Solis 25kW S5 3 Phase Triple MPPT - DC

Solis 25 kW S5 3-Phase Triple MPPT – DC Inverter

Overview
The Solis 25 kW S5 3-Phase Triple MPPT inverter is a high-performance grid-tie solution designed for three-phase solar installations that demand flexibility, high yield and reliability. With three independent MPPT channels, a wide DC input voltage range and a rugged IP66-rated enclosure, this inverter is ideal for commercial rooftops, industrial setups or large residential three-phase sites.

Key Features & Specifications

• Rated AC output power: ~ 25 kW (with surge capacity up to ~27.5 kW) 

• Triple MPPT design (3 independent Maximum Power Point Trackers) — allows string groups to face different orientations/tilts, reducing mismatch. 

• High conversion efficiency: up to ~ 98.5% maximum efficiency.

• Wide DC input voltage range: ultra-low start-up voltage ~180 V and maximum input up to ~1,100 V DC. 

• String current and input capability: For example 32 A input per MPPT, 16 A per PV string. 

• Built-in safety & protection features:

  • Type-II surge protection on both DC and AC sides. 

  • Integrated AFCI (arc-fault circuit interruption) on DC side.

  • DC reverse polarity protection. 

• Robust build: IP66 rating for outdoor exposure

• Monitoring & Smart features: Supports string-level I-V curve diagnosis, remote monitoring (via WiFi/RS485 etc) and registration in SolisCloud. 

• Warranty: Standard 5 years, with options to extend (in many markets) to 10 or 20 years. 

• Grid code / local certifications: Certified for South African grid (e.g., NRS 097-2-1) when sold locally. 

Applications & Benefits

Applications:

• Three-phase commercial rooftop solar systems (office blocks, warehouses, retail).

• Light industrial sites where three-phase supply is available.

• Large residential estates with three-phase supply and multiple string orientations.

Benefits:

• The triple MPPT architecture gives you real flexibility: if parts of the array face different directions or have varying shading, each MPPT can adapt separately, so you get better yields.

• High efficiency means more of your solar energy is converted to usable AC power, increasing return-on-investment.

• The wide DC input range allows use of modern high-voltage panels, longer strings (fewer combiner boxes), and potentially lower cable losses.

• The rugged outdoor rating (IP66) means less worry about harsh weather, dust, or exposure — good for rooftops or semi-outside installations.

• Strong safety/protection features reduce risk, making it more appealing to customers and installers alike.

• It’s “future-ready”: remote monitoring, export power control (where required), and compatibility with modern string monitoring practices.
