It CANNOT connect the red and yellow or black and yellow line to power the load.
  • Do not expose the inverter to temperatures exceeding 104℉ (40 ℃).

CAUTION! SAFETY INSTRUCTIONS – INVERTER RELATED

  • 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, DC 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. Unstackable. No stack use of several off grid inverters. Connecting the inverter AC side together will cause the failure of the inverter immediately. No AC output connection in series or in parallel. The AC output of the inverter cannot be synchronized with another AC source. 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 amper with this formula inverter power/input voltage * 2.

  • Do not overload. Do not use for the equipment’s 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. Pay attention to the inductive load with 5-10 times higher.

4.6     AC SIDE CONNECTION

Make sure the inverter power switch is in the OFF position. Connect the inverter to a fully charged battery or battery bank. Connect the electric appliance to AC output socket of the inverter.

Turn the inverter “ON” – the blue LED should light up, indicating power is on and inverter is functional. Turn on the Appliance.

When finished, turn off the appliance firstly, then turn inverter power switch to “OFF” position, this will shut down the inverter.

Note: When using wired remote controller make sure the inverter “ON/OFF” Switch is in the “ON “position.

IMPORTANT: Vehicle batteries are  designed to provide brief periods of very high current needed for engine starting. They are not intended for constant deep discharge. Regularly operating the inverter shortens the life of the battery. Consider connecting the inverter to a separate deep discharge type battery if you will be frequently running electrical products for extended periods of time.

4.7     INVERTER LOAD REFERENCE:

RATED CONTINUOUS POWER:

This rating may be specified as “Active Power” in Watts (W) or “Apparent Power” in Volt Amps (VA). It is normally specified in “Active Power (P)” in Watts for Resistive type of loads that have Power factor =1. Reactive types of loads will draw higher value of “Apparent Power” that is the sum of “Active and Reactive Powers”. Thus, AC power source should be sized based on the higher “Apparent Power” Rating in (VA) for all Reactive Types of AC loads. If the AC power source is sized based on the lower “Active Power” Rating in Watts (W), the AC power source may be subjected to overload conditions when powering Reactive Type of loads.

SURGE POWER RATING:

During start up, certain loads require considerably higher surge of power for short duration (lasting from tens of milliseconds to few seconds) as compared to their Maximum Continuous Running Power Rating. The inverter continuous power should be higher than the surge power rating of these appliances. Some examples of such loads are given below:

ELECTRIC MOTORS: At the moment when an electric motor is powered ON, the rotor is stationary (equivalent to being “Locked”), there is no “Back EMF” and the windings draw a very heavy surge of starting current (Amperes) called “Locked Rotor Amperes”(LRA) due to low DC resistance of the windings. For example, in motor driven loads like Air-conditioning and Refrigeration Compressors and in Well Pumps (using Pressure Tank), the Starting Surge Current / LRA may be as high as 10 times its rated Full Load Amps (FLA) / Maximum Continuous Running Power Rating. The value and duration of the Starting Surge Current / LRA of the motor depends upon the winding design of the motor and the inertia / resistance to movement of mechanical load being driven by the motor. As the motor speed rises to its rated RPM, “Back EMF” proportional to the RPM is generated in the windings and the current draw reduces proportionately till it draws the running FLA / Maximum Continuous Running Power Rating at the rated RPM.

Transformers (e.g. Isolation Transformers, Step-up / Step-down Transformers, Power Transformer in Microwave Oven etc.): At the moment when AC power is supplied to a transformer, the transformer draws very heavy surge of “Magnetization Inrush Current” for a few millisecs that can reach up to 10 times the Maximum Continuous Rating of the Transformer.

Devices like Infrared Quartz Halogen Heaters (also used in Laser Printers)/ Quartz Halogen Lights / Incandescent Light Bulbs using Tungsten heating elements: Tungsten has a very high Positive Temperature Coefficient of Resistance i.e. it has lower resistance when cold and higher resistance when hot. As Tungsten heating element will be cold at the time of powering ON, its resistance will be low and hence, the device will draw very heavy surge of current with consequent very heavy surge of power with a value of up to 8 times the Maximum Continuous Running AC Power.

AC to DC Switched Mode Power Supplies (SMPS): This type of power supply is used as stand-alone power supply or as front end in all electronic devices powered from Utility/ Grid e.g. in audio/video/ computing devices and battery chargers. When this power supply is switched ON, its internal input side capacitors start charging resulting in very high surge of Inrush Current for a few milliseconds. This surge of inrush current / power may reach up to 15 times the Continuous Maximum Running Power Rating. The surge of inrush current / power will, however, be limited by the Surge Power Rating of the AC source.

