Solis S5-GR3P

Name: Solis S5-GR3P
Brand: Solis

Grid-tied inverter, three-phase, 3-20 kW

TypeOn-grid

Phases3-phase

AC power3-20 kW

Efficiency98.7%

ProtectionIP66

Three-phase grid-tied Solis S5-GR3P inverters in twelve models rated 3-20 kW, for residential and business installations. They reach up to 98.7% maximum efficiency and allow more than 150% DC/AC oversizing of the PV array, while two MPP trackers (160-1000 V) make string sizing easy. AFCI arc-fault protection actively reduces fire risk, the IP66 enclosure allows outdoor mounting, and the system supports weak grids and export power control. You can track operation remotely in SolisCloud.
