❓ Frequently Asked Questions
Q What is a home energy storage system and how does it work?
A home energy storage system stores electricity generated by solar panels or from the grid during off-peak hours. It uses an inverter to convert DC power to AC power for household use, while a BMS monitors the battery in real-time to ensure safe and efficient operation.
Q Why is Lithium Iron Phosphate (LFP) the preferred battery technology?
LFP batteries are preferred due to their superior thermal stability, longer cycle life (typically 3,000–6,000 cycles), and enhanced safety compared to other lithium-ion chemistries. They are less prone to overheating, making them ideal for residential applications.
Q What capacity of energy storage system do I need for my home?
Home energy storage systems typically range from 5 to 30 kWh. The right capacity depends on your daily electricity consumption, the size of your PV system, and whether you need full off-grid capability or simply backup power during outages. A 10–15 kWh system is sufficient for most average households.
Q Can I add a storage system to my existing solar PV installation?
Yes. Retrofit systems are specifically designed for this purpose. They are compatible with most existing PV setups and offer a cost-effective way to upgrade your solar installation with energy storage capabilities without replacing your current equipment.
Q What is peak shaving and how does it reduce electricity costs?
Peak shaving involves using stored energy during high-demand (peak) hours when electricity rates are expensive, and recharging the battery during low-demand (off-peak) hours when rates are cheaper. This strategy — also called "valley filling" — significantly lowers monthly electricity bills.
Q Is a home energy storage system suitable for areas with frequent power outages?
Absolutely. Home energy storage systems provide seamless emergency backup power during grid failures. Hybrid and off-grid systems are especially well-suited for areas with unreliable grid access, and off-grid models can even be paired with diesel generators for extended backup capability.
