  • Page 35: Reverse Current

    Technologie AG Electrical Connection 5.3.3 Reverse Current Advice on generator configuration for PV systems using the Sunny Mini Central In contrast to the "Sunny Boy" string inverters, in the PV generator of a system using the "Sunny Mini Central", three and more strings are usually connected in parallel. This does not sound particularly spectacular but it has practical consequences because, in such large generators, certain faults which are totally uncritical in string systems must be allowed for.
  • Page 36 Electrical Connection Technologie AG Despite the fact that these faults are very unlikely, and extremely rare in practice, pre- ventative measures must still be taken. After all, these types of faults carry a high poten- tial for damage and danger, since all modules in the affected string may be damaged and the local heating may also cause secondary damage.
  • Page 37 Technologie AG Electrical Connection How can reverse current in the modules be prevented? First we must explain that bypass diodes which are the current state-of-the-art in module construction do not influence the reverse current in the module, but only reduce the ef- fect of any shadowing which may occur.
  • Page 38 Electrical Connection Technologie AG Design notes The following must be checked or ensured above all: Step Verification Do all the strings have the same number of series-connected modules? How high is the maximum reverse current in a defective string at nominal conditions? Example: generator with 4 strings of modules with 5 A short circuit current The maximum reverse current is 3 x 5 A = 15 A.

    Technologie AG Electrical Connection 5.4 Connecting the AC output 5.4.1 Prerequisites: For connecting the AC output, the following conditions must be satisfied: Connection requirements When connecting the inverter to the public grid, follow the connection require- ments of the local grid operator. The Sunny Mini Central is designed for operation on 220 V - 240 V grids.
  • Page 40 Electrical Connection Technologie AG (outside Germany), it is deactivated by means of presetting the LdVtgC parameter (see chapter 13.4 „Sunny Mini Central operating parameters” (Page 87). In this case, only the disconnection parameter Uac-Max applies. The following diagram shows the power output the inverter can feed into the grid per phase without leading to a switch-off because of a too high AC voltage.
  • Page 41 Technologie AG Electrical Connection Example: - The grid voltage without mains supply is 230 V. - The grid impedance at the terminal is 1.0 Ohms. Output [kW] per phase The power read on the X axis is approx. 5.8 kW per phase. Consequently, only one Sunny Mini Central may be installed per phase in this ex- ample.
