Which inverter is required for a combined PV and storage system?

Combined PV and storage system topologies will generally require a bi-directional inverter, either as the primary inverter solution (DC-coupled) or in addition to the unidirectional PV inverters (AC-coupled).

Why should a technician service a central inverter versus a micro-inverter?

A technician will be dispatched faster to service a central inverter (see Appendix C for corrective maintenance choices for both string and central inverters), whereas failures of micro-inverters, and to a lesser extent string inverters, can be delayed until a scheduled visit because their impact on the performance of a large plant is incremental.
