Virtual Central approach of PV string inverters – a cost benefit Compared to the traditional mounting arrangement where the inverter is fixed decentral at the end of each PV string the so called virtual central offers many benefits.
Adding capacity in photovoltaic plants is a core part of the energy transition. Investment in PV plants therefore needs to be made as attractive as possible for operators. In order to make the planning, construction and operation of PV systems more economical, the centralized string inverter concept was developed.
If it is intended to install high power PV modules (500+ Wp) with DC current ratings of >13 A, only one of the two DC inverter inputs can be utilized. Consequently, fewer PV modules can be connected to the inverter. The corresponding output therefore demands for more inverters to be installed.
Central inverters convert power on multiple strings of connected solar panels. They are rated from around 600 kW to 4000 kW. Central inverters typically rely on single-stage power conversion, and most inverter designs are transformer-based or isolated. In the DC-AC stage, variable DC is converted to grid-compatible AC power.
The decentralized inverters are directly installed at the PV module substructure with two strings to one DC inverter input and connected via 3-phase underground cables to the AC station. No combiner boxes or separate inverter racks are required – only the mounting of the inverters.
Which replaces a central inverter with multiple string inverters centralized in one place. The string inverters are installed at a central location in the ground-mounted PV system, while the DC combiner boxes are distributed in the field near the panels.
The European energy storage market is booming with Germany leading residential adoption (+58% YoY) thanks to €500/kWh subsidies. Italy's new tax credits drive 5.2GWh commercial deployments, while UK grid-scale projects exceed 8GWh with 2-hour duration systems. Key selection criteria: German-certified safety (VDE-AR-E 2510), 10+ year warranties, and VPP readiness. Top-performing products include Sonnen's hybrid inverters (98% efficiency) and BYD's Blade Battery (12,000 cycles @80% DoD). For snowy regions like Scandinavia, consider Huawei's -30°C compatible systems. France mandates carbon footprint declarations - Sungrow's ISO-14067 certified solutions gain preference.
For European homeowners, 5-10kWh systems with 3-phase compatibility are ideal. Top picks: 1) Tesla Powerwall 3 (13.5kWh, 97% round-trip efficiency) for smart home integration; 2) LG Chem RESU Prime for compact urban installations; 3) SMA Sunny Boy Storage for retrofit projects. Critical features: EU-made battery cells (exempt from CBAM tariffs), dynamic tariff optimization (like Octopus Energy integration), and fire-safe LiFePO4 chemistry. Southern Europe demands 85%+ depth of discharge capability, while Nordic markets require -25°C operation. Always verify CEI 0-21 compliance for Italian grid connection and EnWG certification for German feed-in.
