I. SAFETY FIRST

The function of the inverter is to convert DC 12V/24V/48V into AC 110V.
Mxmoonfree’s pure sine wave power inverter has adapted the SPWM technology which makes it highly efficient and reliable.
Incorrect installation or misuse of the inverter may result in danger to the user or hazardous conditions. We urge you to pay special attention to all CAUTION and WARNING statements. CAUTION statements identify conditions or practices that may result in damage to other equipment. WARNING statements identify conditions that may result in personal injury or loss of life.

WARNING! Shock hazard. Keep away from children.

• The inverter generates the same potentially lethal AC power as a normal household wall outlet. Treat it with the same respect that you should have to any AC outlet.
• Do not insert foreign objects into the inverter’s AC outlets, fan or vent openings.
• Do not expose the inverter to water, rain, snow or spray.
• Do not, under any circumstances, connect the inverter to utility power AC distribution wiring.

WARNING! Heated surface.

• The inverter’s housing may become uncomfortably warm, reaching 158 Fahrenheit (70 Celsius) under extended high power operation. Ensure that at least 4 inches (10 cm) of air space is maintained on all sides of the inverter. During operation, keep away from materials that may be affected by high temperatures.
• Do not expose the inverter to temperatures exceeding 113 Fahrenheit (45 Celsius).

WARNING! Explosion hazard.

• Do not use the inverter in the presence of flammable fumes or gases, such as in the bilge of a gasoline powered boat, or near propane tanks. Do not use the inverter in an enclosure containing automotive-type lead-acid batteries.
• These batteries, unlike sealed batteries, vent explosive hydrogen gas, which can be ignited by sparks from electrical connections.
• When working on electrical equipment, always ensure someone is nearby to help you in an emergency. It is recommended that the installation should be undertaken by a qualified, licensed electrician.

CAUTION! Safety Instructions – Inverter Related

• Do not connect live AC power (City power/ Grid Electricity) to the inverter’s AC outlets. The inverter will be damaged even if it is switched OFF.

• Preventing Reverse Polarity on the DC Input Side
  When making battery connections on the input side, make sure that the polarity of battery connections is correct (Connect the Positive of the battery to the Positive terminal of the unit and the Negative of the battery to the Negative terminal of the unit). If the input is connected in reverse polarity, fuse(s) inside the inverter will blow and may also cause permanent damage to the inverter.
  NOTE: Damage caused by reverse polarity is not covered by warranty!

• Preventing connection of the inverter AC side together.
  No stack use of several off grid inverters. Connecting the inverter AC side together will cause the failure of the inverter immediately. No connection to any electrical breaker panel/load center which is also from utility power or generator. The AC power back to the inverter will instantly damage the output section of the inverter, may also cause a fire or safety hazard.

Connection from Batteries to the DC Input Side ­- Sizing of Cables and

Fuses

• The cable for connecting the battery and the inverter will affect the inverter output performance, please use all of the cables supplied in the pack or larger cable. The fuse between the battery and the inverter will also affect the output power. Please calculate the fuse or breaker ampere with this formula inverter power/input voltage1.2.
  For example, if you are connecting a 12V 5000W inverter, then you could conclude that the required fuse or breaker size is 5000/121.2=500A.
  If the power you use is less than 5000W, please use a smaller power substitute to avoid harm to the inverter and appliances; and if you are using inductive load appliances such as pumps, air conditioners, and refrigerators, you should use a slightly larger fuse or breaker as appropriate to avoid tripping.

• Do not overload. Do not use for the appliances with exceeding power capacity than the power inverter’s rated power. Better to use 80% of the rated power of the power inverter for longevity of the power inverter. CAUTION! Pay attention to the inductive load with 3-8 times higher.

• Inductive loads: fans, pumps, electric drills, air conditioners, and refrigerators.

II. TECHNICAL PARAMETERS

III. FRONT VIEW

1. AC Outlets – 110V AC 60Hz. Maximum recommended output per outlet is 1500W.
2. Power LED (Green) – When this green LED is lit, the inverter is operating.
3. Fault LED (Red) – The red indicator turns on as the inverter shuts down due to overheating, overload, under voltage, or over voltage.
4. LCD Display Screen – display a variety of real-time states.
5. ON/OFF Switch – Controls AC output.
6. USB Port – 5 volts / 2.1 A for charging tablets, smartphones and other small electronic devices.
7. High Output AC Terminals – These terminals are for connecting 110 AC devices that require more than 20 amps to operate or for connection to distributed wiring that has multiple AC outlets, 1000W excluded.

Facing the front panel, the terminals are:

IV. REAR VIEW

1. Positive Terminal – Positive (+) DC Input (Red)
2. Cooling Fans – Thermally controlled
3. Negative Terminal – Negative (-) DC Input (Black)

Note: Only the 12V 5000W model has 2 positive and 2 negative terminals.

DC to AC inverters require high amperage/low voltage DC power to low amperage/high voltage AC power. In order to reduce the risk of overheating due to DC side high currents, we set up second terminals on the same side (2 negative, 2 positive) and connect them in parallel. This way, evenly distribute the amperage load.

• Overload protection: when overloading, the inverter will send alarm, and stop working after 20 seconds. Once the loads are reduced to accepted level, the inverter will resume working.
• Short circuit protection: inverter is with short circuit protection.
• Over-heat protection: when the inside temperature of the inverter reach 176 F (80 Celsius), the RED indication light will be on. The inverter will stop working, once the temperature drops to accepted level, the inverter will automatically resume working.
• Low voltage protection: when the battery voltage is below the setting level, the inverter will alarm by beeping. When the battery voltage keeps dropping to its shutting level, the inverter will beep, and the RED light will lit, the inverter will stop working.
• Over voltage protection: when the input voltage is higher than the setting level, the inverter will stop working until the input voltage is normal.
• Reverse connection protection: once there is reverse connection, the Inverter fuse will be burned. In this case, please switch off the inverter, disconnect the power source, change the fuse.

