[RE-wrenches] 1000Vdc Combiner Block, Fusing

[Kirk Herander]

Yes there is a definite need for 1000vdc Combiner. it does not exist
without as you say custom work by BOS or others.

This was mentioned in past threads but I ended up building my own for a 1
mwh high voltage LFP system. All ul Components and fusing, but inspection
was not required.

Contact me off list no give you a de facto BOM of Items used.
