10KW Complete Offgrid Solar Kit + EG4 FlexBOSS21 + 32KW OMO 48V Freedom Series Lithium Battery + 11KW Solar with Roof Mounting Rails and Wiring

The 10KW Complete Offgrid Solar Kit with EG4 FlexBOSS21 & OMO Freedom Series Battery is a powerful and scalable off-grid solution for cabins, small to mid-sized homes, workshops, RV setups, and more. With a 32,000-watt usable lithium battery bank and an 11,000W bifacial solar array producing up to 49,500 watts per day (based on 4.5 hours of peak sunlight), this system supports households consuming around 1,400 kWh/month. The system is fully expandable, allowing future additions of panels or battery storage as energy needs grow.

Specifications

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

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

• Battery: 1 × OMO 32KW 48V Freedom Series heated lithium battery with Bluetooth and LCD display

• Roof Mount System: Complete IronRidge roof-mount rail set with splices, legs, fasteners, and bolts

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

Features

• Bifacial Solar Panels: Double-glass panels capture sunlight from both front and rear, delivering up to 25% more energy. Engineered for high performance in weak-light conditions and built with 5400 Pa snow load and 2400 Pa wind load ratings. Includes a 30-year power warranty.

• Suitable For: Small cabins, RVs, garages, pole barns, and off-grid homes requiring reliable power for wells, washing machines, fans, TVs, lighting, refrigerators, freezers, electronics, and small AC units.

• Energy Use Guidance: Average U.S. home use is 877 kWh/month. This system supports households using approx. 1,400 kWh/month and can be expanded anytime.

• Solar Output Estimates: Based on 4.5 daily peak-sun hours (Midwest average). Northeast receives slightly less; Southwest receives significantly more. Daily and monthly projections are calculated using these values.

• Documentation: Includes installation manual, EG4 FlexBOSS21 spec sheet, and OMO Freedom Series Battery Specification Sheet.

• Ease of Installation: Homeowners with basic wiring knowledge can install the system. Roof-mount racking typically requires the most labor. For those without wiring experience, a local electrician is recommended.

Maintenance

• Daily: Check inverter and battery status indicators; ensure panels are unobstructed.

• Weekly: Inspect wiring, mounting hardware, combiner box, and verify power production aligns with expected output.

• Annually: Perform full system cleaning, torque-check all hardware, wash panels, and inspect all electrical connections.

Warranty

• Solar Panels: 30-year performance warranty on bifacial modules.

• Electronics & Battery: EG4 FlexBOSS21 inverter and OMO 32KW Freedom Series lithium battery covered by manufacturer warranties (see included documentation).
