India's Most Trusted Inverter & Sine Wave Inverter Suppliers — Home to Industrial Grade

What size inverter do I need for a 2BHK home in India?

A: Standard 2BHK load for backup: 4 fans (300W) + 4 LED lights (36W) + 1 TV (100W) + 1 fridge (150W) = 586W + 25% margin = 733W ÷ 0.8 PF = 916 VA minimum. Specify 1,100VA (1.1kVA) inverter for comfortable headroom. If you want to run a 1.5-tonne split AC on backup, upgrade to 3.5kVA pure sine wave inverter. Always consult your dealer with a complete appliance list for accurate sizing.

What is the difference between tubular and SMF (sealed) batteries for inverters?

A: Tubular (flooded lead-acid) batteries: 4–6 year life, require distilled water top-up every 2–3 months, produce hydrogen gas (need ventilation), best for areas with long daily outages (2+ hours). SMF (Sealed Maintenance Free/VRLA): 2–4 year life, zero maintenance, can be installed indoors, ideal for areas with short (<2 hour) daily outages. Tubular offers better lifecycle value for high-usage households; SMF suits urban apartment use with limited outages.

Can I use a home inverter to power a 1.5-tonne split AC?

A: Yes, but you need: (1) minimum 3.5kVA pure sine wave inverter (AC starting surge is 3× running wattage — a 1.5T AC needs ~2kW running and ~6kW starting surge), (2) minimum 150Ah tubular battery for even 30 minutes of AC backup. Modified/square wave inverters cannot power modern inverter-type ACs. Running an AC on battery backup is expensive (150Ah battery gives approximately 30–45 min of AC use) — most people use inverters only for essential non-AC loads.

What is a solar-hybrid inverter and how does it differ from a regular inverter?

A: A solar-hybrid inverter combines an MPPT solar charge controller, battery charger, and inverter in one unit. It prioritises charging batteries from solar panels, then grid, and switches to battery during outages — all automatically. A regular inverter charges batteries only from the grid. Solar-hybrid inverters are eligible for PM Surya Ghar government subsidy (₹30,000–₹78,000) when installed with panels. MNRE approval is mandatory for subsidy eligibility.

What is Automatic Generator Start (AGS) in inverters?

A: AGS (Automatic Generator Start) is a feature in high-capacity inverters that automatically starts a diesel/petrol generator when battery charge drops to a set level (typically 20–30%), charges the battery from the generator, and shuts off the generator when batteries reach full charge. This eliminates manual generator management during extended grid outages — critical for large homes, commercial establishments, and rural properties where outages can last 4–8 hours.
