Technical FAQs 4

How many inverters are connected to the LV winding?

Accordingly, one, two, or three inverters are connected to the LV winding of step-up transformers designed according to current standards [4, 5, 6, 7].

How do inverters convert direct current to alternating current (AC)?

The direct current generated is then converted to a three-phase alternating current (AC) by inverters and connected to the grid via a step-up transformer [1, 2, 3]. Currently, there are limitations on the power rating and voltage level of the inverter.

Does Tesla Solar inverter have a site controller?

For full compliance to IEEE 1547-2018 and IEEE 1547.1-2020 GW.2.0 or SMC shall be used with Solar Inverter. The following specifications reflect Tesla Solar Inverter with Site Controller (Tesla P/N 1538000-45-y). For specifications on Tesla Solar Inverter without Site Controller, see Tesla Solar Inverter and Solar Shutdown Device datasheet.

What is the withstand voltage test for Basic insulation?

According to International Electrotechnical Commission (IEC) 60950, the withstand voltage test for basic insulation is 2U + 1,000 VRMS, where U is the maximum operating voltage of a system. A manufacturer may need to apply a 4,242-V withstand voltage test when designing an 800-V system based on Equation 1:
