125KW Complete Offgrid Solar Kit + 7x 15K Sol-Ark Inverter + 32kWh OMO 48V Freedom Series Lithium Battery +125.4KW Solar with Ground Mount and Wiring

The 125KW Complete Offgrid Solar Kit + 7x 15K Sol-Ark Inverter + 32kWh OMO 48V Freedom Series Lithium Battery +125.4KW Solar with Ground Mount and Wiring is a powerful package designed for a complete off-grid home or high-demand property. The solar array will produce around 564,300 watts per day based on 4.5 hours of sun. This size of system generally works great for large sized homes, farms, and similar applications that use around 16,929 kWh per month. This system is built to be scaled up for future additions of panels or batteries. The included lithium battery bank is rated for 32 kW of storage power.

Features

• Bifacial Double-Glass Panels: These solar panels are bifacial with double glass. Bifacial technology enables additional energy harvesting from the rear of the panel (up to 25% more). They will produce more power output in weak light conditions, such as cloudy, hazy, or early morning conditions.

• High Wind & Snow Ratings: Panels offer high wind and snow resistance loads with 5400 PA snow load and 2400 PA wind load, and come with a 30-year power warranty.

• Ground-Mount System: Ground mount system is built based on a 3" pipe setup. Customer will source 3" sch 40 pipe locally; all other hardware is supplied.

• Large-System Capability: Designed for large size homes, farms, and high-usage off-grid properties that use around 16,929 kWh per month, with plenty of room to scale up with more panels or additional batteries.

• Sol-Ark 15K Inverter Output: 120/240V split phase output, usable in both grid-tied and off-grid applications, and can be used with or without batteries.

• Battery Compatibility: 48V battery backup input supports flooded lead acid or lithium batteries for flexible storage options.

• Integrated MPPT: Built-in MPPT charge controller with 3× MPPT inputs per Sol-Ark 15K inverter for efficient solar harvesting.

• Generator Support: Generator-compatible system for backup or supplemental power in low-sun conditions.

• Smart Monitoring & Control: LCD touch screen and WiFi connectivity provide easy control, configuration, and monitoring of system performance.

• High Efficiency & Outdoor Rating: DC transformerless design with 97.5% inverter efficiency and NEMA 3R rating for approved outdoor use.

• Scalable Inverter Architecture: Parallel stacking of up to 8 Sol-Ark 15K units for massive system expansion and redundancy.

• Fast Transfer Time: 4 ms transfer time from batteries to grid power for seamless power continuity.

Maintenance

• Daily: Monitor inverter status, battery levels, and solar production via the LCD screen or WiFi interface.

• Weekly: Visually inspect panels for dust, snow, or debris and ensure ground-mount and wiring remain secure.

• Annually: Inspect all AC and DC wiring, combiner boxes, mounting hardware, and grounding; perform a thorough cleaning of solar panels and verify inverter firmware/settings.

Warranty

• Sol-Ark 15K Inverters: 10-year manufacturer warranty.

• Solar Panels: 30-year power performance warranty.

• Battery System: Warranty coverage per OMO Freedom Series manufacturer specifications (see specification sheet).
