Introduction

1.0 Introduction

Congratulations on your purchase of a MS-PE Series inverter/charger from Magnum Energy. The MS-PE Series is a “pure” sine wave inverter designed especially for rugged mobile applications, home backup power, and standalone applications that require 230 VAC/50 Hz power. Powerful, yet simple to use, this inverter/charger will provide you with years of trouble-free performance you have come to expect from Magnum Energy.

When the power requirements of the system are beyond the capacity of a single MS-PE Series inverter or the system is expanded as more loads are added, up to four MS-PE Series inverters can be connected together in a parallel conﬁ guration. Connecting inverters in parallel increases the overall inverter power and surge capacity to power a large single load or several smaller loads.

Info: This is a sizeable manual and much of it is fairly technical. Terms may be used

throughout the manual that are unfamiliar to you. Refer to the Inverter/Charger Terminology glossary in Appendix D for clariﬁ cation.

The MS-PE Series inverter/charger includes the following:

• 4100 or 4300-watt models in a small footprint installation

• Ability to parallel up to four identical MS-PE inverters to increase output power capability

• Automatic Power Factor Corrected (PFC) multi-stage battery charging

• RS485 standard communication protocol

• Remote and Network ports (easy connection for optional accessories)

• Inverter-mounted ON/OFF switch with LED indicator

• 30-amp AC pass-thru capability

• DC terminal covers with 360 degree connection

• Field-serviceable for qualiﬁ ed personnel—tested repair kits available

• Automatic battery temperature compensation (using a battery temperature sensor)—for optimum charging even during extreme temperature changes

• Overcurrent, over-temperature, and high/low battery voltage protection

Info: Refer to the Optional Equipment and Accessories section in Appendix A-2 for a

list of accessories available for use with your MS-PE Series inverter/charger.

Also meets the C-Tick Mark requirement as attested by conformity with the standards for:

• AS/NZS CISPR 14-1:2005

Introduction

1.2 How an Inverter/Charger Works

There are two main modes of operation associated with the MS-PE inverter/charger:

• Inverter Mode:

When the inverter is properly connected to batteries and turned on, the direct current (DC) from the batteries is transformed into a pure sine wave alternating current (AC). This AC is similar to the voltage provided by your utility, and is used to power the electrical appliances (i.e., AC loads) connected to the inverter’s output.

• Standby Mode:

When an external source of AC power (e.g., utility power or generator) is connected and qualiﬁ ed on the inverter’s AC input, it operates in Standby mode. In Standby mode, the unit operates as a battery charger to convert the incoming AC power into DC power to recharge the batteries; while at the same time, automatically closing an internal AC transfer relay to pass the incoming AC power directly to the inverter’s output to continue powering the connected electrical appliances.

1.2.1 Inverter Applications for Permanent Installations

An inverter can be used for backup power in a permanent location that normally uses utility power, such as a home or ofﬁ ce. When utility power is available, the inverter keeps the batteries charged. When the utility power fails, the inverter comes on automatically to supply AC power to your home or ofﬁ ce during the power failure. For a home or business, reliable backup power is needed to prevent lost computer data, or to maintain lights and keep food fresh in the refrigerator/freezer.

In some areas, where utility power is not available, the inverter can be used in a standalone renewable power system. The inverter enables AC electrical appliances to be run from the storage battery bank. When the battery bank becomes discharged, either renewable DC sources (solar, wind, or hydropower) can be used to recharge the batteries, or a generator can be connected to the inverter to power the system while the batteries recharge.

1.2.2 Inverter Applications for Mobile Installations

Inverters can also be used to provide power in mobile applications (e.g., caravans or boats). In these applications, the inverter provides power to the AC loads using the energy stored in the batteries and recharges the batteries when shorepower or an onboard generator is available.

