Monitor the Input Power/Accumulated Power of the Inverter

 How to know the input power to the inverter?
Q
 How to know the accumulated input power of the inverter?
A Input power monitor [d014]
 Displays the input power (instantaneous value) of the inverter.
Code
[d014] Input power monitor
A Accumulated input power monitor [d015]
 Displays the accumulated input power of the inverter.
 The gain of the displayed content can be converted using the "Display gain for the accumulated
input power monitor [b079]".
Displayed value of [d015] = [Actual accumulated power (kWh)] / "Display gain for the
accumulated input power monitor [b079]"
(Example) When [b079] is 100 and the value of [d015] is 1000, the accumulated power is
100,000 (kWh).
 This monitor value is stored in the internal memory of the inverter when the power is shut off.
The data can be cleared by one of the following:
- By changing the "Accumulated input power monitor clear [b078]" to 01 and pressing the
[SET] key of the keypad, [d015] can be cleared to 0.
- By assigning "Accumulation input power clear [KHC] (53)" to the input terminal and
turning on that terminal, [d015] can be cleared to 0.
