What are you planning?
Choose the closest application. This helps the planner select a sensible voltage direction and identify application-specific cautions.
Build your battery system plan
Enter the equipment you need to power and how long it runs. The planner calculates an educational battery bank, voltage, inverter, solar array, charger, component checklist, and equipment budget without collecting your contact information.
Frequently asked questions
What does the Battery System Planner calculate?
It estimates daily load energy, nominal LiFePO4 storage, system-voltage direction, inverter continuous and surge power, solar-array size, controller current, charger current, and a broad equipment budget.
Does HighLiFePO4 collect my contact information?
No. This planner does not ask for a name, email address, phone number, location, or quote request. Calculations run in your browser during the current visit.
Are home backup and off-grid systems safety-sensitive?
Yes. The result is an educational planning estimate, not an electrical design. Final equipment, wiring, overcurrent protection, permits, and code compliance should be verified for critical or code-sensitive systems.
Why can the result differ from a retailer's battery calculator?
Calculators may use different load hours, reserves, conversion losses, usable battery depth, weather assumptions, and solar derating. This planner shows its assumptions so you can review and change the important inputs.
