PS2DC + Triple Shunt (FLEXNet DC Monitor): Possible?

Post by BoggyScott »

I love the innocent little diagram on the FLEXNet DC Monitor spec sheet showing three shunts bussed together.

Is this configuration physically possible inside a PS2DC enclosure? (Single inverter, at present.)

Thanks

Yes, it is possible to mount three shunts in a PS2DC. The positive bus bar will need to be moved the mounting bumps near the inside edge of the PS2DC. While there are no mounting "bumps" to attach the additional shunts, you can attach a BBUS to position the three shunts in a "T" pattern, re-install the original shunt, drill starter holes for the additional shunts and then use self tapping or thread cutting screws to secure the shunts. I epoxied some small washers on the additional shunts to compensate for the height difference of the original shunt's mounting on the "bumps".

OK, well, good/bad news there. Obviously it's coming off the wall. <sigh> But come to think of it, that would be the case even if the mounting arrangement was predrilled. Thanks for the info and especially the tips. A photo or drawing would be mucho appreciato.

Even with just one inverter, my PS2DC is so full, I will not be able to add two more shunts. I think I will leave the one in there and bus the other two and some additional DC breaker space from a PSPV or MNPV6 or some other box. Plus, I really did not want to take apart the whole DC side on my system...
