The costs for home Battery Energy Storage systems depend on the battery size or capacity, measured in kilowatt-hours (kWh), and the brand of the solar or hybrid inverter used.
Average household Battery Energy Storage costs between $ 4,000 for a small 4 kwh battery and up to $ 15,000 or more for a large 13 kWh battery, depending on the battery storage, the installation location, the emergency electricity claims, and the interchangeable type used. The costs have dropped slowly, but not as quickly as many had hoped.
Depending on the amount of Battery Energy Storage capacity (measured in kWh) and the type of the required solar inverter, the costs can also vary greatly depending on the amount of energy storage capacity. These inverters are all available in different nominal services (KW) to be suitable for different applications depending on the permanent and top performance requirements.
To give some perspective: An average house with 3 bedrooms consumes about 20 kWh of electricity per day. However, part of this energy is used up during the day and could be fed directly by solar energy. Every household is different and the usage patterns can be very different. Those who are energy-conscious and use efficient devices consume less than 5-6 kWh per day.
We have to take into account the installation costs, the inverter costs or the need for separate lines or the need to update your meter box (circuit package).
The location of the Battery Energy Storage is also important, and in some households, special housings or covers may have to be installed to protect the battery stores. In front of extreme weather conditions and direct sunlight, which can lead to overheating and shutdown. In some cases, the guarantee can become invalid if the battery is not installed in a half -protected place.
You should also concentrate on the shorter winter months to ensure that you have enough excess solar energy to charge the battery in winter.
