Since technology is advancing every day, the world is looking for a more eco-friendly solution to meet its needs and from a South African perspective load shedding has sped up the need to have your power powered by more than the grid.
The inverter is the core product of solar energy systems that converts the DC energy into AC energy. It creates a great power system and a great energy source. The power inverters are eco-friendly solar power systems and the environment and the inverter has great power and battery bank! The most common sizes for a household are 3KW and 5KW.
The capacity and the appliances for both loads are different, and their backup time varies as well. If you're wondering which size system to get for your home, let's break down what each system can carry.
We are assessing the Inverters based on the following systems:
3KW Inverter, 2x Lith-ion 120AH 12V Batteries, 3 x 455W Solar Panels.
5KW Inverter, 5.12KW Lith-ion Battery, 6x 455W Solar Panels
3KW Inverter Setup:
Inverter Capacity: 3KW
Battery Capacity: 2 120AH 12V = 2.88KWh
Solar Panels: 3 * 450W = 1.36KW
Possible Appliances:
Lights (LEDs typically consume around 10-15 watts each)
Fans (Ceiling fans typically consume around 50-75 watts each)
Television (Depends on size and model, but generally modern LCD/LED TVs consume around 100-200 watts)
Laptops (Around 50-100 watts)
Chargers for smartphones, tablets, etc. (Relatively low power consumption, typically less than 50 watts each)
Small kitchen appliances like blenders, coffee makers, toasters, etc., depending on their power ratings and usage duration.
5KW Inverter Setup:
Inverter Capacity: 5KW
Battery Capacity: 5.12KWh
Solar Panels: 6 * 450W = 2.73KW
Possible Appliances:
All appliances listed under the 3KW setup.
Refrigerator (Typically consumes around 100-800 watts, depending on size and efficiency. More efficient models may consume less power.)
Microwave oven (Typically consumes around 700-1200 watts)
Air conditioner (Small window or portable units typically consume around 500-1500 watts, central air systems may require significantly more)
Washing machine (Around 500-1000 watts)
Electric oven or stove (Typically consumes around 1000-5000 watts, depending on the heat setting and duration of use)
In conclusion, we hope you can decide on what's best for your solar needs. Ensure that your solar system is installed correctly and comes with C.O.C so that your home is in line with insurance needs.
