10KW Complete Offgrid Solar Kit - 15K Sol-Ark Inverter + 20.48KW OMO Stack Lithium Battery +11KW Solar with Ground Mount and Wiring

The 10KW Complete Offgrid Solar Kit - 15K Sol-Ark Inverter + 20.48KW OMO Stack Lithium Battery +11KW Solar with Ground Mount and Wiring is a complete off-grid power solution designed for small homes, cabins, RVs, garages, and pole barns. Delivering 20,480 watts of usable battery energy and up to 49,500 watts of solar production per day (based on 4.5 hours of sun), this package is ideal for properties using around 1,400 kWh per month and is engineered to be easily expanded with additional panels or batteries over time.

Specifications

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

• Inverter: 1 × Sol-Ark 15K-2P-N split-phase inverter, grid-tied compatible with generator input support

• Battery System: 4 × OMO 51.2V 5.12kW stackable heated lithium batteries with Bluetooth (20.48kWh total) + OMO stackable combiner with LCD + OMO wheeled base unit

• Mounting Hardware: Complete IronRidge ground-mount kit with rails, top caps, rail connectors, fasteners, and bolts (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 output/input/generator cabling, 20' 2/0 AC main line, wire gutter boxes, MC4 crimper tool set, and installation manual

Features

• High-Output Bifacial Panels: Double-glass bifacial design captures up to 25% additional rear-side energy and delivers stronger performance in cloudy, hazy, or low-light conditions.

• Rugged Construction: Panels are rated for 5400 Pa snow load and 2400 Pa wind load, making them suitable for harsh climates and long-term outdoor exposure.

• Sol-Ark 15K Inverter Performance: 120/240V split phase, usable with or without batteries, 48V battery input, 9kW continuous / 16kW surge (10 seconds), built-in 3 × MPPT charge controllers, generator support, LCD touchscreen, WiFi connectivity, and 97.5% inverter efficiency.

• Expandable System Design: Parallel stacking of up to 8 Sol-Ark inverters with modular OMO stackable batteries allows future expansion of storage and power as your needs grow.

• Appliance Support: Sized to run typical household loads such as a well pump, washing machine, fans, TVs, lights, refrigerator, freezer, computers, tablets, phones, and smaller air conditioning systems.

• Usage & Sizing Guidance: Designed around the U.S. average usage of ~877 kWh/month, this kit supports homes using around 1,400 kWh/month with room to expand the array or battery bank as needed.

Maintenance

• Daily: Visually check inverter and battery status indicators and ensure ground-mounted panels remain clear of debris or shading.

• Weekly: Inspect exposed wiring, conduit, combiner boxes, and ground-mount hardware for damage or loosened components; review production numbers against expected output.

• Annually: Perform a full system check including cleaning all panels, torque-checking rail and mount fasteners, and having a qualified electrician inspect all AC/DC connections—especially in high-wind or heavy-snow regions.

Warranty

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

• Inverter & Batteries: Sol-Ark 15K inverter carries a 10-year warranty; OMO stack batteries and combiner components include manufacturer-backed warranties as specified in accompanying documentation.
