28、ation 4.1 General Technical products are usually brought into the market with a documentation providing information to the user regarding the operating conditions and its intended purpose. A data sheet specifies a product to the extent that the contained data could be consulted for planning or dimen
29、sioning. The size and organization of the data sheet are left to the manufacturer. It is however recommendable to be limited to a double-side printed on DIN-A4 sheet whereby a topic-specific separation is favourable. 4.2 Short description In short the characteristics of the inverter are to be descri
30、bed. Special characteristics of the inverters can be mentioned. For better identification of the equipment, its photo or its true design drawing should be included on the data sheet. The internal design of the inverter should be represented in clear way (e.g. by means of a block diagram). 4.3 Confor
31、mity The conformity to relevant norms and standards must be shown in the data sheet. 4.4 Electrical parameters The electrical parameters from 4.4.1 to 4.4.2 are to be regarded as minimum requirement for a professional system integration of an inverter. 4.4.1 The following parameters of the input sid
32、e must be indicated: Vdcmax, Vdcmin, Vdcstart 2), Vdc,r, Vmppmax, Vmppmin, Idcmax, number of independent MPP inputs (if applicable). NOTE 1 The maximum voltage of the connected solar generator is to be determined in individual cases from the planner. The maximum input voltage of the inverter may not
33、 be exceeded at any time. NOTE 2 The specification of maximum and minimum MPP voltage can also be indicated as ranges. 4.4.2 The following parameters of the output side must be indicated: Vacmax, Vacmin, Vac,r, Iacmax, Pac,r, fr, fmin, fmax, cosphiac,r. Additionally the number of phases to be connec
34、ted at the output and the number of phases fed in have to be noted. NOTE The specification of the maximum and minimum output voltages and frequencies can also always be specified in each case as ranges If only one value is given, the default status at delivery has to be used. 4.5 Characterisation of
35、 the operating performance 4.5.1 The indication of the rated power (Pac,r) refers to the respective rated values of the connected grid (e.g. 230 V/50 Hz). The rated power is given at the rated input voltage and the ambient temperature of (25 3) C. NOTE In addition of this, the ability of the inverte
36、r, to supply the rated power even at higher ambient temperatures can be started together with the time the inverter can supply this power (e.g. 2 h or unlimited). 2)The indication of the start-up input voltage is necessary only if the input voltage is used as switching on criterion for the inverter.

38、 in tabular form. A graphical representation is optional (example: Figure 1). In all cases the efficiency is referred to the standardized power output (Pac/Pac,r). Figure 1 Representation of the inverter efficiency Pacis output power at percentaged rated power (5 %, 10 %, 20 %, 25 %, 30 %, 50 %, 75
39、%, 100 %). As supplement to the EN 61683 additionally the value must be given at 20 % and 30 % of the rated power. 4.5.4 The computation of the European efficiency (weighted efficiency)EU is taken as the partial load efficiencies as indicated by (1) and the full load efficiency are weighted after th
40、e frequency of their occurrence. ()( )( )()( )()%100%50%30%20%10%52,048,01,013,006,003,0 +=EU(1) The partial efficiencies are to be determined at the rated input voltage of the inverter. NOTE A standard on the efficiency is in consultation and will replace the definition of the EU given in this Euro
41、pean Standard. 4.5.5 For the purpose of self-protection routines can be implemented into the inverter, which prevent a damage (current power temperature derating). Any self protection routine that causes derating must be described in tabular or graphical form over the entire permitted operation rang

43、ntained in the data sheet: - safety class system according to IEC 62103; - data for galvanic separation (with or without transformer); - kind of integrated utility interface (indication of the sets of rules, regulations or laws: e.g. VDE V 0126-1-1) 4.7 Operating conditions The operating conditions
44、for the inverters are differentiated as (unprotected in the open, protected in the open, air-conditioned in interiors, without air-condition in interiors). The degree of severity depends on the use of the inverter and is to be specified by the manufacturer. For inverters to be used in the outdoor th
45、e indication of the appropriate climatic class must be specified according to IEC 60721-2-1 by the manufacturer. Further data concerning the operating conditions of inverters should be contained in the data sheet: - rated range of the ambient temperature in which the inverter is to be operated may b
