2.2 Installation conduit plan – power and communication circuits
The following example outlines the conduit plan for power and communication circuits for a complete solar plus
storage system using the DURACELL HUB and the DURACELL POWER CENTER 5KW. (String PV inverter shown –
replace with equivalent AC combined micro-inverter output, where applicable).

Note 1: Conductor type referenced where Hub is installed greater than 24" from the ESS. Signal wiring routed in
conduit with power must be 300V rated. For runs longer than 10 meters, signal separation from power is
recommended to minimize signal interference.
