Line voltage drop should be less than 2% from junction box to inverter.Inverter is recommended to be installed on or near PV panel bracket , which can save cable and reduce DC loss. 4.5 Connecting DC Input Power Cables Connect the DASS TECH inverter to PV arrays over DC input power cables. Check polarity of PV array, to ensure the correct wiring of PV array; Please don't put the positive or negative of the PV array connect to earth. Input mode selection: DASS TECH inverter has 2 MPPT, The two MPPT can run independently, but also can be operated in parallel, According to the system design, the user can choose the mode of MPPT operation. Note Independent mode (default): PV modules generate electric energy when exposed to sunlight and can create an electrical shock hazard. Therefore, when connecting DC input power cable, cover PV modules by using opaque cloth. Before performing electrical connections, ensure that voltages of the DC cables should be within the safe voltage range, that is, lower than 60 V DC, and the DC SWITCH is OFF. Otherwise, the high voltage may result in fatal danger. If the two MPPT panels is independent, the input mode should be set as "independent mode". The setting method is introduced at chapter 6.3. Danger Ensure that the following conditions are met. Otherwise, fire accident may occur. Parallel mode : PV modules connected in series in each PV array are of the same specifications. The open-circuit voltage of each PV array is always lower than or equal to 1100 V DC. The open-circuit voltage of each PV array is always lower than or equal to 15 A DC. The output power of each PV array is always less than or equal to the maximum input power of the DASS TECH inverter. The positive and negative terminals of PV arrays connect to the positive and negative DC input terminals respectively. If the two MPPT panels is paralleled together by combiner, the input mode should be set as "parallel mode". The setting method is introduced at chapter 6.3. Caution If the DASS TECH inverter connects to the power grid directly, ensure that the PV arrays are not grounded. If the DC voltage is a non-zero value between the positive terminal of PV arrays and the ground, the PV arrays are subject to insulation faults. Rectify the fault before connecting cables. During PV array and DASS TECH inverter installation, the positive or negative terminals of PV arrays may be grounded if power cables are not properly installed or routed. In this case, an DC short circuit may occur and damage the DASS TECH inverter. If the PV arrays need to be grounded, install a three-phase four-wire isolation transformer on the output side and disable the ISO detection function by referring to 6.2.10 Setting Isolation Parameters. If an isolation transformer is not installed, the DASS TECH inverter may be damaged. Note According to the inverter type, choose the inverter accessories (cables, fuse holder, fuse, breaker etc.), DASS TECH inverter with PV array should be excellent performance, reliable quality. The open circuit voltage of PV must be less than Maximum DC input voltage of DASS TECH inverter, The output voltage of the solar array must be consistent with the MPPT voltage range.

Before removing the positive and negative connectors, ensure that the DC SWITCH is OFF. 5 Commissioning of inverter 5.1 Safety inspection before commissioning Caution Figure 4-28 Removing a DC input connector Ensure that DC and AC voltages are within the range permitted by the inverter. Attention 5.2 Start inverter Step 1 Turn on DC switch. Step 2 Turn on AC switch. 4.6 Safety check Photovoltaic array When the solar arrays generate adequate power, the inverter will startup automatically. Display showing “normal” indicates correct operation. Before the inverter operation, need to be examined for the photovoltaic array, Check Open circuit voltage of the each PV array whether accord with the requirements. − Ensure Open circuit voltage of the each PV array accord with the requirements; Step 3: Choose the correct country code. (refer to section 6.3 of this manual) Notice: Different distribution network operators in different countries have different requirements regarding grid connections of PV grid connected inverters. Therefore, it's very important to make sure that you have selected the correct country code according to requirements of local authority. Please consult qualified electrical engineer or personnel from electrical safety authorities about this. − Ensure that the positive and negative polarity is correct. DASS TECH inverter DC connect Use the multimeter to check the DC side voltage and current; Check the DC cable, Note the positive and negative poles cannot be reversed, Consistent with the positive and negative pole of photovoltaic array, measured each input Open circuit voltage Compare the voltage, if the difference is greater than 3%, PV array line may be a fault DASS TECH inverter AC connect Ensure the AC breaker of the inverter is off Check the inverter phase with grid is connected properly, Check the voltage of each phase is within a predetermined range, if possible, Measure the THD, If the distortion is serious, the inverter may not work.
