A straight-shooting power calculator for food truck and trailer operators who want to ditch the generator — without getting a sales pitch.
Most "battery sizing" online either comes from a battery brand trying to sell you their largest pack, a solar installer working off a residential template, or a forum thread from someone with a different rig than yours. None of that gets a working truck operator to a reliable spec.
We built FoodTruckBattery.Com because the people who actually run trucks deserve a tool that:
In about five minutes you describe your rig — shift length, truck type, what's plugged in. The calculator returns running watts, peak watts, daily energy use in watt-hours, recommended battery capacity in kWh, and an inverter size with the right surge headroom.
It uses a published equipment database with real nameplate ratings, duty-cycle profiles tuned per device type, and the same NEC-style rules a licensed installer would apply for circuit sizing. If a unit is high-draw, we'll tell you. If propane is the smarter call for a specific item, we'll say that too.
The site is built and operated by an independent product team that has spent years working on calculation engines, electrical systems, and small-business tools. We're not a battery manufacturer, not a solar installer, and not affiliated with any single vendor. That's deliberate — it's the only way the recommendations stay honest.
If you want to suggest improvements, report a bug, or tell us we got something wrong about your rig, we read every message: info@foodtruckbattery.com.
The site is in open beta. The calculator engine is locked and validated against real-truck benchmarks, but we're actively polishing the UI, adding equipment models, and refining the spec output based on operator feedback. Expect occasional updates. If something looks off, please tell us.
