“Solar panels last 25+ years — but what about the inverter?”
✅ Great question. Inverters are the heart of your solar system, converting DC to usable AC power for your home.
They don’t last forever — so let’s talk about replacement cost, timing, and how to plan ahead.
⚙️ How Long Does an Inverter Last?
- Average lifespan: 10 to 15 years
- Depends on brand, ventilation, and load usage
- Warranties typically cover 5 to 10 years
High-quality inverters (like Solis, Huawei, SMA) tend to last longer and offer better support.
💰 How Much Does It Cost to Replace?
- 3kW–5kW inverter: RM3,000–RM5,000
- 6kW–10kW inverter: RM5,500–RM9,000
- Includes unit + installation + system configuration
Most users will only need to replace once during the entire 25–30 year panel lifespan.
🛡️ Can You Extend the Lifespan?
✅ Yes! Here’s how:
- Ensure proper ventilation during installation
- Avoid oversizing panels beyond the inverter’s limit
- Use inverters with remote monitoring to catch issues early
📉 What Happens If It Fails?
- You won’t lose your panels — just stop generating power
- Some brands offer advance replacement programs
- With remote support, issues can be diagnosed quickly
✅ Planning Ahead
When calculating ROI, factor in one inverter change mid-way through the solar system life.
