Project Overview
In a medium-sized household located in Eastern Europe, Easun Power deployed a scalable hybrid energy system. The installation used two 6.2 kW hybrid inverters in parallel, paired with a 20 kWh lithium battery bank, to provide both higher power output and longer backup capacity.
System Configuration
-
Inverters: 2 × Easun Power 6.2 kW hybrid inverters (parallel operation)
-
Battery: 20 kWh LiFePO₄ energy storage
-
Total Power Capacity: 12.4 kW
-
Total Energy Storage: 20 kWh
Application Scenario
-
Household + Small Workshop – Covers daily household electricity needs (lighting, appliances, heating system) plus workshop loads such as power tools and equipment.
-
Backup Power – Provides reliable backup for more than 12 hours under typical residential loads, ensuring energy security during outages.
-
Load Flexibility – The parallel inverter design allows stable operation of larger appliances like air conditioning units, pumps, or electric ovens.
Highlights of the Installation
-
Scalable Design – Parallel inverter operation increases power capacity, making it suitable for high-demand households or small businesses.
-
Extended Backup Time – The 20 kWh battery supports long-duration usage, especially valuable in regions with frequent or prolonged grid interruptions.
-
Smart Energy Management – The hybrid system automatically prioritizes solar consumption, stores excess in the battery, and switches seamlessly during grid failures.
-
Future-Proof – System can be further expanded with additional batteries or PV capacity as energy demand grows.
Customer Feedback
“With two inverters running in parallel, we can easily power our household and workshop. The 20 kWh storage gives us peace of mind, even during long blackouts.”
Conclusion
This project demonstrates how a dual-inverter + large battery system delivers both high power output and long-duration backup, making it ideal for energy-intensive households and small businesses.
