UVLK reset

[sailingharry]

Dacian,

I don't use the UV on my system.  I do use a Type 4 to shut off my inverter, the largest and easiest load to disconnect, but beyond that I use the gray matter between my ears to keep my battery on line.  UVLK is the backup to that.

I recently sort-of-intentionally ran my battery to the point that the UVLK tripped.  All went according to plan.  But, that led to a connundrum -- how to charge it.  My "Charge" contactor has a manual override, so I turned it on.  Then, most of my charge sources are controlled by a Victron Battery Protect (a Type 1 device), and it seems a Type 5 also trips Type 1 (I get the logic for that), so I had to put a jumper across the BP to get it to conduct.  80Amps going into the battery, voltage starts to rise, all is good.

My SBMS0 is mostly stock settings.

But, I have two small issues.

1)  UVLK trips at 2.5V.  It was probably around 3V that the Type 5 was released and normal charging was allowed.  (Maybe 3.2, Under Voltage Recovery?).  I'd like to change that so it doesn't take an hour to get the system back on line for normal charging.  A more appropriate recovery would be 2.75V (it's not going to come back up on it's own-- if I'm at 2.75, I'm clearly taking corrective action!).  I don't want to adjust Under Voltage Recovery, as that's a normally activated setting.  Is there a way to get Type 5 to reset at 2.75V?

2)  A Type 5 LV is unusual, but possible.   Is there an easier way to enable charging with Type 5 set?  Maybe change one setting?  I have to dig under stuff to get to the physical override on the contactor.  Maybe I should make up a "recovery" harness, that makes it easy to provide power to the contractor and enable the Battery Protect -- but that does seem excessive complication.

In theory, this situation should ONLY arise in testing types of scenarios.  Capacity test, system operation testing, etc.  So "ignore it, it's OK" isn't a horrible answer.

Thanks!
