SGPWOSAY 3000W Pure Sine Wave Inverter Charger 24V — 80A MPPT Solar + 40A AC Charger, UPS Transfer

SGPWOSAY 3000W DC 24V pure sine wave inverter charger combines solar MPPT charging, an AC battery charger and a UPS-style inverter for reliable, multi-source power management.

This upgraded SunGoldPowerCo.,Ltd inverter integrates a high-efficiency 80A MPPT solar charger (MPPT input 120–400Vdc), a 40A AC battery charger and a 3000W pure sine wave inverter in one compact unit. Designed for off-grid systems, backup power and hybrid installations, it supports multiple charging priorities and battery chemistries while offering fast automatic transfer to keep sensitive electronics running without interruption. The unit’s LCD/LED display and optional remote monitoring (WiFi/GPRS extra) make system oversight straightforward for homeowners, RV users and small commercial sites.

How does this inverter prioritize power between solar, grid and battery?

The SGPWOSAY unit provides selectable charging modes so you can choose the best energy source mix for your situation. Modes include AC Priority, Solar Priority, Only Solar and a Mains & Solar hybrid mode that balances inputs to maximize uptime and battery health.

• AC Priority — grid power used first; solar supplements and charges battery.
• Solar Priority — solar used first; grid engages only when solar is insufficient.
• Only Solar — isolates grid; solar and battery handle loads when available.
• Mains & Solar hybrid — simultaneous use to meet higher loads and speed charging.

What battery types and management features are supported?

The inverter supports common 24V battery chemistries and includes a configurable user mode for custom charging parameters. Built-in charging algorithms permit safe charging of sealed lead-acid, AGM, gel, flooded and lithium batteries, with selectable charge current and voltage profiles.

• Compatible with 24V AGM, sealed, gel, flooded and lithium batteries.
• User Mode allows custom charge settings for nonstandard batteries.
• 40A AC charger plus 80A MPPT solar charging to reduce charge time.
• Lithium support with appropriate settings for safe cycle life.

How quickly will the inverter switch to battery power during an outage?

This inverter provides near-instantaneous transfer to battery supply so connected equipment stays powered. The transfer time is fast enough for most electronics and prevents shutdowns of computers, routers and critical appliances in typical home or small-business environments.

• Automatic transfer to inverter supply in approximately 10 milliseconds.
• Uninterruptible power suitable for sensitive electronics and network gear.
• Three selectable output modes: mains priority, PV priority and inverter output.
• LCD/LED display shows real-time system status during transfer events.

What monitoring and warranty support come with the unit?

The inverter includes a dynamic LCD/LED display for on-site diagnostics and system state. Optional WiFi/GPRS remote monitoring (sold separately) allows real-time data and alerts through cloud services. SGPWOSAY and SunGoldPowerCo.,Ltd back the device with technical support and a 24-month warranty.

• Onboard LCD/LED displays voltage, current, power and operating mode.
• Optional WiFi/GPRS remote monitoring for off-site oversight (extra cost).
• 24-month warranty and lifetime technical support from the manufacturer.
• Manufactured by SunGoldPowerCo.,Ltd with over 10 years in inverter production.

Who is this for: The SGPWOSAY 3000W 24V pure sine wave inverter charger suits homeowners adding solar-backed backup, RV or boat owners needing integrated charging and inverter capability, and small commercial users who require a compact hybrid solution. It's ideal where flexible charging options, rapid transfer to battery power and multi-chemistry battery support are required. Choose this unit when you want a single, managed device to combine MPPT solar charging, AC charging and UPS-level inverter performance in medium-power systems.
