Reading the state of 68 inverters across an operating French PV portfolio, and what O&M practice had done to them

Elysia holds an operating PV portfolio of 120 MW in France whose plants run on a single central-inverter family. Inverter condition in a fleet of that age is rarely a purely technical matter: it depends on how the units have been maintained, and poor maintenance practice shifts liability towards the O&M provider. Elysia needed both readings at once — the physical condition of the components and the contractual exposure attached to it — before deciding where value could still be recovered.

One Hub Energy worked as independent technical advisor on a desktop basis, covering the client's PV plants equipped with that inverter family: 68 units across seven sites. We assessed component health across the fleet rather than site by site, so that recurring failure patterns could be separated from one-off events. In parallel we reviewed the inverter maintenance practices actually applied and traced the O&M service liabilities they gave rise to. The two strands were then read together to identify where value recovery was potentially available to the owner.
