3.2kW Premium Off-Grid Power Plant - Victron MultiPlus-II 5000 & Longi Bifacial Array

The 3.2kW Premium MultiPlus-II Kit is a professional-grade energy ecosystem designed for mission-critical power. This system pairs six Longi 540W Bifacial Solar Panels—which capture sunlight from both sides to maximize energy harvest—with the Victron MultiPlus-II 48/5000/70-100. This next-generation inverter/charger provides 5000VA of pure sine wave power with enhanced efficiency and professional-grade features for 120V off-grid or backup applications.

With an estimated daily production of 15kWh (plus bifacial gain), this kit provides the robust power needed for full-time off-grid living, including air conditioning, well pumps, and power tools. The high-voltage Victron SmartSolar 250/60 MPPT allows for longer panel strings, reducing wiring complexity and maximizing conversion efficiency in all weather conditions.

What’s Included in This Master Kit:

• 6x Longi 540W Bifacial Panels (88.5"x44.5"): High-efficiency modules that capture reflected light on the backside for significantly increased daily energy yield.
• Victron MultiPlus-II 48/5000/70-100: The latest generation 48V inverter/charger. 4000W continuous output, 9000W peak surge, and a massive 70A battery charger.
• Victron SmartSolar 250/60 MPPT: High-voltage 60A controller with integrated Bluetooth for real-time smartphone monitoring and configuration.
• MidNite Solar Protection: Dedicated breaker box with 40A and 63A DC breakers for professional-grade safety.
• Heavy-Duty DC Infrastructure: A pair of 5ft 2/0 gauge inverter cables, 5ft #6 controller-battery cables, and a 250A fuse for ultimate current protection.
• Complete Wiring Package: 30ft #10 MC4 cables, 6ft extensions, and MC4 2-1 connectors for flexible high-voltage stringing.
• Victron MK3-USB: Essential interface for advanced programming and firmware updates of the MultiPlus-II.

Technical Specifications:

Technical Tip: The MultiPlus-II is designed for seamless integration with external current sensors and GX devices (like the Cerbo GX). To maximize the performance of the Bifacial Longi panels, ensure they are mounted at least 2 feet above a reflective surface.
