Solis Solis S5-GR3P
Professional solar installations demand reliable three-phase inverters that maximize energy conversion while withstanding harsh environmental conditions. This Chinese-manufactured grid-tied inverter delivers exceptional performance with its impressive 98.7% maximum efficiency rating, ensuring minimal power loss during the conversion process.
Engineered for commercial and industrial applications, this robust unit features dual MPPT channels for optimal solar array management and maintains clean power output with just 2% total harmonic distortion. Despite its powerful capabilities, the inverter maintains a compact profile at 16.5 kg, making installation straightforward for technicians. The IP66 protection rating provides complete dust protection and resistance to powerful water jets, ensuring reliable operation in challenging outdoor environments where consistent three-phase power generation is critical.

Frequently asked questions
Is the Solis S5-GR3P single-phase or three-phase?
The Solis S5-GR3P is a three-phase grid-tied inverter, so it needs a three-phase supply and cannot be connected to an ordinary single-phase domestic service. Spreading generation across three phases keeps the load balanced, which is why network operators usually allow more capacity on a three-phase connection than on a single-phase one.
How efficient is the Solis S5-GR3P?
The Solis S5-GR3P is rated at 98.7 percent maximum efficiency, a strong peak figure meaning barely over one percent of the DC energy reaching it is lost in conversion. Solis does not publish a European efficiency for the S5-GR3P, and that weighted number is the one that better predicts annual yield.
How many MPPT channels does the Solis S5-GR3P have?
The Solis S5-GR3P has two independent MPPT channels, so two groups of strings on different roof planes or with different shading can be tracked separately. Solis does not publish an MPPT voltage window or a maximum DC input current for the S5-GR3P, both of which are needed before strings can be sized.
What does the 2 percent THD of the Solis S5-GR3P mean?
Total harmonic distortion of the Solis S5-GR3P is quoted at 2 percent, meaning the current it injects is a close match to a clean sine wave. Low distortion matters on a three-phase commercial connection, where several inverters may run in parallel and their harmonics add up at the point of coupling.
Can the Solis S5-GR3P be mounted outdoors?
The Solis S5-GR3P carries an IP66 rating, so outdoor wall mounting is within its declared sealing level, including exposure to driving rain and dust. At 16.5 kg it is a one-person lift onto its bracket for most installers. Solis does not publish an operating temperature range, worth checking before siting it in full sun.
