SunGold Power 16kW 48V Off-Grid Solar Kit – 25.6kWh LiFePO4 Battery + 32 × 415W Panels (SGR-16K25E)

Build a serious off-grid system with the SunGold Power SGR-16K25E. This package pairs two 8kW 48V split-phase inverters (16kW total) with 32×415W monocrystalline panels (13.28kW array) and a 25.6kWh LiFePO4 battery bank (5 × 5.12kWh modules in a server rack). With around 4 peak-sun hours, the array can produce up to ~53kWh/day, enough for heavy household loads like AC units, well pumps, fridges, tools, and office equipment.

Each inverter includes MPPT solar charging, AC charging, generator input support, and Wi-Fi monitoring in a compact, transformer-free design. The system can parallel up to 6 inverters for future growth (single-phase 120V, split-phase 240V, or 208V three-phase). Durable panels and long-life LiFePO4 batteries keep operating costs low and uptime high.

Key Features

• 16kW Split-Phase Output – 2 × 8kW, 48V inverters deliver 120/240V pure sine power

• High-Yield Array – 32 × 415W mono panels (13.28kW) for strong daily production

• Deep Storage – 25.6kWh LiFePO4 (5 × 5.12kWh, rack-mounted) with long cycle life

• All-in-One Control – Built-in MPPTs, AC charger, generator input, and system protections

• Scalable System – Parallel up to 6 inverters; add panels or batteries as needs grow

• Ready to Install – Includes server rack, breakers, PV extension cables, and Z-brackets

FAQs

How much energy will I get daily?
With ~4 peak-sun hours, expect ~53kWh/day from the 13.28kW array (location, tilt, and weather will affect output).

Can I expand later?
Yes. You can parallel up to 6 inverters and add more panels and batteries within electrical/code limits.
