A 40kW photovoltaic (PV) system with an 80kWh hybrid energy storage system was successfully installed in Moldova. The customer required a solution that maximized energy production despite limited roof space while ensuring durability and seamless operation in outdoor conditions.
High-Efficiency PV Modules for 40kW Solar PV System with 80kWh Hybrid Energy Storage
The installation features 72 pieces Kinyvin 600W PV modules, incorporating the latest N-type cell technology . N-type modules are known for their higher efficiency, better low-light performance, and reduced degradation over time compared to conventional P-type cells. This choice ensures maximum power generation even within the spatial constraints of the site.
Flexible Mounting Solutions with 40kW Solar PV System with 80kWh Hybrid Energy Storage
Due to limited roof space, a one-size-fits-all approach was not possible. To overcome this challenge, the installation utilized multiple mounting methods:
– Sloped tile roof mounts :for sections with traditional architecture
– Tilted triangular mounting structures: to optimize panel orientation and sun exposure
– Steel frame mounts: where additional elevation or structural adaptation was required
This combination allowed full utilization of available space without compromising system performance or safety.
All-in-One BESS for Outdoor Use with 40kW Solar PV System with 80kWh Hybrid Energy Storage
Space limitations also dictated the need for a compact yet powerful energy storage solution. A fully integrated Battery Energy Storage System (BESS) outdoor cabinet was selected. Key features include:
– IP65-rated enclosure, providing complete protection against dust and low-pressure water jets
– Built-in air conditioning cooling to maintain optimal battery temperatures in all seasons
– Integrated fire suppression system for enhanced safety
This self-contained unit eliminates the need for a separate equipment room, making it ideal for sites with limited indoor space.
High-Durability Hybrid Inverter for 40kW Solar PV System with 80kWh Hybrid Energy Storage
The system is powered by a Deye 40kW hybrid inverter with 400V three-phase output Designed for outdoor installation, the inverter carries an P68 rating—the highest level of dust and water protection, ensuring reliable operation even in challenging weather conditions. This allows the inverter to be placed directly outdoors without requiring additional shelter.
Scalable Battery Configuration for 40kW Solar PV System with 80kWh Hybrid Energy Storage
Energy storage is delivered through 80kWh of lithium battery capacity, configured using 8 units of 51.2V 100Ah lithium batteries connected in series . A high-voltage control box** manages the series connection, ensuring safe and efficient operation while maximizing the system’s overall performance.
Customer Satisfaction
The customer is extremely satisfied with the system’s performance. The combination of high-efficiency N-type modules, a rugged outdoor-rated inverter, an all-in-one BESS with active thermal management, and flexible mounting adapted to site constraints has resulted in a reliable, low-maintenance, and high-yield renewable energy solution.
