Victron Battery Protect

[Southeast Boater]

Hi there Canal World! 

 

I’m wondering if anyone can help me, I’d like to install a Victron battery protect on my Narrowboat to protect my batteries. I’m unsure of which model would be best suited? 65/100/220A? My battery bank is 4 x Trojan t-125 240Ah (480Ah 12v in total) although soon to be 6 x so 720Ah. 

 

I’m not sure what other information might be needed but I can provide it if need be...

 

many thanks! ?

There’s really no difference in the models bar the amount of amps they can handle.   For this you need to know what your batteries power and what amps they use, especially high powered items like if you have a inverter.   Battery config is irrelevant here.

I see so I’d need to work out what the maximum expected discharge current will be and purchase the relevant unit depending on how large that is. 

 

E.g. max expected discharge current 80A, I’d go for the 100A version?

Yep,  if you have something like a 3kw inverter/combi then you won’t be able to go via the protect tho.

 

if your adding the protect between your main fuse distribution board and battery, then usually (that really be a should be!) there is a main fuse as well, this would be the rating you need.

Slightly unsure of which rating to use? Would you be able to clarify from this picture please? Thanks!

Depends where you are going to put the protect.
