Load control LVD

[PKsolar]

Oops! All thumbs folks. Let's just start this again.

I meant to write LVD Low voltage disconnect in the "LBD" topic. I also just read in October blog from Spokane that neutral is switched. I have my negative from Kid load to neutral (negative) bar in MNS mini box then out to relay coil with positive.

Bad idea? So if I make my own separate negative buss bar from the Kid Load, then send it off to the relay/s with the positive (coming off a 10A breaker), Have I made things work? I'll try tomorrow and let you all know...

I nuked the thread with the typo to avoid confusion.

OK, I was correct in the first thread I started and was nuked. You do call it LBD (low battery disconnect) in the manual. NOT LVD. Anyway, thanks to another thread I read... Yes, the disconnect takes place on the negative side. So once I took the wires direct to the relay, it all worked fine. The fridge and Lunos HRV now run off the garage's smaller array/battery then switch to larger house array/battery when LBD says it should.

Now, where in the manual does it mention you need to wire the loads to be switched by negative? Please put that information in the LBD paragraph where it should be.

There's also plenty of space in the wiring photo to put a balloon text with arrow at the load negative that reads "LBD switched" or something in that order. It certainly would curtail confusion/frustration.

All in all I love my classics and Kid:) Our only utility bills are when it's dark and cold from Dec-early Feb here in NE WI and that's only for backup floor heat. Solar does the rest when it's sunny.

PK;

LBD and LVD I understand  the point of confusion.

LVD seems well recognized in the industry to indicate disconnecting loads to protect batteries.

Having said that, this is why we discourage undefined acronyms and abbreviations in posts. Documentation writers should, as well.


I nuked the original as it appeared to be what you wanted.

The switching the negative lead is also rather common for technical reasons which I am not qualified to properly explain.
