Background
With the growth of renewable energy, especially rooftop solar, households increasingly need reliable battery storage solutions. A European installer sought a high-performance 48V lithium battery for residential customers who wanted to reduce electricity costs and ensure backup power during outages.
The Challenge
The installer’s customers had several key requirements:
-
Compatibility with solar inverters already in use.
-
High cycle life to ensure long-term investment value.
-
Safe operation for residential environments.
-
Scalable capacity to meet different household consumption patterns.
Traditional lead-acid batteries failed to meet expectations due to short lifespans, heavy weight, and limited usable capacity.
The Solution
We provided a 48V LiFePO₄ battery pack designed specifically for home energy storage:
-
Capacity: 48V 200Ah (expandable).
-
Cycle Life: Over 6,000 cycles at 80% depth of discharge.
-
Safety: Advanced Battery Management System (BMS) with protections for over-voltage, over-current, and temperature.
-
Integration: Seamless connection with mainstream inverters, making it easy for installers to deploy.
-
Scalability: Modular design allows multiple units to be connected in parallel for larger energy demands.
Results & Benefits
-
Reduced Energy Costs: Homeowners stored excess solar energy during the day and used it during evening peak hours, cutting electricity bills by up to 40%.
-
Backup Power: Ensured uninterrupted supply for essential loads (lights, Wi-Fi, refrigerators) during power outages.
-
Eco-Friendly: Enabled greater self-consumption of renewable solar energy, supporting sustainability goals.
-
Customer Satisfaction: The installer reported higher client satisfaction and referrals after switching to lithium solutions.
Customer Feedback
