Sungold Power 20kW Off-Grid Solar Kit (120/240V Split-Phase, 48V)
32×450W Bifacial Solar Panels + Choice of Battery Storage (Standard / Heated / Outdoor)
If you’re building a serious off-grid home or backup power system, this is the complete high-capacity kit designed for real household loads. Sungold’s 20kW split-phase system delivers powerful 120/240V output, a massive solar array, and three battery options so you can choose the right setup for your climate, install location, and runtime goals.
This kit is ideal for powering essential home circuits, high-demand appliances, workshops, and remote properties—while giving you the flexibility to expand over time.
True 120/240V Power for Whole-Home Loads
This system includes two 10,000W 48V inverters (20,000W total) with 120/240V split-phase power, making it compatible with common residential circuits and higher-demand appliances.
Great for running:
-
Refrigerators & freezers
-
Well pumps & pressure systems
-
Laundry appliances
-
Kitchen circuits and household essentials
-
Power tools, equipment, and workshops
-
Electronics, office loads, and lighting
(As with any off-grid system, runtime depends on total wattage, surge loads, and energy habits.)
High-Output Solar Array (14.4kW Total)
Included are 32 × 450W bifacial N-Type monocrystalline solar panels, delivering a 14.4kW solar array designed to capture strong daily production and recharge your battery storage efficiently.
Bifacial technology can capture additional energy from reflected light in bright conditions—helping boost overall output.
Built to Expand as Your Needs Grow
This system is designed for long-term scalability. The inverters support parallel expansion up to 6 units, allowing future growth for larger homes, multi-building setups, or increasing power demands.
