Engineered for installations where other inverters simply aren't rated to go, Emston Tech Inc provides this unit as a robust solution for coastal and high-humidity areas.\n\u003c\/p\u003e\n\n\u003cp\u003e\n  \u003cstrong\u003e13kW Output with Solar, 10kW from Battery — Whole-Home Hybrid Power\u003c\/strong\u003e\n  \u003cbr\u003e\n  The FlexBOSS18 delivers 10,000W of continuous AC output from the battery alone, boosting to 13,000W of combined output when solar production is available. It intelligently blends grid, solar, and battery power to supply your home's full load without waste or manual switching. This solar-assisted boost extends both daily runtime and long-term battery cycle life by reducing the strain on your battery bank.\n\u003c\/p\u003e\n\n\u003cp\u003e\n  \u003cstrong\u003e18kW of Solar Input — Dual MPPT at 600VDC Max\u003c\/strong\u003e\n  \u003cbr\u003e\n  Two independent MPPT charge controllers accept up to 18,000W of combined PV input at up to 600VDC—the maximum allowed under the National Electrical Code.

This provides full protection against windblown dust, rain, hose-directed water, and corrosive salt spray. Whether you are in a coastal climate or a high-humidity region, Emston Tech Inc ensures your system remains protected without the need for additional weatherproofing.\n\u003c\/p\u003e\n\n\u003cp\u003e\n  \u003cstrong\u003eIntegrated Grid Management and Backup\u003c\/strong\u003e\n  \u003cbr\u003e\n  The unit features a built-in 90A transfer switch for seamless grid-to-battery transitions. For a fully integrated experience, pair it with the optional EG4 GridBOSS to eliminate the need for external breakers and additional hardware. It also includes dedicated AUX terminals with generator auto-start functionality, allowing for hands-free management based on your battery's state-of-charge.\n\u003c\/p\u003e\n\n\u003cp\u003e\n  \u003cstrong\u003eKey Features and Technical Capabilities:\u003c\/strong\u003e\n\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRapid Shutdown:\u003c\/strong\u003e Integrated RSD transmitter meets NEC 690.12 requirements for roof-mounted systems.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMultiple Operating Modes:\u003c\/strong\u003e Supports Grid-Tie, Off-Grid, Zero Export, Time-of-Use (TOU), and Force Discharge.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFast Charging:\u003c\/strong\u003e 208A integrated battery charger with closed-loop RS485 and CANBus communication for EG4 and third-party lithium batteries.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdvanced Certifications:\u003c\/strong\u003e UL 1741 SA\/SB, California Rule 21, Hawaii Rule 14H, and IEEE 1547-2018 compliant.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScalability:\u003c\/strong\u003e Parallel up to 10 units for a combined continuous output of 130kW.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEfficiency:\u003c\/strong\u003e Low 60W idle consumption with full remote monitoring and configuration via the EG4 cloud platform.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\n  \u003cstrong\u003e10-Year Warranty\u003c\/strong\u003e\n  \u003cbr\u003e\n  Reflecting our confidence in its long-term durability, the FlexBOSS18 is backed by a 10-year full parts and product replacement warranty through Emston Tech Inc.\n\u003c\/p\u003e","brand":"Emston Tech Inc.","offers":[{"title":"Default Title","offer_id":43243383947382,"sku":null,"price":3257.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0683\/3795\/9030\/files\/2ddb88dc8ff9671eb614380c898b564c.webp?v=1774828885","url":"https:\/\/emston-tech-inc.myshopify.com\/products\/eg4-eg4flexboss18-13kw-hybrid-inverter-charger","provider":"Emston Tech Inc.","version":"1.0","type":"link"}
