Pure Sine Wave Off-Grid Inverter Multi‑Unit Parallel Expansion Function, Single‑Phase Three‑Phase Split‑Phase Compatibility

【High‑Efficiency Conversion】This unit provides stable 5500W pure sine‑wave output, converting 48V DC into usable AC power for daily loads. The integrated charge controller combines inversion, solar charging and battery charging in one compact device. It optimizes solar panel energy collection, lowers conversion power loss, and delivers dependable full‑cycle energy management for off‑grid power supply systems. 【Wide Parameter Compatibility】It fits diverse solar installation needs with well‑matched electrical specs. Max PV input power reaches 5500W, DC voltage ranges 120‑500V, and combined solar‑AC charging current hits 120A. Measuring 536x352x135 mm with net weight 10.5 kg, this compact unit flexibly pairs with various solar panels and battery packs for different system configurations. 【Smart Remote Monitoring】An onboard LCD screen displays real‑time voltage, current and working status for local quick checks. Built‑in Wi‑Fi supports remote monitoring and parameter adjustment via phones or computers. Users can review power generation, battery level and load consumption remotely, adjusting modes without on‑site access and simplifying routine system maintenance. 【Comprehensive Safety Design】Multiple built‑in protections cover power failure, overload, over‑current, lightning, low‑voltage and short‑circuit risks. It triggers rapid cutoff under anomalies to protect batteries and connected appliances. The durable aluminum‑alloy housing improves heat dissipation during long‑time high‑load running, preventing overheating faults and prolonging internal component service life. 【Flexible Application Scenarios】Suitable for home backup power, off‑grid solar systems, RV and marine power supplies. It reliably runs kitchen appliances, lighting and office electronics. Multi‑unit parallel function supports single‑phase, three‑phase and split‑phase expansion, meeting requirements for small‑scale individual use as well as high‑capacity combined power supply projects.
