Recreational Vans
Most mobile Starlink setups center on the rectangular standard dish paired with a router. In typical weather, the combined draw averages about 50 to 80 watts while brief peaks can push higher during boot, updates, or thermal events. The high performance dish draws more, often 110 to 150 watts under load, which matters when you plan an energy budget for a van or overland rig.
What drives these numbers up or down is not just the antenna. Ambient temperature, wind, and sky view change tracking effort. Snow melt can engage when the dish detects buildup. Routing hardware can add another 6 to 15 watts, and mesh nodes add more. If you power Starlink through an inverter from a 12 volt battery, conversion losses usually add 8 to 15 percent on top of the measured AC load.
A good baseline is energy per day, not just instantaneous watts. Multiply the average draw by hours of use. For a standard dish averaging 60 watts over 24 hours, the daily energy is about 1.44 kilowatt hours. If you only need connectivity eight hours a day, the same system consumes roughly 0.48 kilowatt hours, which is a very different storage requirement.
Expect 45 to 90 watts for the standard dish with router in fair conditions, and 110 to 170 watts for high performance gear. Boot cycles and heater use cause short spikes. Your number will vary with sky view, temperature, and whether you run additional network devices.
Heater engagement, obstructed horizons, frequent roaming, and unnecessary mesh nodes raise consumption. Good sky view, stable mounting, modest ambient temperatures, and efficient DC power feeds pull numbers down.
Use an inline DC meter when you run a DC integration or a plug-in AC meter on the power brick. Let the system settle for at least 20 minutes, then log average, peak, and daily watt hours over several days to capture real patterns.
Power planning for mobile connectivity starts with energy budget, then storage, then charging. Begin by estimating your realistic daily hours online, not worst case. Multiply the average draw by those hours to get watt hours per day. Add a buffer for weather, backups, and occasional overnight uploads.
Battery capacity should be sized in watt hours, then translated to amp hours at your system voltage. A 2000 watt hour target equals about 166 amp hours at 12 volts. With lithium iron phosphate you can safely use a large share of rated capacity, but it is still wise to keep a reserve for heating, refrigeration, and lighting. If you run high performance dishes or all day connections, bump storage accordingly.
Charging sources complete the picture. Roof solar contributes in sunlight with harvest shaped by season and latitude. Alternator charging through a DC to DC charger provides dependable energy while driving. Shore power is the fastest way to recover after long sessions, but do not rely on it if your travel is mostly remote. The right mix means Starlink is just one load among many, not the one that dictates your entire system.
Lithium iron phosphate offers stable voltage under load, deep usable capacity, and long cycle life that suits frequent connect and disconnect cycles. For most rigs using a standard dish part time, 200 to 300 amp hours at 12 volts is a workable floor. Heavy users or high performance dishes may need 400 amp hours or more.
Running Starlink through an inverter adds conversion losses that compound over hours. A clean DC integration trims waste and can save hundreds of watt hours per day on long sessions. Keep wiring short, sized for current, and fused correctly to maintain efficiency and safety.
Daily solar harvest varies widely. In summer sun, 400 watts of panels might yield 1.5 to 2.0 kilowatt hours, enough to cover a standard dish and basic house loads. Alternator charging at 30 to 60 amps while you drive backfills deficits on cloudy days and reduces battery depth of discharge.
There are two levers that cut Starlink power use without hurting reliability. The first is duty cycle. Run sessions when you actually need data, then power down between windows. The second is system efficiency. Eliminate avoidable conversion losses and extra devices that sip power around the clock.
Smart scheduling is simple. If you work eight to ten hours a day, align connectivity with those blocks. Overnight, shut down the dish and router. If you need background services, consider a low draw cellular hotspot for notifications while Starlink rests. Keep the dish clear of snow and shade to avoid heater and tracking effort. Mounting that preserves sky view prevents constant repositioning.
Network hardware choices matter. A single efficient router beats a router plus mesh when you are in a van sized footprint. Place the router close to where you work and sleep to avoid booster nodes. When you need additional range outside the vehicle, enable mesh only as needed. For video meetings, use wired Ethernet to devices where possible to reduce WiFi retransmits and improve quality per watt.
Batch uploads, updates, and downloads into planned windows. Cache maps and podcasts before travel days. Shut down the dish during extended drives if you do not need live navigation or streaming, and let alternator charging refill the bank.
Pick one efficient router, disable extra radios you do not use, and skip mesh unless your living space truly requires it. Each added radio adds idle draw all day.
Elevate above heat soaked roofs, avoid midday radiant hotspots, and give the dish a clear sky view. Clean surfaces so heaters rarely need to engage, and route cables for minimal voltage drop.
At this point, your path forward is clear. Calculate daily energy, right size storage, cut conversion losses, and use connectivity with intent. The result is a dependable link that does not own your batteries.
To bring all of this together in a cohesive system, professional integration helps. Vehicle electrical environments are dynamic, and correct DC wiring, fusing, and charge control keep everything safe and efficient.
