General product information: General product information: A solar inverter converts DC current into AC current. The input and output are protected by Varistors to Earth. The unit is providing EMC filtering at the output toward mains. The unit does not provide galvanic separation from input to output (transformer). The output is switched off redundant by the high power switching bridge and two relays in series. This assures that the opening of the output circuit also operates in case of one error. The PV input is also connected to an EMC filter. Before each start up, the isolation of the unit is checked and in case of an insulation fault, the unit does not feed into the grid. The voltage and frequency measurement is performed with an voltage divider which are connected directly to line and neutral. Both controllers get these signals and analyze the data.

With the sensor TX1_1 measured the differential current between line and neutral. The output signal is linked to both controllers (M.GFCI and R.GFCI). Before the system start up, each time an 15mA pulse is send to the GFCI sensor. The sensor has to be response with answer pulse to the both controller. If the pulse is not send, the system displays “GFCI- sensor defect” and the unit does not start to feed into the grid. The DC-injection is measured with the PCB sensor HCT2. This output signal is connected to both controllers as well. The DSP main controller and redundant controller communicate with each other and compare their measurement values, so that in case of a difference, the unit is disconnected. There are two relays in serial on each path (L1 and N). Each DSP controls one pair of relays (one relay at each path). In addition the inverter bridge can be stopped by both DSP’s. Before start-up, the inverter measures the insulation resistance of the PV arrays to PE. If the value is smaller than the intern configured value, the inverter does not connect to the grid. The measurements had been performed with different units. All the results are applicable to the other units as well since they have the same hardware (only difference is the number of capacitors in the DC link) and they are just firmware derated.

C4.5 Over Current Protection

P

The products have to be installed on a a 15 A (IEC) branch circuit for SolarRiver 1700TL and a 20 A (IEC) branch circuit for SolarRiver 2300TL to provide over-current protection.

Note: See installation manual C4.6 Short circuit Current Contribution

P

As Photovoltaic SSEGs are inverter connected, they are deemed to automatically comply with regulations and no further tests are required.

C4.7 Self Monitoring – Solid state Disconnection

N/A

Units do not provide solid state switching relays. In case the semiconductor bridge is switched off, then the voltage on the output drops to 0. In this case the relays on the output will also open.
