Loose terminal blocks inside Samite DB?

[LightsOn]

@lights on' I had a project just like what you are trying to deal with 2 years a ago, I stripped all the extras, installed 1 surface 3 tier DB over the flush DB, cut a hole into the back of the 3 tier DB and rerouted all the wiring to the new section in the new DB.

I feel such gratitude for your feedback.

I came here to mention the idea that I had, of riveting a 1mm thick sheet of aluminum to enclose the bottom right corner of DB1, such that the geyser and lights wires would be totally inaccessible and invisible in DB1, and would exit the right side of DB1, going into adjacent DB3.

But the multi-tier surface mount DB idea is just so clean and will be easy, straight-forward to CoC without complications and issues.

There is also value in replacing the complicated mess with a single DB.

So I think it's a winner.

At this point I'm thinking to replace DB1 and DB3 with a single 2 tier surface mount DB.
It would be the cleanest to have a 3 tier, and relocate the batteries and inverter close to the DB, so that all alternative supply stuff can flow out of a single DB.
Because currently the batteries and inverter are far away, so the current tentative plan is to have a DB2 at the inverter that does EL, and that has a cable run that feeds the main DB and some plugs along the way.
I'm reluctant to move the batteries and inverter to near the main DB because then they'd be far away from possible PV panels which may be added in future. Long PV wire runs are inefficient. It's only a 12v system.

If you have any further thoughts I'd be very interested.

I will discuss the main DB replacement with my contractor.

I replace the single tier DB's with 3 tier DB's when installing inverters.
I split the essential (top row) and non essential (bottom row) and use the middle row for the "electronic relays and that stuff. Label, label and then label a bit more just in case. It is practical and look neat.

I'd love to see a picture of one of your completed 3 tier DB's, sounds amazing.

While doing more research into Victron products, I noticed the multiplus unit, in some cases a 3 tier DB would be required.

It has an input and 2 outputs.

So you could use the top level for input/output (grid), the middle row for output 1 (high power) and bottom row for output 2 (UPS).

What I did learn this weekend, why it is so important to do brand specific training and not just some random solar course.

Even if you install simple inverters like Axpert branded inverters with FLA, gel or AGM batteries, you need to understand the setup parameters, other you going to be replacing batteries sooner than you think and your system will not operate to its full potential, more likely increase your electricity account.

100% agree ! I have taken to Sunsynk to learn as much as I can and be my go to inverter.

However I am also doing work with a Victron guy so getting good learning in that.

One thing for me with Victron is the one pro is that it is modular but con is that it is modular haha. Just something about all the extra work that could be in a box... But also here I am taking domestic, modular has huge huge plus in commercial or bigger things.
