5000W 48V Solar Charger Inverter - SPH5048P (Parallel, 100A MPPT)
5000W 48V Solar Charger Inverter
A powerful all-in-one 48V inverter/charger for off-grid solar, backup power, RVs, cabins, workshops, and whole-home energy systems. It combines pure sine wave AC output, high-voltage solar charging, utility charging, and configurable operating modes in one system-ready unit.
All-in-one solar power control
Built for serious 48V solar systems
This SunGoldPower inverter is designed to sit at the center of an off-grid or hybrid solar setup. It can accept solar and AC charging, deliver pure sine wave AC output, communicate with compatible lithium battery systems, and support multiple operating modes so the system can be tuned around solar priority, utility priority, inverter priority, or hybrid output.
Choose the right model
Parallel-ready or single-unit design
SunGoldPower offers two versions of this 5000W 48V solar charger inverter. The SPH5048P is the higher-charge-current model and is designed for parallel-capable system expansion. The SPH504880A is the 80A MPPT version for single-inverter setups where parallel operation is not needed.
100A MPPT + parallel support
Best for larger solar builds where future expansion matters. The SPH5048P supports up to 6 units in parallel for increased output capacity.
80A MPPT single-unit option
Best for straightforward 48V systems that need a capable 5000W inverter/charger without parallel expansion.
Backup-ready operation
Configurable charging and output modes
Dial the system around how you actually use power. Run solar-first when you want to maximize PV production, let utility power support the system when needed, or configure inverter priority for battery-based operation.
Solar-first charging options
Use solar as the primary charging source or combine solar with AC charging depending on site conditions and battery needs.
Utility-supported backup
Keep loads running with grid/utility support when solar production is low or battery voltage reaches your configured limits.
Flexible output behavior
Configure PV priority, utility priority, inverter priority, or hybrid output so the system behaves the way your home, RV, or off-grid setup needs it to.
48V battery compatibility
Works with multiple battery chemistries
Build around the 48V battery bank that fits your system. This inverter supports common lead-acid and lithium battery types, including custom user settings for systems that need manual voltage configuration.
- 48V LiFePO₄ and lithium battery support.
- AGM/sealed, gel, and flooded battery compatibility.
- User-defined battery mode for custom charge parameters.
- RS485 communication support for compatible lithium battery BMS setups.
Expansion and applications
From cabins and RVs to larger home backup builds
Use it as the heart of a 48V solar power system for backup loads, off-grid living, RV power, workshops, and property systems where solar, battery storage, and AC power need to work together.
Backup power for priority loads
Pair with a properly sized 48V battery bank and solar array to support refrigerators, computers, lighting, electronics, and other essential loads.
Solar power for remote setups
Use solar charging and inverter output for cabins, sheds, RVs, mobile work setups, and off-grid properties.
Parallel-ready expansion with SPH5048P
The SPH5048P can be paralleled up to 6 units for larger single-phase, split-phase, or three-phase builds when installed correctly.
Monitoring and controls
Easy system visibility from the unit
The front display and control keys make it easier to view inverter status, battery information, and operating behavior. Optional Wi-Fi monitoring support may be available depending on the selected setup and accessories.
- LCD display for system information and operating status.
- Indicator lights and function keys for quick checks.
- RS485 communication support for compatible battery systems.
- Optional Wi-Fi module support where applicable.
