V-Guard VG 400 for 1.5 Ton A.C (170V to 270V) Original 3 Year onsite wrranty GREY

This doesn't take load of split AC. Light gets on but AC is not on. This model was suggested by Amazon while purchasing. Pl repace with higher model

I purchased it second time as i am satisfied with the performance of the first one.

Very nice product from the trusted brand so no issues so far.

The company claims an operating range of 170V to 270V on paper, but the reality is entirely different. This stabilizer consistently trips at 262V, falling well short of its advertised upper limit. This is a massive red flag, especially if you live in a locality with grid-tied rooftop solar setups. In my area, daytime grid voltage naturally idles around 250V and easily spikes to 285V when the neighborhood load is low. Even during peak afternoon hours with multiple ACs running in the area, the voltage hovers around 260V to 263V. Because this stabilizer cannot handle anything past 262V, it constantly cuts power, leaving the AC useless exactly when you need it most. Attempting to get this resolved or calibrated via customer care was a frustrating loop. The frontline support couldn't grasp the technical issue. When a service engineer finally visited, he tried to justify the premature tripping by claiming a "2.5% accuracy margin" on the 270V limit (which would technically mean a trip range of 263.25V to 276.75V). Even by his own flawed math, my unit tripping at 262V proves the product is simply underperforming and defective by design. The Bottom Line: If your house's baseline voltage is around 250V, this model only gives you a useless 10V regulation window before shutting down. Constant tripping doesn't protect your AC; it actively damages the compressor through short cycling. If you have a solar PV system at home or in your neighborhood, absolutely skip this and buy a stabilizer with a much higher upper-voltage tolerance.

Nice product, once purchased works for minimum of 5 years . My second purchase
