What happens if we do not set the right time in Inverter?

The inverter has various functions depending on the Time of Inverter. For example, it reset Daily Energy and runtime every day at 12:00 AM.

If you do not set the right time you might see Daily Energy getting reset during daytime (when inverter time is 12:00 AM)

Which parameters are affected by wrong Inverter time?

  • Daily Energy
  • Daily Runtime
  • Daily Revenue
  • Daily Imax (maximum current)
  • Daily Pmax (maximum active power)
  • Daily Qmax (maximum reactive power)
  • Daily Qmin (minimum reactive power)
  • Maximum/minimum isolation resistances

Which parameters are affected by wrong Inverter date?

  • Monthly Energy
  • Yearly Energy
