Sunpal vs Growatt: The Smart Inverter Choice for Homeowners and Installers in Malaysia

Looking for the best solar inverter for your home or client installations? While Growatt is a well-known name in the solar industry, many homeowners and installers in Malaysia are turning to Sunpal inverters for better reliability, service, and overall value.

Why Your Inverter Choice Matters

A solar inverter is the heart of any solar power system. It converts the electricity generated by your panels into usable power for your home and appliances. But not all inverters are built the same. Factors like reliability, support, outdoor durability, and warranty service can make a big difference over time.

Real-World Reliability: Sunpal Leads the Way

  • Sunpal: IP65-rated for outdoor use, proven MPPT stability, fewer user-reported failures.
  • Growatt: Reports of bulging capacitors, internal board failures, and long wait times for support.

Warranty & Support: Sunpal Delivers Local Service

  • 2-year standard warranty on all residential Sunpal hybrid inverters
  • Free repair or replacement for verified component issues
  • Fast, local support in Malaysia from the Sunpal Enterprise team in Kuching

Growatt, while offering a 1-year warranty, has inconsistent support quality with long response times and complicated return processes. Sunpal customers enjoy double the warranty coverage and responsive service from a Malaysian-based team.
