EMITER Switchgear Attached DCAC Hermetic IP65 with Dehn 1000V Type 2 DC Surge Arrester, 1 x PV String, 1 x MPPT // og. AC Dehn Type 2, 20A 3-Phase

For solar installations where space is tight and protection is non-negotiable, this EMITER DCAC switchgear combines DC and AC surge protection in a single hermetic IP65 enclosure. Unlike separate boxes for each side, it integrates a Dehn 1000V Type 2 DC surge arrester for one PV string and one MPPT input with a Dehn Type 2 AC surge arrester rated at 20A for three-phase systems. The result is a compact, wall-mountable unit that keeps critical connections safe from overvoltage and environmental stress without the clutter of multiple enclosures.

Highlights

• Hermetic IP65 polycarbonate enclosure protects against dust and water jets
• Dehn Type 2 DC surge protection up to 1000V for one PV string
• Dehn Type 2 AC surge protection for 20A three-phase circuits
• Integrated DC disconnect switch and AC breaker for safe maintenance
• Supports one MPPT input, ideal for single-string residential or small commercial systems
• Wall-mount design with screw terminals for secure, straightforward wiring

In daily use

Installation is straightforward: mount the box near the inverter, connect the single PV string to the DC input, and wire the AC side to the three-phase grid. The screw terminals accept standard solar cable sizes, and the hermetic seal means no additional weatherproofing is needed. During operation, the Dehn arresters clamp transient overvoltages on both DC and AC lines, while the disconnect switches allow safe isolation for servicing. The polycarbonate housing resists UV and impact, maintaining its integrity over years of exposure.
