Installation

altitude_note modules are terrestrial use only; high-altitude influence must be considered but no numeric maximum is given (manual p.5)
bifacial_mounting_height_m 0.5 to 2 m (bifacial modules, manual p.17)
bolt_torque M8 16-20 N.m; M6 14-18 N.m (manual pp.18-19)
cable_connector_force_limit_n 60
clamp_requirements clamp contact depth 7 mm <= D <= 10 mm; length >= 50 mm; thickness >= 3 mm (manual pp.18-19)
design_load_note Load-table values (e.g. +5400 / -2400 Pa for methods A2, A3, B2, B3) are laboratory static mechanical test loads; apply a 1.5 safety factor (manual pp.22-26)
grounding phi 4 mm grounding hole; M4 x 12 mm bolt with star and plain washers; torque 4-8 N.m (manual p.32)
installation_humidity_range < 85 % RH (manual p.14)
installation_temperature_range_c recommended -20 to +50; extreme -40 to +85 (manual Table 7-1, p.14)
minimum_clearance_to_surface_mm 115
minimum_tilt_deg 10
mounting_hole phi 9 x 20 mm for M8 bolts; phi 7 x 10 mm for M6 bolts (manual p.18)
mounting_methods M8 or M6 bolt sets through frame holes, or at least four clamps (Risen installation manual pp.18-19)
recommended_tilt_by_latitude 15 deg for 0-15 deg latitude, up to 'same latitude +20 deg' above 40 deg latitude (manual Table 7-2, p.15)
short_side_mounting_note short-side installation 65 mm <= L1 <= 1/4 B, with load limits front <= 1800 Pa, reverse side <= 1200 Pa (manual p.27)

Environment

salt_mist_resistance IEC 61701 salt mist method 6 and method 8 referenced (manual p.15)

Interfaces & connectors

cable_requirements PV cables rated to 90 C, UV resistant, cross-section 4 mm2 / 12 AWG (manual p.30)

Protection

over_current if the number of parallel strings >= 2 there must be an over-current protection device on each string; maximum over-current protection 30 A (manual pp.29-30)
string_sizing_rule Maximum system voltage V >= N x Voc x [1 + beta x (Tmin - 25)] (manual pp.29-30)
