PVI 36TL Installation and Operation Manual PVI Series Inverters 2.3.1 DC Connection 1) Working Mode PVI 36TL inverter has two PV input sections: DC Input-1 and DC Input-2. These two sections can work in “Parallel mode” or “Independent mode” (see Figure 2.20). The default setting from the factory is “Independent mode”. In Parallel mode, the two PV input sections share one MPP Tracker; In Independent mode, each PV input section works with independent MPP Tracker.

DC input power Rated DC input power of (Parallel mode) each input section (Independent modeDefault from factory) 37kW (70A) 18.5kW (35A) Note: The standard configuration is “Independent mode”. If it needs to switch to the “Parallel mode”, please take the following steps to change the internal configuration: 1. Remove the cover of the wiring box. (see Figure 2-15) 2.

Customers must verify that the appropriate fuses are installed depending on the actual configuration of PV strings. (a) Each independent string of DC input from the PV strings needs fuse protection.
PVI 36TL Installation and Operation Manual PVI Series Inverters 3) DC Cable Connection To ensure the optimum performance of the inverter, please read the following guidelines before DC connection: (a) Confirm the DC configuration referring to Table 2.5 and ensure that the maximum open circuit voltage of the PV modules is lower than 1000 VDC under any conditions. (b) Confirm that the PV strings for each MPPT of the inverter are of the same type and specification before connection.
PVI 36TL Installation and Operation Manual PVI Series Inverters *Consider combining MPPT zones for such configurations **Use Inline fuses to adhere to module series fuse rating if necessary Note: When using Y connectors to combine two strings you have to use a UL listed parts such as: Amphenol Overmolded Solar Junction. When combining 2 strings you should use a Y connector that has a fuse in each branch equal to the module series fuse rating. For 9 inputs you can place the 30A fuse in any fuse holder.

However, this also means that one must consider these two zones as two separate inverters and power must be balanced as much as possible between the two MPPT zones.
PVI 36TL Installation and Operation Manual PVI Series Inverters Figure 2.27 - Two MPPTs Combined to Operate as One When the copper jumpers are installed across DC+ and DC- this allows the power to be evenly distributed between the two trackers such as applications of odd number of strings. Note 1: The temperature rating of the input wirings should be no less than 90°C (194°F). Note 2: The recommended fuse types are configured according to the condition that the input strings are the same. 2.3.
