When im plugged into shore power and switch unit to charger only my 240v goes off every few minutes. Then resets itself. If i switch to i verter 240 power stays on but the unit switches between charger and inverter every few minutes. Also the alarm light comes on. It makes me think its shore power issue but then why would it come back on? Any advice appreciated.
Could it be that there is a current limit on your shore power connection at some campsites and maybe harbors too, they use special plugs where they can set the maximum current if you go over this, then it switches the shore power off for 10 sec and then switches it on again
Thats a very good point. We have had a boat at same place for years and never had issue. I think it maybe me not knowing enough about the system yet. I am going to put tester on shore power tomorrow an see if any fluctuation in voltage it gives.
If it is shorepower limit as @JMEIJERS states then there is a setting in the Multiplus to limit shorepower current to stop this happening, but it is messy to keep reprogramming it. If you have a Multiplus control panel or GX device, you can set the limit to be “over ruled by remote” so you can adjust it easily from either device.
That could be the answer. Where it was moored before may have had lower shore power then we do, so unit is compensating for something it doesn’t need to. Our shore power is 10 amp i believe. So do i need a controller to program it or can i do it on the unit? Thanks for your help all
You either need either
- the mk3 to usb interface and either a pc / laptop with ve configure or a smartphone with usb port and Victron Connect app
Or
- The Multiplus connected to the internet and VRM through a GX device and a laptop or pc with VE Configure.
I have a multiplus control panel that came with the boat, isnt connected but i can do that tomorrow. Then i need to alter settings as you said above still? I will see if i can get the mk3 cable somewhere soon. Thank you
You may still need it to set the “over ruled by remote” to on, I have no idea what the default settong is. Perhaps connect the panel and see if it works.
I agree, I shall connect it tomorrow after work and see. I found a few pages of a manual in the folder, says something about switches inside the unit. Il see what i can find out about that tomorrow. Thank you for your help, i will update the post when iv connected and tried the controller.
