Solis S5-GR3P(3-20)K Inverter from ONG Solar

Three-phase grid-tied solar inverter from Solis for commercial and industrial PV systems. Maximum efficiency 98.7%. Suitable for three-phase small and medium business facilities.

To select an S5-GR3P(3-20)K inverter, share your solar panel model, panel count and three-phase grid connection details. We will confirm the inverter version, string configuration and installation requirements. Request a price for your project.

Selection and system compatibility

Compare specific Solis S5-GR3P(3-20)K variants rather than treating the whole series as one inverter. MPPT and input availability affect how panels can be assigned to different roof areas. Roof slopes with different orientations require a string layout and verification of the electrical limits for the selected variant.

A grid-connected inverter must match both the PV array and the electrical connection. Check operating voltage ranges, permitted currents, string allocation and protection requirements. Ventilation and service access also matter. Power during a grid outage requires a separately designed backup system; having solar panels does not by itself ensure that loads remain supplied during an outage.

Enquire with ONG Solar

For an ONG Solar enquiry, prepare the exact panel model and quantity, string layout, grid parameters and inverter location. For replacement equipment, include the existing unit's nameplate. These details support checks of the selected variant and its associated components.
