I need to switch this relay G2R-1-E Datasheet, PCB Relay. , THT, 5 VDC, 16A.
How should i wire it? Using transistor or optocoupler?
I have currently available:
• Transistor BC 546B
• Optocoupler ILD74
• several resistors and so on.
It will be used to disconnect the solar input line from the solar generator. If its cloudy/low light, the batterie turns on but uses more energie then it harvests.
