- Vendor: Solis
Specifications
Product Description
The Solis S5-GC30K Three-Phase 30kW On-Grid Solar Inverter is designed for commercial deployments seeking maximum energy and advanced control. With 3 MPPT and 6 total inputs, it manages different orientations and irradiance levels while maintaining a 98.6% efficiency (EU 98.2%). It integrates string monitoring and I-V curve analysis for rapid diagnostics, supports nighttime PID recovery (optional), and allows export control. The IP66 enclosure and intelligent redundant fans ensure safe and stable operation in demanding outdoor environments.
Main Features
- 3 MPPT / 6 strings, ideal for two or three roof sections with different behaviors.
- Max. efficiency 98.6% and low distortion (THDi < 3%) for superior power quality.
- MPPT range 200–1000 V, startup at 180 V, UDC max. 1100 V for long strings.
- 16 A per string (Isc 20 A) and 32 A per MPPT: compatible with TOPCon/HJT modules.
- DC/AC up to 150%, higher plant factor and annual production.
- RS485 communications and Wi-Fi/GPRS option with SolisCloud for remote O&M.
Advantages or Benefits
- More energy due to its high efficiency and the possibility to oversize the photovoltaic field.
- Intelligent O&M with I-V scanning and string alarms that reduce diagnostic times.
- Flexible design for complex rooftops without compromising performance due to high currents.
- Advanced safety: AFCI, SPD Type II on DC/AC, anti-islanding, and thermal control.
- Professional installation with MC4 on DC, OT terminal on AC, and LCD for commissioning.
Purpose or Applications
Focused on three-phase self-consumption of 30 kW in warehouses, hotels, logistics, agro-industry, and public buildings. Perfect when export limitation or precise monitoring of a large number of modules by string is required.