1.3 Advantages of using a Pure Sine Wave Inverter

Today’s inverters come in three basic output waveforms: square wave, modiﬁ ed sine wave (which is actually a modiﬁ ed square wave), and pure sine wave (see Figure C-1 in Appendix C). Modiﬁ ed sine wave inverters approximate a pure sine wave form and will run most appliances (see also Section C-1 “Appliance Power Consumption” in Appendix C) and electronics without any problems. These inverters are less expensive, and therefore, offer a viable alternative to more expensive pure sine inverters.

The output of the MS-PE Series, which is a pure sine wave inverter, is equal to or in many cases, better than the utility power used in your home. Virtually any electronic device will operate from a pure sine wave inverter. Motors run cooler, microwaves usually cook faster, and clocks keep better time just to name a few examples. Without compromising quality or performance, the MSPE Series provides you with all the advantages of a pure sine wave inverter at a much lower cost than many on the market.

The MS-PE Series is built on the same platform as our popular MS Series which helps reduce cost by using standard parts/accessories across many models. Magnum accessories such as the Advanced Remote Control (ME-ARC50), Standard Remote Control (ME-RC50), Automatic Generator Start-Networked (ME-AGS-N), and Battery Monitor Kit (ME-BMK) can be used. See Section A-3 “Optional Equipment and Accessories” for more information on these products.

Clean and Dry – The inverter should not be installed in an area that allows dust, fumes, insects,

or rodents to enter or block the inverter’s ventilation openings. This area also must be free from any risk of condensation, water, or any other liquid that can enter or fall on the inverter. The inverter uses stainless steel fasteners, plated copper busbars, a power-coated aluminum base, and the internal circuit boards are conformal coated—to help ﬁ ght the harmful effects of corrosive environments. However, the inverter’s life is uncertain if used in the above types of environments, and inverter failure due to any of the above conditions is not covered under warranty.

Info: If the inverter is installed in an area where moisture may occur, we recommend

putting silicone dielectric grease compound into the electrical ports (see Figure 1-1, Items 3-6). Before installing the cables, or if leaving any ports open, squirt a liberal amount into each port. Silicone dielectric compound makes an effective moisture and

corrosive barrier to help protect and prevent corrosion to the RJ11 connections.

Cool – The inverter should be protected from direct sun exposure or equipment that produces

extreme heat. The ambient temperature around the inverter must not exceed 25°C (77°F) to meet power speciﬁ cations.

Ventilation – In order for the inverter to provide full output power and to avoid over-temperature

fault conditions, do not cover or block the inverter’s ventilation openings or install this inverter in an area with limited airﬂ ow. The inverter uses two fans to provide forced air cooling, these fans pull in air through the intake vents (see Figure 1-2, Item 9) and blow out air through the exhaust vents (see Figure 1-3, Item 13). Allow at the minimum an airspace clearance of 15.2 cm (6”) at the intake and exhaust vents, and 7.6 cm (3”) everywhere else to provide adequate ventilation.

If installed in an enclosure, a fresh air intake opening must be provided directly to the inverter’s front side (intake vents) and an exhaust opening for the inverter’s back side (exhaust vents). This allows cool air from the outside to ﬂ ow into the inverter, and heated air to exit the inverter and the enclosure. When mounted in an enclosed compartment, airﬂ ow must be ≥100 cfm in order to maintain no more than a 20°C (68°F) rise in compartment temperature.

CAUTION: Do not mount this inverter in a zero clearance compartment, nor cover or

obstruct the ventilation openings—overheating may result.

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 61 cm (2 ft) away from the inverter.

Close to the battery bank – The inverter should be located as close to the batteries as possible.

Long DC wires tend to lose efﬁ ciency and reduce the overall performance of an inverter. However, the unit should NOT be installed in the same compartment as the batteries or mounted where it will be exposed to gases produced by the batteries. These gases are corrosive and will damage the inverter; also, if these gases are not ventilated and allowed to collect, they could ignite and cause an explosion.

Accessible – Do not block access to the inverter’s remote control and accessory ports, as well

as the inverter’s controls and status indicator. Allow enough room to access the AC and DC wiring terminals and connections, as they will need to be checked and tightened periodically. See Figure 2-3 for the MS-PE Series’ inverter/charger dimensions.

