Key Technical Advantages

Optimized for High-Power Modules

The global shift toward high-wattage panels demands higher current handling. The SOFAR G3 series features a Max. Input MPPT Current of 20A, making it fully compatible with 500W+ high-power solar panels. This ensures your installations are future-proof and capable of capturing maximum energy from the latest bifacial and large-cell modules.

Advanced Safety & Protection

Reliability is non-negotiable for professional PV string inverter deployments. Our G3 series comes standard with integrated safety features to reduce BOS (Balance of System) costs:

Integrated DC Switch: For safe and easy maintenance.

Surge Protection: Built-in Type II SPD for both DC and AC sides.

Active Safety: Optional AFCI (Arc Fault Circuit Interrupter) to detect and mitigate fire risks.

Durability: IP65 rated enclosure for long-term outdoor reliability in harsh environments.

FAQ

Q: How does the inverter perform during early morning or late afternoon when solar radiation is low?

A: It excels in low-light conditions thanks to an ultra-low **70V start-up voltage**. This allows the system to begin grid-feeding much earlier and shut down later than competitors with higher start-up thresholds.

Q: Does the single MPPT design limit the flexibility of roof orientation?

A: While featuring a single MPPT, this unit is optimized for residential rooftops where panels are typically on a single plane. For complex roofs, its wide MPPT voltage range (50V–550V) ensures maximum energy harvest even with shorter strings.

Q: What monitoring options are available for the end-user and the installer?

A: We offer a multi-platform monitoring ecosystem. You can choose between WiFi, GPRS, or RS485 communication sticks. Installers can manage entire fleets via our professional portal, while homeowners use a user-friendly mobile app.

Q: How long does the physical installation typically take for a single technician?

A: The G3 series is ultra-compact and lightweight. With a simple wall-mount bracket and Plug-and-Play connectors, a single technician can complete the physical installation and commissioning in under 20 minutes.

Q: If a fault occurs, how is the diagnostic process handled?

A: The inverter features intelligent PV-array string fault monitoring. Error codes are displayed on the LCD/LED and pushed via the app, allowing for remote troubleshooting before a technician even arrives on-site.
