Hi everyone, sorry for the noobish questions but I’ve been trying to figure this out all day and I need help.
I have a 1.5W 5V (USB) load I want to power with a battery and have the battery recharge off of solar power.
Requirements:
• 2 x Solar panels (aesthetics) ,
• Ideally enough lipol battery to last for 24 hours of contant operation (in the event there is no sun)
• I need to keep the parts as cheap as possible. As this will be produced in high quantities.
Parts I have laying around thank might be useful (ignore if this is the wrong starting voltage:
• Already have 2x 12v 1.5w panels
• 12V 3000mah lipol battery
• 2V - 24V To 5V 9V 12V 28V MT3608 DC-DC Boost Module 2A Adjustable Step Up Module Boost Converter Power Supply Module
I’ve never really worked with solar and battery recharging It seems like every part I find outputs the wrong voltages for my application.
There has got to be a simple solution here without having to throw step up and step-down modules in the loop.
Questions:
• If I’m using two solar panels in parallel do I need to add some sort of diodes to stop them from back feeding each other?
• I was looking at this part https://www.banggood.com/5V-2A-Solar-Panel-Power-Bank-USB-Charge-Voltage-Controller-Regulator-Module-6V-20V-Input-p-1099540.html?gmcCountry=US¤cy=USD&createTmp=1&utm_source=googleshopping&utm_medium=cpc_bgs&utm_content=frank&utm_campaign=pla-all2-us-pc&gclid=Cj0KCQiAtP_iBRDGARIsAEWJA8gv7jFdlLQEhNNZQ3IlqADMzDZ4vgypSrIBJpDkoaahc6PeP27bi3saAjmqEALw_wcB&cur_warehouse=CN
o (can take 6-20v IN and turn its into 5v) what battery to use?
Anyone who could help point me in the right direction and maybe provide some part numbers would be greatly appreciated!
