Wireless remote to switch charge controller output using MODBUS Also switches daily using EPEVER RTC Code has only been tested on an XTRA Series. EPever MPPT Charge controller RS485 Interface
- Design brief:
- Use: Scottish Bothy with multiple occupants. Operation must be simple:
-
* 'Press Here' > 'Lights ON' Press Again > 'Lights OFF' -
* Remote Load ON/OFF switching to eliminate trip in dark to Epever controller - Lights have been left on for weeks battening the flattery:
-
Daily Load OFF timed by EPever RTC - IF ON > OFF at Midday 12:00hrs - Power consumption: <1mA@12Volts
