6.3 AC Connection

6.3.1 Requirements for the AC ConnectionCable requirements:

☐ Cable made of aluminum or copper. When using cables made of aluminium, a bimetal ringterminal lug made of copper and aluminium must be used.

☐ External diameter: 25 mm to 38 mm☐ Conductor cross-section for SOLID-Q 50: 16 mm² to 35 mm²☐ Conductor cross-section for SOLID-Q Pro 60: 25 mm² to 50 mm²☐ Insulation stripping length: 18 mm☐ Sheath stripping length: 90 mm☐ The cable must be dimensioned in accordance with the local and national directives for the

dimensioning of cables. The requirements for the minimum wire size derive from thesedirectives. Factors influencing cable dimensioning include nominal AC current, cable type,routing method, cable bundling, ambient temperature and maximum desired line losses.



Overvoltage category:The inverter can be used in grids of overvoltage category III or lower in accordance withIEC 60664-1. That means that the inverter can be permanently connected to the grid-connectionpoint of a building. In case of installations with long outdoor cabling routes, additional measures toreduce overvoltage category IV to overvoltage category III are required (see the TechnicalInformation "Overvoltage Protection" at www.SMA-Solar.com).

Additional grounding:Connection of additional groundingIn some countries, additional grounding is generally required. In each case, observe thelocally applicable regulations.

• If additional grounding is required, connect an additional grounding that has at least thesame cross-section as the connected grounding conductor to the connecting terminalplate for the AC cable (see Section 6.3.3, page 26). This prevents touch current if thegrounding conductor at the connecting terminal plate for the AC cable fails.

6.3.2 Connecting the Inverter to the Utility Grid

Additionally required mounting material:☐ Ring terminal lug with hole diameter: 6 mm

Requirements:☐ The connection requirements of the grid operator must be met.☐ The grid voltage must be within the permissible range. The exact operating range of the

inverter is specified in the operating parameters.

Procedure:1. Disconnect the circuit breaker from all three line conductors and secure against reconnection.2. If the lower enclosure lid is mounted, loosen all

screws of the lower enclosure lid using a Torxscrewdriver (TX 25) and remove the enclosure lid.

12.2 Checking the PV System for Ground Faults





Procedure:In order to check the PV system for ground faults, perform the following actions in the prescribedorder. The exact procedure is described in the following sections.

• Check the PV system for ground faults by measuring the voltage.• If the voltage measurement was not successful, check the PV system via insulation resistance

measurement for ground faults.

Test by Measuring the VoltageProceed as follows to check each string in the PV system for ground faults.

Procedure:

1. DANGERDanger to life due to high voltages

• Disconnect the inverter from all voltage sources (see Section 10, page 57).

2. Measure the voltages:• Measure the voltage between the positive terminal and the ground potential (PE).• Measure the voltage between the negative terminal and the ground potential (PE).• Measure the voltage between the positive and negative terminals.

If the following results are present at the same time, there is a ground fault in the PVsystem:

☑ All measured voltages are stable.☑ The sum of the two voltages to ground potential is approximately equal to the

voltage between the positive and negative terminals.• If a ground fault is present, determine the location of the ground fault via the ratio of the

two measured voltages and eliminate the ground fault.

Example: Location of the ground faultThe example shows a ground fault between the second and third PV module.

3. If a definite ground fault cannot be measured and the message is still displayed, measure theinsulation resistance.

4. Reconnect the strings without ground faults to the inverter and recommission the inverter.

Test by Measuring the Insulation ResistanceIf the voltage measurement does not provide sufficient evidence of a ground fault, the insulationresistance measurement can provide more exact results.

Required devices:☐ Suitable device for safe disconnection and short-circuiting☐ Measuring device for insulation resistance

Procedure:1. Calculate the expected insulation resistance per string.





3. Install the short circuit device.4. Connect the measuring device for insulation resistance.5. Short-circuit the first string.6. Set the test voltage. The test voltage should be as close as possible to the maximum system

voltage of the PV modules but must not exceed it (see datasheet of the PV modules).7. Measure the insulation resistance.8. Eliminate the short circuit.9. Measure the remaining strings in the same manner.

☑ If the insulation resistance of a string deviates considerably from the theoreticallycalculated value, there is a ground fault present in that string.

10. Reconnect to the inverter only those strings from which the ground fault has been eliminated.11. Reconnect all other strings to the inverter.12. Recommission the inverter.13. If the inverter still displays an insulation error, contact the Service (see Section 15 "Contact",

page 72). The PV modules might not be suitable for the inverter in the present quantity.
