Blog Review: Lithium Battery System

Hi Mick,
Thanks for the compliment.
It's not as complicated as it may seem.
Before the change I had my solar in series, one single string. Just changed the wiring to give me 3 strings instead of one.
The charge side is almost the same as it was before, the only addition being the DCDC charger. All charging sources should have the ability to be adjusted to match battery supplier settings.
The Bluesea safetyhub just replaced a plethora of individual fuses/CB's. The pos and neg busbars replaced a couple of power posts.
The packs were the main difference but not hugely, as well as the battery control unit.
A different mindset is also required if you are transitioning from AGM.
Don't be overawed though.
Cheers, Bill

Stephen,
Yes, each pack is 160 A/HR for a total of 480 A/HR.
I scratched my head too as to why each pack needed a separate feed and C/B on the positive cables but the supplier said it was required so that was it.
They did say that if I have a problem with one pack it can be isolated even disconnected and the other two can still function.
If you go to their website you can see schematics for various configurations and where there is more than one pack, there are separate feeds.
Cheers, Bill