Away from sensitive electronic equipment – High-powered inverters can generate levels of RFI

(Radio Frequency Interference). Locate any electronic equipment susceptible to radio frequency and electromagnetic interference as far away from the inverter as possible.

2.2 Mounting the Inverter

The inverter base can reach a temperature up to 90°C (194°F) and should be mounted on a noncombustible surface*. This surface and the mounting hardware must also be capable of supporting at least twice the weight of the inverter. To meet regulatory requirements, the MS-PE Series must be mounted in one of the following positions (as shown in Figure 2-2):

• above or under a horizontal surface (shelf or table),

• on a vertical surface (wall) with the DC terminals to the right,

• on a vertical surface (wall) with the DC terminals toward the bottom, the MP-HOOD (inverter hood) installed on the top, and one of the following installed on the bottom: ME-CB or MPX-CB (conduit boxes), MS-CEFB (CE ﬁ lter box), MMP-E Series (single inverter enclosure), or MP-E Series (multiple inverter enclosure).

Info: The ME-CB, MPX-CB, MS-CEFB, MMP-E and MP-E enclosures all prevent material

from falling out the bottom in the event of an internal ﬁ re. The MP-HOOD inverter hood prevents items from falling inside, causing damage to the inverter.

Info: Magnum provides a backplate for mounting the inverter. These backplates also

provide the ability to mount either the MMP-E Series enclosure (PN: BP-MMP) or the MP-E Series enclosure (PN: BP-S single plate, or BP-D dual plate).

After determining the mounting position, refer to the physical dimensions as shown in Figure 2-3, or use the base of the inverter as a template to mark your mounting screw locations. After marking the mounting screw locations, mount the unit with appropriate mounting hardware.

* 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. Avoid common building materials such as gypsum board, painted surfaces, wall coverings, and any type of wood.

2.3 Wiring the Inverter – General Requirements

This section describes the requirements and recommendations for wiring the MS-PE Series inverter/ charger. Before wiring the MS-PE Series inverter/charger, read all instructions.

All wiring should meet all local codes and industry standards, and be performed by qualiﬁ ed personnel such as a licensed electrician.

Info: This document uses the term “ground”, or “grounding”; the European equivalent

is “earth”, or “earthing”. Refer to Appendix A-3 for equivalent AC/DC wiring terminology.

Inverter/charger systems involve power from multiple sources (e.g., inverter, generator, utility, batteries, solar arrays, etc.,) which makes the wiring more hazardous and challenging.

The input and output AC and DC circuits are isolated from the inverter chassis. The inverter system grounding is the responsibility of the installer in accordance with local codes and standard safety practices.

WARNING: Ensure all sources of DC power (e.g., batteries, solar, wind, or hydro)

and AC power (utility power or AC generator) are de-energized (i.e., breakers opened, fuses removed) before proceeding—to prevent accidental shock.

2.3.1 Protecting Wire – Conduit Box or Inverter Enclosure

The AC and DC wires into and out of the inverter must be protected as required by code. This can be done by using jacketed wires or by feeding the wires through conduit. To this end, Magnum offers DC conduit boxes (ME-CB or MPX-CB) and single (MMP-E Series) or multiple (MP-E Series) inverter enclosures. The enclosures include the necessary AC and DC inverter breakers that allow both the AC and DC conduit to be connected to the inverter.

Info: Remove the strain reliefs and replace with 3/4” grommets if using the ME-CB or

MPX-CB conduit boxes, MS-CEFB ﬁ lter box, or either Magnum enclosure system.

2.3.2 Wiring Requirements

• All conductors that are at risk for physical damage must be protected by conduit, tape, or placed in a raceway.

• Always check for existing electrical, plumbing, or other areas of potential damage prior to making cuts in structural surfaces or walls.

