subcategory
grid-tied PV string inverter (utility-scale, 1500 Vdc, no battery interface)
topology
transformerless (no galvanic isolation)
variant_note
Shares the 1136*870*361 mm / <=116 kg chassis and the 12-MPPT DC architecture with SG320HX and SG350HX. Unlike those two, the fetched SG285HX datasheet gives a single AC rating at 40 C rather than a three-point temperature derating curve.
