5.3 Setting a custom grid standard

WARNING
● Failure to set the correct grid standard could result in improper operation
of the inverter, inverter damage or the inverter not operating at all.
● Only certified personnel should set the grid standard.
● Only set the grid configuration that is approved by your location and
national grid standards.

5.4 Preliminary checks

WARNING
High Voltage.
AC and DC measurements should be made only by qualified personnel.

5.4.1 DC Connections

Verify DC connections.
1). Lightly tug on each DC cable to ensure it is fully captured in the terminal.
2). Visually check for any stray strands that may not be inserted in the terminal.
3). Check to ensure the terminal screws are the correct torque.

5.4.2 AC Connections

Verify AC connections.
1). Lightly tug on each AC cable to ensure it is fully captured in the terminal.
2). Visually check for any stray strands that may not be inserted in the terminal.
3). Check to ensure the terminal screws are the correct torque.

5.4.3 DC configuration

Verify DC configuration by noting the number of panels in a string and the string voltage.
5.4.3.1 VOC and Polarity
Measure VOC, and check string polarity. Ensure both are correct and VOC is in specification.
WARNING
Input voltages higher than the maximum value accepted by the inverter
(see "Specifications" in section 10) may damage the inverter.
Although Solis inverters feature reverse polarity protection,
prolonged connection in reverse polarity may damage these protection
circuits and/or the inverter.
5.4.3.2 Leakage to ground
Measure leakage to ground to check for a DC ground fault.
