Anchoring the PV225S
The PV225S is designed to be installed in either an indoor or outdoor location. It
must be placed on and anchored to a level concrete floor or pad. The concrete
floor or pad, upon which the PV225S is anchored, must be structurally designed to
meet any local, state, or national requirements for weight, seismic, and wind sheer
if applicable.
Four 5/8" holes are provided in the feet of the main inverter, and six 5/8" holes are
provided in the feet of the AC interface/transformer assembly for anchoring to the
floor or pad.
Figure 2-9 and Figure 2-10 depict the layout patterns of the anchoring holes for
both the PV225S main inverter and the AC interface/transformer assembly.
