Safety Precautions

• All electrical work must be performed in accordance with local and national electrical codes.

• This product is designed for indoor/compartment installation. It must not be exposed to rain, snow, moisture, or liquids of any type.

• Use insulated tools to reduce the chance of electrical shock or accidental short circuits.

• There are no user-serviceable parts contained in this product.

• This unit is provided with integral protection against overloads.

• Live power may be present at more than one point since an inverter utilizes both DC (batteries, PV, etc.,) 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. Turning off the inverter will not reduce this risk, the inverter must be totally disconnected from all sources.

• Use Class 1 wiring methods for ﬁeld wiring connections to terminals of a Class 2 circuit.

• Listed or labeled equipment shall be installed and used in accordance with any instructions included in the listing or labeling.

• Always verify proper wiring prior to starting the inverter.

• Use only copper wires with a minimum temperature rating of 90°C.

• AC wiring must be no less than 10 AWG (5.3 mm²) gauge copper wire.

• Battery cables should be no less than #4/0 AWG for 12 and 24-volt systems and #2/0 AWG gauge for 48-volt systems. Crimped and sealed copper ring terminal lugs with a 5/16 hole should be used to connect to the DC terminals on the inverter.

• Torque all AC wiring connections and DC cable connections to the required torque values.

• Overcurrent protection of the battery cables must be provided as part of the system installation.

• Overcurrent protection of the AC output wiring must be provided as part of the system installation.

Safety Information

• The AC output neutral conductor and the DC negative conductors are not connected (bonded) to the inverter chassis. Both the input and output conductors are isolated from the enclosure and each other. System grounding, if required, is the responsibility of the system installer and must comply with local and national electrical codes and standards. Refer to the Section 2.10

“MMP/Inverter System Grounding” for more information.

Battery Safety

• Use insulated tools and be very careful when working around batteries, they can produce extremely high currents if short-circuited (e.g., dropping a metal tool across the battery terminal), which could cause a ﬁ re or explosion.

• Read and follow the battery manufacturer’s safety precautions before installing the inverter and batteries. Always verify proper polarity and voltage before connecting the batteries to the inverter. Once the batteries are connected to the inverter, ensure the maintenance and charging requirements (i.e., charge voltage and charge rate) provided by the battery manufacturer are followed to extend the life of the batteries and to prevent damage to the batteries while charging.

• Wear eye protection such as safety glasses, and avoid touching your eyes and face when working with batteries to keep any ﬂ uid/corrosion on the battery from coming in contact with eyes and skin. Have plenty of fresh water and soap nearby and thoroughly wash in case battery acid contacts skin, clothing, or eyes. In the event of exposure to the eyes, ﬂ ood 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; depending on your battery type, keep a supply on hand near the batteries.

• Remove all jewelry such as rings, watches, bracelets, etc., when installing or performing maintenance on the batteries and inverter. A battery can produce a short-circuit current high enough to weld metal jewelry, causing severe burns.

• Never work alone. Always have someone within the range of your voice or close enough to come to your aid when working around batteries.

• Use proper lifting techniques when working with batteries.

• Never use old or untested batteries. Check each battery’s label for age, type, and date code to ensure all batteries are identical.

• Batteries are sensitive to changes in temperature. Always install batteries in a stable environment.

• Batteries can produce explosive gasses, so install batteries in a well-ventilated area. For compartment or enclosure installations, always vent batteries from the highest point to the outside. Design the battery enclosure to prevent accumulation and concentration of hydrogen gas in “pockets” at the top of the compartment.

• Provide at least one inch of air space between batteries to provide optimum cooling.

• Never smoke or allow a spark near batteries.

• To prevent a spark at the battery and reduce the chance of explosion, always connect the cables to the batteries ﬁ rst. Then connect the cables to the inverter.

• Never charge a frozen battery.

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 2.11).

Ground Busbar – This busbar is connected to the MMP enclosure chassis and is used to tie AC and DC equipment grounds to a common point.

This busbar has dual hole sizes—three #14 to #1/0 AWG and six #14 to #6 AWG—with screw type compression terminals (no ring lugs required).

Inverter’s DC Negative Connection Busbar – Inverter’s DC negative terminal connects to the top of this busbar.

Inverter’s DC Positive Connection Busbar – Inverter’s DC positive terminal connects to the top of this busbar.

DC Shunt – A 500-amp/50 mV 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 A3 in Appendix A for information on installing and wiring the ME-BMK-NS battery monitor inside the MMP enclosure.

Battery Negative Connection – The bottom of the DC shunt is the connection point to the negative terminal of the battery bank.

Introduction

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 2.12).

Note: For ground wires #1/0 AWG or smaller, use the DC negative busbar (Item 20). DIN Rail Track – For installing up to eight 1/2” (12.7mm) wide, DIN rail-mounted,

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

Mounting Holes (x8) – For installing up to four 1” (25.4mm) wide, back-mounted, E-Frame type breakers. These breakers can be used for connecting DC loads or installing a PV-GFP device.

Inverter DC Disconnect Breaker – This disconnect is a heavy-duty high amperage circuit breaker speciﬁ cally designed for the MMP enclosures. 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 used in accordance with the installation instructions in this manual. The amperage rating depends on the MMP model (175 or 250 amps).

Battery Positive Connection – The bottom of the inverter’s DC disconnect is the connection point to the positive terminal of the battery bank. The DC disconnect has a front connected terminal with 3/8-16 captive nuts.

Battery 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 or connecting to DC load breakers.

