Many thanks Tesla,
In this North America job I'm just responsible for compliance with our general design guidelines. The limitations on site are an existing 1 phase 37,5 kVA tranny and some equipment of a third party. So our power supply has been limited to 70A @ 240V. I just wanted to make some proposals how to use these 70A in the most effective way. With regard to 2 VSDs I would have head pain because of extra cooling requirements as the whole installation is exposed to sun and all other weather influences.
I will ask my colleague to check that way.
Btw. this is my first single phase installation after 20 years in that business. And the client is a PoCo.
