Connecting 3 banks on the 3ph is not recommeended. You should Read the manual. All depends on voltage and disconnect current

Hi Daromer,

thanks for reply, but what do you mean with 3PH, doesn't ring a bell.

I planned to intall two parallel Battery banks with each 14S and I would like to connect both positive connectors to the ABB S5,
to switch only the positive side in case of an emergency.
The advantage I see is, I can do Maintanance on one Bank while the other Bank is still connected.

3 phasr/pole versions. They have diagrams on how you are allowed to hook it Up. This to make sure it protects your system properly.
I have 1 breaker for each bank. Then on each bank i have 1 switch per string so i can do maintenance on a string in a bank.

Hi daromer,

OK, I now understand.
Unfortunately I was not able to find a Manual for the SB5, do you know where I can find one?

If are using an external BMS to control the shunt, then would we not achieve the same thing using a Victron BatteryProtect 48V-100A 
This has a remote port which you can connect to the BMS for a remote disconnect ? You would obviously need a mains breaker for isolation all the batteries,
the added advantage is you can then remotely re energize your batteries if you have identified that its a false positive or the back is now balanced and safe to re-enable ?


UPDATE: RTFM I have just looked at the manual and these units only allow current to flow in 1 direction so connecting to an inverter which charges will damage the unit

If you are referring to the Victron Battery Protect... you are correct, it is a direction device.

Its application/use case is to manage the load, but it also doesn't like surges and is not compatible with all inverters. Its a device that plays very well in the Victron ecosystem where that device is allowed to control others.

Will Prowse has a video of its use, but was later corrected by Victron. This is documented on his forum. I dont remember all the details but you might want to look into it. Its based on this outdated video which uses the product incorrectly.

Here you go... this was the thread I wanted to share about the Battery Protect

Unfortunately that is just the going price of NEW branded circuit protection.  

While a lot of this gear isn't cheap, the used market is good place to look.  You may have to make some compromises, but there are big savings going used commercial/industrial electrical hardware.

I highly recommend you look at eBay along with other liquidators of used equipment. 

I bought mine off ebay but have this bookmarked after I saw another member with this info in his signature.
