Page 30: Reverse Current
Electrical Connection 6.3.3 Reverse Current Advice on Generator Configuration for PV Systems Using the Sunny Mini Central In contrast to the Sunny Boy string inverters, three and more strings are usually connected in parallel in the PV generator of a system using the Sunny Mini Central. 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 31 Technologie AG Electrical Connection Despite the fact that these faults are very unlikely, and extremely rare in practice, preventative measures must still be taken. After all, these types of faults carry a high potential for damage and danger, since all modules in the affected string may be damaged and the local heating may also cause secondary damage.
- Page 32 Electrical Connection Technologie AG 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 effect of any shadowing which may occur.
-
Page 33: Design Notes
Technologie AG Design Notes Check the following points below: Step Test 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 at 5 A short-circuit current The maximum reverse current is 3 x 5 A = 15 A. -
Page 34: Connecting The Ac Output
Electrical Connection 6.4 Connecting the AC Output 6.4.1 Requirements For connecting the AC output, the following requirements must be satisfied: Connection Requirements When connecting an inverter to the public grid, follow the connection requirements of the local grid operator! The Sunny Mini Central is designed for operation on 220 V - 240 V grids. Additionally, it is equipped with an automatic grid frequency identifier and can thus be connected to a 50 or 60 Hz system without further parameterization. - Page 35 Technologie AG Grid Impedance Due to a high grid impedance, a high line resistance or a high voltage at the feed- in point, a high AC voltage may result at the connection point of the Sunny Mini Central. In Germany, the 10-minute average of the output voltage (Uac) of the Sunny Mini Central is limited to 253 V according to DIN VDE 0126-1-1.
- Page 36 Electrical Connection The diagram shows the respective curves for a grid voltage without mains supply. A maximum possible feed-in power per phase (X axis) is obtained for the respective curves depending on the grid impedance (Y axis). With three-phase connection and symmetrical feeding, the maximum possible feed-in power per phase is approximately doubled.
- Page 37 Technologie AG Cable Connection The connection terminals in the Sunny Mini Central are suitable for wire cross-sections of up to 25 mm². The external diameter of the cable must therefore be between 11 mm and 25 mm. If you use a cable with a cross-section smaller than 14 mm (11 mm minimum), the rubber bushing in the screw fitting must be replaced by the one included with the inverter at delivery.

Page 41: Connecting The Ac Output
Technologie AG 6.4.2 Connecting the AC Output To connect up the AC output, follow these steps: Step Instruction Check the grid voltage! For Germany, the following applies: If the grid voltage is constantly higher than 253 V, the Sunny Mini Central will not be fully operational. In this case, contact the local grid operator for assistance. - Page 42 Electrical Connection Step Instruction Connect the protective earth (PE) of the mains cable to the right terminal of the terminal block (see figure to the right). To do this, the PE wire must be 5 mm longer than the L and N wires! If a second protective earth connection is required, you can use the additional connection terminal directly on the Sunny Mini Central's housing for this purpose.
