4000W 48V Split Phase Pure Sine Wave Inverter Charger – UL1741 Certified | Off-Grid & Backup Power Solution
The SunGoldPower LFP 4000 Watt 48V Split Phase Inverter Charger is a high-performance power solution designed to meet the demands of small homes, RVs, trailers, boats, and businesses. Delivering a pure sine wave output, it ensures stable and safe electricity for all your appliances, including sensitive electronics.
Its split-phase capability provides both 120V and 240V output, making it ideal for systems with a 220V panel. This unit supports both 50Hz and 60Hz output frequencies, giving users flexible configuration options depending on their region or setup requirements.
This inverter charger combines three essential functions in one compact unit: a powerful inverter, a 40A smart battery charger, and a 10ms automatic transfer switch. It not only converts 48V DC battery power into AC electricity but also charges your batteries using grid or generator input when available. During outages, the transfer switch seamlessly shifts your power source from shore to battery within milliseconds, ensuring uninterrupted energy flow. UL1741 certification guarantees safety, reliability, and compliance with national standards.
The SunGoldPower 4000W Inverter Charger features two easy-to-use working modes. In Battery Priority Mode, the inverter uses battery power first, switching to AC only when the battery gets low—ideal for off-grid systems. In AC Priority Mode, it uses grid or generator power first and charges the battery at the same time. If AC power goes out, it automatically switches to battery power. These smart modes give you reliable, flexible power for any setup.
