Internal consumption
The internal consumption of the Sunny Island discharges the battery. In standby mode, this
load is about 4 W and about 25 W in idle mode. Observe this when you install the Sunny
Island, but do not use it immediately or do not use it for an extended period of time within
the year.
It may be necessary to set the Sunny Island to Stop mode (see section 9.3”Switching Off”
(page64)) and disconnect it from the battery by means of the DC circuit breaker.
Installation altitude
The Sunny Island has been designed for use at elevations of up to 3000 m above sea level.
Please contact SMA Solar Technology before using the device at elevations above
3000 m.
A performance loss of 0.5 % per 100 m is to be expected starting at an elevation of
2000 m above sea level!
