RigWatts: Off-grid power math for RVs and Starlink Mini
RigWatts presents six calculators for RV and vanlife 12V/24V power questions, from Starlink Mini runtime and wire sizing to diesel-heater battery use.
- For
- RV, vanlife, and overlanding power users
- Worth noticing
- The Starlink wire-drop tool describes a 60W startup surge and an 11.8V boot-loop threshold; the wire calculator cites a 3% voltage-drop target.
Field notes
The calculator descriptions identify variables that ordinary battery-capacity estimates can miss, including inverter idle draw, heater ignition spikes, and compressor-fridge duty cycles. The wire-sizing tools cite a less-than-3% voltage-drop target and 125% fuse rules; these are presented as the site's methods, not independently verified here. The homepage also links to troubleshooting guides for Starlink reboots and diesel-heater low-voltage errors.
