The Crown Micro Xavier 4 kW is a hybrid solar inverter that integrates an inverter, MPPT solar charger, and battery charger in a single compact package. Built for residential and small commercial solar systems, it offers reliable power conversion with pure sine wave output and flexible charging priorities.
Crown Micro Xavier 4 kW Users can configure whether the inverter prioritizes solar or AC charging via the LCD panel. The device supports a configurable AC-input voltage range (to suit either home appliances or personal computers), and also provides cold-start capability (i.e., it can power on from the battery without grid). Communication ports for BMS (RS‑485, CAN‑BUS, RS‑232), onboard Wi-Fi for monitoring, and LCD + touch control make it highly user-friendly. Crown Micro Xavier 4 k also features protections against overload, over-temperature, and short-circuit, ensuring safety and reliability.
