Inverter Replacement FAQs

Standard string inverter replacement ranges from $2,500–$4,500 installed. Hybrid inverters cost $5,000–$7,500. Price depends on inverter type, switchboard upgrades, and warranty support.
Common signs include: error codes on the display, system shutdowns, reduced output despite sunny weather, audible buzzing or grinding, or complete failure to produce power. Our Inverter Health Check diagnoses the issue.
A typical replacement takes 2–4 hours. We disconnect the old inverter, install the new one, run safety tests, and reconnect your system. Most jobs completed same-day.
Many inverters have 10-year warranties. We help with warranty claims, coordinate with manufacturers, and handle all paperwork. You may receive partial or full refund.
If you're planning to add battery storage later, a hybrid inverter is worth the extra cost now. Otherwise, a standard string inverter is fine. We'll recommend based on your future plans.
We install Fronius, SMA, Sungrow, Huawei, and Growatt inverters. We recommend based on your system type, budget, and compatibility with existing equipment.
