3.4 AC Wiring
The Sunmaster must be used in a permanent installation connected to a separate AC distribution group. Cabling must be double insulated. Use appropriate AC wire diameter to ensure single wire resistance does not exceed 0.25 Ohm (e.g., 3x4mm² for up to 25 meters).
3.5 Grounding
An equipment-grounding conductor must be connected to the AC-output ground terminal. Grounding must comply with local codes. The solar array does not require grounding due to galvanic isolation.
3.6 Specifications of the Solar System
The solar system must meet the following specifications:
- Maximum open circuit string voltage at lowest possible temperature of PV modules and maximum PV power connected to the inverter.
Solar System Specifications Table:
| Model Sunmaster | Max voltage | Max power |
|---|---|---|
| XS4300 | 550Vdc max | 4600Wp |
| XS3200 | 600Vdc max | 3500Wp |
| XS2000 | 450Vdc max | 2100Wp |
- Double insulated PV-wiring is required.
- All string cables must be double insulated and fitted with pre-assembled MultiContact connectors (Ø4mm).
- If two or more strings are connected, their lengths must be equal.
⚠️ CAUTION! Do not install the Sunmaster if the solar system does not comply with these stipulations.
3.7 DC Switch
A DC switch between PV modules and the inverter may be mandatory per local regulations (e.g., IEC60364-7-712). Mastervolt offers models with integrated DC switches. An external DC switch can also be used.
3.8 PV Modules and Strings
PV modules are connected in series to form a "string". String voltage should equal the open circuit voltage (Voc) per PV module multiplied by the number of modules per string. This value should be 70-95% of the calculated string voltage, depending on irradiation and temperature. The Sunmaster has a single MPP tracker and two parallel string connections (Figure 3-1).
3.8.1 Connection of two strings (standard)
Two strings can be connected directly to the Sunmaster's Solar inputs. The total input power should be distributed equally over both inputs as much as possible (Figure 3-2).
3.8.2 Connection of more than two strings (option)
For more than two strings, Multicontact Y-adapters may be used to combine strings (Figure 3-3, Figure 3-4). Strings connected to the same Solar input must have an equal number of identical PV-modules.
3.9 General Safety and Installation Precautions
- ⚠️ WARNING! Be sure that all wiring is disconnected from any power source during the entire installation.
- ⚠️ CAUTION! Short circuiting or reversing polarity may damage the Sunmaster, cabling, and terminal connections. Follow all installation instructions in order. The DC switch, if installed, must remain in the OFF position during installation.

5.3.6 Failures
The Sunmaster operates normally if the red ERROR LED is OFF. If the LED illuminates or blinks, a failure is detected. The display will show an error code (Figure 5-7). Refer to Chapter 6 for error code explanations. Normal shutdown occurs at night or with insufficient irradiation; this is not a failure.
5.3.7 Power Limitation
The power limitation function, if activated via a datalogger (e.g., DataControl Pro/Premium II), limits the inverter's output to a set percentage (e.g., "PM 80" means 80% of maximum power). The inverters return to normal operation after 10 minutes without a power limitation command.
5.3.8 3-Phase Block
This security measure, required by some grid operators for 3-phase configurations, ensures all inverters provide energy to the grid or none do. If one inverter fails, the others halt as well (Figure 5-8).
5.4 Maintenance
No specific maintenance is required. Examine the electrical installation annually for defects like loose connections or burnt wiring. Clean the cabinet with a soft, dry cloth only. Do not use liquids, acids, or scourers.

9 Italy Self Test
General
The Italy Self Test verifies the upper and lower limits of the AC voltage and AC frequency at which the inverter will disconnect from the grid. This test is performed by selecting the "System/Model" menu and, if the model is ITALY, pressing the lower two buttons for 3 seconds. "ITALY TEST" will blink; press the lower right button to confirm. The test sequence includes UH (high off limit AC voltage), UL (low off limit AC voltage), FH (high off limit AC frequency), and FL (low off limit AC frequency). After each test, confirm the result. The standard reclosure time of 300 seconds is reduced to 10 seconds for testing. Test accuracy is better than 1V/0.1Hz if grid voltage and frequency are stable.
UH-test
Starts by pressing "Start". The screen shows test time, measured grid voltage (UG), and the high voltage limit (UH). During the test, UH decreases until it reaches UG, causing the inverter to disconnect and the red error LED to illuminate. After the test, TIME, UG, and UT (measured UH) are displayed. Calculation: UT = UG + (TIME * 11.5).
UL-test
Starts by pressing "Start". The screen shows test time, measured grid voltage (UG), and the low voltage limit (UL). During the test, UL increases until it reaches UG, causing the inverter to disconnect and the red error LED to illuminate. After the test, TIME, UG, and UT (measured UL) are displayed. Calculation: UT = UG – (TIME * 11.5).
FH-test
Starts by pressing "Start". The screen shows test time, measured grid frequency (FG), and the high frequency limit (FH). During the test, FH decreases until it reaches FG, causing the inverter to disconnect and the red error LED to illuminate. After the test, TIME, FG, and FT (measured FH) are displayed. Calculation: FT = FG + (TIME * 0.05).
FL-test
Starts by pressing "Start". The screen shows test time, measured grid frequency (FG), and the low frequency limit (FL). During the test, FL increases until it reaches FG, causing the inverter to disconnect and the red error LED to illuminate. After the test, TIME, FG, and FT (measured FL) are displayed. Calculation: FT = FG – (TIME * 0.05).
