b) Mark the hole location and drill holes;
Ÿ Place the assembled transverse plate and base support on the wall, look the
cylindrical plastic bubble spirit level on the transverse plate. If the bubble
isn't in the center, slightly bow it to the horizontal.
Ÿ Then determine the position of holes.
Ÿ Mark it with a marker.

c) Secure the assembled transverse plate on the wall;
(1) Place the assembled Transverse Plate and Base Support to the wall (or solid
wood wall);
(2) Attach screws to the holes
e) The steps of mounting battery modules, BMS and inverter are same as
the floor-mounting's. Please refer to “7.3 Floor-mounting” for more details.
• In the case of the concrete wall, attach the M8*85 Expansion Screw (× 4) to the
holes but be sure not to tighten (Torque: 10 N·m);
• Or, in the case of solid wood wall, attach M8*89 Self-tapping Screw (x 4) to the
holes but be sure not to tighten (Torque: 10 N·m);
(3) Check whether the cylindrical plastic bubble spirit level is horizontal;
(4) Hammer Expansion Screws with a rubber mallet (expect solid wood wall), and
tighten it with torque wrench.
