Unlike the standard i-series, the Heli model adds an azimuth bearing — a double-race plain bearing with grease nipples for periodic re-lubrication — letting the nacelle track wind direction more precisely. Repeller blades and nacelle cover are hand-laminated and painted, not injection molded, for tighter tolerances at this power class.\u003c\/p\u003e\n\n\u003cp style=\"color:#1061EE;font-size:12px;font-weight:600;letter-spacing:0.06em;text-transform:uppercase;margin-bottom:6px\"\u003eGrid-Tie Ready\u003c\/p\u003e\n\u003ch3 style=\"color:#1B3C65;font-size:17px;font-weight:700;margin-bottom:10px\"\u003eWhat On-Grid Configuration Means\u003c\/h3\u003e\n\u003cp style=\"color:#333333;font-size:15px;line-height:1.75;margin-bottom:20px\"\u003eThis is the on-grid variant, wired for direct feed-in through a compatible grid-tie inverter rather than battery charging. Feed begins at approximately 100 RPM, with an evenly increasing performance curve up to rated output. A separate rectifier handles both directions of rotation for consistent power delivery regardless of wind shift. This turbine requires a compatible grid-tie inverter, sold separately — see our Complete Heli 4KW Installation Kit if you need the turbine, inverter, and controller bundled together.\u003c\/p\u003e\n\n\u003cdiv style=\"background:#FFF8E7;border:1px solid #FFD166;border-radius:6px;padding:12px 16px;margin-bottom:20px\"\u003e\n\u003cp
