Comma after ᴀɴᴅ before "for instance"?

Question

I need help with this sentence:

Thus, heat pumps can(,) for instance(,) run whenever there is a high generation of PV electricity(,) or there is a need to increase the electrical load in the grid.

So basically there are three commas that I am unsure about. I would tend to use them. Should I?

"for instance" is a parenthetical. It's presence is not need for syntactic and semantic validity. Parentheticals are typically set off by commas. — Hot Licks, Apr 20 '20 at 12:14
Thanks Hot Licks for your answer. So you would say that all three commas are okay? — PeterBe, Apr 20 '20 at 12:17
Does this answer your question? Is "in fact" always set off by commas mid-sentence? (There are many other threads dealing with parentheticals also. Brackets with parentheticals may be helpful, mentioning zero punctuation instead of offsetting commas, a possibility here.) — Edwin Ashworth, Apr 20 '20 at 14:57

I wouldn't use the last comma, although it is possible to use it, and I'd either suppress one ellipsis or use one more (rather this latter possibility).

"Thus, heat pumps can, for instance, run whenever there is a high generation of PV electricity or whenever there is a need to increase the electical load in the grid".
