Voltsmile in the Netherlands: A Solar Energy Storage Case

In the Netherlands, the pursuit of sustainable energy solutions has led to an innovative solar energy storage project using Voltsmile products.

I. The Setup

1. Inverter Selection
   • A 12kW Deye 3-phase hybrid inverter was chosen for this project. The Deye inverter is well-known for its efficiency in converting DC power from solar panels to AC power for use in the electrical grid or for on-site consumption. Its three-phase capabilities make it suitable for larger-scale applications, such as commercial or industrial settings, as well as for some high-demand residential applications.
2. Voltsmile Battery System
   • The 20kWh Voltsmile V10 RPC battery system forms the heart of the energy storage solution. This battery system is designed to store the excess energy generated by the solar panels during peak production times. The V10 RPC battery system offers high-density energy storage, allowing for a significant amount of energy to be stored in a relatively compact unit. It also has advanced battery management features that ensure the long-term health and performance of the battery, such as over-charge and over-discharge protection.
3. SolarEdge PV Inverter Integration
   • The integration of the SolarEdge PV inverter further enhances the overall performance of the system. SolarEdge is a leading provider of solar inverters known for their high-efficiency power conversion and advanced monitoring capabilities. By integrating the SolarEdge PV inverter with the Deye inverter and the Voltsmile battery system, the system can optimize the power flow from the solar panels to the battery and then to the electrical grid or the end-use appliances.

II. The Operation

1. Solar Energy Generation
   • During the day, the solar panels generate electricity. The SolarEdge PV inverter efficiently converts the DC power from the solar panels into AC power. This AC power is then used to meet the immediate energy demands of the building or facility. Any excess power that is not immediately consumed is sent to the Voltsmile V10 RPC battery system for storage.
2. Energiatárolás és -gazdálkodás
   • The Voltsmile V10 RPC battery system stores the excess energy. The battery management system within the V10 RPC monitors the state of charge, temperature, and other important parameters of the battery. This ensures that the battery is charged and discharged in an optimal manner, maximizing its lifespan and performance. When the energy demand in the building or facility exceeds the power being generated by the solar panels, the battery system can discharge the stored energy to supplement the power supply.
3. Grid Interaction
   • The 12kW Deye 3-phase hybrid inverter plays a crucial role in managing the interaction between the on-site power generation (solar panels and battery) and the electrical grid. It can control the flow of power to and from the grid, allowing for functions such as grid-tied operation, where excess power can be sold back to the grid, or off-grid operation in case of a grid outage. The inverter also ensures that the power quality meets the grid requirements, such as maintaining the correct voltage and frequency.

III. The Benefits

1. Energy Independence
   • The solar panels, Voltsmile battery system, and inverters offer energy independence. In the Netherlands, where electricity prices are high, this system reduces reliance on the grid. Storing excess solar energy allows using it during peak demand or when solar panels are inactive.
2. Cost Savings
   • Over time, the system can lead to substantial cost savings. The user can reduce their electricity bills by using stored solar energy instead of purchasing electricity from the grid. Additionally, in some cases, the user may be able to earn money by selling excess power back to the grid. The durability and efficiency of the Voltsmile V10 RPC battery system enhance long-term cost savings, as it requires less maintenance and replacement compared to some other battery technologies.
3. Environmental Impact
   • This solar energy storage solution has a positive environmental impact. Using solar energy as the primary power source and storing it efficiently reduces reliance on fossil fuels. In the Netherlands, this project aligns with the goal of a sustainable energy future by cutting carbon emissions.

The integration of 12kW Deye 3-phase hybrid inverter, 20kWh Voltsmile V10 RPC battery system, and SolarEdge PV inverter in the Netherlands is a successful and sustainable energy solution. It provides energy independence, cost savings, and environmental benefits.
