Victron losing mains power

[Boomslang]

Hello Canalworlders,

 

If I flush my toilet (12v) or run my water pump for more than 3-4 seconds my Victron multiplus (12/2500/120) changes from mains on/float to low battery. I lose my 240V and my 12V.

 

I'm sure more info will be needed to diagnose but does anyone have any ideas?

 

Cheers,

 

Jared

Your batteries are very, very flat. OR you have a bad connection to the batteries.

Are you connected to a shoreline ?

 

Do you have a multimeter ?

 

Test 1) Can you test the battery (across the terminals) and see what voltage you are getting.

Now

Test 2) Test across the battery terminals whilst someone runs a tap and see what voltage you are getting.

 

Report back here with the voltage results.
