4.Electrical Installation
We require that all wiring and electrical connections comply with the appropriate National Electrical Code.
4.1 The electrical characteristics are within ± 10 percent of the indicated values of ISC, VOC, and Pmax under
standard test conditions (irradiance of 1000W/m
4.2 The maximum system voltage is 1500 V。
4.3 The number of PV modules in a series circuit should match with inverter's technology parameters of voltage.
The series voltage of modules that connected together in a series circuit should not higher than the permitted
maximum system voltage under the worst local temperature conditions.
4.4 Under normal conditions, a photovoltaic module is likely to experience conditions that produce more current
and/or voltage than reported at standard test conditions. The requirements of the National Electrical Code (NEC) in

2) Clamp length d=250mm)
Middle clamp is made up of the bottom and
the top half two parts. The material are
aluminum alloy 6063 with lengths of 250
mm. Connect two parts with M8 bolts.
Clamp has
four rubber strips of 2-3 mm
thickness (Suggest to use EPDM rubber)
