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 (usually LFP) for use during the night, cloudy days, or grid outages. It works alongside an inverter and BMS to manage charging, discharging, and power conversion automatically.
Q What is the typical storage capacity for a residential system?
A Residential energy storage systems typically range from 5 to 30 kWh. The right capacity depends on your household's daily energy consumption, the size of your solar array, and whether you want full off-grid capability or simply backup power support.
Q What is the difference between a hybrid system and an off-grid system?
A A hybrid system remains connected to the utility grid and uses stored energy to supplement or back up grid power, making it suitable for most urban and suburban homes. An off-grid system operates entirely independently from the grid and is designed for remote locations or areas with unreliable electricity supply, often paired with a diesel generator as a backup.
Q Why is lithium iron phosphate (LFP) the preferred battery chemistry?
A LFP batteries are preferred for home energy storage because they offer superior thermal stability (reducing fire risk), a long cycle life (typically 3,000–6,000+ cycles), and consistent performance over a wide temperature range. Compared to lead-acid batteries, they are lighter, more efficient, and require minimal maintenance.
Q Can I add energy storage to my existing solar PV system?
A Yes. Retrofit systems are specifically designed to integrate with existing PV installations. They are cost-effective and compatible with most inverter brands, allowing homeowners to upgrade without replacing their current solar setup. A qualified installer can assess compatibility and recommend the best retrofit solution.
Q How does a "PV + Storage" system reduce electricity bills?
A A PV + Storage system reduces electricity costs in two main ways: first, by maximizing self-consumption of free solar energy instead of drawing from the grid; and second, through peak shaving and valley filling — charging batteries during off-peak (low-tariff) hours and discharging during peak (high-tariff) hours to minimize expensive grid consumption.
