SGPWOSAY 5000W DC 48V UL1741 Pure Sine Wave Solar Inverter with 100A MPPT Charger

All-in-one power solution for off-grid and hybrid setups

The SGPWOSAY 5000W DC 48V solar inverter charger combines a true sine wave inverter, a 100A MPPT solar charger, and a 40A AC battery charger into a single rugged unit. Built around UL1741 compliance, it delivers clean, stable AC to household and office loads while efficiently harvesting energy from solar or grid sources. This integrated approach reduces component clutter and offers streamlined installation for flexible power management.

Designed to adapt to real-life living and work environments, it supports both solar-first and utility-first workflows. Whether used as a primary power source in a remote cabin or as a reliable backup in a home office, the system is engineered to handle changing energy needs with composure and clarity.

Key capabilities that matter in daily use

• All-in-one solar charge inverter: 5000W DC 48V inverter plus up to 100A of battery charging from solar and AC sources; supports PV arrays up to 5500W.
• Parallel expansion: connect up to 6 units for up to 30kW total output; 120V single phase, 120/240V split phase, and 208V 3-phase options with more units.
• Stable AC output: Pure Sine Wave at 110V, capable of powering common household and office loads with overload protection.
• Four charging modes and four output modes: AC Priority, Solar Priority, Only Solar, and Mains & Solar hybrid; output modes include PV priority and hybrid operation.
• Battery compatibility and controls: supports 48V AGM/Sealed, Gel, Flooded, Lithium chemistries plus a user mode for custom inputs; RS485 port for BMS communication.

Flexible charging, versatile outputs

The four output and four charging configurations enable adaptive energy management in varying scenarios. Choose solar-first during sunny periods, rely on mains when needed, or run a hybrid setup that blends sources to fit your usage patterns. The system’s architecture helps you balance continuous power with energy efficiency while staying within safe operating limits.

• PV priority keeps solar generation at the forefront when panels are producing surplus energy.
• Utility priority can ensure uninterrupted mains power during low solar hours.
• Inverter priority supports standalone operation when grid access is unavailable.
• Hybrid modes blend PV and mains to maintain steady power delivery to connected loads.

Battery types and connectability

With broad compatibility, the inverter accepts a range of 48V chemistries and provides an interface for BMS communication. This makes it easier to tailor energy storage to your preferred battery technology while keeping monitoring and protection features in view.

Real-world use cases and benefits

• Backups for homes and small offices, helping refrigerators, routers, and lighting stay powered during outages.
• Remote cabins or workshops where solar is the primary energy source but occasional grid access is useful.
• RVs or off-grid vacation homes where scalable power helps manage peaks from appliances and tools.

Note: The described capabilities are designed to offer flexibility and potential performance improvements under typical use cases. Results may vary with installation, battery selection, and environmental conditions.