This busbar is rated to handle 120 amps, and has dual hole sizes—two # 14 to #1/0 AWG and ﬁ ve #14 to #6 AWG—with screw type compression terminals (no ring lugs required).

PV Positive Busbar – This busbar provides a convenient connection point inside the MMP for the positive output from a PV array and the positive input to the PV charge controller.

This busbar is rated to handle 120 amps, and has dual hole sizes—two # 14 to #1/0 AWG and ﬁ ve #14 to #6 AWG—with screw type compression terminals (no ring lugs required).

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 common point for connecting additional DC circuits, such as from the DC negative output of a charge controller or combining the negatives of DC load circuit breakers.

This busbar is rated to handle 120 amps, and has dual hole sizes—two # 14 to #1/0 AWG and ﬁ ve #14 to #6 AWG—with screw type compression terminals (no ring lugs required).

Installation

2.2 Location

Refer to the dimensional drawing in Figure 2-2 to determine an appropriate area to install the MMP enclosure/inverter system. Install it only in a location that meets the following requirements:

Clean and Dry – The MMP/inverter system must be mounted indoors in a relatively cool, clean, and dry environment.

Ventilation – If a Magnum inverter is installed on the MMP 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 MMP enclosure ventilation openings or install it in an area with limited airﬂ ow. At the minimum, allow three inches of clearance to the left and right sides of the MMP enclosure to provide adequate ventilation.

Close to the Battery Bank – The MMP enclosure/inverter system should be located as close to the batteries as possible. This is to ensure the battery cable length is kept as short as possible. Long DC wires tend to lose efﬁ ciency and reduce the overall performance of an inverter. However, the MMP 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.

Info: Consult your inverter owner’s manual to determine the proper sized inverterto-battery cables for the distance that is used. However, this cable must not be sized any smaller than the minimum size requirement for the DC disconnect breaker in the MMP enclosure. The MMP175 models require a minimum 00 (2/0) AWG cable, and the MMP250 models require a minimum 0000 (4/0) AWG 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 twelve feet away from the MMP/inverter system. Do not install the MMP/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 MMP enclosure. Maintain at least a 36” (91 cm) clear space in front to access the AC and DC wiring terminals and connections inside the MMP enclosure, as they will need to be checked and tightened periodically.

2.3 Conduit Knockouts

The MMP enclosure comes standard with knockouts for 1/2”, 3/4”, 1”, 1¼”, 1½”, and 2” conduits.

Figure 2-2 shows the location of these conduit knockouts. The 1/2”, 3/4”, and 1” knockouts are for the PV array, DC loads, and other smaller input cables. Select the appropriate knockout that is close to the terminal that the wire will connect to, or whichever one works for the way your ﬁ eld wiring comes in. The 1½” and 2” knockouts on the bottom of the MMP enclosure are used to connect to the battery bank.

Info: The knockouts can be easily removed by tapping the edge with a straight bladed screwdriver and a hammer, then twist out with pliers. Refer to Figure 2-3.

Before removing the appropriate knockouts and mounting the MMP enclosure, think about whether you are going to use

• Wiring from the MMP enclosure to an AC sub-panel

• Wire runs from the utility and/or a generator to the MMP enclosure

• Battery cable wiring from the battery bank to the MMP enclosure

• Additional wiring from any external DC source (PV, wind, or hydro) to the MMP enclosure

• Small signal wiring (battery sensors, battery monitoring, auto gen starting)

• Attaching lightning arrestors

• PV charge controller wiring

cable clamps or conduit and all the different wiring required, such as:

2.4 Mounting

To meet regulatory requirements, the MMP enclosure must be mounted on a vertical surface (on a wall) in an upright position, as shown in Figure 2-4. The DC breaker will not operate properly unless in the vertical position.

Note the height you want to locate the MMP enclosure, and ensure you can access any controls and wiring terminals. Refer to the physical dimensions as shown in Figure 2-2, or use the base of the MMP as a template to mark your mounting screw locations. After marking the mounting screw locations, ﬁ rmly secure the MMP/inverter to the solid vertical surface using appropriate mounting hardware.

This surface and the mounting hardware must also be capable of supporting at least three times the combined weight of all the components (i.e., MMP enclosure, inverter, and any other accessory mounted). When considering the strength of the support surface, remember the MMP enclosure weighs 22.5 lbs. (10.2 kg), and the Magnum inverter can weigh up to 60 lbs. (27.2 kg).

If installing a Magnum inverter on the MMP enclosure, the inverter base can reach a temperature up to 194°F (90°C); it is recommended that it should be mounted on a non-combustible surface*.

To meet regulatory requirements with a Magnum inverter mounted vertically, the included inverter hood (PN: MP-HOOD) must be installed on the top to prevent the risk of ﬁ re from objects falling into the inverter. See Figure A5-1 in Appendix A for more information on the inverter hood.

Info: Magnum provides a steel backplate (PN: BP-MMP) that has a suitable surface and the required support for mounting the MMP enclosure and Magnum inverter together. For information and dimensions on this backplate, see Figure A8-1 in Appendix A.

Info: If mounting the MMP enclosure to wood (without a Magnum inverter), use at least a #10 gauge sheet metal or wood screw. For concrete or hollow walls use a minimum 1/4 inch bolt and anchor.

* Non-combustible surface – A surface made of material that will not ignite, burn, support combustion, or release ﬂ ammable vapors when subjected to ﬁ re or heat as per the ASTM E136 standard. For the most part, these are materials that are largely comprised of inorganic materials such as stone, steel, iron, brick, tile concrete, slate, and glass. Common building materials such as gypsum board as well as any paint, wall coverings, and certainly wood will not pass.
