## Summary description

This DC+AC switchgear is designed for photovoltaic systems, featuring a Type 2 surge protective device for 1000V DC circuits. It supports 1 PV string and 1 MPPT input. The AC section includes a 3-phase 25A protection system with a 100mA 40A residual current device. This unit ensures reliable electrical safety and surge protection for solar installations, providing a compact and integrated solution for effective energy management and equipment longevity.

## Long description

This DC+AC switchgear is a comprehensive protection solution engineered specifically for photovoltaic installations. It integrates essential safety components into a single, compact enclosure, designed to manage 1 PV string with 1 MPPT input. The system provides robust protection for 1000V DC circuits and includes a dedicated 3-phase 25A AC protection circuit, ensuring that both the solar array and the grid-connected equipment are shielded from electrical faults and voltage spikes.
Advantages
The primary benefit of this unit is its integrated design, which significantly simplifies the installation process by combining DC and AC protection in one housing. The inclusion of a Type 2 surge protective device offers critical defense against transient overvoltages, which helps extend the operational lifespan of solar inverters and other sensitive components. Furthermore, the 3-phase 25A AC protection combined with a 100mA 40A residual current device provides reliable safety against short circuits and leakage currents, meeting standard electrical safety requirements for residential and small commercial solar systems.
Suitable for
Residential photovoltaic systems with a single string configuration
Small-scale commercial solar installations requiring 1 MPPT input
Systems operating at 1000V DC voltage levels
Installations requiring integrated 3-phase AC grid protection
When it may not be suitable
This switchgear is not designed for systems utilizing multiple PV strings or complex multi-MPPT inverter configurations. It is also unsuitable for high-voltage industrial solar arrays that exceed the 1000V DC rating or for single-phase AC grid connections.
Key specifications
Maximum DC voltage: 1000V
Input capacity: 1 PV string, 1 MPPT
Surge protection: Type 2
AC protection: 3-phase 25A
Residual current device: 100mA 40A
How to use
The switchgear should be mounted in a dry, accessible location between the solar inverter and the AC distribution board. Installation must be performed by a qualified electrician in accordance with local electrical codes. The PV string cables are connected to the DC input terminals, while the AC output is wired to the 3-phase grid connection. Ensure all connections are tightened to the specified torque to prevent overheating and maintain electrical integrity.
What to consider before purchase
Verify that your inverter supports a single MPPT input
Confirm that your solar array voltage does not exceed 1000V DC
Check that your grid connection is 3-phase
Ensure the enclosure dimensions fit your intended installation space
Usage recommendations: Regularly inspect the surge protective device status indicators to ensure they remain in the operational state. If a surge event occurs, check the device for signs of damage and replace the internal modules if the indicator has changed color.