• Do not mix AC and DC wiring in the same conduit or panel unless speciﬁ cally approved/ designed for both AC and DC wiring. Where DC wiring must cross AC or vice-versa, try to make the wires at the crossing point perpendicular (90 degrees) to one another.

• Both AC and DC overcurrent protection must be provided as part of the installation.

• The inverter requires a reliable negative and ground return path directly to the battery.

• Use only copper wires with a minimum temperature rating of 75°C.

2.3.3 Wire Routing

Before connecting any wires, determine all wire routes to and from the inverter. Typical routing scenarios:

• AC input wiring from the main AC panel to the inverter

• AC input wiring from a generator (optional) to the inverter

• DC input wiring from the batteries to the inverter

• AC output wiring from the inverter to the AC sub-panel or to dedicated circuits

• Battery Temperature Sensor cable from the inverter to the batteries

• Remote control cable (optional) to the inverter

• Ground wiring to and from the inverter

2.3.4 Torque Requirements

• Torque all AC wiring connections to 1.8 N-m (16 in lbf). Torque DC cable connections from

13.6 to 16.3 N-m (10 to 12 ft lbf).

Installation

2.4 DC Wiring

This section describes the inverter’s required DC wire sizes, the recommended disconnect/ overcurrent protection, and how to make the DC connections to the inverter and the battery bank.

Refer to Figure 2-4 when connecting the DC wires.

WARNING: Even though DC voltage is “low voltage”, signiﬁ cant hazards may be

present, particularly from short circuits of the battery system.

CAUTION: The inverter is NOT reverse polarity protected—which means that if the

negative and positive battery voltage is connected backwards to the inverter, the inverter will likely be damaged. You should verify the correct voltage polarity using a voltmeter BEFORE connecting the DC wires.

CAUTION: Before wiring the DC cables, review the safety information at the beginning

of this manual and the instructions below to ensure a safe and long-lived system.

Info: DO NOT connect the battery cables to the inverter until all wiring is complete and

the correct DC voltage and polarity have been veriﬁ ed.

• When the inverter is installed in a photovoltaic system, standard safety practices require that the DC circuit conductors and overcurrent devices to the inverter be sized to carry not less than 125% of the inverter’s maximum current rating.

• The DC positive and negative cables connected to the inverter from the battery bank should be tied together with wire ties or electrical tape approximately every 15.2 cm (6”). This helps improve the surge capability and reduces the effects of inductance, which improves the inverter waveform and reduces the wear of the inverter’s ﬁ lter capacitors.

• Use crimped and sealed copper ring terminal lugs to connect the DC wires to the inverter’s DC terminals. (We use 5/16” terminal lugs here in U.S., determine the European equivalent.)

• The battery bank voltage must match the DC voltage required by the inverter (i.e., 24-volt

battery bank for a 24-volt inverter), or the inverter may be damaged.

• To ensure the maximum performance from the inverter, all connections from the battery bank to the inverter should be minimized. The exceptions are the DC overcurrent disconnect in the positive line and a shunt in the negative line. Any other additional connection will contribute to additional voltage drops, and these extra connection points may loosen during use.

• All wiring to the battery terminals should be checked periodically (once a month) for proper tightness. The torque requirement for the DC terminals is between 13.6 to 16.3 N-m (10 to 12 ft lbf). If you do not have a torque wrench, ensure all DC terminals are tight and cannot move.

• Be aware that overtightening or misthreading the nuts on the DC terminals can cause the bolts to strip and snap/break off.

• Make sure cables have a smooth bend radius and do not become kinked. Place long cable runs in conduit and follow existing wire runs where possible.

• A brief spark or arc may occur when connecting the battery cables to the inverter DC terminals; this is normal and due to the inverter’s internal capacitors being charged.

• Color code the DC cables/wires with colored tape or heat shrink tubing: BROWN for positive (+); BLUE for negative (-); and GREEN (or GREEN w/YELLOW stripe) for DC ground to avoid polarity problems. Refer to Table A-2 (in Appendix A-3) for a list of equivalent DC wiring color codes for Europe and U.S./Canada.
