64 w solar panel without a charge controller or battries but using a buck converter for direct regulated power?possible?
i shall start with explaining the situation.
i am going to be in the remote himalayas for about 2 months with a expedition team and for all our charging needs we are going to carry a few solar panels, most of them are small 5-15 watt ones .
the problem comes in when i introduced the 64 w thin film roll able panel.
the specifications for the panel are as follows
Rated Power 64 (Watts)
Rated Voltage 16.5 (Vmp)
Rated Current 3.9 (Imp)
Open Circuit Voltage 23.8 (Voc)
Short Circuit Current 4.8 (Isc)
i intend to use 3 LM2596 ebay buck converters to get 12 volts and 2 5V USB Output Converter DC 7V-24V To 5V 3A Step-Down Buck KIS3R33S Module KIS-3R33S for usb power.
All of these will have a common source of power (the solar panel) and have separate outputs as i need to charge multiple things at once.
will this setup work or i need to think of something else.?
