She Cannae Take the Power Cap'n!

Hurrumph....

Automotive blade fuses... PAH!

Don't use 'em.

I had my new batteries connected to the main bank with an in-line blade fuse holder and a 30A fuse.  Not a cheap-o rubbish fuse holder but an RS one.  It was the day after the longest day today and the sun was beating down after I'd more than half drained the batteries watching movies last night.  Pulled 6.4kWh from the system :D.

Today though, the secondary bank was very greedy and spent quite some time sat at about 25-30A charging.  The poor little blade fuses couldn't hack it.  Two of them melted (the plastic holders - not the fuse wire!).

So I replaced the in-line fuse holder with an old 32 Amp MCB breaker that I got at a car boot sale a while ago.  It's better that way any way as it can disconnect the battery if there's a fault and it also serves as an isolation switch.

The rest of the afternoon's sun was soaked up without further melting or burning of plastic / rubber / fingers...
