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 Evolve Hub and the Evolve ESS. (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 Evolve 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.
