Q.What is the difference between an inverter and an online UPS?
A home inverter switches from grid to battery within 10–20 milliseconds — perfect for lights, fans and TVs. An online double-conversion UPS delivers zero-transfer-time, filtered pure sine-wave power and is required for servers, medical equipment, CNC machines and sensitive electronics.
Q.Which is the best pure sine-wave inverter for home in India?
For most homes, a 900VA–1500VA pure sine-wave inverter from Su-vastika, Luminous, Microtek, Su-Kam or Durasol is ideal. Pure sine-wave output protects sensitive appliances like refrigerators, LED TVs, laptops and mixer grinders.
Q.What VA rating do I need?
Add up the wattage of all appliances you want to run, then divide by 0.8 to get VA. For example, 700W of load ÷ 0.8 = 875VA, so a 900VA inverter fits. For growing loads, size 30% higher.
Q.Do you sell online UPS for offices and data centres?
Yes — we stock 1kVA, 2kVA, 3kVA, 5kVA and 10kVA online double-conversion UPS systems from Su-vastika and Microtek, with internal or external lithium/SMF battery banks and remote-monitoring options.
Q.Do you offer installation and AMC?
Yes — free installation for home inverters, and paid site-survey plus annual maintenance contracts (AMC) for commercial online UPS deployments.
