To connect the 2000W inverter, you should think about the system effort, the current drawing, and the distance of the battery. Below are the main points that must be understood before checking the wire size scheme:
In 12 volts, the 2000W inverter withdraws about 167 amps, and requires a very thick wire:
On 24 volts, the current decreased to 84 amps:
In 48 volts, the current decreases to 42 amps, so:
The table below lists the recommended copper wire sizes (75 ° C) for various voltages and wire lengths in one direction, with a decrease in voltage less than 3 %.
What will run the reflector 2000W?
A 2000W reflector can handle the most common home appliances and home, as long as the current ongoing force remains under 2000 watts, and does not exceed the increase in the classification of the reflector (usually 3000-4000W).
This is what can actually manage it:
Refrigerator: 150-600W (up to 1200 watts)
Microwave: 700-1000W
Coffee maker: 800-1500 watts
Screen: 800-1500W
TV: 100w
Mobile computer: 100w
LED lamps: 10W per bulb
Fan: 100-500W
Space Heater: 1000-1500 watts
Energy tools (drilling, saw): 600-1200 watts
CPAP machine: 30-60W
Mixer: 300-700W
Small washing machine: 500-1000W
Cooktop Electricity (One Stove): 1000-1500 W.
Now, let’s take a look at example collections:
Morning routine outside the network (~ 1740w total)
Coffee maker: 1000w
Screen: 700w
Phone charger: 10W
LED lamp (1 bulb): 10W
Home Office + Basics (~ 860W Total)
Types of cables and preparation for a 2000w reflector
The reflector turns 2000W continuous current power from a battery to frequency power of the devices. To deliver the 2000W reflector, you need the correct types of cables for:
Battery to the inverter (side of the capital)
Reflecting the loads (AC)
Prepare the solar power panel (if used)
Battery to the inverter (side of the capital)
This connection treats the continuous current power of the battery bank to the insertion of the inverter. The choice of cables depends on the current clouds (up to ~ 167A at 12 volts), flexibility, temperature resistance, and guidance restrictions.
Recommended types of cables:
Welding cable
Very flexible and easy to work in narrow battery cabins
EPDM elastic insulation resists heat, oil, corrosion and moisture
Ideal for the short run to the average in the operations of the settings outside the network, RV, and solar energy where the elasticity of guidance is very important.
Marine battery cable
Long -term canned copper to resist in wet or mobile environments
Dragged PVC insulation
Suitable for boats, trucks and ambushes with moderate weather or vibration
Sergeant battery cable
A common use of auto systems
Flexible PVC insulation
Good for short, attached and protected operation in RVS, trailers and trucks where the minimum bend is
Always install a fabric or cutter closer to the battery station as much as possible to protect the wires in the case of a short circle (for example, a 200A fuse for the 12V 2000w reflector system).
Reflecting the loads (AC)
This is the standard wires 120V or 240V AC. Choose the cable based on the environment, the type of installation, and whether operating requires elasticity, buried, or protected in the channel.
Recommended types of cables:
THN (was cut off)
Used inside the channel for fixed interior wires
The two ways are preferred to the reflector settings because it is so The most flexible and easier way In operating a narrow channel compared to solid wires
Heat -resistant and oil (90 ° C)
Compatible with NEC for permanent facilities in garages, pens, utility rooms, and other dry interior spaces
Relatively cheap
NM-B (romex) – Only internal
Used in dry, protected areas such as the walls of the cabin and ceilings
It has not been classified for wet use or outdoor use
Easy to install for fixed internal circuits without a channel
UF-B- Cable Outdoor or underground
Direct burial ranked and resistant to sunlight and humidity
Used in external wire outlets, separate buildings, or buried feeding
Cable Saoo – Flexible and difficult
Rubber ground is very permanent
Resistant to oil, moisture, corrosion and sunlight
Ideal for portable, temporary or mobile AC
Prepare solar wires (if you use panels)
If your inverter is part of a solar system, you will also need separate DC wires to enter solar energy:
Solar panels to charge the console unit
Use an outdoor approval cable between the solar panels and the shipping control unit:
PV wires
UV rays, heat, and moisture resistance
Compatible with NEC for non -plated or terrestrial systems
Suitable for long open air operation
Recharge the control unit to the battery
Use the same type of cable as is the case from the battery to the inverter:
Welding cableand Marine battery cableOr Censor
The scale depends on the current clouds and the length of operation (for example, 4 AWG or more thickness)
