A few more questions about solar panels...

I’ve been there with faulty controllers before, so I totally get the frustration. I recently upgraded my system and ended up using a controller from solarsmart.ie, and they were really helpful. I had an issue where my panels weren't charging correctly, and their support team walked me through the process of figuring it out—turns out, I was using the wrong type of cable for my panels! After swapping it out, everything worked like a charm. They’re pretty knowledgeable about different setups and have great customer service if you need any advice.
