SGPWATT 5000W Hybrid Solar Inverter 48V — 80A MPPT, 40A AC Charger, Pure Sine (UL1741)

SUNGOLDPOWER's SPH504880A is a 5000W, 48V all‑in‑one hybrid solar inverter and charger that converts DC from a PV array or battery into 110/120V pure sine AC while offering up to 80A MPPT solar charging and 40A AC battery charging for off‑grid 48V systems.

This inverter is designed for off‑grid homes, cabins, RV installations and small commercial setups that require a reliable pure sine wave AC source plus flexible charging options. It’s UL1741 listed by ETL and built to manage combined solar and utility charging with fast automatic switchover, multiple output modes and broad battery compatibility. Note: the unit does not support parallel operation.

How does the inverter keep power flowing during outages?

The SPH504880A includes an uninterruptible power supply capability that switches to battery power in under 10 milliseconds when grid or generator power is lost. This near‑instant transition prevents most electronics from resetting and reduces downtime for critical appliances.

• Automatic transfer time: < 10 ms to avoid equipment shutdowns
• Pure sine wave output suitable for sensitive electronics
• Multiple output modes to prioritize inverter or grid as needed

What charging and output configurations are available?

The inverter supports four charging strategies (AC priority, Solar priority, Solar only, and Hybrid mains+solar) and four output modes (PV priority, utility priority, inverter priority, hybrid). This flexibility lets you optimize battery charging and power flow based on weather, grid status, and load demands.

• Max 80A MPPT solar charging and up to 40A AC battery charging
• Hybrid mode combines mains and PV for faster charging
• User mode allows custom charge parameters for specific battery chemistries

Which batteries and loads can this inverter support?

Designed for 48V systems, the SUNGOLDPOWER inverter works with sealed, gel, flooded, AGM and lithium batteries, with charging voltage range from 40–60V. It delivers a continuous 5000W AC output with a motor starting capability around 4 HP, making it suitable for heavy household appliances.

• Continuous output: 5000W pure sine AC (110/120V)
• High starting capability for motors and compressors (≈4 HP)
• RS485 port for BMS communication and user‑defined battery settings

How does the solar input and PV array specification affect installation?

The inverter accepts a PV array up to about 5500W with a maximum PV voltage around 500V, feeding its 80A MPPT charge controller. Proper array design and wiring are important to maximize solar charge current while staying within the inverter's voltage limits.

• Max PV power: ~5500W with max PV input voltage near 500V
• Built‑in MPPT improves harvest across changing sun conditions
• Follow local code and array wiring guidelines for safe installation

Who is this for? The SUNGOLDPOWER SPH504880A is aimed at homeowners, off‑grid builders, tiny‑house owners, and small commercial operators who need a robust, UL1741‑listed hybrid inverter with strong solar charging, reliable UPS behavior, and flexible battery compatibility. It’s a good match when you require a single, integrated device to manage PV charging, grid/generator charging and pure sine AC output without parallel expansion.
