"Hi Peter -
Just a short note with some very positive feedback on the 12-volt system that you designed for our sailboat wayback in 2005.
We use the boat for 4-5 months each year from December through May, cruising in the Mexican Sea of Cortez (Sonora and Baja California). We spend roughly 5-6 weeks in remote anchorages and the rest of the time in marinas in San Carlos , Sonora and La Paz, BCS. Then we put the boat in dry storage, exposed to the desert heat in San Carlos from May through November - a stressful half year for any battery system.
You designed our system with four, 6 volt AGM house batteries, a 12volt Optima Redtop starting battery, a two switch Blue Sea switch, a 30 Amp Victron Charger, a Balmar 100 Amp alternator, Balmar voltage regulator, an Echo Charge device. I added solar about 9-10 years ago, first 2-80 watt Kyocera panels, then two years ago a pair of 160 watt Grape Solar panels and 30 Amp controller. I disconnect the large solar panels during the summer layup and connect a tiny 0.5 Amp panel to keep the batteries topped up.
The good news is that the AGM batteries lasted a full 11 sailing seasons. I never had to touch them during all that time. I admit to some suspicion that they were losing compacity last season. But they always provided more juice than we needed. This year (#12) when I commissioned boat they failed a load test and are requiring replacement. The Redtop is still showing good performance characteristics.
Not bad performance for AGMs !! I credit your design for that."
