Dear reader,
For an esp8266 project I have a question and I hope one of you can help me I want to use this SZBK07 300W 20A Buck module ( see below) on a 72Cell 300Watt solar panels with a Open voltage Voc of 43V. This module is rated 40V input max. That is just outside the absolute maximum ratings of the TL8711. This TL8711 seem to be, but is not for sure , the 20Pin control chip at the back of the module. Can any one of you tell me if this control chip is fed directly from this input or is there a regulator in between the input voltage and the control chip Vcc. These are my questions:
Does any one have experience with this module?
Is the control chip a TL8711?
Can I use this module for this panel with a Voc of 43 Volt ?.
Thanks for the help
