General product information:

1. The inverter is non-isolated PV inverter for connection with public medium or high voltage grid, for outdoor or indoor use.

2. The adjustable power factor range of SUN2000-330KTL-H1 and SUN2000-330KTL-H2 is 0.8 inductive(under-excited) to 0.8 capacitive(over-excited).

3. LVRT logic is as follow: Determination of entering LVRT mode: Any phase voltage is lower than 0.9Un, the inverter will enter LVRT mode.

LVRT mode behavior: During LVRT fault, positive and negative sequence of reactive current is determined by k-factor. K-factor of positive sequence is 2 and K-factor of negative sequence is 0. The injection of reactive current is first priority. The supply of active has the second priority and the active power preferably be maintained during voltage drop, unless the rated apparent current is reached. Under unbalance voltage

by k-factor. K-factor of positive sequence is 2 and K-factor of negative sequence is 0. The injection of reactive current is first priority. The supply of active has the second priority and the active power preferably be maintained during voltage drop, unless the rated apparent current is reached. Under unbalance voltage fault, the maximum injection of reactive current is limited to 0.4In.

Guangzhou Branch, TÜV SÜD Group 5F, Communication Building, 163 Pingyun Rd, Huangpu Ave. West,Guangzhou, 510656, P.R.China Prior to the fault simulation tests, the EUT should run in normal operating mode. The selected UVRT curve should be used to identify voltage drop points, including the lowest point and the inflection point, as well as other random points in the curve. Selection of the drop time should follow the requirement of the applicable country or region. P 5.3.2 No-load test P Prior to the load test, adjust the fault emulator to simulate symmetrical and asymmetrical voltage drops without EUT connection, and validate that the measured results are as intended. This step ensures that the amplitude of voltage and drop duration can match the requirements in Figure 5. P 5.3.3 Tolerance P The tolerances for drop depth and duration during the no-load test shall reference the requirement of Figure 6 in IEC 61400that the amplitude of voltage and drop duration can match the requirements in Figure 5. P 5.3.3 Tolerance P The tolerances for drop depth and duration during the no-load test shall reference the requirement of Figure 6 in IEC 6140021:2008, and not exceed the values shown in Figure 5. P The tolerance for voltage magnitude is ± 5 % of rated voltage for the period before and during the voltage drop. The tolerance for voltage magnitude is ± 10 % of rated voltage during the period after voltage is recovered. The tolerances shall be measured between 0 and +5 % of rated voltage for the lowest point and the inflection point under no-load conditions. P The duration of each voltage drop is determined according to the requirements of the applicable UVRT curve. The tolerance range for both drop duration and rise time prefers 40 ms. P 5.3.4 Load test P Tests under load shall be carried out after the no-load test results successfully meet the performance requirements. The parameters of the grid fault simulator should be consistent with the no-load test. P With the EUT connected to the grid fault simulator device and the PV simulator(or PV array), the output power should be set to (0,1~0,3)Pn and above 0,9Pn separately. Additional load tests at other power levels The output power is set to 0.2 Pn and 1.0 Pn PClause Requirement + Test result − Remark Verdict
