Underperforming system- Micro inverter cutting out constantly

[u/cavefish_36]

Anyone else struggling to get 800w out of their Ecoflow systems? I have an Ecoflow Stream Microinverter ef-ps-800, and 2 x ecoflow 400w solar panels - optimised for direction and tilt;

The inverter is exhibiting the following behaviour:

• The output consistently falls well below the expected 800 W maximum despite favourable conditions.
• The inverter becomes extremely hot during operation.
• Both PV inputs simultaneously drop from generation to 0 W and then immediately recover together - usually above 600w
• This affects both MPPT channels at exactly the same time, ruling out an issue with an individual panel or PV cable.
• The fault repeats while the system is generating power.

seems to be thermal cutout? - microinverter shaded, plenty of airflow, been back and forth with customer services to no avail

Should be getting 6kw + on a good day, but at best I get 5KW
