Assembling The Dc Connectors - SMA SUNNY TRIPOWER 5.0 SMART ENERGY Operating Manual

SMA Solar Technology AG
☐ All PV modules should be aligned and tilted identically.
☐ On the coldest day based on statistical records, the open-circuit voltage of the PV array must
never exceed the maximum input voltage of the inverter.
☐ The same number of series-connected PV modules must be connected to each string.
☐ The maximum short-circuit current of a string must not exceed the maximum short-circuit current
of the inverter (see Section 16, page 122).
☐ The thresholds for the input voltage of the inverter must be adhered to (see Section 16,
page 122).
☐ The maximum usable input power may be exceeded (see Section 16, page 122). The power
exceeding the specified value cannot be used.
☐ The positive connection cables of the PV modules must be equipped with positive DC
connectors (see Section 7.6.2, page 55).
☐ The negative connection cables of the PV modules must be equipped with the negative DC
connectors (see Section 7.6.2, page 55).
Use of Y adapters for parallel connection of strings
The Y adapters must not be used to interrupt the DC circuit.
• Do not use the Y adapters in the immediate vicinity of the inverter. The adapters must not
be visible or freely accessible.
• In order to interrupt the DC circuit, always disconnect the inverter as described in this
document (see Section 10, page 86).

Assembling the DC Connectors

Danger to life due to electric shock when live components or DC cables are
touched
The DC cables connected to a battery or a PV module may be live. Touching live DC cables
results in death or serious injury due to electric shock.
• Disconnect the product and battery from voltage sources and make sure it cannot be
reconnected before working on the device.
• Observe all safety information of the battery manufacturer.
• Do not touch non-insulated parts or cables.
• Do not disconnect the DC connectors under load.
• Wear suitable personal protective equipment for all work on the product.
