Solis S5-GC

Name: Solis S5-GC
Brand: Solis

Commercial grid-tied inverter, three-phase, 25-50 kW

AC power25-50 kW

Phases3-phase

MPPT3 / 4

Efficiency98.8%

ProtectionIP66

Three-phase string inverters, Solis S5 series (S5-GC), rated 25-50 kW for commercial and industrial installations (C&I). A 3 or 4 MPPT design (200-1000 V range, 1100 V max input voltage) suits multi-facing roofs and allows long strings. AFCI 2.0 protection reduces fire risk, an IP66 enclosure with fan cooling enables outdoor mounting, and string monitoring with I-V curve scan simplifies servicing.
