Outstanding products and customer service. I recently purchase 3-145 W Sunpower Shade Tolerant solar panels, 3-Victron 16/75 Controlers, and related accessories for my 38’ Sabre MK I Sailboat and am extremely pleased with the company and its personnel. Their website first attracted me due to its detailed explanations and overall guidance. Their sales/tech rep, Harrison, was patient, knowledgeable, and available in an “above and beyond the call of duty” fashion that is rare in the modern era. He stood by me through the entire process from initial guidance with assessment of energy needs and selection of proper components until the installation process was complete. He was always friendly, helpful, and available whenever I called (even occasionally on a weekend). I wholeheartedly recommend him and the entire Custom Marine Services to anyone considering a solar energy purchase and DIY installation on their boat.
