10KW Complete Offgrid Solar Kit + EG4 FlexBOSS21 + 14.3KW 48V EG4 Lithium Indoor Wall Battery + 11KW Solar with Ground Mount and Wiring

The 10KW Complete Offgrid Solar Kit + EG4 FlexBOSS21 + 14.3KW 48V EG4 Lithium Indoor Wall Battery + 11KW Solar with Ground Mount and Wiring is a powerful, scalable off-grid solution designed for complete off-grid homes, cabins, RVs, garages, and pole barns. With an 11,000W bifacial solar array producing up to 49,500 watts per day (based on 4.5 hours of peak sun) and a 14.3kWh lithium battery bank (approximately 14,300Wh usable), this system is ideal for properties using around 1,400kWh per month and can be expanded over time with additional panels or batteries.

Specifications

• Solar Array: 20× 550W bifacial double-glass solar panels (11,000W total array)

• Inverter/Charger: 1× EG4 FlexBOSS21 versatile 48V split-phase hybrid inverter/charger

• Battery Bank: 1× 14.3kWh 48V EG4 Lithium Indoor Wall Battery (approximately 14,300Wh usable energy)

• Mounting System: Complete IronRidge ground-mount kit including rails, top caps, rail connectors, fasteners, and bolts (uses customer-supplied 3" Schedule 40 pipe)

• Wiring & Components: Solar combiner box, gutter box, Anderson plug battery cable set, 500' PV direct-burial solar wire, 100' 6AWG AC output/input/generator cabling, MC4 crimp kit, and installation manual

Features

• Bifacial Double-Glass Panels: Rear-side energy harvesting up to 25% additional output, enhanced performance in cloudy, hazy, or early-morning conditions, and robust 5400 Pa snow load / 2400 Pa wind load with a 30-year power warranty

• Off-Grid Power for Everyday Loads: Suitable for small cabins, RVs, garages, and pole barns; can run wells, washing machines, fans, TVs, lights, refrigerators, freezers, cell phones, PCs, tablets, and smaller AC systems

• Ground-Mount System: Built around a 3" pipe structure (customer sources 3" Schedule 40 pipe locally), providing a sturdy, serviceable racking solution for long-term outdoor use

• Expandable DIY Kit: All DIY solar kits are expandable, allowing you to add more panels or storage as your energy needs grow. Production estimates use ~4.5 peak sun hours (less in the Northeast, more in the Southwest)

• Hybrid Inverter Performance: EG4 FlexBOSS21 hybrid inverter/charger delivers efficient 48V split-phase power, supporting flexible charging, load management, and integration with your solar and battery system

• DIY-Friendly Installation: Designed for homeowners with basic wiring knowledge; racking and ground-mount setup are typically the most labor-intensive steps. A local electrician can assist with final connections and code compliance if needed

Maintenance

• Daily: Check inverter and battery status; ensure solar panels are free of major debris and shading

• Weekly: Visually inspect ground-mount hardware, wiring runs, combiner box, and conduit; confirm production roughly matches expected output for current sun conditions

• Annually: Clean solar modules, tighten mechanical and electrical connections, and schedule a professional inspection to verify system performance, safety, and code compliance

Warranty

• Solar Panels: 30-year performance warranty (bifacial double-glass modules)

• Inverter & Battery: EG4 FlexBOSS21 inverter/charger and 48V EG4 Lithium Indoor Wall Battery are covered under EG4 manufacturer warranties (refer to EG4 FlexBOSS21 and battery spec sheets for full details)
