Portfolio

A well-thought-out photovoltaic system is more than an investment in technology – it is an important step towards energy independence. The proposed package, with an installed power of 5 kWp, is designed to provide efficiency, reliability and flexibility in a complete solution, adapted to modern homes and residential spaces with high energy needs.

The system was configured taking into account the requirements of a beneficiary who wanted a high level of autonomy from the grid, considering the instability of the current in the living area. The chosen solution includes premium components – Bauer PV panels, Victron EasySolar inverter, K2 clamping structure and an Ecosolaris LiFePO4 battery – all working together in a balanced, efficient and scalable system.

System components

Bauer 450W photovoltaic panels – German efficiency in every cell

I am at the base of the system 12 Bauer 450W solar panels, which provides a total installed power of 4.95 kWp. The half-cut technology used in these panels allows for better performance even in partial shading or low irradiance conditions. High efficiency, durability and quality of construction make Bauer panels a safe choice for those who want long-term results.

The beneficiary opted for these panels due to their reliability and extended warranty: 25 years on performance și 15 years on the product. An ideal solution for someone looking for a balance between efficiency and durability.

K2 Systems mounting structure – Stability and adaptability

The panels are mounted on a structure K2 Systems, known for its robustness and flexibility. The system is configured for pitched roofs, but can easily be adapted for terraces or other types of surfaces. The materials used – anodized aluminum and stainless steel – guarantee long-lasting resistance, including in difficult weather conditions.

The structure is designed for two separate strings, which allows for optimal energy distribution and easy maintenance.

Victron Energy EasySolar 48/5000 inverter – Smart power in one device

The central component of the system is the inverter Victron EasySolar 48/5000, an all-in-one device that integrates:

• MPPT SmartSolar 250/100 regulator
• AC/DC distribution panel
• Intelligent monitoring interface

This compact solution offers not only efficient energy conversion, but also automatic management of power sources – panels, battery, mains or generator. It is ideal for homes that want to combine their own energy production with smart storage and emergency backup.

The customer chose this inverter because of Victron's reliability and the ability to remote monitoring through the platform Victron VRM, which ensures total control over the entire system, from anywhere.

DC protection panel – Safety at the heart of the system

For plant and equipment protection, the system includes a full array of DC protections, sized for the two strings. It contains:

• Surge Arrester (SPD)
• Fuses and circuit breakers
• Load separators
• IP65 housing, water and dust resistant [#$$#]

This component is essential for the safety of the whole assembly, respecting the rules IEC/EN in force.

Ecosolaris LiFePO4 battery 15 kWh – Energy available non-stop

To store the energy produced and use it when the panels are not generating (at night or on cloudy days), the system includes a 15 kWh Ecosolaris LiFePO4 battery. With a lifetime of over 6000 cycles at 80% discharge, this battery is ideal for consistent daily use.

Main features:

• Capacity: 15 kWh / 48V
• LFP (Lithium Iron Phosphate) technology – superior safety
• Full integration with Victron via BMS with CAN/RS485 communication
• Expandable according to future needs

The battery provides a high level of autonomy, and the customer benefits from constant energy, including during periods of no sun or in the event of power outages.

Practical Application – Customer Case

The system has been sized for a residential home in an area where the mains power supply is unstable. The owner wanted a system that would allow him total autonomy, but also an efficient way to monitor and optimize consumption.

In addition to daily use, a priority was protection against unannounced power outages, which is why the storage solution was considered essential. In addition, the customer plans to integrate an electric car charging station and a heat pump in the future, made possible by the flexibility offered by the Victron platform.

Advantages of the 5 kWp photovoltaic system with storage

✅ Significant savings on the energy bill – up to 90%
✅ Full energy autonomy, including in case of power outages
✅ Intelligent monitoring, in real time, from anywhere
✅ Silent operation and without major maintenance
✅ Flexibility – the system can be extended at any time
✅ Minimal impact on the environment – 100% renewable energy

Conclusion

This 5kWp PV system, configured for home consumption and self-storage, is an inspired choice for those who want it safety, economy and autonomy. The selected components – Bauer, K2, Victron and Ecosolaris – together offer a high-performance system, ready to meet today's requirements, but also the energy challenges of the future.