VI. BATTERY REFERENCE

To determine the minimum battery bank ampere-hour rating that you will need to operate appliances from the inverter, and any DC appliances powered by the battery bank, follow these steps:

1. List the maximum wattage that the inverter has to provide. Each electrical appliance has technical specifications indicating the watts, or the volts and amps required for operation.
2. Estimate load run-time – Battery size depends on load watts and run-time. Estimate the number of hours the appliances will be in use. This will differ depending on appliances. As an example, a typical home-use coffeemaker draws 500 watts during its brew time of 5 minutes; it maintains the temperature of the pot at about 100 watts. Typical use of a microwave oven is only for a few minutes. Some longer operating time appliances are lamps, TVs, computers and refrigerator / freezers.
3. Determine the total watt-hours of energy needed. Then multiply the average power consumption in watts by the number of hours of run time. For example: 12V 1500 watts for 10 hours = 15,000 watt hours. Using the 1500 watts (or 125 Amps) for 10 hours example as above, then 125 amps is needed for 10 hours. This provides us with the basic amp-hours (AH) of battery that is required. Ten hours at 125 amps equals 1250 Amp Hours (AH). This answer is just a beginning because there are other conditions that determine actual run time. These include:
   • AC appliance load and time in use (basic Amp Hour)
   • Cable gauge and length (cable losses)
   • Charge level of the batteries (before use, batteries had to be fully charged)
   • Temperature of the batteries (colder batteries provide fewer amps)
   • Age and condition of the batteries (older batteries lose capacity/amp hours)
   • Compliance with turning off unnecessary AC and DC loads.

If there is any doubt about sizing the battery bank, it is safe to overestimate the amp hour requirements of the battery bank.

Note:
The type of batteries you use to power your high power inverter is important. Operating a high-power inverter will routinely discharge batteries and they will require frequent recharging. Batteries used to start engines are not designed to repeatedly charge and discharge. Mxmoonfree recommends using “deep-cycle” or “marine” rated batteries.

The following takes a 12V inverter as an example, the battery bank will be 12 volts direct current (12 V DC)

Example

A induction cooker =1700 Watts 12V battery bank| 1700 Watts to run a 12V induction cooker using the batteries , it requires

1700 Watt / 12 Volt = 141A

Load Operation = 1 hours| Now that amps have been determined, the amp-hours need to be determined. The induction cooker will be used for approximately 1 hours a day.

*141 Amps 1 hours = 174Ah**

VII. INSTALLATION

Getting Started

• When a motorized appliance or a tool turns on, there is an initial surge of power to start. This surge of power is referred to as the “starting load” or “peak load.” Once started, the tool or appliance requires less power to operate. This is referred to as the “continuous load” in terms of power requirements. You will need to determine how much power your tool or appliance requires to start up (starting load) and its continued running power requirements (continuous load).

• Power consumption is rated in watts, or it can be calculated from amperes (amps). This information is usually stamped or printed on most appliances and equipment. If this information is not indicated on the appliance or equipment, check the its manual.

• *AC AMPS 110 (AC voltage) = WATTS**
  This formula yields a close approximation of the continuous load of your appliance.

• *WATTS 2 = Starting Load for most appliances**
  This formula yields a close approximation of the starting load of most appliances. Exceptions are inductive load appliances such as pumps, electric drills, air conditioners, and refrigerators. These appliances can have startup loads of up to eight times the rated watts.

Mounting the Unit

Consider the following points before selecting where to install:

• Do not mount the inverter on flammable construction materials.
• Inverter must be OFF.
• Mount on a solid surface.
• Install this inverter at eye level in order to allow the LCD display to be read at all times.
• The ambient temperature should be between -10°C and 45°C to ensure optimal operation.
• The recommended installation position is parallel on a flat surface.
• Be sure to keep other objects and surfaces as shown in the image below to ensure adequate heat dissipation and enough space for wires to be removed.

Battery Connection

• When connecting the inverter to the battery terminals, it is important to connect the “+” wire to the “+” terminal and the “-” wire to the “-” terminal. Do NOT reverse the polarity. It will void the warranty. Make sure you connect negative to negative and positive to positive.
• Please pay attention to parallel and series connection, the following takes a 12V battery as an example.

How to Connect Batteries

a. 12V Power Bank
b. 12V 3000W+ load with Power Bank

• DO NOT allow the wires to cross or touch each other. Install the cables facing away from each other and screw tightly. When connecting the battery cables to the terminals of the inverter, make sure they do not touch the case.
• Loose connections can result in a severe decrease in voltage that can cause damage to cables and insulation.
• Making the connection to the Positive terminal may cause a spark as a result of current flowing to charge capacitors within the inverter. This is a normal occurrence.
• Because of the possibility of sparking, however, it is extremely important that both the inverter and the 12 volt battery be positioned far from any possible source of flammable fumes or gases. Failure to heed this warning could result in fire or explosion.

Grounding

Grounding wires have been installed inside the inverter, no external grounding terminals are needed.

Operation

1. Before connection, please make sure the inverter is switched off.
2. plug an appliance cord into one of the 110v AC Outlets on the front panel of the inverter and turn it off.
3. Turn on the inverter.
4. Turn the appliance on.
5. Plug in additional appliances and turn them on
