SE Solar bidirectional voltage stabilizer for solar plants
Country: Italy · Model: SE Solar
SE Solar stabilizes the voltage at the connection point of a solar power plant for both directions of energy flow. The unit removes a typical problem of a plant on a weak line, where the inverter raises the voltage at peak generation hours and the interface protection disconnects the plant.
- Purpose
- stabilizing the mains voltage at the solar plant connection point to prevent tripping of the interface protection
- Type
- electronic bidirectional stabilizer
- Power calculation
- the kVA rating is given at cos φ 0.8
- Installation options
- after the exchange meter, at the output of the solar plant meter, or on the consumer line

Description
The basis is an electronic stabilizer of the SE series, modified for bidirectional operation, so it correctly regulates both consumption from the grid and export into it. The voltage at the inverter terminals stays within permitted limits, the interface protection does not trip, and the plant does not lose the energy it has generated. The connection scheme is chosen according to the site configuration: the unit is installed after the exchange meter, at the output of the solar plant meter, or on the consumer line. The kVA rating is given at cos φ 0.8, so when sizing for an inverter rated in kW the power is converted using this factor. The regulation principle is the same as in the base series: a buck-boost transformer with triacs and microprocessor control.
How to choose
The stabilizer power is selected from the inverter rating converted to kVA at cos φ 0.8, with a margin for generation peaks. The installation point depends on the task: on the consumer line the unit also protects the load, while after the exchange meter it stabilizes the whole connection point. If there is no solar plant and only consumption needs stabilizing, the standard SE offers 1–75 kVA single-phase and 3–2000 kVA three-phase at 98% efficiency.

FAQ
Why does a solar power plant disconnect because of high voltage?
On a weak line the inverter export raises the voltage at the connection point, and the interface protection switches the plant off. SE Solar keeps the voltage within permitted limits and prevents such disconnections.
Where is the SE Solar stabilizer installed?
After the exchange meter, at the output of the solar plant meter, or on the consumer line, depending on the site scheme.
How to convert the SE Solar power from kVA to kW?
The kVA rating is given at cos φ 0.8, so the active power equals the rating multiplied by 0.8.
How does SE Solar differ from the standard SE stabilizer?
The standard SE is designed for energy flowing from the grid to the load. SE Solar is bidirectional and works correctly when the plant exports energy into the grid.
