Energy Output Deviation Adjustment
Energy output deviation adjustment is useful when the total power output displayed in LCD
(E-total) is different from the reading value of the external power measuring device.
(Energy-adj value)= (Real measured value)-(E-tot reading value).
step 1 Tap “Function” from the default menu;
step 2 Tap “Set-parameter”;
step 3 Tap “Sys-parameter” after entering the correct password;
step 4 Tap “E-total adjust” and enter into the energy output deviation adjustment sub-menu;
Tap the cell below the “Compensation” and the keypad appears. Enter the energy
compensation by tapping the keypad;
step 5 Tap “Enter” to confirm the setting.

Checking Running Information
Running information contains all data related to the operation of the MV Station:
Real-time Data
The real time running information of the inverter can be checked.
The output power, DC voltage & current, power factor, reactive power, efficiency, daily/
monthly/annual power yields, internal temperature, positive/negative insulation resistance to
the ground, running time, amount of CO
2
reduction, grid frequency, AC phase/line voltage,
inverter temperature, AC & DC switches states, bypass switches/fuse state, power supply
mode are included.
Power Curve
The output power curve shows the power yield on that particular day in percentage of the
nominal power. The data is updated every several seconds and all the diagram data will be
cleared at the beginning of a new day.
E-histogram
The histogram shows the power yields of the present day.
Proceed as follow to view the running information:
step 1 Tap “Function” from the default menu.
step 2 Tap “Run-information” and switch among “Real Time Data”, “Power curve” and “E-
histogram”. The default display is “Real Time Data”.
step 3 Tap “Power curve” and enter into the power curve sub-menu.
step 4 Tap “E-histogram” and enter into the electricity histogram sub-menu.
