I may be wrong but, by the look of the setup, you don't have one central busbar to terminate all three batteries, you seem to have done nothing more than move the connection point on each battery down to underneath then reconnected them back up in parallel, or am I missing something
Hi Mick. Thanks for the comment. Yes, I think you’re missing a bit here. Have you watched the video prior to the series just released? The central busbar is all the cabling and busbar connections below the cabinets. The reasons for the busbar system was to even the load on each battery and to be able to isolate each battery individually. There is no need to isolate all 3 at once, so I have put the inline fuse between the inverter and busbar. If I wanted to isolate all 3, I have 3 breakers instead of 1 master breaker (if you will allow that term). This takes about 2 extra seconds to turn them all off and allows me to disconnect a single battery from the system if it needs maintenance. The previous setup worked, but was drawing power unevenly, draining battery 1 faster and reducing the useable capacity. This new setup is so much more functional than what was in place before. I hope that answers your question. Are you considering something similar?
you have connected battery 3 busbar to battery 2 busbar then those two to battery 1 busbar, then to a fourth busbar then to the inverter, is that correct,
@@mick.Walker No. You might be getting mixed up because the location of the Battery 3 breaker is on the right hand side of Battery 2 cabinet. It's better to see the breakers as 1,2 & 3 and ignore the location of them relative to the cabinet they are mounted. The breaker 3 location was chosen to allow for a fourth breaker to be placed to the right of it (left side of cabinet 3) if I decided to add another battery. 4 batteries would fit inside the 3 cabinet space with minor changes needed. You will see at time stamp 14:00 that there is a partially cut breaker hole for a fourth breaker which I decided to patch up having decided (for now) to not get a fourth battery. Each battery has its own breaker and then each breaker connects to the busbar system below the cabinets which then runs to the inverter, which in turn has a 150A inline fuse on the positive cable.
Don’t be. A single anchor is more than enough to hold the weight of the cabinet and battery. I’ve put several into each cabinet. Just as an example, the worst M10 bolt will hold 200kg with proper anchor bolts holding many times that before sheering. The reason for adding more bolts is to spread the load across the wooden structure.

Hi where did you get dc isolators boxes from I have a similar setup to you
Amazon sell them
@@GaryMeatsLifethank you
I concerned on the weight, relying a lot on those wall anchors.
