What moves the price of an inverter replacement
Inverter type moves the price most. A single string inverter on a wall is one unit and one visit. Microinverters fail one at a time, so a single replacement is a roof job priced per unit, while replacing them all is a larger project (inverter types explained).
Like-for-like or upgrade is the second decision. A failed string inverter can be replaced with the same model, or with a hybrid inverter that is ready for a battery; that costs more now and avoids a second inverter later (adding a battery). Discontinued models may force a redesign and new permit.
Price by size and equipment
| Inverter | What the job involves |
|---|---|
| String inverter | One wall-mounted unit; ground-level work |
| Hybrid (battery-ready) inverter | Replacement plus battery readiness |
| One microinverter | Roof access, panel off and on |
| Optimizer system inverter | Central unit; optimizers stay if compatible |
