Sun Gold Power 6.5kW 48V Split Phase Solar Inverter 140A

Product Overview

The Sun Gold Power SPH6548P is a 6.5kW pure sine wave solar inverter that combines battery charging and dual MPPT solar controllers into one unit. It is built for 48V battery systems that need straightforward power conversion, flexible charging behavior, and clean AC output for everyday living. With split-phase 120V/240V or single-phase 120V output, it fits a wide range of off-grid and backup-style setups where you want stable power without juggling separate boxes for inverter and solar charging.

This unit includes a WiFi module for monitoring system status and key parameters through a mobile application. That is useful for both homeowners and installers because it makes it easier to keep an eye on performance, confirm charging behavior, and adjust settings without standing in front of the inverter. For sites that need more capacity later, it supports parallel connection of up to six units for increased power and surge capacity, with output options that include single-phase, split-phase, or three-phase.

It also supports multiple charging and output modes including hybrid, utility priority, solar priority, and inverter priority. That flexibility matters when you are trying to match the system to how the property actually uses energy. The time-slot charging and discharging function helps align charging behavior with local tariffs when the project includes utility interaction, and the maximum battery charging current of 140A supports faster battery charging when available input and battery specs allow it.

Key Features

• Supports parallel connection of up to six units for increased power and surge capacity, with single-phase, split-phase, or three-phase output options

• Installations requiring CAN and RS485 communication support

Why This One Makes Sense

This inverter keeps the core pieces together: pure sine wave AC output, dual MPPT solar control, and battery charging in a single unit. That simplifies system layout while still giving you meaningful control through multiple operating modes and time-slot charging and discharging. The 6.5kW rated output and 13,000VA peak power support demanding start-up events, and the 140A maximum charging current supports strong charging performance when conditions allow. Add parallel capability up to six units, split-phase or single-phase output options, and WiFi monitoring through a mobile app, and it fits systems that need to work reliably today while staying adaptable for tomorrow.
