Here are the most common questions asked to V Guard support regarding the DU 1000 Smart.
Q: Can I run a 1.5 Ton AC on the V Guard DU 1000 Smart? A: No. The manual clearly specifies a maximum load of 800W continuous. A 1.5 Ton AC requires 1500W+ starting power. Attempting this will instantly cause an overload trip or damage the inverter.
Q: Why does my inverter switch to battery mode even when there is electricity? A: This is likely the "AVR Boost" mode. If your voltage drops below 180V, the inverter switches to battery to protect your appliances. Check the display; if input voltage is low (e.g., 140V), the unit is working correctly.
Q: The display shows "Fault" or "Err." What do I do? A:
Q: How long will the backup last? A: This depends entirely on your battery (Ah rating) and load (Watts). For a 150Ah battery with 300W load, approximately 4 hours. With 600W load, approximately 2 hours. This is a math calculation, not a warranty claim.
Q: Is this a Pure Sine Wave or Square Wave inverter? A: The "DU 1000 Smart" is a Pure Sine Wave inverter. It is safe for electronic devices like medical equipment, laptops, and digital clocks.
The manual instructs you to use the metal keyhole slots on the back of the unit.
V-Guard typically offers 2-year warranty on the inverter (excluding battery). Register product online or via warranty card. For service, contact V-Guard authorized service center – do not open the unit yourself.
