Energy
Watts × daily run time = watt-hours. This determines how much battery capacity you need.
TORVEN POWER PLANNER
Choose the appliances and systems you want to keep running. We’ll estimate the battery storage, inverter output, and solar capacity that fit your goals with confidence.
Step 1 of 3
Choose the closest starting point. You can change every load in the next step.
Step 2 of 3
Select your loads, then adjust the quantities, wattage, and daily run time below.
Your load list
Select a load above or add your own. Wattage estimates remain fully editable.
Step 3 of 3
Set the backup window and local solar conditions. Your plan updates immediately.
Battery estimate: 90% usable capacity, 92% conversion efficiency, and 10% reserve.
Solar estimate: 80% overall production factor. Inverter output includes 25% continuous headroom plus the largest selected motor-start surge.
Plan with confidence
The planner separates capacity from output because a battery can store enough energy and still be unable to start a high-demand appliance.
Watts × daily run time = watt-hours. This determines how much battery capacity you need.
Running watts and the largest motor start determine the inverter's continuous and surge ratings.
Daily energy ÷ peak sun hours, adjusted for system losses, creates the solar array target.
Planning estimate only. Actual wattage, duty cycle, motor surge, temperature, battery limits, wiring, code requirements, shading, and weather vary. Verify equipment nameplates and product specifications before purchase. Hardwired 120/240V systems and transfer equipment require qualified design and installation. Do not use this estimate as the sole basis for life-safety or medical equipment.
