Selecting the right storage unit size is one of the most important considerations when designing a system.
Factors that influence the unit capacity include:
Energy consumption
Properties with higher daily electricity use typically require larger storage capacity.
Solar generation
The amount of energy your solar panels produce influences how much energy can realistically be stored.
Usage patterns
Evening energy use often determines battery requirements.
Backup requirements
Properties seeking whole-home backup usually require larger systems than those supporting only essential circuits.
Future expansion plans
Future additions such as:
Electric vehicles
Pool systems
Air conditioning
Home extensions
may increase energy demand.
Storage unit capacity is generally measured in kilowatt-hours (kWh), with residential systems commonly ranging from around 4kWh to 14kWh, although larger systems are becoming increasingly common.
