Description

18,000W 48V Split Phase Pure Sine Wave Inverter Charger

Heavy-Duty Off-Grid & Whole-Home Backup Power Solution

The SunGold Power 18,000W 48V Split Phase Pure Sine Wave Inverter Charger is a high-capacity, low-frequency inverter engineered for demanding residential, commercial, and off-grid power systems. Designed to deliver reliable 120V/240V split-phase output, this all-in-one unit combines a powerful inverter, intelligent battery charger, and automatic transfer switch into a single, efficient system.

Built for large electrical loads and surge-heavy appliances, the 18kW inverter provides clean, stable pure sine wave power ideal for whole-home backup, cabins, workshops, farms, and business applications. With fast transfer times and flexible AC/battery priority settings, it ensures uninterrupted power during grid outages or generator transitions.

Why Choose the 18,000W System?

Compared to the 12kW and 15kW models, the 18kW inverter offers higher continuous output, stronger surge capacity, and improved performance for large homes and businesses—without changing your battery bundle configuration. It’s ideal when you need maximum power headroom while keeping a modular, scalable battery system.
