FAQ

Questions, answered

Can’t find what you need? Call our toll-free line 1800 120 1278.

Which system sizes does the single phase range cover?

Ten models from 1.5 kW to 6.0 kW rated AC output (XW-1.5K to XW-6.0K), suited to homes, shops and small offices.

What is the largest solar panel I can use?

With 20 A maximum PV input current, the inverter supports high-power modules up to 800 Wp.

Will it work if my grid voltage is low or unstable?

Yes. The AC operating range is 90–290 V, so the inverter keeps exporting through low and high voltage. A 50 V start-up voltage also lets it begin generating earlier in the day.

Can I monitor generation on my phone?

Yes. Use the XMonitor app to see daily generation and fault alerts. Monitoring works over Wi-Fi, GPRS or local mode, with USB / RS485 communication interfaces.

Is it suitable for outdoor installation?

The inverter is IP66 rated, uses fanless natural cooling and operates from −20 °C to 65 °C, so it can be installed outdoors in Indian conditions.

What warranty and certifications does it carry?

It comes with a 10-year warranty and is certified to BIS IS 16221, IS 16169 and IS 17980.
