Frequently Asked Questions
Q
What is a home energy storage system and how does it work?
A
A home energy storage system stores electricity — typically generated by rooftop solar panels — in batteries for later use. It consists of an energy storage battery, an inverter, and a Battery Management System (BMS). The inverter converts DC power from the batteries into AC power for household appliances, while the BMS continuously monitors battery health and safety.
Q
Why is lithium iron phosphate (LFP) the preferred battery technology for home storage?
A
Lithium iron phosphate (LFP) batteries are preferred due to their superior thermal stability, longer cycle life, and enhanced safety compared to other lithium chemistries. They are less prone to overheating or combustion, making them ideal for residential environments where safety is a top priority.
Q
What capacity home energy storage system do I need for my household?
A
Home energy storage systems typically range from 5 to 30 kWh. The right capacity depends on your daily electricity consumption, the size of your solar PV system, and whether you need full off-grid capability or just backup power. For most households, a 10–15 kWh system is sufficient to cover essential appliances during a power outage.
Q
Can I add a battery storage system to my existing solar PV installation?
A
Yes. Retrofit systems are specifically designed for homeowners who already have a solar PV installation and want to add energy storage. These systems are cost-effective and compatible with most existing setups, allowing you to upgrade without replacing your current solar equipment.
Q
How does a home storage system help reduce electricity bills?
A
Home storage systems reduce electricity costs through peak shaving and valley filling — storing cheap off-peak electricity and using it during expensive peak hours. Combined with solar panels, they maximize self-consumption of free solar energy, significantly reducing or even eliminating grid electricity purchases.
Q
Is a home energy storage system suitable for areas with frequent power outages?
A
Absolutely. Home energy storage systems are an excellent solution for areas prone to power outages. Hybrid and off-grid systems can automatically switch to battery power within milliseconds of a grid failure, keeping your lights, appliances, and critical devices running without interruption. Off-grid systems can even be paired with diesel generators for extended backup in remote areas.
