Battery capacity depends on user needs


There are many things to take into account when looking at an energy storage battery for your home or business. These include what you want your energy storage battery to do as well as its safety, performance, operating temperature and end of life recyclability.

Unfortunately many people only look at the initial purchase cost of batteries and this is what they use to compare different batteries. This doesn’t take into account what a battery may cost them over its lifetime or the cost to the environment of both the battery’s manufacture and end of life disposal. To make a realistic comparison of a battery’s cost you need to consider it’s full “cradle to grave” impact on all areas, including its safety during operation and it’s environmental impact.

One of the first things you need to consider is what you want your battery to do. Do you just want to shift some power to be used at night or do you want to be energy independent, even if you stay connected to the grid? The answers to this question may help to determine the size of the battery you need.

To do this you need to look at the way you live and the way and times you use power. If you only want to shift some of the solar PV power generated during the day to be used at night you won’t need as large a battery as you will if you want to become energy independent or even to take yourself off the grid, you also have to consider the way you live as you will no longer have a limitless supply of power (not that we do in reality anyway).

Generally the more appliances you use and the longer you want your batteries to last for the larger battery you will need.

A 3.65 kWh battery is really just a load shifting battery for low energy users but can be a point of entry into the market. As SoNick batteries don’t degrade you can start with a smaller capacity battery and add more batteries as needed, however in terms of value for money the 9.6 kWh SoNick battery is the best battery to use.
