Several months ago I purchased a Victron SmartShunt 500A off Amazon. About 6 weeks ago I finally installed it. It worked the day I installed it just fine. I was able to connect with the app and look at the settings. Weekend before last I went to the building and tried to connect with the shunt and the app could not locate it. I finally figured out that it had no power, the fuse was blown. I purchased new 1 Amp Slow Blow fuses (glad I got more than one) and tried to replace it last Saturday but it kept blowing the fuse immediately. I tried 3 times with the same result. I even turned the entire system (panels, charge controllers, and inverter) off including the batteries (Smart BMS's), replaced the fuse and then turned just one battery pack back on. The fuse burned through immediately.
I went to the Victron site and put in a Support Request detailing just what I said above. They forwarded my request to a dealer. Below is his response.
"I’m responding to the issue you're having with a blown fuse. That fuse is in line before the power gets to the smartshunt. Something from the battery must be causing it to blow. Its there to protect the smartshunt from a battery surge. A quick way to test this would be to take another battery and hook the smartshunt power cable to it and see if the fuse blows. Let me know what you discover."
Does this make sense to anyone? The battery is somehow surging too much amperage into the shunt and blowing the fuse?
Has anyone else experienced this problem?
Anyone have any ideas?
Thanks,
J.P.
