We tested a 10 kW Solar Inverter at full load yesterday as we tried to measure the power derating with an increase in temperature. The solar inverter ,
Power Inverter ,
Hybrid Inverter ,
Pure Sine Wave Inverter work for the solar system house hold .
What we expected to find : - The 10 kW inverter when given 10 kW DC input, would generate 9.9 kW of AC power at an ambient temperature of 25 deg C 
- This output power would stay constant for how many ever hours we run the test, given that the ambient temp. stays the same. - As we increase the ambient temp. from 25 to 45 deg C we expect that the heat sink continues to dissipate heat effectively and the power output is maintained at 9.9 kW. 
- Beyond 45 deg C the inverter would start to derate progressively as is mentioned by all inverter manufacturers. - At 55 deg C the power output would be limited to 50% - At 60 deg C the inverter would shut off.
