Engineered for Complex Scenarios

Independent MPPT ensures 99.8% static efficiency even in challenging conditions.

Dynamic Power Adjustment Increases Yield

HiFlow Pro intelligently adjusts power output under partial shading, so every module works at the optimal level, and your system generates more.

Turn Even the Faintest Light into Solar Harvest

From the first morning rays to the last evening glow, HiFlow Pro microinverter, with its low startup voltage (22V), maximizes your solar harvest—working even in dawn, dusk, or other low-light conditions.

Easy Connection, Full Compatibility

Simpler. Smarter. Faster.

Built-in dual modules enable fast pairing via Bluetooth and stable networking via Wi-Fi — all set up in under 60 seconds.
Precise Power Control

Supports mainstream smart meters like Shelly for accurate export management and smarter power control.

Ultimate Safety and Reliability

Reliable in Any Condition

With an IP67-rated rugged design, our microinverter delivers reliable performance in harsh conditions, from scorching heat to freezing cold (-40°C to +65°C), indoors or outdoors.
34V/1s Safe Cutoff

The microinverter AC plug features intelligent rapid voltage reduction, lowering voltage to safe levels (≤34V) within 1 second after disconnection. This safety mechanism complies with VDE V 0126-95:2024, effectively preventing electric shocks during installation, maintenance, and unexpected outages.
250,000+ Hours Tested

Each product undergoes over 250,000 hours of real-world continuous operation testing, nine manufacturing processes, and thousands of hours of environmental reliability tests that cover high/low temperatures, humidity, condensation, and thermal cycling. Highly Accelerated Life Testing (HALT) further ensures industry-leading durability and reliability.
Data Secured

Your data is stored locally and protected according to GDPR and EU security standards: RED-EN18031 to ensure safe and reliable transmission.
