New Dutch ESS , 3 x Multi RS + 48Kw

[KEMA (Martin Jansen)]

Finished my home install, works like a charm!

3 x Victron Multi RS 6000/100/450
3 x EEL Battery (16kw LifePo4 each with Seplos 3.0 BMS)
1 x Cerbo GX + GX Touch 70
2 x VM3P75 3-phase meters (1 grid + 1 solar)
Lynx Distribution, Lynx Shunt, Lynx Power (M10)

I have a total of 24 Solar panels producing 10400 WP with devided over 3 Phases with Enphase iq7A inverters. I have a Tiber dynamic contract and use a heatpump (8kw) for heating the house and water. Also 2 electric cars that charge dynamically as well.

DESS works prety good, although I plan to program something myself using node red soon.

How did you connect between the shunt and the lynx power in with the batteries’ input?

[KEMA (Martin Jansen)]

I made custom busbars from a solid 0.8mm thick copper strip with M10 holes.

Thank you. Can you share a picture?

I have been looking for such a solution. Connecting 2 Lynx Distributors/Power Ins with Opposite Direction Cable Entry

[KEMA (Martin Jansen)]

Not at home atm, but it looks like this:

I ordered it here: Roodkoper platstaf - Snel Metaal

I selected 20 x 8mm with 500mm length. Only needed to drill the M10 holes myself and cut them into the right length (9cm in my case)

[KEMA (Martin Jansen)]

Oh, and I changed the red and black covers at the end of the power in unit, so ultimately changed the positive and ground around (i.e. positive wires under, negative on top) to match the bars on the distribution side.

Hey Martin, system still going smooth? Nice set-up

can I ask you a couple?

Why do you use a shunt, is the info from the battery not available?
What is with the aluminum shielding? Noise? Heat?

Tnx Michael,

The shunt is basically used as a slightly intelligent master fusebox, I don’t actually use it to measure. I use the batteries BMS-es to do that, connected via CAN.

The aluminium shielding is to put an extra layer that absorbs both noise, and damps vibrations a bit. The RS-6000’s are relatively quiet anyway. It also gives an extra layer of protection against heat on top of the fermacell plates.
