I'm starting this review with my most recent interaction with Tim Gailey, which was yesterday. Though I purchased and installed the materials many months ago (two flex solar panels, a custom made frame -which Tim measured for and then had someone else build, a 253AH lithium battery, a charger, a controller), I found myself in need of Tim's expertise yesterday and texted him. He called me a minute later and we spoke for quite awhile. The problems I desired his help with occurred during my weekend sail to Catalina and had nothing to do with my BellaLexa equip. and yet he happily helped me to understand what was occurring with some interfacing gear, and his willingness to do this says everything about him! I'm now much clearer about what these problems are, and his generosity reminded me again of my every interaction with him from the very first. Tim had the equipment I needed, visited my boat on several occasions to verify, and then guided me in doing my own installation. Having ample solar and battery capacity in such an efficient and affordable footprint has completely transformed my 42' sailboat. Thank you Tim!! G.Hemwall s/v Wippy Marina del Rey, CA
