4.0 Electrical Connections
Electric Shock Hazard:
Before doing any electrical connection, ensure the PV switch, A, C and BAT circuit breaker are switched OFF and
cannot be reactivated .
DANGER
You must protect each inverter with an individual grid and backup circuit breaker in order to ensure that the
inverter can be disconnected safety .
DANGER
Selecting a circuit breaker and conductor cross-section
The maximum allowable grid circuit breaker specification is 50 A when the copper conductor cross-section for grid
connection is 10 mm² and factors influencing the ampacity of the cable, other influences on dimensioning must be
considered. You may use SunPower One installer dashboard to adjust the grid circuit breaker specification from 32
DANGER
A to 40 A, otherwise the circuit breaker may trip under normal operation conditions .
