FAQ
Questions, answered
Can’t find what you need? Call our toll-free line 1800 120 1278.
What does a hybrid inverter do?
It manages solar, battery and grid together: powering your home from solar, storing surplus in a battery and switching to backup when the grid fails.
How fast does backup switch on?
The EPS output takes over in under 4 ms, so most appliances keep running without interruption.
Which batteries can I use?
Lithium and lead-acid batteries in the 40–60 V range. The Xwatt XWB-5.12KWH low-voltage battery is a direct match.
Which model sizes are available?
Five models from 3.0 kW to 6.0 kW (XWH-3.0K-LV to XWH-6.0K-LV), with PV arrays up to 9000 Wp.
Can I monitor it remotely?
Yes, through the XMonitor app over Wi-Fi, GPRS or local mode, with USB / RS485 interfaces.
What warranty is included?
Every hybrid inverter carries a 5-year warranty.
