Sungold Power - 6.5kW 48V Split Phase Solar Inverter Charger – SPH6548P | Parallel-Ready Hybrid Inverter

Description 

Sungold Power 6.5kW 48V Split Phase Solar Inverter Charger 

Power your home, cabin, RV, or off-grid system with the Sungold Power SPH6548P 6.5kW 48V Split Phase Solar Inverter Charger, a high-performance all-in-one hybrid inverter engineered for flexible solar, battery, and grid integration.

This advanced unit combines a 6.5kW pure sine wave inverter, dual high-efficiency MPPT solar charge controllers, and a high-capacity AC battery charger into one compact, scalable solution. With support for 120V/240V split-phase or 120V single-phase output, it is ideal for residential loads, backup power systems, RVs, and off-grid solar installations.

High Solar Input & Fast Charging

The SPH6548P features two built-in MPPT solar controllers with support for up to 550VDC open-circuit PV input and a maximum combined battery charging current of 140A, enabling faster charging and efficient energy harvesting from large solar arrays.

Parallel-Ready & Scalable Power

Designed for system expansion, this inverter supports parallel operation of up to six units, delivering up to 39kW of total output power. Parallel configurations support:

• 120V single-phase

• 120V/240V split-phase

• 208V three-phase (with more than three units)

This makes the SPH6548P suitable for growing residential systems, workshops, and light commercial applications.

Smart Energy Management

Multiple intelligent charging and output modes allow you to customize how power flows through your system:

Charging Modes:

• Hybrid Charging

• Utility Priority Charging

• Solar Priority Charging

• Solar-Only Charging

Output Modes:

• Utility Priority

• Solar & Utility Hybrid

• Solar Priority

• Inverter Priority

The built-in time-slot charging and discharging function lets you schedule charging and battery usage based on local peak and off-peak utility rates, maximizing savings and solar self-consumption.

Wide Battery Compatibility

Compatible with 48V lithium (LiFePO₄), AGM, gel, sealed, and flooded lead-acid batteries, the SPH6548P also includes a user-defined battery mode for custom configurations. It supports battery-free operation, and when lithium batteries are dormant, utility power or solar PV can automatically activate them.

For seamless integration, the inverter supports CAN and RS485 communication with Sungold Power lithium batteries.

Built-In Monitoring & Protection

A built-in WiFi module enables real-time monitoring and system control via a mobile app. Comprehensive protection systems safeguard against:

• PV input over-voltage & over-current

• AC input over-voltage

• Battery over-voltage

• Overload & short circuit

• Over-temperature

With a rated output of 6,500W and peak surge capacity of 13,000VA, the SPH6548P delivers stable, reliable power even during high startup loads.

Certified & Reliable

The SPH6548P is UL 1741 certified for off-grid systems, ensuring safety, compliance, and long-term reliability for residential and off-grid applications.
