☐ The mounting location must be suitable for the installation of the SunnyMultigate in a

distribution box.

☐ The mounting location must be suitable for the weight and dimensions of the SunnyMultigate

(see Section14 "Technical Data", page66).

☐ The mounting location must be inaccessible to children.

☐ AC cable route of the entire PV system with SunnyMultigate: maximum30m

When installing several SunnyMultigate devices in a PV system, you must lay the AC cable of

each SunnyMultigate to the respective inverter separately in order to guarantee trouble-free

communication between the SunnyMultigate and the inverter.

SunnyMultigate).

☐ A robust support surface must be available for mounting the device, e.g. concrete, walls. In

living areas, ensure that the support surface is not drywall or similar.

☐ The mounting location should be freely and safely accessible at all times without the need for

any auxiliary equipment (such as scaffolding or lifting platforms). Non-fulfillment of these

criteria may restrict servicing.

☐ The mounting location should not be exposed to direct solar irradiation.

☐ Climatic conditions must be met (see Section14 "Technical Data", page66).

☐ The ambient temperature must be between -40°Cand25°C. This will ensure optimal

operation of the SunnyMultigate.

Clearances:

☐ The clearance inside a metal distribution box must be at least 12.7mm to walls or other

components.

☐ Within an industrial closure, observe the following clearances to ensure sufficient ventilation:
