Just purchase a 24/3000 70 and waiting for delivery. My plan is to add a few pieces at a time as I slowly build and increase my off grid cabin. Although posted elsewhere, I included a schematic of my system. I do have a couple of questions out of curiosity as I was planning on differing from the manual (a collective gasp falls across the forum.......)
1. I am using 2/0 cabling -50 to 105 C welding cable rated at 300 Amps (depending on what source you look at).
2. Thinking that I will fuse at 200 A into the inverter and not the recommended 300 amp fuse. Any reason not to - I know fuses can run hotter closer to their 'breaking' point but I will only be running at 117.6 Amps (max DC).
3. Since I have a floating neutral generator I will be turning the ground neutral relay off. The main G-N bond will be in the main panel. There is no grid to connect to - I'm 21km / 13 miles from the nearest power - and running poles is expensive...). My understanding is that if power in (shore or generator) is detected the relay would turn off automatically leaving the system unprotected - I do not want this to happen.
4. Looking at putting a pre-charge circuit in similar to what filterguy posted. It would be nice to mount the switch directly to the Lynx power in - any tips or tricks on this one (i.e. switch brand / type).
5. Last one - Lynx T-Class: I guess it's a good idea but trying to figure out if it defeats the purpose of have the fuse close to the battery terminal. With bigger battery banks I believe cabling would get to be long in order to keep equal length cables. Any comments on this?
Was also skeptical of the 1000A Lynx Distributor rating given the busbar dimensions - then I found this in the Victron Community:
“No, the Lynx system cannot do 1000A continuous without active cooling. We have calculated that 500A continuous current can be maintained using the vents on the Lynx products in a room-temperature environment. But, if you are smart about distributing your batteries, sources, and loads relatively evenly across the Lynx bus, you can keep your local currents down to 400A-500A.”
@sunshine_eggo - curious on your comments here.
Thanks for posting about all this Eurotrash guys - I fell for the click bait.
