Life-threatening voltages and currents occur within the Sunny
Island 3324/4248. Protection against accidental contact is only
guaranteed if the following points are followed according to the
installation manual:
• the inverter is mounted correctly
• all connections to the inverter are made correctly
• the inverter is properly grounded
• the housing cover is subsequently securely closed
If you believe that any of these requirements are not fulfilled,
contact your installer immediately, as ignoring any of these points
may cause life-threatening personal injuries due to the voltages
present (electric shock) or may cause damage to parts of the
system.
Only qualified personnel may mount and install the battery and
the Sunny Island 3324/4248. Handling batteries is dangerous, e.g.
batteries can produce very high currents if they are short-circuited.
All of the safety instructions and general instructions in the
installation manual must be observed.
Use only rechargeable lead acid batteries. The use of other types
of battery can lead to personal injury and material damage.
Open flame or smoking in the vicinity of the battery is NOT
permitted under ANY CIRCUMSTANCES.
Take care to ensure that no metal parts fall onto the battery. This
could short-circuit the battery or other electrical components, which
could cause a fire or an explosion.
Ensure that the battery room is sufficiently ventilated.
The own consumption of the Sunny Island 3324/4248 discharges
the batteries, in standby mode (inverter DC disconnect is on,
inverter is in STOP mode and must be started manually) this load
is about 4 W and in idle mode (inverter is on, in invert mode, no
AC loads are present) it is about 22 W. You should take note of this
when operating the Sunny Island 3324/4248 for longer times
without recharge possibilities (e.g. in winter with snow on your
modules).
In these cases, you should set the Sunny Island 3324/4248 to Stop
mode (see section 9.3 "Switching Off" (S. 83)) and disconnect it
from the batteries via the DC circuit breaker.
