When we bought our CHB trawler "Vestri" in June, its off-grid power system was limited. It consisted of two 100W solar panels, a 15 amp solar charger, and 4 Trojan 6V batteries. Good enough for some boaters, but we are heavy power users, having been spoiled by our extensive off-grid system in the RV. The main extra draws are a second fridge/freezer, Starlink Internet Dish, computers, and an electric blanket for Anne. We also want to be at anchor for days even if the sun isn't always shining that well.

So, over the last few months, I have reorganized the wiring, upgraded the inverter/charger, installed a second (300Ah lithium) battery bank, and added more solar panels and power monitors. In this video, I walk you through my latest off-grid power system incarnation via a block diagram and then show the real-world hardware. It's just a snapshot in time, though, as I'm sure I will continue to tinker and refine it as we go.
