Dual AC input and output connections combine with two independent MPPT solar controllers and a combined 12kW of PV input capacity, giving installers a single unit capable of serious off-grid duty with full parallel expansion.\u003c\/p\u003e\u003ch2\u003eKey features of this 11kW off grid inverter\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous output\u003c\/strong\u003e, 11kW with 22kVA surge capacity\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual AC architecture\u003c\/strong\u003e, independent inputs and outputs for split or independent load management\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolar charging\u003c\/strong\u003e, two independent MPPT solar chargers, up to 12kW total PV input\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eParallel operation\u003c\/strong\u003e, up to 6 units for large-scale off-grid systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery input\u003c\/strong\u003e, 48V with 150A combined charging current\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWaveform\u003c\/strong\u003e, pure sine wave output for sensitive equipment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommunication and protection\u003c\/h2\u003e\u003cp\u003eThe Ultra-Max communicates via USB, RS232, RS485, Wi-Fi and Bluetooth, and includes built-in dry contact, GFCI, rapid shutdown and AFCI detection support.\u003c\/p\u003e\u003ch2\u003eProduct overview\u003c\/h2\u003e\u003cp\u003eBuilt for demanding off-grid environments, the Ultra-Max pairs a high-output inverter with dual MPPT solar chargers and an AC charger in one enclosure. The dual AC design lets installers wire critical and non-critical loads separately, with precise control over priority and switching behaviour.\u003c\/p\u003e\u003cp\u003eMPPT voltage range runs from 90V to 450VDC, with open circuit voltage up to 500VDC, so the system accepts a wide range of PV string configurations. Battery charging supports both lead-acid and lithium chemistries. Up to six units can be paralleled for installations needing 66kW or more of off-grid capacity.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eSuited to large residential off-grid solar systems, commercial and agricultural installations, critical backup power for business continuity, remote sites and telecom infrastructure, and high-capacity battery storage systems.\u003c\/p\u003e\u003ch2\u003eWhat's in the box\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConversol 11kW Ultra-Max off-grid inverter\/charger unit\u003c\/li\u003e\n\u003cli\u003eCommunication cable and accessories\u003c\/li\u003e\n\u003cli\u003eUser manual\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation notes\u003c\/h2\u003e\u003cp\u003eInstallation must be carried out by a qualified electrician or accredited solar installer. Battery cabling, fusing and DC isolators need to be correctly sized, and battery bank voltage, capacity and chemistry must match the inverter configuration before commissioning. Parallel operation requires compatible firmware and synchronisation cabling. Do not install without reviewing the full manual and complying with applicable wiring regulations.\u003c\/p\u003e","brand":"Voltacon","offers":[{"title":"Default Title","offer_id":52053947777312,"sku":"002598","price":1101.45,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1010\/8148\/1504\/files\/ledandsolar-002598-1.webp?v=1785423959","url":"https:\/\/www.ledandsolar.co.uk\/products\/conversol-11kw-off-grid-inverter","provider":"LED \u0026 Solar","version":"1.0","type":"link"}
