Inverters are a trendy choice for people who need portable power. Considering a 2000w inverter, you will want to know how many devices it can power. This article will help you understand the applications, price, and battery requirements of a 2000w inverter.
2000w inverter working principle
If you want to know how 2000-watt inverters work, it is important to understand the difference between AC and DC. DC flows in a fixed direction from positive to negative and has a constant voltage and current, whereas AC changes direction periodically. DC is usually used for specialist equipment, while AC is widely used in domestic, industrial, and commercial applications.
An inverter is a compact rectangular electrical device that converts voltage from direct current (DC) to alternating current (AC) for use in household appliances. This conversion process is achieved by a series of electronic components (e.g. thyristors, field effect tubes, etc.) and control circuits. Once the inverter has produced AC power, it transmits it to the various appliances connected to it.
2000w inverters receive DC power as an input, this can be from solar panels, batteries, or other DC power sources. A 2000w 12v inverter is compatible with most household appliances and electronic devices. It provides 2000 watts of power output, which is the maximum load it can handle!
Types of 2000w inverter
You already know how an inverter works, and there are two common types you'll come across when buying a 2000w inverter:
2000w pure sine wave inverter
Provides a sine wave output, similar to the power provided by a household socket.
✔️Pros
- Suitable for a wide range of sensitive equipment such as computers, CEL bulbs, sound systems, etc. as the output waveform is stable and similar to mains power.
- The pure sine wave produces a voltage waveform with very low harmonic distortion. This means your equipment will enjoy clean power. Ideal for equipment that requires a high-quality, stable power supply that reduces noise and interference generated by equipment.
❌Cons
Expensive as it works with almost all equipment.
Pure sine wave, 2000-watt inverters are typically priced between $200 and $800. Fortunately, the cost of sine wave inverters has started to come down. This means that they will become more affordable in the coming days.
2000w modified sine wave inverter
The polarity of the Improved Sine Wave Inverter constantly changes from positive to negative. If you look closely at the Improved Sine Wave, you will see that it resembles a stepped shape. It provides an output that approximates a sine wave, but there may be some waveform distortion or voltage pulsation.
✔️Pros
- Prices are usually more affordable than pure sine wave inverters.
- Waveform distortion is acceptable for many household appliances and equipment. A modified sine wave inverter is compatible with many appliances. Some of these devices include mobile phone chargers, old CRT TVs, solar water pumps, etc.
❌Cons
- As the polarity here tends to reverse from time to time, delicate and sensitive equipment may be at risk. Equipment connected or attached to this inverter tends to hum.
- A modified sine wave inverter is less efficient than a pure sine wave inverter because it cannot operate at full load. In addition, a modified sine wave inverter uses up to 30% more power than a comparable product. As a result, it generates excessive waste heat that can damage appliances or equipment in your home.
How many batteries does a 2000w inverter need?
For a 2000w inverter, the number of batteries required depends on the battery voltage and the required running time. The following formula can be used to determine the required battery capacity:
Battery capacity (Ah) = Power (watts) x Time (hours) Battery voltage (volts) x Depth of discharge (DOD) Battery capacity (Ah) = Battery voltage (volts) x Depth of discharge (DOD) Power (watts) x Time (hours)
Once the desired battery capacity in ampere-hours (Ah) has been obtained, the user can select the appropriate battery combination. It is important to note that connecting batteries in series increases the voltage while connecting batteries in parallel increases the capacity. For example, if a 12 lithium battery is used, the required running time is 1 hour and the depth of discharge is 50%:
Battery capacity (Ah) = 2000 x 112 x 0.5 = 83.33 Battery capacity (Ah) = 12 x 0.52000 x 1 = 83.33
In this case, approximately 83.33 Ah of battery capacity is required. The actual number of batteries required will depend on the specific capacity of the battery selected.
What wire size for a 2000W inverter?
Choosing the correct size of wire to connect a 2000w inverter depends on a number of factors, including the current load the wire will carry, the length of the wire, and the environment in which it will be installed.
Current load
For a 2000W inverter, you need to consider its output current. Based on the relationship between power and voltage (power = voltage x current), the maximum output current of a 2000W inverter at 110V is approximately 18A (2000W / 110V = 18.18A).
Wire length
Longer wires increase the resistance of the wire, so a larger diameter wire is required to reduce the voltage drop. The longer the wire length, the larger the gauge (diameter) of the wire must be.
If the distance between the inverter and the batteries is 3 feet or less, you will need a 1/0 gauge wire.
If the distance between the batteries and the inverter is between 3 and 6 feet, make sure the inverter wire is 2/0.
Finally, if the distance between the 2000-watt inverter and the batteries is between 6 and 10 feet, the wire size is 250.
Installation environment
If the cable is to pass through high-temperature areas or places that require physical protection, you must select a cable that meets the requirements of the environment.
If you do not have the appropriate electrical knowledge, it is best to consult a professional before installation.
What can a 2000w inverter run?
A 2000w inverter can power many household appliances and before we look at these appliances, there are a few terms you need to understand: starting power and running power. Running power (also known as nominal power) is the continuous power required by an appliance when it is running continuously. On the other hand, some appliances require an instantaneous power when they are switched on that is greater than the operating power (known as the start-up rate or surge power). Appliances that produce heat or light (e.g. light bulbs, toasters, and microwaves) do not require a higher starting power. However, appliances with motors (e.g. fans and hairdryers) require some extra power to start.
The starting wattage and running wattage can be found on the unit's casing or in the manual, and with these details, you can calculate the minimum wattage required to run these units. This will help you know if a 2000-watt inverter is right for your home!
Assuming you have a 2000-watt inverter, some of the most common appliances and devices are as follows:
- TV: 250w
- Ceiling fan: 140w
- Portable heater: 1200w
- Hair dryer: 800-1600w
- Coffee maker or microwave: 1000w
- Stereo system: 300w
- Fridge: running power 100-400w, start power 800-1200w
- Microwave: running power600-1200w running, start power 1500-1800w
- Washing machine: Running power 300-500w, Start power 800-1200w
With this, you understand - what can a 2000w inverter run? Or what will a 2000w inverter run?
Now that you know what appliances you can power with a 2000-watt inverter, you need to be able to decide which appliances you want to use at the same time and which you can switch off for some time. If the power goes out in your home, you need to make sure that the appliances continue to serve you best. With the right calculations, you can stay comfortable and warm during a power cut.
