Solid product for outdoor solar projects
For MPPT PSU 5-24Vin 5V & 3V3 output (15W combined)
Good packaging, quick notification of the tracking number.
Just the tracking update of the greek post is absolutely horrible. Nothing the store can do about. So shipping 5/5.
The documentation could be more detailed.
E.G. the status LED of the LiPo charging IC. (Which is dual color for charging/charging finished)
The slide switch combined with the GND+SW contacts on the terminal block has 2 modes:
- One as extensions to the ON/OFF push-button on the board.
- The other as permanent ON via cable jumper, pull the cable jumper and the board goes OFF.
Board dimension: 100x87mm
Grid for the mounting holes: 94x81mm, 2.5mm screws.
Voltages on both ports are stable at 5.01V and 3.28V. (tested at low load)
The Vmpp potentiometer is not installed, so the board is currently set up for use with "normal" 12V solar panels (i.e. Vmpp 17-18V).
Potentiometer can be added later, SMD resistor with the default value must be removed.
Communication is great, the store responds within 2 days with helpful answers.
And for everybody else who also did not read the description - Vbat is a status pin with a voltage divider, so don't panic when the charged battery shows 3.3V. ;)
