Single-phase inverter voltage stabilizer Volter Smart-18 (18.0 kW) is a high-tech inverter device Smart-18, developed for comprehensive protection of sensitive electronic electrical equipment from any emergency situations in the grid. It reliably protects against dangerous impulse surges, long voltage sags, high-frequency noise, and current frequency fluctuations. Thanks to appropriate power capacity, this stabilizer is the optimal choice for facilities with a corresponding number of loads where it is necessary to ensure stable operation of demanding equipment.
The operation of this model is based on advanced double conversion inverter technology. The device continuously converts incoming AC power into DC and then shapes output AC power with a pure sine wave and a fixed value of 220 V. Thanks to the stepless regulation principle, the voltage is corrected absolutely smoothly, without any fluctuations or delays typical of outdated relay or step-type devices.

Key Benefits of the Model
- Ultra-high accuracy (±0.50%): the stabilizer preserves output voltage within strict limits of 217.8 V to 222.2 V, providing ideal conditions even for high-precision medical or laboratory equipment.
- Climatic design: operating temperature range (from +5°C to +40°C) guarantees reliability of the device in residential, office, and any heated rooms.
- Compatibility with solar and generators: the unit is adapted for operation with solar station inverters (handles reverse current) and autonomous fuel generators.
- Silent operation: due to the absence of moving mechanical parts, the device runs almost silently and does not create acoustic discomfort.
- Lifetime warranty: unprecedented warranty conditions from the manufacturer confirm exceptional reliability of the device and durability of all components.
Safety and Protective Functions
- Emergency overload shutdown: protective power cut-off upon long-term exceedance of the allowable load power.
- Temperature control: constant overheat protection of power switches and autotransformer with activation of forced cooling ventilation.
- Emergency short circuit trip: ultra-fast output de-energization to a short circuit in the connected load to prevent damage to power modules.
- Impulse spike protection: effective absorption of high-voltage noise in the mains grid caused by external factors.
Installation and Connection Recommendations
- Wall-mounted installation: the stabilizer body is securely fixed on a vertical surface using included mounting elements.
- Clearance for ventilation: leave free space around ventilation openings (at least 10–15 cm) for unobstructed forced cooling.
- Power cables connection: connection to power supply lines is carried out via terminal strip. The copper feeder cable cross-section must correspond to maximum device current.
- Environmental conditions: the device has IP20 standard protection class, which implies installation in rooms with moderate humidity and dust levels.
Application Area: Where the Device is Used
- Cottages and private houses: the stabilizer nominal power are designed for safe operation of all appliances in a large cottage, office, or commercial site.
- Heating equipment: provides a pure sine wave, which is critically important for gas and solid-fuel boiler automation.
- Computers and office equipment: protects network equipment office appliances from sudden impulse noise.
- Medical offices: maintains stable power for sensitive electronic equipment in clinics.
