Select your required power rating from the variant options above.

Why the Growatt MIN XH-US?

Most grid-tie inverters do one job. The MIN XH-US does five. It converts solar power, manages battery storage, handles backup power, supports whole-home energy modes, and reports real-time performance to your phone — all from a single compact wall-mount unit certified for Canadian and US installations.

Key Features

• Up to 98.5% Peak Efficiency — industry-leading conversion keeps more of your solar harvest working for you.
• DC & AC Coupled — pairs with new solar arrays or retrofits into existing grid-tie systems without rewiring.
• Dual to 4-String MPPT — multiple independent trackers (model-dependent) squeeze maximum power from shaded or mixed-orientation arrays.
• Flexible Energy Modes — Self-Consumption, Zero Export, Time of Use (TOU), and Off-Grid modes let you optimize for savings, grid compliance, or full independence.
• Backup Power & Dark Start — keeps critical loads running during grid outages; dark start restores the inverter without grid power.
• Wide Battery Compatibility — works with Growatt ARO/APX HV, LG Prime Gen3, and other LFP/lithium battery systems.
• Smart Monitoring — optional WiFi/4G module + RS485 + revenue-grade meter (ANSI C12.20) for utility-compliant reporting.
• Built-in Safety — Rapid Shutdown (RSD) and Arc Fault Circuit Interrupter (AFCI) are standard on every model.
• Standards Compliant — certified to UL1741SA/SB, CA Rule 21, HECO, and compatible with Canadian net metering programs.
• 10-Year Manufacturer Warranty — backed by Growatt with extension options available.

What Can It Power?

• Whole-Home or Partial-Home Backup — pair with battery storage for seamless outage coverage.
• Net Metering — export surplus generation and earn credits on your utility bill.
• Time-of-Use Optimization — charge batteries at off-peak rates, discharge during peak pricing windows.
• Zero-Export Compliance — ideal for properties where grid export is restricted.
• Off-Grid Transition — off-grid mode supports full energy independence when combined with adequate battery capacity.