FAQ, FREQUENTLY ASKED QUESTION

6.1.    What is the difference of pure sine wave inverter and modified sine wave inverter.

Modified sine wave inverter use less elaborate switching and filtering circuitry. There would be electrical noises or interference which can prevent these inverter from properly powering certain loads. The frequency and voltage to their outputs may vary and contain some noise and distortion. It can run some resistive load like light bulb etc. But it is not good for many appliances and affects use life of the appliances.

Pure sine wave inverter produces the pure sine wave power which is as good as the grid power. With today’s technological advancements, there are more electronics which require true sine wave power to operate correctly. Pure sine wave inverters are designed to emulate the power. Some appliances require pure sine wave, including computers, digital clock, battery charger, light dimmers, auto and visual equipment, variable speed motors, pump, air conditioner, and precision machines, induction cooker, micro wave oven, compressor, water pump, etc. Pure sine wave inverters have distinct advantage over modified sine wave inverters in terms of performance, power consumption. Choose pure sine wave inverter for the goodness and longevity of your appliances.

6.2.    How to choose a suitable power of inverter?

It depends on the power of the appliances. Choose the power inverter based on the maximum power of the AC load. For resistive load such as cooker for 800w, choose1000W inverter. For inductive load such as refrigerator, A/C, pump, motor, compressor etc., the surge power can be 5-10 times higher. Please choose the power inverter with the power of 5-10 times or higher.

6.3.    How long can the power inverter last to power up my appliances?

It depends the power of the AC appliances and the capacity of the batteries. For example, for a 12V,100Ah battery to power up an appliance of 300W. Theoretically, the working time=12V100AH0.8*0.9/300w=2.88hours. Note: 0.8 is the battery discharge coefficient,0.9 is the inverter’s conversion efficiency)

6.4 How to connect the batteries? 6.4.1Series Connection

When two or more batteries are connected in series, the voltages will add up but their Ah capacity remains the same. Please see the chart. When the 4 pcs of 6V, 200Ah batteries connected in series, a battery bank of 24v with a capacity of 200Ah will be made.

6.4.2  Parallel Connection

When two or more batteries are connected in parallel, the voltage will remain the same but their Ah capacity will add up. Please see the chart. When the 4 pcs of 12V, 100Ah batteries connected in parallel, a battery bank of 12v with a capacity of 400Ah will be made.

6.4.3  Series Parallel Connection

The following chart shows a series- parallel connection consisting of four 6V, 200AH batteries to get a 12V, 400Ah battery bank. For string 1, two 6v, 200ah batteries are connected in series to get a 12v, 200Ah battery. Do the same to have string 2. The 2 strings are connected in parallel to have 12v,400Ah bank.

Is this product really 15″ wide? It doesn’t appear so in the pictures.****

OK I just went and measured my unit it is 15 and 3/4 of an inch from front to back that is from the plug in from the plug in to the cables in the back it is 9 and a 1/2 inches wide including 258″ flanges injures which stick ostick out from an 8 and a quarter inch Box And then it is also about 4″ high slightly less.

Connecting to 50a subpanel. does this actually output 66a ac?****

I wondering about the product because I have ordered and paid for three 5000W 12V Pure Sine Inverter. Two of the three times I have received a lesser inverter (3500W) than what I paid for.

On the terminal block is the earth number 1 screw is ground?****

The yellow is the ground on the 5000 watt model.

Is it automatic?****

Yes, pretty much! As long as you have a sufficient battery controller, everything is working fine!

is this a brand new own and I see other one on this use for 386. used can you get a 3-Year Protection for on the used own****

It didn’t appear that there are warranties offered of the used ones. I have had these fail before. You definitely want the 3-year warranty!

Can I operate my 20 amp cutoff saw with this unit since it states it’s 5000 watts?****

You should be totally fine since it will handle a 10000 watt temporary surge and that is a theorical 80+ amp surge capability.

Is it possible to connect L1 and L2 to hot terminal if 240v appliances are disconnected?****

this inverter is 120vac version, it can only be connected to one hot wire.

How long is the warranty ?****

So it comes with a 1 year warranty. I’ve had 2 of these fail on me now. I strongly recommend getting the extended warranty. One was a 3500W invertor that failed after 2 years. The extended warranty worked great. They couldn’t fix it so they gave me a full refund. I then bought the 5000W unit and it failed within 4 months. Same deal. They couldn’t fix it and gave me a full refund again. I have my original 2500W unit I bought from them 4 years ago and it still works fine. It serves as my backup unit. My 2nd 5000W unit is still running (for 4 months now).

can you use this unit with solar panels to charge up batteries and what mppt controller would be compatible with the unit??****

your mppt charges the batteries the inverter changes dc to ac do more research.

How long are the cables?****

20 inches long.

What gauge ac wire should I use for 5000w to connect to sub panel?****

I’m using #6 ga. wire which works fine for potential surges up to 60 amps.
