Description

SunGoldPower 20KW 48V Split Phase Solar Inverter (2 Units Parallel)

The SunGoldPower 20 kW 48 V Split Phase Solar Inverter (2 Units Parallel) is a powerful and scalable off-grid and hybrid solar inverter solution designed to meet the energy needs of larger homes, commercial buildings, workshops, and remote installations. This system pairs two 10 kW pure sine wave inverters in a parallel configuration to deliver a combined continuous output of 20 kW, providing clean, reliable 120 V/240 V split-phase AC power suitable for heavy loads and whole-home usage.

Each inverter includes dual high-current MPPT solar charge controllers — allowing you to harvest up to 11,000 W of solar power per unit — and features intelligent energy management that optimizes solar harvesting, battery charging, and mains or generator integration. This flexibility makes the system well suited for off-grid sites, hybrid solar-plus-storage setups, and backup power systems where reliability and efficiency are key.

Pre-configured for parallel operation, the inverter pair can be easily expanded — supporting up to six units in parallel for a total of 60 kW — giving you room to grow your power system as demand increases. Optional Wi-Fi monitoring and rich communication interfaces (RS485, CAN, USB) provide real-time performance data and remote system diagnostics, empowering you to oversee your energy system with confidence.

With built-in safety and protection features and a fast automatic transfer switch (UPS) that switches in under 10 ms, this SunGoldPower inverter system is designed to keep critical equipment and loads powered even during grid interruptions — making it a robust choice for essential home and business applications.
