WattKit Pre-assambled AC box 16A-T2

WattKit Pre-Assembled AC Box with T2 Surge Protection

The WattKit pre-assembled AC box is a complete, ready-to-install electrical distribution solution for solar power systems , available in multiple current ratings (16A, 20A, 25A, 32A). The box includes the necessary protective components and switches, significantly simplifying installation while ensuring the system’s safe operation.

Pre-assembled design – faster installation

One of the biggest advantages of the WattKit AC box is that it arrives pre-assembled, eliminating the need to assemble components separately. This significantly reduces installation time and minimizes the risk of errors.

For installers, this provides a fast, standardized, and reliable solution for the AC-side design of solar power systems.

Built-in protection – T2 surge protection and circuit breakers

The box contains the necessary protective devices, including a T2-type surge arrester, which protects the system in the event of a lightning strike or power grid surge.

In addition, miniature circuit breakers and a sectioning switch have been installed to ensure system isolability and protection against faults.

Multiple current ratings – flexible system adaptation

The product is available in several versions:

• 16 A – for smaller systems
• 20 A – for general residential use
• 25 A – for larger inverters
• 32 A – for higher-power systems

This allows the box to be precisely matched to the power output and configuration of the specific solar system.

Stable electrical parameters and industrial reliability

The system is designed for a nominal voltage of 3×400 V and provides short-circuit withstand capacity of up to 6 kA. Support for the TN-S grounding system ensures compatibility with modern electrical networks.

The design complies with relevant electrical standards, making it safe for use in residential and small industrial systems.

Outdoor installation and robust design

The AC box has an IP55 rating, making it resistant to dust and moisture and suitable for outdoor installation. The wide operating temperature range (−25°C – +60°C) ensures stable operation under various environmental conditions.

The robust housing and fixed installation guarantee long-term reliability.

What is the difference between the 16 / 20 / 25 / 32 A versions?

The main difference between the various models is the rated current, which determines the system capacity for which a given model is recommended.

The 16A and 20A versions are ideal for smaller residential systems, while the 25A and 32A versions are recommended for larger inverters and higher-capacity systems. The models are identical in function and construction; only the load capacity differs.
