My first post and I put it in the place. Sorry for mistake.
My problem today is with a Battery Protect: BP 12/24 / 220. Installed on a barge.
I returned this year to the boat and there was no 12/24 service. The 220v was fine. A man that works mostly with MasterVolt mentioned he had seen this before and a temporary solution was to connect the 2 cables coming to the BP together. He used the “In” post on the BP but I assume that just bolting the 2 cables together would also give desired results. Obviously the BP is not protecting.
A little back and forth with the man that installed this (400 km away) I was sent a new BP. I can not get the unit to program. So with a fresh re-read of the instructions let me tell you what I have done that does not work.
Connected the 2 cables to the Out and In posts
Removed the remote plug
With a wire I connect the Program slot to the Ground slot.
I want to use the “4” setting and allow unit to cycle and remove the jumper wire.
I get an “E4” error each time I try.
I was told the above must be done when the battery readings are below 27.6v (less than the “4” setting).
The above is also what I was told to do but reading the instructions makes for some questions.
Should both the Out and In cables be connected to BP when I re-program?
Must I set the voltage “d” before I set the under voltage Shutdown and Restart? I don’t recall seeing “d” flash by. How do I get it to display to select?
I have a Venus GX, an Apple 7 and Victron Connect app on the phone. Can I program the BP using the phone?
From other post here I offer this information: I have an inverter and run 220v on the boat. Do I need a BP?
Reviewing info from Victron Connect app, I see that there was a time, I don’t know when, that the 2 sets of batteries (engine and boat) show a minimum voltage of 6.5 and 4.15.
I have a nice Victron set-up on the barge. I am electric independent, never needing to plug in. If I can get this solved and another issue I will sleep better. Appreciate any guidance. Will be a lurker here.
