Technical specifications

Ratings refer to the linked document revision. Confirm the nameplate, motor current and operating conditions for the exact selection.

Supply

DC input — 220 V class
July 2024 manual: 200–450 VDC; maximum open-circuit voltage (Voc) 450 V.
PDF p. 6
DC input — 380 V class
350–800 VDC; maximum Voc 800 V.
PDF p. 6
Recommended Vmpp
220 V class: 250–400 V, recommended point 305 V. 380 V class: 450–600 V, recommended point 530 V.
PDF p. 6
Operation versus standby
P23.02 allowing a threshold down to 160 V does not establish 160 V as the normal operating input limit for the 220 V class.
PDF p. 49

Output and load capacity

1/3-phase 220 VAC for the 220 V class; 3-phase 380–480 VAC for the 380 V class.
PDF p. 6
Output frequency
50/60 Hz applications; the manual lists a 600 Hz maximum. The motor's permissible speed must be checked separately.
PDF p. 6
Overload
150% of rated output current for 1 minute.
PDF p. 6

Motor and process control

MPPT
The July 2024 user manual specifies MPPT efficiency above 99%.
PDF p. 6
MPPT + PID
The brochure specifies combined MPPT and PID control.
PDF p. 6
Water/light conditions
Sleep at high water level or weak light; wake-up at low water level or sufficient sunlight.
PDF p. 6
Operator panel
LED keypad is standard; LCD keypad is optional.
PDF p. 5

Communication and options

Remote monitoring
GPRS monitoring is optional; the module has separate connection and operating documentation.
PDF p. 6

Commissioning and operation

AC/DC changeover
The AC/DC switching-board solution is described in Appendix A; board and external-circuit selection belong to the installation design.
PDF p. 74
Long motor cable
For motor cables longer than 100 m, evaluate an output reactor, dV/dt filter or sine-wave filter.
PDF p. 10
Commissioning checks
Check PV Vmp/Voc, motor power/current, cable length, motor insulation and fault records together.
PDF p. 18

Protection functions

Enclosure protection
The manual states IP20/IP21; confirm the enclosure class for the exact ordered model.
PDF p. 6

Operating environment

Operating temperature
−10…+50 °C; derating is required above +40 °C.
PDF p. 6
Altitude
Above 1000 m, the manual specifies 1% derating per additional 100 m.
PDF p. 6
Cooling
Air-cooled construction.
PDF p. 6

Selection information

PV array and motor selection
The manual recommends PV power around 1.5 times pump power as a design guideline, not a universal guarantee. Total Voc must stay below the maximum.
PDF p. 6

Model and dimension tables

Check the units and document revision in each table. Wide tables can be scrolled horizontally on small screens.
