## Long description

The Doktorvolt Photovoltaic AC Distribution Board is a professional-grade electrical enclosure designed specifically for single-phase solar energy systems. This unit integrates high-quality Siemens components to ensure reliable performance, safety, and efficient management of electricity generated by photovoltaic installations. It provides a comprehensive protection solution, combining circuit breaking, switching, and surge suppression in a single, robust housing suitable for residential and commercial solar setups.
Advantages
The primary benefit of this distribution board is the inclusion of premium Siemens electrical components, which are renowned for their durability and precision. By integrating a C20A circuit breaker, a 25A switch, and a 300mA residual current device, the system offers multi-layered protection against overloads, short circuits, and leakage currents. Furthermore, the built-in T1+T2 surge protection device effectively shields sensitive solar inverters and household appliances from dangerous voltage spikes caused by atmospheric discharges or grid fluctuations, significantly extending the lifespan of the entire photovoltaic installation.
Suitable for
Single-phase residential photovoltaic systems
Small-scale commercial solar energy installations
Protection of solar inverters and grid-connected AC circuits
Upgrading existing solar power distribution setups
When it may not be suitable
This distribution board is designed exclusively for single-phase electrical systems and is not compatible with three-phase photovoltaic installations. Additionally, it may not be suitable for environments with extreme industrial interference or specific local electrical code requirements that mandate different protection thresholds.
Key specifications
System type: Single-phase AC
Circuit breaker: C20A
Switch rating: 25A
Residual current device sensitivity: 300mA
Surge protection class: T1+T2
Manufacturer: Siemens components
How to use
The distribution board should be installed by a qualified electrician in accordance with local electrical regulations. It is typically mounted between the solar inverter and the main building distribution board. Ensure that all cable connections are tightened to the specified torque settings and that the enclosure is properly grounded to allow the surge protection device to function correctly. Regular inspections should be performed to ensure the integrity of the connections and the status of the surge protection indicators.
What to consider before purchase
Verify that your solar installation is a single-phase system
Check if the 300mA RCD sensitivity meets your local safety standards
Ensure there is sufficient physical space for the enclosure installation
Confirm compatibility with your existing inverter output specifications
Usage recommendations
For optimal safety and performance, always ensure the distribution board is installed in a dry, accessible location protected from direct moisture. Periodically check the status window of the T1+T2 surge protection module to confirm it remains in an operational state.
