This overview compares EMITER Switchgear IP65 hermetic DCAC with Dehn 1000V type 2 DC surge arrester for 1 PV string and 1 MPPT, AC Dehn type 2, 16A 3-phase with alternative models from the same manufacturer: EMITER EM-41_DCAC, EMITER EM-215N_DCAC, EMITER EM-215_DCAC, EMITER EM-75N_DCAC, and EMITER EM-1358N_DCAC. All units feature hermetic IP65 enclosures designed for photovoltaic installations supporting 1 PV string and 1 MPPT. The primary distinctions lie in the AC connection parameters (single-phase vs. three-phase, current ratings from 10A to 20A) and the specific surge protection components used (Dehn or Noark brands, type 2 or combined type 1+2).
⚙️ Below is a specification comparison covering enclosure ratings, solar configuration support, DC and AC surge protection brands and types, and AC connection parameters.
