The 30% Rule: When It's Worth Repairing vs Replacing
Ozora Soluções explains everything about the 30% rule for inverter repair based on more than 14 years of experience in solar inverter and industrial drive repairs in São Paulo.
What you need to know about the 30% rule for inverter repair
Understanding the 30% rule for inverter repair is fundamental to making the right decision: to repair, replace, or prevent future problems. The solar inverter is the most critical component of the photovoltaic system — when it stops, all generation ceases.
Correct diagnosis — the most important step
The most common mistake is making decisions without an adequate technical diagnosis. Buying new equipment when the defect was simple and cheap to repair is a waste that we frequently see in our laboratory.
Ozora performs a free diagnosis with a technical report in up to 24 hours. The report identifies the root cause, lists the components to be replaced, and presents the quote before any decision is made.
The 30% Rule
If the cost of repair is less than 30% of the value of equivalent new equipment, repair is always the economically correct decision. In practice, most repairs at Ozora cost between 10% and 25% of the price of a new unit.
Preventive maintenance
The best way to avoid problems is through annual preventive maintenance: internal cleaning, capacitor checks, renewal of thermal paste, testing of sensors and relays, and firmware updates when available.
