G’day. I’m Darryl. I’ve spent ~18 years building and commissioning solar and battery systems — remote off-grid setups, hybrids, the lot. Real jobs, real faults, real fixes. This isn’t a theory shop.

What I’ll be sharing: how these systems actually behave, the faults that catch people out, and the decisions that make or break a job. If you work with solar or batteries — or want to — pull up a chair. First question for anyone here: what’s the one solar or battery thing that’s done your head in lately? That’s where I’ll start
