Battery Connection - Phocos Any-Grid Series User And Installation Manual

•
Ensure a minimum distance to other objects and surfaces as shown in
Fig. 5.1 to guarantee sufficient heat dissipation and to have enough space
for removing wires.
•
Install in a room where noise is not an issue as the unit has
fans for cooling. Under maximum load, the fan noise
typically does not exceed 60 dBa. Under no load, but with
the AC output turned on, the minimum noise is
approximately 35 dBa, as the fans rotate at about 30% of
their maximum speed.The fans are speed-controlled
according to current PV and inverter power. Air is taken in
from the top vents and expelled toward the bottom.
Install the unit by using four (PSW-H-5KW-120/48V, PSW-H-6.5KW-
120/48V and PSW-H-8KW-230/48V) or three (all other models) M4 or
M5 screws (Fig. 5.2) appropriate for the weight of the unit and wall
material, use wall plugs. The bottom screw hole is only accessible after
removal of the bottom cover (Fig. 4). This bottom cover must remain
removed for the rest of this "Installation" chapter until instructed
otherwise.
