The bidirectional electronic stabilizers SE Solar prevent the interface protection units from detaching, stabilizing the grid voltage. They can be installed in the following positions:
a) Downstream of the exchange / sale energy meter (recommended) to stabilize both the user and the PV system;
b) Inverter energy meter’s output to stabilize the PV system only;
c) On the section that supplies the user to stabilize the user only.

For sizing, first of all we must consider that the power in kVA of our bidirectional electronic stabilizers SE Solar is at cosphi 0.8. Given this, for the above configurations we will have:
a) The stabilizer will be sized for the greater power between the nominal power of the PV system and the peak power of the user;
b) The stabilizer will be sized for the nominal power of the PV system;
c) The stabilizer will be sized for the peak power of the user.

While there is no problem for the PV system, for the user it is necessary to pay particular attention to the peak currents of particular loads, such as motors (= 3 In) and compressors (= 10 In). In light of all this, for example, for a PV system up to 6 kW, it is necessary a bidirectional electronic stabilizer SE Solar of at least 7.5 kVA, mod. SE-15, always after checking the absorption of the customer’s loads (in few words it is fine if the customer has max 2 air conditioners and a small water pump).

The SE electronic stabilizers are designed for continuous operation and guarantee maximum reliability and minimum maintenance, and have been offered in our production range for more than 50 years.

The SE stabilizers are products called ”electronic”, because both the control and the regulation system are purely electronic.

Our stabilizers take advantage of the principle of the series transformer to increase or to decrease the value of the input voltage in a gradual and rapid way through the secondary winding in series of a transformer supplied by power triacs and controlled by an electronic board with microprocessor at high speed.

The principle of the stabilization in alternating current is to add or to subtract to mains voltage a voltage with the same frequency and in-phase or out-of-phase (180°), always taken by the mains, in order to turn back the output voltage within the planned range. The supplying voltage of the series transformer is given by power triacs, driven by an electronic board that, constantly verifying the value of the output voltage, provides to supply the series transformer up to the attainment of the nominal voltage.

So far SE stabilizers have been installed in several African Countries, like Nigeria and Angola, to stabilize voltage coming from power stations very far from towns or villages, which use that energy.
