Solis 30kW S5 3 Phase Triple MPPT - DC

Solis 30 kW S5 3-Phase Triple MPPT – DC Inverter

Overview
The Solis 30 kW S5 series three-phase grid-tie inverter is designed for commercial and larger residential solar installations that require high output, high flexibility in string design, and robust protection features. Thanks to its 3 independent MPPT inputs, wide DC input voltage range, and IP66-rated weather‐resistant housing, it’s ideal for system designs with multiple string orientations, partial shading, or oversized DC arrays.

Key Features & Specifications

• Rated AC output power: 30 kW with short-term capacity up to 33 kW. 

• Triple MPPT architecture (3 independent MPPTs) for improved yield when strings have different orientations/tilts/shading.
  
  Maximum conversion efficiency around 98.5%. 

• Ultra-low start-up DC voltage (~180 V) and high maximum DC input voltage (~1,100 V) for long strings and modern high‐voltage PV modules.

• String current capability: e.g., 32 A input per MPPT, 16 A per PV string (depending on configuration)

• Built-in safety & protection features:

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

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

  • Reverse polarity protection on the DC side. 

• Ingress rating: IP66, making the unit suitable for outdoor installations and harsh environments. 

• Monitoring & control: Supports string-level monitoring, smart I-V curve diagnosis, remote firmware upgrades via SolisCloud. 

• Warranty: Standard 5-year warranty with extension options available (10 or 20 years) in many markets.

• Local compliance: Certified for South African grid standards (e.g., NRS 097-2-1). 

Applications & Benefits

• Applications: Ideal for commercial rooftop solar systems, light industrial three-phase power installations, large residential estates using three-phase supply.

• Benefits:

  • The triple MPPT input gives you flexibility in array design: you can handle modules on different roof aspects or with varied shading and still keep each MPPT optimised.

  • High DC input voltage capability and low start voltage let you use longer strings, reduce cable runs, and handle modern high-voltage panels — lowering BOS (balance of system) cost.

  • High efficiency and strong protection features mean higher energy yield and safer operation — important for commercial installations where downtime or faults are costly.

  • Rugged outdoor-rated design (IP66) and good monitoring features support long-term reliability and easier maintenance.
