DSH-00562-1.0-EN-US-2024-08-02 <br />1 Pairing PV modules with wattage above the limit may result in additional clipping losses. See the compatibility calculator at enphase.com/installers/microinverters/calculator. <br />2 Nominal voltage range can be extended beyond nominal if required by the utility. <br />3 Limits may vary. Refer to local requirements to define the number of microinverters per branch in your area. <br />IQ7HS Microinverter <br />INPUT DATA (DC)UNITS IQ7HS-66-M-US <br />Commonly used module pairings1 W 320–460 <br />Module compatibility —60-cell/120-half-cut-cell, 66-cell/132-half-cut-cell, and 72-cell/144-half-cut-cell PV modules <br />Maximum input DC voltage V 59 <br />Peak power tracking voltage V 38–43 <br />Operating range V 20–59 <br />Minimum/Maximum start voltage V 30/59 <br />Maximum input DC short-circuit current A 25 <br />Maximum module Isc A 20 <br />Overvoltage class DC port —II <br />DC port back-feed current A 0 <br />PV array configuration —1 × 1 ungrounded array; no additional DC side protection required; AC side protection requires <br />max. 20 A per branch circuit <br />OUTPUT DATA (AC) <br />Peak output power VA 384 @ 240 VAC, 369 @ 208 VAC <br />Maximum continuous output power VA 384 @ 240 VAC, 369 @ 208 VAC <br />Nominal (L-L) voltage/Range2 V 240/211–264, 208/183–229 <br />Maximum continuous output current —1.60 A (240 V), 1.77 A (208 V) <br />Nominal frequency Hz 60 <br />Extended frequency range Hz 47–68 <br />AC short-circuit fault current over three <br />cycles Arms 4.82 <br />Maximum units per 20 A (L-L) branch <br />circuit3 —10 (240 VAC), 9 (208 VAC) <br />Overvoltage class AC port —III <br />AC port back-feed current mA 18 <br />Power factor setting —1.0 <br />Power factor (adjustable)—0.85 leading ... 0.85 lagging <br />EFFICIENCY <br />CEC weighted efficiency %97.0 @ 240 V, 96.5 @ 208 V <br />MECHANICAL DATA <br />Ambient temperature range °C (°F)–40 to 60 (–40 to 140) <br />Relative humidity range %4 to 100 (condensing) <br />DC connector type —Stäubli MC4 <br />Dimensions (H × W × D)mm (in)212 (8.3) × 175 (6.9) × 30.2 (1.2) without bracket <br />Weight kg (lb)1.1 (2.4) <br />Cooling —Natural convection—no fans <br />Approved for wet locations —Yes <br />Pollution degree —PD3
