Background

A homeowner in California, USA, wanted to reduce electricity bills and secure backup power during frequent outages caused by extreme weather. Relying solely on rooftop solar panels often led to wasted daytime energy, as excess electricity could not be stored for nighttime use.

The Challenge

The customer needed a complete solar energy storage solution that could:

• Store excess solar power for use after sunset.

• Provide reliable backup during blackouts.

• Support essential household loads such as lighting, refrigerator, internet router, and medical devices.

• Operate safely in residential environments with minimal maintenance.

The Solution

We installed a Solar Energy Storage System built around a 48V 200Ah LiFePO₄ battery pack combined with:

• 8 kW rooftop solar panel array.

• Hybrid inverter (5 kW) capable of grid-tied and off-grid operation.

• Smart energy management system to prioritize battery charging and household loads.

The 48V LiFePO₄ battery provided 10.24 kWh of usable storage capacity, offering high efficiency, long lifespan, and superior safety compared to lead-acid alternatives.

Results & Benefits

 1.Self-Consumption Increased: 70% of generated solar power is now used directly in the household, reducing grid dependence.

 2.Reliable Backup: During outages, the system provides up to 12 hours of continuous backup for essential appliances.

 3. Long Lifespan: Over 6,000 cycles at 80% depth of discharge, ensuring more than 10 years of reliable operation.

 4.Environmental Impact: Reduced annual carbon emissions by an estimated 2.8 tons compared to grid-only consumption.

Customer Feedback

"The solar energy storage system gives us peace of mind. We save money every month, and we never worry about blackouts. It’s a clean, quiet, and reliable solution for our family."
