So I have 2 12V GEL batteries connected in series to a multiplus compact 24V/1600VA/40A. The multiplus reads 16V, so it triggers the low voltage alarm and sends every bit of power to the batteries when they are fully charged. I also have connected a BMV-700 and a CCGX to monitor the situation.
I have tried enabling DVCC so that the BMV shares its reading with the multiplus but I haven'yt been able to make it work.
What are your suggestions?
Is the multiplus dead and needs replacement?
How can I make the DVCC feature to work correctly?
