We use the compact NOCO GENIUS10 to maintain our car during long trips and have charged many dead batteries with it. Its 10-amp output, 6V/12V modes, multi-chemistry support, long leads, and Force Mode make it far more useful than a basic trickle charger.
When the batteries are full and the sun is still working, we dump the surplus into the water heater — free hot showers from power that had nowhere else to go. Here is the automation that runs it.
Our anchor light switches itself on at sunset and off at sunrise — legal every night without a second thought. Here is the simple automation behind it.
Free marine solar sizing calculator. Daily energy need + peak sun hours + realistic loss factors → recommended panel wattage. Tuned to what we actually see on Yoto in the tropics.
Free marine battery bank sizing calculator. Plug in daily Wh consumption, days of autonomy, and chemistry — get the right bank size in Ah. The same calculator we use on Yoto.
Free marine DC fuse size calculator using ABYC E-11 standards. Sizes fuses for continuous, intermittent, motor, and inverter loads — and warns if your wire can't safely handle the fuse.
Free marine DC wire size calculator using ABYC E-11 standards. Enter current, distance, voltage, and acceptable drop — get the right AWG every time. The same calculator we use on Yoto.
Three years with the Yacht Devices YDNR-02 NMEA 2000 Wi-Fi router on our boat. Reliable, simple to configure, zero drift. The only catch: the company is opaque about its origins.
The Victron SmartShunt 500A is the battery monitor we run on our boat. Here is why it beats the cheap alternatives and how it fits into a full monitoring system.
Most smart home gear is AC-only. Shelly devices work natively on 12V DC — wire them directly to your RV or boat system and control everything through Home Assistant.
