It offers the dependability of the 18kPV with more flexibility and power. It accepts 21kW of usable PV (24kW max input) on three MPPTs and delivers 16kW AC with solar or 12kW from batteries alone, enough to start a 5-ton air conditioner. It can pass through 90A of grid power. Parallel up to 16 units for as much as 256kW of continuous output with PV, and pair it with the EG4 GridBOSS MID to manage the entire energy storage system while cutting installation cost.\u003c\/p\u003e\u003ch3\u003eHighlights\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible operation:\u003c\/strong\u003e off-grid, grid-supported, or exporting excess solar to the grid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh PV voltage:\u003c\/strong\u003e up to 600VDC, which allows smaller conductor sizes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree MPPTs\u003c\/strong\u003e for flexible array design\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBig-load capable:\u003c\/strong\u003e starts a 5-ton AC unit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScalable:\u003c\/strong\u003e parallel up to 16 units (256kW continuous with PV)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmart connectivity:\u003c\/strong\u003e Wi-Fi remote management with mobile notifications and remote settings; closed-loop communication with compatible batteries\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety:\u003c\/strong\u003e rapid shutdown, ground-fault monitoring and arc-fault protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eListings:\u003c\/strong\u003e UL 1741 Certificate of Compliance; CEC Solar Equipment List\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGridBOSS integration\u003c\/strong\u003e for whole-home load management\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePV input\u003c\/td\u003e\n\u003ctd\u003e21kW usable \/ 24kW max\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax PV voltage\u003c\/td\u003e\n\u003ctd\u003e600VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMPPTs\u003c\/td\u003e\n\u003ctd\u003e3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOn-grid AC output\u003c\/td\u003e\n\u003ctd\u003e16kW @ 240V; 13.8kW @ 208V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery-only output\u003c\/td\u003e\n\u003ctd\u003e12kW (12,000VA)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal output current\u003c\/td\u003e\n\u003ctd\u003e50A (66.7A max continuous)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput voltage\u003c\/td\u003e\n\u003ctd\u003e120\/240V, 120\/208V, 240V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGrid passthrough\u003c\/td\u003e\n\u003ctd\u003e90A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery voltage\u003c\/td\u003e\n\u003ctd\u003e48V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eParallel\u003c\/td\u003e\n\u003ctd\u003eUp to 16 units\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e30.4 × 22.3 × 11.2 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e121 lbs (55 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e10-year EG4 manufacturer warranty\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003eThe EG4 FlexBOSS LCD Screen Kit is sold separately.\u003c\/p\u003e","brand":"EG4 Electronics","offers":[{"title":"Default Title","offer_id":44582448398414,"sku":"1526018-02","price":3599.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/9064\/9678\/files\/eg4-flexboss21-16kw-ac-hybrid-inverter-7407211.jpg?v=1792435749","url":"https:\/\/skysolarusa.com\/products\/eg4-flexboss21-16kw-ac-hybrid-inverter","provider":"Sky Solar USA","version":"1.0","type":"link"}
