STEP 01 / YOUR USAGE
What do you want to power?
Select real-life examples or add your own equipment. Every figure can be adjusted.
Add a custom appliance
Use the input power shown on your device's label or datasheet.
YOUR APPLIANCE LIST
Fine-tune your daily usage
Hours represent actual time drawing the stated running wattage, not standby time.
Add appliances above to build your personalised power plan.
Tip: A 45W fridge compressor running 8 hours in 24 uses 360Wh/day, not 45W × 24 hours. Change running hours for your weather, thermostat and usage.
STEP 02 / SYSTEM DESIGN
Tailor the system to your trip
These settings affect the size of the battery, inverter and solar array.
Inverter idle consumption only applies for the selected hours. Solar output is an indicative daily energy balance, not a winter guarantee. Battery minimum state of charge: 20% for lithium, 50% for lead-acid. Check individual manufacturer specifications.
