comma missing in output of QPIGS for inverter_heat_sink_temperature?

[joerghohn]

Hi,

the QPIGS query shows a inverter_heat_sink_temperature of ~550 to 650°C
Shouldn't that be 55.0 to 65.0°C?

Interesting - my inverter gives it as a direct temp

what is your inverter model number / type?

[joerghohn]

Sorry, missed your question.
It is this inverter: https://www.amazon.de/dp/B07YL3VVQ2/ref=pe_3044161_185740101_TE_item
Seems to be china made, distributed under different brand names. Documentation can be found here: https://voltaconsolar.com/media/wysiwyg/Axpert_MKS_PF1_-MKS_1-5KVA_manual-20170804.pdf
