Loving the setup... One thing though. Your MPPTs should be connected on the right hand side of the Lynx Shunt (Lynx Power In that you have the inverter cables on). Only batteries should be LEFT of the Shunt so as to get accurate readings.
@@Gridbusters-qx4om I was also going to mention this, but see someone beat me to it. Don't feel stupid, we all need to learn and there is a lot to get your head around. You might well want to brush up on what data cables connect what, as Victron use a multitude of different data cables.
You actually don't need the shunt as you could be connecting (VE,Can/VE.Bus) the CerboGX to all the various pieces of hardware (MPPT's, Battery, Quattro) that way the Cerbo can control and also monitor input and out out of power from the hardware. I don't have a shunt and have added a Grid Meter to my Grid feed to monitor this as well.
@@maritzm That is true, so long as the batteries play nicely, as they will be reporting the SOC charge without a shunt. My advice would be to set it up in the correct order, then you have the choice of using the shunt or batteries (BMS) for reporting the SOC.
Enjoying watching you do your install, I completed "for the moment" my install about a month ago, and I love looking at the stats on the victron system, that and the system is rock solid and handles everything I have thrown at my MP2-5K, very reliable. Looking forward to your continued progress :)
Good to see you doing another video and the lighting is great. Can't wait to see you start making power. And it not boring to watch you hook up cables and fuses and even the mistakes.
Fuse on top would make the fuse easier to replace. Thank you for the video. I enjoy every little thing although I am sorry if that means you can't listen to the radio.
Hi. Where you connected the batteries comes without fuseholders for a reason. You modified it and this is one of the reasons why the nut at the back side turned when you were tightening. Remove that modification and fuse the batteries as recommend by Victron. On the right side of the shunt you should use a Lynx Power distributeur. This has proper fuseholders made by Victron. Spend a bit more money to get the proper equipment. It saves you a call to the fire brigade.
Crimping further down stops the flaring at the bottom but I think the trouble Sarah is having is the metal that gets pinched out to the sides. It happens when the terminal is squeezed and excess metal gets between the dies of the hydraulic crimper. I was dealing with the same thing over the weekend and solved it by rotating the terminal 60 degrees and crimping again which flattened the excess against the rest of the crimp. Sarah does seem to have much more excess than I was dealing with so it might not work for her.
No I think your fuse was right the first time, as replacing them would be made much easier if they are on top of the terminal. Its only when terminals are clamped down onto a battery terminal that they should be sandwiched between the lug and battery terminal. Does not necessarily apply here at the fuse bank!
I've seen other people wiping the contacting surfaces clean before connecting things. It might sound a bit OCD but since most of those connections are only going to be made once it might be worth considering. What are other viewers' thoughts on the matter? Any suggestions of what to clean them with?
Your charge controllers should be connected to the right of the shunt. You want to monitor all the current flowing in and out of the batteries. Film it all like watching. Thanks very much.
I think the charge controllers are connected on the wrong side of the shunt. You want to know the current/power going in an out of the batteries Unfused cables going to the inverter ? 14 Nm looks way to much for the fuses. What did the specsheet of the fuses recommend? Never put annything between the contact surfaces. iron is a bad conductor, it will get hot at high currents!
If you want to monitor the charge on the batteries using the shunt then ONLY batteries should be to the left of the shunt and Quatro and charge controllers shud be to the right of the shunt !! I don't see the required fuses on the Quatro DC cables yet !!
Why the inverter dont have his own fuse? Is there no fuse inside your batterycase? Maby you can put you shunt to the left and connect your battery's on the shunt?
as i watched the last few min of your video i realized you have connected your charge controllers to the downstream side of the shunt. They can charge the batteries without going thru the shunt. With the shunts i have used they need to be between the battery and everything else to monitor all power in or out of the battery. Does your system work differently than this?
I’ve been an avid fan from the start but I’m finding your solar setup is becoming on a scale i can no longer connect with financially, Sunak, Elon come to mind! I need some context on how this is viable financially for most people! The money spent for a domestic supply would take ROI of 2 life times from my basic maths so would workout cheaper to just use grid! I like to dream so do enjoy set ups beyond my lifetime finances including grid scale! Anywho, Great you included some errors, it keeps it pedestrian for me! Lol ❤

You caught that right. Had to go check my shunt.😅 Inverter/charger/MPPT must be connected after the shunt.
Absolutely agree I feel really stupid I need to redo this well spotted.

It's really shaping up, looking great all around. Can't wait to see the thing operating!

You and me both!

Very interesting to see how you connect the cables.

wow good you show wrining control ac in ac out and pv solas and show set up paramiter inverter .
The 250V is quite okay ^^. They are there to protect the CABLE and yours is atleast rated for 200A * 1.25 = 250A.
Good video. Good to see the progress.
I'm wondering about the cable. Isn't 95mm² a little generous for only 150A?
To get rid of the ridge, just crimp it again further down the fitting.
Crimping further down stops the flaring at the bottom but I think the trouble Sarah is having is the metal that gets pinched out to the sides.

Unfused cables going to the inverter ?

Yes the charge controllers should be connected on the output of the shut to be able to measure the output of the chargers into the batteries
If you want to monitor the charge on the batteries using the shunt then ONLY batteries should be to the left of the shunt and Quatro and charge controllers shud be to the right of the shunt !! I don't see the required fuses on the Quatro DC cables yet !!
Yes absolutely this was a mistake on my part I'm correcting this in the next video.
Why the inverter dont have his own fuse? Is there no fuse inside your batterycase? Maby you can put you shunt to the left and connect your battery's on the shunt?
yes next video i will put that fuse in...

Well spotted... When I realise I completely screwed up and need to redo this wiring...

Link for the torque wrench ?
I'll dig out the link for you tomorrow it was on Amazon in France
Wrong work. Thinks Thatcher the shunt function
