High-yield 1.5kW pure sine inverter with 2500W PV array support, 80A MPPT charger, and single 12V battery operation for homes.
The Crown Micro Xavier 1.5KW (Model: X-1.5KW-PF1) is engineered for residential loads and small commercial workstations in areas facing routine grid instability and brownouts. Operating on a compact 12VDC battery architecture, this unit removes the high upfront cost of multi-battery banks while delivering a continuous 1500W pure sine wave AC output with a unity power factor (PF 1.0). Its primary technical asset is an oversized 2500W MPPT solar charger accepting up to 400VDC open-circuit voltage. This wide DC voltage window (30VDC to 400VDC) allows series wiring of modern high-wattage monocrystalline solar panels, ensuring early morning energization and high performance under cloudy weather conditions.
Zener Authenticity Promise: All sitemarks, models, and technical statistics are registered with the factory and verified in our physical laboratory before sale.
For maximum efficiency, connect at least three 550W panels in series to ensure open-circuit voltage stays consistently above 120VDC during high midday temperatures.
Use 25mm² pure copper DC battery cables and keep the wire run under 1.5 meters to prevent excessive DC voltage drop on 12V configurations.
Regularly clean the removable side dust filters every 60 days to keep internal heatsink temperatures low during humid summer conditions.
Install a 100A DC fuse or circuit breaker directly between the positive terminal of the 12V battery and the inverter's DC input terminal for short-circuit safety.
Yes, the Xavier 1.5KW features a battery-independent operational design that can power AC loads directly from solar panel arrays during daylight hours when PV output is sufficient.
It can power up to 1500W continuously, which handles a 150W refrigerator, 3 ceiling fans (225W), 6 LED lights (60W), 1 television (80W), and 1 desktop PC (200W) at the same time.
Yes, the unit includes configurable bulk and floating charge profiles that permit integration with 12.8V LiFePO4 batteries using user-defined parameters.
You can install up to 2500W of PV, which equals four or five 550W mono PERC or TOPCon solar panels wired in series.
No, the Xavier 1.5KW is a dedicated off-grid inverter designed for self-consumption and battery backup; it does not export excess solar electricity to the utility grid.
