10KW Complete Offgrid Solar Kit - 15K Sol-Ark Inverter + 15.36KW OMO Stack Lithium Battery +11KW Solar with Ground Mount and Wiring

The 10KW Complete Offgrid Solar Kit - 15K Sol-Ark Inverter + 15.36KW OMO Stack Lithium Battery +11KW Solar with Ground Mount and Wiring is a powerful, scalable solution for complete off-grid living. With a 15,360-watt usable lithium battery bank and an 11,000W bifacial solar array capable of producing around 49,500 watts per day (based on 4.5 peak sun hours), this kit is ideal for cabins, small to mid-sized homes, garages, RV setups, and more that use approximately 1,400 kWh per month. Designed for future expansion, the system allows easy addition of solar panels or batteries as your energy needs grow.

Specifications

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

• Inverter: 1 × Sol-Ark 15K-2P-N split-phase inverter (120/240V), grid-tie and generator compatible

• Battery Bank: 3 × OMO 51.2V 5.12kW stackable heated lithium batteries with Bluetooth (15.36 kWh total) + OMO stackable combiner with LCD readout and wheeled base unit

• Ground Mount System: Complete IronRidge ground-mount rail set with top caps, rail connectors, fasteners, and bolts (built around 3" schedule 40 pipe, sourced locally by customer)

• Included Components: Solar PV combiner box, AC combiner box kit (for 2+ Sol-Ark units), 500' 10AWG MC4 solar array cabling, 100' 6AWG AC input/output/generator cabling, 20' 2/0 AC main line, wire gutter boxes, MC4 crimper tool set, and installation manual

Features

• High-Efficiency Bifacial Panels: Double-glass bifacial design harvests light from both front and rear surfaces, delivering up to 25% more energy and excellent performance in weak-light conditions such as cloudy, hazy, or early-morning conditions.

• Rugged & Weather-Ready: Panels are rated for 5400 Pa snow load and 2400 Pa wind load, providing robust reliability in harsh climates and long-term outdoor performance.

• Sol-Ark 15K Inverter Performance: 120/240V split-phase output, works with or without batteries, 48V battery input (flooded lead-acid or lithium), 9kW continuous output with 16kW surge for 10 seconds, built-in 3× MPPT charge controllers, generator support, LCD touchscreen, Wi-Fi connectivity, and 97.5% efficiency in a NEMA 3R outdoor-rated enclosure.

• Expandable Power: Parallel stacking of up to 8 Sol-Ark units, plus modular OMO stack batteries, lets you grow capacity and power output as your home or off-grid project expands.

• Real-World Use Cases: Designed to run most common household loads including wells, washing machines, fans, TVs, lighting, refrigerators, freezers, computers, tablets, phones, and smaller AC systems in off-grid homes, cabins, RVs, garages, and pole barns.

• System Sizing Guidance: Average U.S. home usage is ~877 kWh/month. This kit is designed around ~1,400 kWh/month consumption and is fully expandable so you can add more panels or batteries over time.

Maintenance

• Daily: Verify inverter and battery status on the LCD/monitoring app and ensure solar panels are free from heavy debris or shading.

• Weekly: Visually inspect wiring, ground-mount structure, combiner boxes, and AC connections; compare actual production to expected values based on ~4.5 peak sun hours.

• Annually: Clean panels thoroughly, torque-check rail and structural hardware, inspect all battery and inverter terminations, and have a qualified electrician review the system if needed—especially for high-wind or heavy-snow regions.

Warranty

• Solar Panels: 30-year power warranty on bifacial double-glass modules for long-term energy production.

• Inverter & Battery: Sol-Ark 15K inverter includes a 10-year warranty; OMO stackable batteries and combiner are covered by manufacturer warranties as detailed in the included installation and product documentation.
