3. THE BLUEPLANET INVERTER OVERVIEW
Full digital control using digital signal processing (DSP)
The KACO XP uses two DSPs to control the inverter and an ARM processor for user and external interface.
These full digital control schemes offer enhanced reliability, accuracy, efficiency, flexibility and convenience.
High reliability
The KACO Inverter features built in reliability with redundant power supplies, highly efficient cooling of critical
components and intelligent cooling fans. The fans are monitored and controlled according to load and
environmental temperature conditions. All components used in the KACO XP are designed for industrial use.
The IGBT stack was designed based on the IEEE WG PEBB TF2 standards. These standards mandate the
use of laminated DC bus-bars that provide for very low stray inductance and gate drive interfacing with
differential signaling. This feature enhances reliability and ease of maintenance. Full digital control
technology of the XP also enhances reliability by reducing component count compared to traditional analog
electronics.
Powerful human interface and networking
The Inverter’ features a powerful and friendly Graphic User Interface (GUI). The “all-in-one” design for the
GUI provides for more convenient operation and monitoring. The GUI is a big, easy to use display with color
TFT LCD (480 x 272 dots) and provides detailed operating information in different languages. RS232,
RS485, and Ethernet interfaces for networking are standard in the Inverter.
System flexibility
The Inverter provides 4 analog inputs, an S0 input, 1 programmable dry contact output A type (Normally
open) and B type (Normally closed), and 1 digital input. The analog inputs are preconfigured for the user and
allow easy connection of temperature sensors and a reference cell. The S0 input is preconfigured for smart
metering.

To get the most accurate data from the analog interface, the user must calculate gain and offset. Then the
user must change the parameters of the Inverter. The symbols for gain and offset are listed here:
Ml: lower limit of analog input by sensor.
Mu: upper limit of analog input by sensor.
Dl: lower limit of displayed value.
Du: upper limit of displayed value.
M: input value in range of Ml and Mu.
D: displayed value in range of Dl and Du.
Gain: G= (Du –D1) / (Mu – M1)
Offset: O = D1 – (G x M1)
Displayed value: D = (G x M) + O
After calculating gain and offset, the user must change the values through the GUI or use the CMT (change
the settings in the analog tab located in parameter panel).
CAUTION!
Voltages > 10Vdc or reversed polarity may lead to damage of the sensor input circuits
IMPORTANT!
System will show unexpected values if gain and offset are not properly set. Ensure that
calculations are exact.

IMPORTANT!
The inverter can’t be started when a fault is present. Use the ‘fault reset’ procedure and
retry the start operation. Refer to the ‘Fault & Warning’ section for a description of the ‘fault
reset’ procedure.
If the GUI gives a Code F16 or 'Inv. Phase Order' failure message, the phase rotation is
reversed. Shut down the system, power off all AC and DC voltage to the inverter, and
reverse the phase A and B connections on the AC field wiring terminals.
CAUTION!
If the fault isn`t resolved after ‘fault reset’ procedure is complete, contact the KACO technical dept. at +1
(415) 931-2046
Operating State
The Inverter has eight operating states. The explanations about each state are below.
Disconnected (default): Before operation has commenced the inverter is in the disconnected state. In
this state, the inverter is totally isolated from the PV array and the utility grid.
Connecting to the PV array: When the inverter is in the "Disconnect" state, the ‘Inverter On’ button on
the GUI is selected and the PV voltage is kept above 200V for 5 seconds, the system turns on the PV Array
side contactor (PV_MC). In this state, if the PV voltage falls below 100V, the inverter returns to the
Disconnect state.
Connecting to Grid: When the inverter is in the “Connecting to PV Array" state and the PV voltage is kept
above the value of “MPPT V Start” parameter during the time set by “MPPT T start” parameter, the contactor
on the grid side is turned on. The inverter keeps this state for 8 seconds.
Initializing MPP: The inverter calculates the MPPT start voltage which is product of measurement of PV
voltage and the parameter “MPP Factor”. After 5 seconds, the inverter system enters into the "MPP start"
state.
MPP start: In this state, the inverter controls the PV voltage. Reference of the PV voltage (“V
dc
reference”
parameter) the inverter changes from “open circuit” voltage to the value of the “MPPT V start” parameter.
GUI during proper operation
Page 52
MPPT: If the PV voltage approximates the MPP start voltage (value of “MPPT V Start” parameter), the
MPPT will start. The inverter follows the MPP target value automatically, which is varied by irradiance values.
If the MPP target value is out of the allowable MPPT range ([MPP start voltage – MPP Range lower] ~ [MPP
start voltage + MPP range upper]), the system will return to the “Initializing MPP” state and will recalculate
the MPPT start voltage.
System stop: When the “OFF” button in the GUI is selected, the PV Array side contactor and the Grid side
contactor are turned off and the system stops. If the output power of inverter is kept below value of “MPPT P
stop” parameter during time of “MPPT T stop” parameter, connection to the grid is terminated. In addition, If
PV voltage is below 100V, the inverter stops.
Fault: If a fault occurs during operation, the system stops. The system resets the fault and tries to remove
the fault. In the case that system removes a fault successfully, system restarts all by itself. The system
allows three auto fault resets within 30 minutes. After three attempts, the system will log an error and the
system will not try to restart.
