How do I use the Sunny Tripower inverters by SMA in PV*SOL?
The Sunny Tripower inverters have 2 asymmetrical MPP trackers and there are thus a few things that need to be taken into consideration with the design.
In the 2D-planning you have to design to sub arrays. One for the modules that you want to connect to the input A of the inverter and one for the rest of the modules which you want to connect with input B.
The main inverter (input A) is saved in PV*SOL’s inverter database with a reference for the inverter type. In addition, for the second array, the Tripower Extraeingang inverter (input B) must be selected (for all models the same).
Input B can bear up to 8.8 kW in a maximum of one string. This actual installed power must then be withdrawn from input A. If you want to configure input B with more than 2 kW, you will need to go to "Databases" - "Inverter" - "Grid Connected" and select the inverters that match the power values correspondingly (input A low, input B high) and save in the database as a user-created data record using "Save As".
As a rule, the majority of modules should be connected to input A and the rest of the modules to input B (ewith g, 60 modules - 2 strings with 24 modules to input A and 1 string with 12 modules to input B).
In 3D planning you have to select the self-created Tripower records as appropriate inverter combination.
It is recommended that a test using the manufacturer’s design tool is carried out!
