Low voltage? AC keeps tripping?

In this heat wave your solar runs the AC all day. But at night there's no solar β€” the AC runs on the grid, and the voltage drops low. On low voltage your AC won't start, and the compressor can burn out. A Voltec AC stabilizer boosts that weak voltage back to a steady 220V β€” so your AC runs cool all night, and the compressor stays safe.

Pick by how low your voltage drops

All three are 10,000W, specially designed for 1 and 1.5 ton ACs. The difference is how low a voltage they keep working at. Not sure how far your voltage drops? Message us β€” we'll tell you the right one, free.

Why a Voltec AC stabilizer

Not a generic stabilizer β€” specially built for air conditioners, so your AC starts on a weak night grid and runs without straining the compressor.

Built for ACs β€” 10,000W
Sized and tuned for 1 and 1.5 ton air conditioners, inverter or normal.
99% pure copper transformer
Real copper, not aluminium β€” runs cooler and lasts for years.
Energy saver β€” 10% less current
Draws about 10% less current, so your AC runs on a lower electricity bill.
Starts your AC on low voltage
Boosts a weak night-time grid back to a steady 220V, so the AC starts and runs.
Protects the compressor
Low voltage burns AC compressors. Steady output keeps yours safe.
1 year warranty
Every unit is backed for a full year. We service what we sell.

FAQ

Common questions.

Why does my AC work in the day but not at night?
In the day your solar runs the AC on steady power. At night there is no solar, so the AC runs on the grid β€” and during the heat wave the grid voltage drops low. On low voltage an AC either will not start, or the compressor strains and can burn out. An AC stabilizer boosts that low voltage back to a steady 220V, so your AC starts and runs safely all night.
Which model do I need β€” R2, R3 or R4?
Pick by how low your voltage drops at night. R2 works from 150V (lighter sag, inverter AC). R3 works from 120V β€” the most popular, for inverter and normal ACs. R4 works from 100V, for severe low-voltage areas. Not sure how low your voltage gets? Message us on WhatsApp and we'll tell you the right one.
Will one stabilizer run a 1.5 ton AC?
Yes. All three models are 10,000W, specially designed for 1 and 1.5 ton ACs β€” inverter or normal. R3 and R4 handle both inverter and normal ACs.
Does it really lower my electricity bill?
It draws about 10% less current thanks to the pure-copper, energy-saver design. Over a hot summer of nightly AC use, that adds up on your bill.
Do you supply dealers / bulk orders?
Yes. We supply dealers and bulk buyers across Pakistan. Message us on WhatsApp with your quantity and city and we'll share a quote.
