My 5-year old Lake Lite solar panel and regulator wasn't charging my brand new battery. I spoke to the people at Lake Lite and after trying a couple of things to fix the problem, they suggested getting the new rewiring kit. I am very glad I did! This new kit is much more robust than the previous generation and the regulator has more features that can aid in finding any future problems I may have in charging the battery. Installation is very easy and I highly recommend it for anyone that is having issues with their current regulator. I'm also glad the new kit doesn't require the hard to find glass fuse that was needed in the older model. This is definitely worth the money.
