8 kVA Home Voltage Stabilizer, Single Phase, 110V~240V

Note: The provided 8 kVA voltage stabilizer is 1-phase (L, N, G) by European standards. We can customize the split phase (L1, L2 + G) like the USA standard, just confirm with us by email after ordering.

Q1: Is an 8 kVA stabilizer sufficient for my home?

An 8 kVA (8000 VA) stabilizer is suitable for protecting the essential circuits or the entire electrical load of a typical medium to large home. As a general rule, the stabilizer's capacity should be 1.5 to 2 times the total power (in kVA or kW) of the appliances you intend to connect and run simultaneously. For example, if your combined simultaneous load is around 4-5 kVA, this unit would be an excellent fit. For inductive loads like motors (in air conditioners, pumps), it's recommended to choose a capacity 3 to 5 times the motor's rating to handle the high starting current.

Q2: What happens when the input voltage is too high or too low?

The stabilizer has built-in protection thresholds. When the input voltage exceeds approximately 250V±2V (over-voltage) or drops below approximately 185V±2V (under-voltage), the unit will automatically cut off the output to protect your connected appliances. Power will be restored automatically once the mains voltage returns to within the stabilizer's operable input range (95-125V or 190-250V).

Q3: Can this stabilizer be installed in a confined space, like a ceiling?

It is not recommended to install this stabilizer in a confined or enclosed space, such as a ceiling. The unit weighs 15 kg and requires adequate ventilation for heat dissipation. It should be installed in a well-ventilated area with clearance from walls, following standard electrical safety practices, and within its specified operating temperature range of -10°C to +40°C.
