1-phase
In photovoltaics, the term "single-phase" refers to the type of alternating current generated. A single-phase inverter converts the direct current generated by the solar panels into alternating current, which has only one voltage fluctuation per cycle.
Applications:
- Smaller systems: Single-phase inverters are particularly well-suited for smaller photovoltaic systems with a capacity of up to 6 kWp. These systems typically cover the self-consumption of a single-family home.
- Simple installation: Installing single-phase systems is usually simpler and more cost-effective, as connecting to a household's single-phase power grid is straightforward.
Advantages:
- Cost-effective: Single-phase inverters are generally cheaper than their three-phase counterparts.
- Simplicity: The technology is relatively simple and therefore low-maintenance.
Disadvantages:
- Power limit: The feed-in power to the public grid is limited to a maximum of 4.6 kW per phase. For larger systems, a three-phase inverter is required.
- Less flexibility: Single-phase systems are less flexible when distributing the generated electricity within a building.
Conclusion:
Single-phase inverters are a proven and cost-effective solution for smaller photovoltaic systems. They are ideal for homeowners looking to partially meet their electricity needs. However, for larger systems or specific requirements, three-phase inverters are more suitable.
