Hi there.
I have unused car battery Centra Futura CA472 47Ah / 450A and solar panel with this data on label:
SLVE_01
Company: FirstSolar.com
Nominal Power 72,5W +/- 5%
Current at mpp 1,09A
Voltage at mpp 66,6V
Short circuit voltage 1,23A
Open circuit voltage 88,7V
Max system voltage 600V UL / 1000V
Max source circuit fuse 2A UL/IEC61730 10A
Protection class 2
Cell type CdTe
Fire rating Class C
This accumulator will be power supply for private property gatewey wireless opener that i have already made with ATmega 328p, nrf24l01 data transfer modules, some other parts and servomotors with 12V motors to open the gate door. Everything works fine but nearless power source is lke 200 meters away so idea is to use this parts. What dou You think?
Can you help me to find power regulator fot this circuit from this shop:

I try to find something cheap but i don't realy know how to read this parameters from solar panel.
On allegro there are a lot of cheap regulators but description says something like "maximum circuit voltage max 50V" so my panel have to high voltage for them?
