This 4kW hybrid solar inverter converts raw photovoltaic energy into clean, pure sine wave power for the loads that matter: refrigerators, pumps, tools, and electronics. With a 98% peak conversion efficiency, it wastes almost nothing of what your panels harvest, making every watt of solar capacity count twice.\u003c\/p\u003e\n\u003cp\u003eAt its heart is a 100A MPPT charge controller with a 60-500VDC operating window, which means it can harvest energy from high-voltage solar arrays that smaller controllers cannot even see. The hybrid architecture lets it work in both off-grid and grid-tie modes, switching intelligently between solar, battery, and utility power so your loads never notice the seam. It will even run your loads without a battery attached, feeding solar directly to the appliances during daylight hours.\u003c\/p\u003e\n\u003cp\u003eCommunication is where this inverter stops being a box and becomes part of your nervous system. RS232, RS485, and built-in WiFi interfaces stream live generation, consumption, and battery telemetry to your phone, so you can watch your system earn its keep in real time. With CE certification and support for automatic lithium battery activation, The Sun Bridge is the control center that turns scattered panels into a unified power plant.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003chr style=\"margin:20px 0;border:0;border-top:1px solid #eee;\"\u003e\n\u003cdiv class=\"product-features\"\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul style=\"list-style:none;padding:0;\"\u003e\n\u003cli\u003e✦ 4,000W rated output with pure sine wave: clean, appliance-safe power for inductive loads like fridges, pumps, and motors.\u003c\/li\u003e\n\u003cli\u003e✦ 100A MPPT solar charger with 60-500VDC range: harvests from high-voltage arrays with up to 98% conversion efficiency.\u003c\/li\u003e\n\u003cli\u003e✦ Hybrid off-grid \/ grid-tie operation: automatically blends solar, battery, and utility power without interrupting your loads.\u003c\/li\u003e\n\u003cli\u003e✦ Battery-free operation supported: runs loads directly from solar during daylight, ideal for temporary or budget setups.\u003c\/li\u003e\n\u003cli\u003e✦ WiFi \/ RS232 \/ RS485 monitoring: real-time system telemetry on your phone, including generation, load, and battery state.\u003c\/li\u003e\n\u003cli\u003e✦ Automatic lithium battery activation: wakes dormant LiFePO4 packs so the system recovers from deep protection events on its own.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-specs\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul style=\"list-style:none;padding:0;\"\u003e\n\u003cli style=\"padding:8px 0;border-bottom:1px solid #e8e8e8;\"\u003e\n\u003cstrong style=\"color:#1a1a1a;\"\u003eRated Power:\u003c\/strong\u003e 4,000W (4kW) pure sine wave\u003c\/li\u003e\n\u003cli style=\"padding:8px 0;border-bottom:1px solid #e8e8e8;\"\u003e\n\u003cstrong style=\"color:#1a1a1a;\"\u003eMPPT Voltage Range:\u003c\/strong\u003e 60-500VDC\u003c\/li\u003e\n\u003cli style=\"padding:8px 0;border-bottom:1px solid #e8e8e8;\"\u003e\n\u003cstrong style=\"color:#1a1a1a;\"\u003eMaximum PV Array Power:\u003c\/strong\u003e 4,500W\u003c\/li\u003e\n\u003cli style=\"padding:8px 0;border-bottom:1px solid #e8e8e8;\"\u003e\n\u003cstrong style=\"color:#1a1a1a;\"\u003eMaximum Solar Charge Current:\u003c\/strong\u003e 100A \/ 120A\u003c\/li\u003e\n\u003cli style=\"padding:8px 0;border-bottom:1px solid #e8e8e8;\"\u003e\n\u003cstrong style=\"color:#1a1a1a;\"\u003eMaximum PV Open-Circuit Voltage:\u003c\/strong\u003e 500VDC\u003c\/li\u003e\n\u003cli style=\"padding:8px 0;border-bottom:1px solid #e8e8e8;\"\u003e\n\u003cstrong style=\"color:#1a1a1a;\"\u003ePeak Efficiency:\u003c\/strong\u003e 98%\u003c\/li\u003e\n\u003cli style=\"padding:8px 0;border-bottom:1px solid #e8e8e8;\"\u003e\n\u003cstrong style=\"color:#1a1a1a;\"\u003eCommunication:\u003c\/strong\u003e WiFi \/ RS232 \/ RS485\u003c\/li\u003e\n\u003cli style=\"padding:8px 0;border-bottom:1px solid #e8e8e8;\"\u003e\n\u003cstrong style=\"color:#1a1a1a;\"\u003eOperating Humidity:\u003c\/strong\u003e 5% -
