POSITIVE Busbar - This busbar is connected to the battery bank positive through the bottom of the inverter DC disconnect. This busbar is the battery positive common point for connecting additional DC circuits, such as from the output of a charge controller disconnect, the DC positive feed to DC load breakers, and the positive connection to a battery status monitor. This busbar is rated to handle 120 amps.

DC Shunt - A DC shunt installed in the DC negative side that is used to measure the amperage ﬂ owing between the battery and the inverter (and any DC loads connected). This shunt is

pre-installed so that a battery monitor may be easily connected to display the current ﬂ ow. See Section A-2 for information on installing and wiring the ME-BMK-NS battery monitor inside the MP enclosure. The MPSL-30D and MPSL-60S are supplied with a 500 amp/50mV DC shunt, and the MPSH-30D and MPDH-30D have a 1000A/100mV DC shunt.

DC Shunt Voltage Sense Terminals - These two shunt terminals/screws serve as the sense connections to the optional ME-BMK-NS battery monitor. When current is passed through the shunt, the IR drop (AKA voltage drop) developed across it can be read by the battery monitor to provide an accurate indication of the current ﬂ owing through the shunt.

DIN Rail Track - For installing up to 1/2” (12.7mm) wide, DIN rail-mounted, Q-Frame type, DC breakers. These breakers can be used for connecting DC loads or installing a PV-GFP device. The track may be removed to allow 1” (25.4mm) wide, back-mounted, E-Frame type breakers to be installed instead.

Enclosure Joining Screw/Washer - A #10-32 x 3/8” (Pan head, T25 Torx drive) thread cutting screw and #10 lock washers are provided to join the two enclosures of the MPDH-30D together – to have them at the same electrical potential. See Figure 3-16c for more information.

INV HOT 1 OUT Busbar - This busbar is the connection point for the HOT 1 output from each installed inverter. The total output power combined from every inverter on this busbar is fed thru the Inverter Bypass Breaker Assembly to the AC LEG 1 OUT Busbar.

INV HOT 2 OUT Busbar - This busbar is the connection point for the HOT 2 output from each installed inverter. The total output power combined from every inverter on this busbar is fed thru the Inverter Bypass Breaker Assembly to the AC LEG 2 OUT Busbar.

Positive Connection - The bottom of the inverter’s DC disconnect is the connection

circuit, a way to disconnect the AC input to the inverters, and overcurrent protection to the inverter’s input wires when the minimum recommended AC wire sizes are used. Depending on

your MP model, the breaker provided for the inverter input will be either a double-pole 30 amp (D30A) or a single-pole 60 amp (S60A) AC breaker.

The double-pole 30 amp AC breaker is provided on the MPSL-30D, MPSH-30D, and MPDH-30D models to allow 120/240V AC inverters — up to 30 AC amps per leg pass-thru capability — to be

connected. The MPSL-30D and MPSH-30D come with one double-pole 30A input breaker and the MPDH-30D comes with two double-pole 30A breakers. These three models require a double-pole 30A breaker for each additional inverter installed in a parallel-stacked conﬁ guration.

The single 60 amp AC breaker is provided on the MPSL-60S models to allow 120V AC inverters — up to 60 AC amps pass-thru capability — to be connected. If connecting MS4024’s in a series-stacked conﬁ guration, an additional single pole 60A breaker for the second MS4024 will be required (as provided in the MPX extension kit).

Inverter Bypass Breaker Assembly - The Inverter AC Bypass Breaker Assembly is pre-wired at the factory and consists of the inverter bypass switch and the inverter AC output disconnect breaker. This breaker assembly provides a way to disconnect the AC output of the inverter system, and to directly connect the AC input to the AC output by bypassing the inverter system.

The MPSL-30D and MPSL-60S are installed with a double-pole 60-amp AC bypass breaker assembly, and the MPSL-30D and MPDH-30D are equipped with a double-pole 125-amp AC bypass breaker assembly.

Inverter DC Disconnect Breaker - This 250 amp DC disconnect is a high interruption capacity, magnetic-hydraulic, DC circuit breaker. These breakers were speciﬁ cally designed and tested to work with Magnum inverters to provide the delay time needed to minimize nuisance breaker

tripping. It provides an easy and convenient way to isolate the inverter from the battery, and meets the NEC/CEC requirements for DC overcurrent protection when the size and length of the battery-to-inverter cables are installed in accordance with the installation instructions in this manual. These breakers have front-accessible connections, each provided with 3/8-16 Hex head

bolts with lock washers.

Inverter’s DC Negative Connection - Connects to Magnum inverter’s DC negative terminal.

Inverter’s DC Positive Connection - Connects to Magnum inverter’s DC positive terminal.

Mounting Dimples, BMK (x2) - These dimples allow the optional ME-BMK-NS (Battery Monitor

Kit without DC shunt) to be installed. Two #8-32 x 1/2” (T20 Torx drive) thread cutting screws are provided to mount the battery monitor. See Section A2 for more information on mounting the battery monitor.

