125KW Complete Offgrid Solar Kit + 7x 15K Sol-Ark Inverter +125.4KW Solar with Ground Mount and Wiring

The 125KW Complete Offgrid Solar Kit + 7x 15K Sol-Ark Inverter +125.4KW Solar with Ground Mount and Wiring is designed for large off-grid homes, farms, and high-demand properties that use around 16,929 kWh per month. The solar array produces approximately 564,300 watts per day based on 4.5 peak sun hours. This kit is engineered for scalability, allowing future expansion with additional panels or batteries. It can operate without any batteries connected, and a 48V battery bank can be added to the Sol-Ark inverters at any time for enhanced storage and backup capability.

Features

• High-Output Off-Grid System: Approximately 564,300W of daily solar production (at 4.5 peak sun hours) for large homes, farms, and high-load applications using around 16,929 kWh per month.

• Battery-Optional Operation: Kit can run without batteries. A 48V battery bank can be added later for backup or load shifting.

• Bifacial Double-Glass Panels: Bifacial technology harvests energy from both front and rear surfaces, providing up to 25% more production, especially in reflective or diffuse light environments.

• All-Weather Durability: Panels are rated for 5400 PA snow load and 2400 PA wind load, ensuring long-term reliability in harsh climates and backed by a 30-year power warranty.

• Sol-Ark 15K Inverter Output: Provides 120/240V split-phase power suitable for whole-home or farm distribution, tools, wells, HVAC, and other common loads.

• Grid-Tie or Off-Grid Flexibility: Can be configured as grid-tied, off-grid, or hybrid with generator support and battery backup.

• Integrated MPPT: Each Sol-Ark 15K includes a built-in MPPT charge controller with 3× MPPT inputs for flexible string design and optimized solar harvest.

• Smart Monitoring & Control: LCD touchscreen interface and WiFi connectivity provide real-time system monitoring and configuration.

• High Efficiency Design: Transformerless inverter architecture with up to 97.5% efficiency, maximizing energy yield.

• Outdoor-Rated Inverters: NEMA 3R enclosures are approved for outdoor installation to simplify layout and save indoor space.

• Scalable Architecture: Parallel stacking of up to 8 Sol-Ark units allows future expansion beyond the base 7-inverter configuration.

• Fast Transfer Time: Approximately 4 ms transfer from batteries to grid power for near-seamless backup operation (when batteries are added).

• Installation Option: Professional installation is available. Customers should contact the seller prior to ordering for custom installation pricing by region.

Maintenance

• Daily: Check the Sol-Ark inverter display or WiFi app for system status, production, and any active alerts.

• Weekly: Visually inspect ground-mount arrays for debris, soiling, snow buildup, or shading and clear as needed to maintain optimal performance.

• Monthly: Walk the array and equipment area to verify that conduit, wiring, and combiner boxes are secure and undamaged.

• Annually: Have a qualified technician inspect all electrical connections, torque-check terminals, review inverter logs, verify ground lugs, and clean panel surfaces more thoroughly if required.

• As Needed: Coordinate with a licensed installer if adding batteries, expanding the array, or reconfiguring the system for different operating modes (grid-tied, hybrid, or full off-grid).

Warranty

• Solar Panels: 30-year power output warranty

• Sol-Ark Inverters: 10-year manufacturer warranty

• Mounting & BOS Components: Warranties vary by manufacturer; see included documentation for specific terms.
