SOLAR300 - SOLAR300N 5.1.7. Memory type setting The meter permits saving of recordings both in its internal memory (about 15Mbytes) and by using an external compact flash (see § 5.7.5 for details) fitted (see Fig. 3). Regardless of the capacity of the memory inserted, the maximum size of a recording is set to 32Mbytes. A Compact Flash memory of higher capacity will therefore be able to contain a high number of recordings, each one of which will have a maximum size of 32Mbytes.

PAGE 188
SOLAR300 - SOLAR300N 10.3. NOTES ON MPPT (MAXIMUM POWER POINT TRACKER) Solar irradiation on a surface such as the surface of a photovoltaic system has extremely variable characteristics, since it depends on the position of the sun with respect to the surface and on atmospheric conditions (typically, on the presence of clouds).
PAGE 189
SOLAR300 - SOLAR300N The reason why MPPTs are used is simple: a photovoltaic system without MPPTs may operate anyway; however, with the same solar irradiation, it provides less energy. There are inverters with 1, 2 or also 3 inbuilt MPPTs available on the market. Typically, the inverters with more than one MPPT are used in systems where: - The different photovoltaic systems it consists of “forcibly” have different inclinations or directions.

SOLAR300 - SOLAR300N 10.5.2. Limit values for harmonic voltage EN50160 standard fixes the limits for the harmonic voltages, which can be introduced into the network by the power supplier. In normal conditions, during any period in a week, 95% of the RMS values of each harmonic voltage, mediated on 10 minutes, shall be lower than or equal to the values stated in the following table.
PAGE 192
SOLAR300 - SOLAR300N 10.5.4. Presence of harmonics: consequences In general, even harmonics, i.e. the 2nd, 4th etc., do not cause problems. Triple harmonics, odd multiples of three, are added on the neutral (instead of deleting each other) thus creating a condition of overheating of the wire which is extremely dangerous.

INRUSH CURRENTS The SOLAR300N meter permits the real time detection of inrush current events, typical of start-up of electrical machines and also for other industrial applications (e.g. troubleshooting problem regarding loads switching, correct calculation of protection devices, oscillating currents, etc…) as shown in the following pictures: Fig. 258: Parameters of standard inrush current event Fig.

SOLAR300 - SOLAR300N FIX: The meter detect and recording a event each time the TRMS value of current, calculated on each half period (10ms @ 50Hz, 8.3ms @ 60Hz), it’s over the limit threshold defined by user. A new event is detected by meter always if the current value decrease under the set limit threshold.

SOLAR300 - SOLAR300N 10.8. SUPPLY VOLTAGE UNBALANCE In normal conditions the supply voltage and the final loads are perfectly balanced. Unbalances are possible in trouble situations (low insulation) and/or phase circuits interruptions. Moreover, in single phase systems, the balance can be only statistic. In order to design a correct protection installation a thorough study of anomalous conditions on three phase systems was performed.

VOLTAGE FAST TRANSIENTS (SPIKES) The meter considers all the phenomena associated to the phase voltage as voltage spikes which have the following properties:  Fast slope variations of voltage waveforms.  Exceeding a limit threshold fixed by user before starting a recording. The maximum number of recorded events in a half period (10ms @ 50Hz, 8.3ms @ 60Hz) is 4. The maximum number of recorded events by meter during a recording is 20000.

SOLAR300 - SOLAR300N Note: It shall be noted that the expression of the phase Reactive Power with no sine waveforms, would be wrong. To understand this, it may be useful to consider that both the presence of harmonics and the presence of reactive power produce, among other effects, an increase of line power losses due to the increased current RMS value. With the above given relation the increasing of power losses due to harmonics is added to that introduced by the presence of reactive power.
