B2B Battery Charging Disaster!

[Teutone]

Thanks for your comments sparrks and kevina. The Sterling B2B does indeed have an AGM setting so, assuming Sterling know what they are talking about (and I think they do), the Banner AGM batteries shouldn't be a problem.

As for the wiring diagram, I'll get this checked out (I don't speak German). However, I have spoken to a friend who is an electronics engineer, he looked at the wiring diagram for the EBL99 and pointed out which internal fuse has probably failed, with luck this is all that is wrong. He also said (translated into language I understand) that the output from the B2B has backed up into the EBL99 thus causing the problem. A diode should have been put into the cable between the EBL99 and LB, this may be what your German translation is saying.

Thanks again, I'm now understanding what's happened, what I've got to do to fix it and how to stop it happening again!

Beware, there is NO mention of a diode in the german document. I am not sure if it's clever to use the manual of a DIFFERENT manufacturer to wire a sterling product.

My German campervan also has a EBL99 fitted. I always wildcamp and my solution to low voltage on the leisure batteries was a 100 watt solar panel and a plug and play controller (made by the same company who make the electroblok).

I also have a Honda 1000 watt generator as back up (unused for 2 years).

The solar set up is great, when the van is stood for weeks the batteries are always full (incl the starting one).

When camping in it the batteries charge up at 14 volts during the day.
