SolarEdge SE33.3K-RW00IBNM4 String Inverter 33.3 kW Three-Phase
The SolarEdge SE33.3K-RW00IBNM4 is a three-phase string inverter of 33.3 kW for commercial systems, designed to work with SolarEdge power optimizers: maximum power point tracking is performed module by module, while the inverter works at a fixed string voltage in the 680-1,000 V DC range and accepts up to 58,275 W of photovoltaic power.
It integrates as standard the field-replaceable Type II DC surge protection, configuration via SetApp (without display) and monitoring at single-module level. Maximum efficiency is 98.3 % with a weighted European efficiency of 98 % and night-time consumption below 4 W. IP65 enclosure, user-replaceable fan cooling, temperature from -40 to +60 °C. Compliant with CEI 0-21 and CEI 0-16, with a warranty from 12 to 20 years.
