Project Report 14kw Solar Storage Installation In Yerevan Armenia

The Project at a Glance

Last month, our technical team completed the commissioning of a 14kW solar storage system for a private residence in Yerevan, Armenia. This project focused on providing a stable power supply in a region that experiences both high solar gain and significant seasonal temperature drops.

The Client’s Requirement

The homeowner approached us with two specific needs. First, they wanted to hedge against rising local electricity rates. Second, they needed a solution for the voltage instability common in the suburban Yerevan grid. The goal was simple: build a system that could power the entire house—including the heating system—during winter outages

Technical Configuration

We opted for a 14kW hybrid setup to ensure the house could run high-draw appliances without stressing the inverter.
Battery Bank: We installed a modular LiFePO4 battery array. We chose Lithium Iron Phosphate specifically for its 6,000+ cycle life and its ability to handle deep discharges daily without the rapid degradation seen in lead-acid alternatives.
Inverter: A 14kW hybrid inverter serves as the system’s brain, managing the switch between solar, battery, and grid power in under 10 milliseconds.
Safety Gear: Given the local grid’s fluctuations, we integrated additional surge protection and a dedicated DC breaker box to protect the battery cells.

Real-World Performance

After thirty days of operation, the data from the monitoring app shows the system is performing as expected.
The house now runs almost entirely on solar during daylight hours, while the 14kW storage handles the evening loads. Even on overcast days, the system’s efficiency remains high enough to cover the home’s essential lighting and refrigeration. The client reports that they no longer notice when the local grid fluctuates or drops out
Engineering Insights
One challenge during this Armenian installation was the ambient temperature in the equipment room. To ensure the lithium cells maintain their lifespan, we positioned the battery bank to allow for maximum natural airflow. We also calibrated the BMS (Battery Management System) charge parameters to account for the local climate, ensuring the cells stay within their optimal voltage range.

Final Word

This 14kW project is a practical example of how modern storage technology can solve local utility issues. It’s not about flashy tech; it’s about providing a reliable, 10-year power solution that works when the sun goes down
