Specifications Breakdown
Power Output & Efficiency
The Fronius Primo GEN24 5.0 Plus delivers 5.0 kW AC output at 97.3% CEC efficiency (97.8% peak), while the Sungrow SH10RT delivers 10.0 kW at 97% CEC (98.4% peak). The 5000W power difference is substantial and determines the maximum solar array each inverter can handle. The Fronius Primo GEN24 5.0 Plus's higher CEC efficiency means it converts 0.3 percentage points more DC solar energy into usable AC electricity. On an average 8 kW system producing 12,000 kWh annually, this efficiency gap translates to approximately 36 kWh more usable energy per year, worth roughly $5 at $0.15/kWh.
MPPT Trackers & Panel Configuration
The Fronius Primo GEN24 5.0 Plus features 2 MPPT inputs while the Sungrow SH10RT has 2. Matched MPPT counts provide equal flexibility for panel string configuration. Both can independently optimize 2 separate panel groups. The Fronius Primo GEN24 5.0 Plus accepts up to 600V DC input with a 80-530V operating range, versus 600V DC and 160-600V for the Sungrow SH10RT.
Monitoring & Communication
The Fronius Primo GEN24 5.0 Plus includes Fronius Solar.web (WiFi/Ethernet) monitoring with WiFi / Ethernet / Modbus TCP/RTU communication, while the Sungrow SH10RT offers iSolarCloud App (WiFi/Ethernet) via WiFi, RS485, Ethernet, CAN. Different monitoring ecosystems mean different mobile app experiences, data granularity, and integration options with third-party energy management systems. Reliable monitoring is essential for detecting production drops, identifying panel-level issues, and maximizing system uptime over the inverter's lifetime. Both carry IP65 protection ratings for equivalent environmental durability.
Warranty & Reliability
The Fronius Primo GEN24 5.0 Plus comes with a 10-year warranty while the Sungrow SH10RT offers 10 years. Matched warranty durations mean equal long-term manufacturer protection. Consider budgeting for a potential inverter replacement during the 25-30 year lifespan of your solar panels.
