10KW Complete Offgrid Solar Kit + EG4 18kPV + 32KW OMO 48V Freedom Series Lithium Battery + 11KW Solar with Roof Mounting Rails and Wiring

The 10KW Complete Offgrid Solar Kit + EG4 18kPV + 32KW OMO 48V Freedom Series Lithium Battery + 11KW Solar with Roof Mounting Rails and Wiring is designed for those seeking a powerful, scalable, and roof-mounted off-grid energy system. Delivering up to 49,500 watts of solar production per day (based on 4.5 sun hours) and backed by a high-capacity 32kWh heated lithium battery, this kit is ideal for cabins, small to mid-sized homes, garages, RVs, and pole barns using around 1,400 kWh per month. The system is fully expandable for future panel or battery additions.

Specifications

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

• Inverter: 1× EG4 18kPV 48V split-phase hybrid inverter/charger

• Battery Bank: 1× OMO 32kWh 48V Freedom Series heated lithium battery with Bluetooth monitoring & LCD readout

• Mounting System: Complete IronRidge roof-mounting rail kit including rails, splices, legs, fasteners, and bolts

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

Features

• Bifacial Double-Glass Panels: Rear-side energy gain up to 25%, improved weak-light performance, 5400 Pa snow load, 2400 Pa wind load, and 30-year power warranty

• High-Capacity Lithium Battery: 32kWh heated lithium battery delivers robust off-grid storage with Bluetooth and LCD readout for real-time monitoring

• Off-Grid Compatibility: Suitable for cabins, RVs, garages, pole barns, and small homes. Runs wells, washing machines, fans, TVs, lights, refrigerators, freezers, electronics, and smaller AC systems

• Expandable System: All kits can be upgraded over time. Daily/monthly production estimates are based on ~4.5 peak sun hours (lower in Northeast, higher in Southwest)

• Hybrid Inverter Performance: EG4 18kPV supports flexible off-grid energy usage with split-phase output and efficient charging

• DIY-Friendly Installation: Homeowners with basic wiring knowledge can install the system. Roof-mount rails require the most labor—electricians may be consulted for final connections

Maintenance

• Daily: Monitor inverter and battery status; ensure panels remain unobstructed

• Weekly: Inspect wiring, roof-mount hardware, and compare actual production to expected sun-hour output

• Annually: Clean panels, tighten hardware, inspect combiner/grounding connections, and evaluate inverter/battery performance

Warranty

• Solar Panels: 30-year performance warranty

• Inverter & Battery: Covered under manufacturer warranties (see linked Freedom_Specs.pdf for battery details)
