FAQ

Can 380V inverters work with residential solar panels?

While technically possible, they're generally overkill for homes. Consider them when system size exceeds 30kW.

How does ambient temperature affect performance?

Quality models maintain full output up to 45°C, with derating typically starting at 50°C.

What's the typical lifespan?

Properly maintained units operate 12-15 years before efficiency drops below 90%.

Note: Technical specifications may vary by manufacturer. Always consult certified solar engineers for project-specific advice.
