Specifications Breakdown
Power Output & Efficiency
The GoodWe GW5000-EH delivers 5.0 kW AC output at 97% CEC efficiency (97.8% peak), while the GoodWe GW10K-ET delivers 10.0 kW at 97.5% CEC (98% peak). The 5000W power difference is substantial and determines the maximum solar array each inverter can handle. The GoodWe GW10K-ET's higher CEC efficiency means it converts 0.5 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 60 kWh more usable energy per year, worth roughly $9 at $0.15/kWh.
MPPT Trackers & Panel Configuration
The GoodWe GW5000-EH features 2 MPPT inputs while the GoodWe GW10K-ET has 2. Matched MPPT counts provide equal flexibility for panel string configuration. Both can independently optimize 2 separate panel groups. The GoodWe GW5000-EH accepts up to 600V DC input with a 80-550V operating range, versus 1000V DC and 150-850V for the GoodWe GW10K-ET.
Monitoring & Communication
The GoodWe GW5000-EH includes GoodWe SEMS Portal (WiFi/Ethernet) monitoring with WiFi / Ethernet / RS-485 communication, while the GoodWe GW10K-ET offers GoodWe SEMS Portal (WiFi/Ethernet) via WiFi / Ethernet / RS-485. Both use comparable monitoring platforms. 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 GoodWe GW5000-EH comes with a 10-year warranty while the GoodWe GW10K-ET 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.