Mounting Holes, Inv AC Input Breakers - Used to install additional Inverter AC Input Breakers, which provide protection to each inverter’s AC input circuit.

Mounting Holes, Inv DC Backmount Breakers - For installing 1” (25.4mm) wide, back-

mounted, E-Frame type, DC breakers. These breakers can be used for connecting DC loads or installing a PV-GFP device.

Mounting Holes, Inv DC Disconnect Breakers - Used to install additional Inverter DC Disconnect Breakers, which isolate the inverter from the battery. These breakers meet the NEC/

CEC requirements for DC overcurrent protection when used in accordance with the installation instructions in this manual.

Mounting Keyholes, MP Enclosure (x4) - Four keyholes for mounting the enclosure. See Figures 3-5 or 3-6 for size information on these keyholes.

Input Breakers - These breakers provide protection to the inverter’s AC input

3.0 Installation

3.2

Choosing an appropriate location for the MP/inverter system should be determined early in the installation process; install it only in a location that meets the following requirements:

Indoors ment away from sources of high temperature and moisture. The MP enclosure uses plated copper busbars, powder coated metal components, and plated fasteners, which means it is very tolerant to corrosive or condensing environments (one in which humidity and/or temperature change causes water to form on components). However, inverters are complex microprocessor controlled devices and should be treated as sophisticated electronic devices, such as computers or stereo equipment. When selecting the location for the MP/inverter system, don’t think of it in the same terms as the other connected equipment, e.g., batteries, generators, etc. When inverters are exposed to a corrosive or condensing environment their life will be shorten, and damage because of corrosion is not covered by the product warranty.

Ventilation - If a Magnum inverter is installed on the MP enclosure, the inverter will pull in air through the intake vents. In order for the inverter to provide full output power and avoid overtemperature fault conditions, do not cover or block the MP enclosure ventilation openings or install it in an area with limited airﬂ ow. At the minimum, allow 3 inches of clearance to the left and right

of the MP enclosure to provide adequate ventilation.

Close to the Battery Bank - The MP enclosure/inverter system should be located as close to the batteries as possible. This is to ensure the battery cable length is kept short. Long DC wires tend to lose efﬁ ciency and reduce the overall performance of an inverter. However, the MP enclosure, the inverter, and any other equipment that can spark (or that corrosion could damage) should not be installed in the same compartment/room as the batteries, or mounted where it will be exposed to gases produced by the batteries. These gases are corrosive and will damage this equipment; also, if these gases are not ventilated and if allowed to collect, they could ignite and cause an explosion. Consult your battery supplier for proper installation requirements.

Location

The MP/inv

erter system must be mounted indoors in a relatively clean and dry environ-

Info: Consult the inverter owner’s manual to determine the proper inverter-to-battery

ble size for the distance used. However, this cable must not be sized any smaller than

ca 0000 (4/0) AWG if the DC disconnect breaker in the MP enclosure will also be used as the overcurrent device. If a cable smaller than 4/0 AWG is used, an appropriately sized fuse must be installed to provide overcurrent protection to this smaller cable.

Safe - Keep any ﬂ ammable/combustible material (e.g., paper, cloth, plastic, etc.) that may be ignited by heat, sparks or ﬂ ames at a minimum distance of 12 feet away from the MP/inverter system. Do not install the MP/inverter system in any area that contains extremely ﬂ ammable liquids like gasoline or propane, or in locations that require ignition-protected devices. Sparks from relays, circuit breakers, etc., could ignite the fumes or spills.

Accessible - Do not block access to the front of the MP enclosure. Maintain at least a 36” (91 cm) clear space in front to access the AC and DC wiring terminals and connections inside the MP enclosure, as they will need to be checked and tightened periodically.

RFI - Most inverters can create RFI (Radio Frequency Interference). Keep this in mind when determining the placement of the MP/inverter system. You should locate the MP/inverter system as far away as possible from any electronic equipment susceptible to radio frequency and electromagnetic interference.

Expandability - The MP enclosure was speciﬁ cally designed to allow multiple inverters to be connected together. Keep in mind as your power needs grow, you can connect additional inverters (using MPX enclosures - up to your models maximum inverter capability) to increase your power capability. Use Figures 3-5 or 3-6 (depending on your MP model) to determine if you are allowing the appropriate vertical and horizontal room to expand your MP/inverter system.

Rodent Proof - Ensure the MP/inverter system is located in an area that prevents rodents and insects from entering and damaging wires/components – the MP/inverter can provide a warm habitat in a cold environment. Mesh screens or nets may need to be installed over any openings to ensure the unit is kept rodent free and well ventilated.

Notes:

1. Lengths shown in inches.

MPSL models

allow 1-2 inverters and MPSH models allow 1-3 inverters. Installations using one inverter do not require a MPX extension, two inverters require one MPX extension, and three inverters require two MPX extensions.

3. To meet UL regulatory requirements, an inverter hood must be installed above each Magnum inverter that is mounted on the Magnum Panel (vertically).
