CrownMicro Xavier XAVIER-II-3.6KW PV-4500 – Overview
CrownMicro Xavier XAVIER-II-3.6KW PV-4500 is a 3.6kW pure sine wave, MPPT-based solar inverter designed for dependable home and SME power. It pairs a wide PV window (60–450VDC, 500V OCV) with a high-current, built-in 120A MPPT charger and selectable AC input ranges for PCs or household appliances. The inverter supports 24V Lithium or Lead-acid batteries and can also run without a battery when required. With PF=1, 93% peak efficiency and a fast 10ms transfer time (20ms for home appliances), it delivers stable, clean power to sensitive loads.
Key Benefits
- All-in-one hub: inverter + 120A MPPT + AC charger with clean, pure-sine output.
- Dual output: smart load management lets you split essential vs. non-essential circuits.
- Battery-independent design: operate from PV/AC today; add a 24V battery later for backup and time-of-use shifting.
- Wide PV window: 60–450VDC supports long strings and earlier start-up in low light.
- User-friendly: color display/touch UI, anti-dust design, USB/RS-232 (optional USB/dry contact), Wi-Fi ready.
For a complete system, pair CrownMicro Xavier XAVIER-II-3.6KW PV-4500 with quality solar panels and a right-sized 24V battery bank. Configure for self-consumption, backup power or shop/office loads using the integrated communications and dual-output logic.
