Loads
Pick the equipment you expect to run
Starting values are planning defaults. Use the equipment label or measured draw when you have better numbers.
Up to 30 loads in the shared Power Profile.
Duration
How long does this plan need to cover?
Runtime above remains per day. Duration sets the parked/use window without multiplying the stored daily load values.
Charging / recharging
How do you expect to put energy back in?

Normal language
What will charging look like?
Pick the way you actually travel or use the system. You can leave details uncertain and refine them later.
Solar
What kind of solar do you have?
If wattage is unknown, leave it unknown. The calculator will not invent solar production.
Driving
About how much recharge opportunity do you get?
Use a rough daily estimate. “Not sure” stores 0 hours so driving does not get free credit.
Advanced charging assumption
30 A is the existing planning default. Change it only if you know the actual DC-to-DC / alternator charging current.
Your power plan
Here’s what your setup actually needs.
Your selected loads, trip duration and charging plan have been calculated together by the Heeler Power Engine.
