Please forgive me as I’m no electrician. I just have a question about the safety of my fuse on my leisure battery terminal.
I have a self converted (not by myself) campervan.
Set up wise it has:
120w eco-worthy solar panel x 6
Victron Multiplus 2 12v/3000w
Victron 100/50 MPPT
Victron Orion TR smart 30a x2
Victron Lynx Distributor
And runs on a Fogstar 560ah lithium battery.
The other day I was running my air fryer, which I use regularly and have no issues. However it was a hot day and I forgot I had the air con unit running also. (Truma aventa compact unit if that matters).
The inverter duly overloaded. After letting it cooldown and resetting it. The inverter will now only power on with the dc-dc converter or the solar panels.
After inspection, the fuse on the positive battery terminal has blown and needs replacing.
It is a blue sea? BUSS rated at 250A / 58V.
My question is, is this the correct size fuse? As when I have been looking for a replacement fuse, most sites are recommending a 400-500A fuse for that size inverter/battery setup.
Many thanks for any help you can offer.
