Installation process standard for household photovoltaic power station.

General requirements for the installation of household photovoltaic power stations (personnel requirements, tool requirements, protection requirements, environmental requirements; General requirements -- roof perforation waterproof treatment, details of tightening torque of screws or bolts of each type, expansion installation requirements of each type, welding requirements, lap requirements, precast concrete foundation)

Bracket installation -- foundation construction -- household photovoltaic foundation type, large bend hook, front pull back pull, expansion bolt/chemical anchor bolt, precast concrete foundation, sun room foundation, yard support screw pile, foundation axis and elevation deviation)

Bracket installation - bracket installation (inclined roof installation steps, inclined roof (front pull and back pull) installation steps, inclined roof (Dawangou) installation steps, flat roof construction points, flat roof windproof back pull installation; Flat roofing - Installation nodes (installation diagram of column and channel base (mixed pure soil foundation), installation diagram of column and channel base (expansion bolts), installation nodes of column and inclined beam cross, beam and inclined beam......) ; Flat roof - installation deviation; Support installation - Sun room installation steps)

Component installation (Installation steps: component handling → Positioning and pay-off → Component sequential installation → Wiring → line check → Appearance cleaning; Block mounting node (pay-off positioning -- vertical component positioning and installation requirements, horizontal component positioning and installation requirements, component grounding (equipotential cable), water guide clamp installation, snow separator installation, component installation tolerance)

Inverter installation: Installation procedure: Unpack check → Determine the installation position → Inverter installation → AC cable connection; Inverter type steel installation allows deviation

Combined cage installation: Installation steps: unpacking inspection → Combined cage installation → loop crimping and fixing → insulation rolling test

Line laying: Installation steps: inspection → laying → testing → sealing → power grid access; Procedure For installing insulation puncture

Lightning protection grounding: Installation steps: lead down installation → grounding body installation → grounding resistance detection; The lead down line is connected with the support, the lead down line is laid along the wall, and the net box leads down the line
