SolarEdge Three Phase 33300W Inverter for 277/480V Grid SE33.3KUS

The SolarEdge HD Wave inverters use a unique power conversion technology that is based on a distributed switching and powerful DSP processing platform. HD-Wave technology is able to synthesize a clean sine wave that leads to a dramatic reduction in the magnetics and heavy cooling elements. Because MPPT and voltage management are handled separately for each module by the power optimizer, the inverter is only responsible for DC to AC inversion. Consequently, it is a less complicated, more cost effective, more reliable solar inverter with a standard 12 year warranty, extendable to 20 or 25 years. The fixed string voltage ensures operation at the highest efficiency at all times independent of string length and temperature.

This small and lightweight inverter enables simplified shipping, storing and one-person installation. The record-breaking efficiency allows more energy production for residential grid-tie solar systems. The SE33.3KUS is UL1741, UL1699B, certified inverters with ground-fault isolation detection and interruption compliance.
