❓ Frequently Asked Questions
Q1.
What is a home energy storage system and how does it work?
A home energy storage system stores electricity — typically generated from solar panels — in batteries for later use. It uses an inverter to convert DC power to AC power and a BMS to monitor and protect the battery, allowing households to use stored energy during outages or peak-rate periods.
Q2.
Why is lithium iron phosphate (LFP) the preferred battery technology?
LFP batteries are preferred due to their superior thermal stability, long cycle life (often 3,000–6,000+ cycles), and high safety profile compared to other lithium chemistries. They are well-suited for residential applications where safety and longevity are critical.
Q3.
What capacity of home energy storage system do I need?
For most households, a system between 5–15 kWh is sufficient to cover essential daily energy needs and provide overnight backup. Larger homes or those with higher consumption may opt for systems up to 30 kWh. It's best to assess your average daily electricity usage before choosing a capacity.
Q4.
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 system to include battery storage without replacing your current solar equipment.
Q5.
What is peak shaving and valley filling, and how does it save money?
Peak shaving refers to drawing from stored battery power during high-tariff peak hours instead of the grid, while valley filling means charging the battery during low-tariff off-peak hours. This strategy reduces the amount of expensive peak electricity you consume, lowering your overall electricity bill.
Q6.
Are home energy storage systems suitable for areas without grid access?
Absolutely. Off-grid systems are specifically engineered for locations without access to the public electricity grid. They can be paired with solar panels and, if needed, diesel generators to ensure a continuous and reliable power supply regardless of location.
