POWER PLANNING TOOLKIT

Load → Capacity → Runtime → Recharge

Use the tools in order: identify essential loads, check output and stored energy, estimate runtime, then plan how the system can recharge. Every result is a planning estimate.

01 · LOAD

AVAILABLE TOOL

Essential Load Planner

List the devices you may need during an outage and see how their running load, possible startup demand, hours, and priority affect the plan.

Planning Estimate: Startup watts are shown as a possible peak. The tool does not assume every device starts at the same moment.

Essential-load summary: add devices to build your plan.

Medical equipment requires the equipment provider's compatibility and backup-power guidance. This planning estimate is not a medical-device compatibility guarantee.

02 · CAPACITY

AVAILABLE TOOL

Refrigerator Outage Estimator

Use the existing refrigerator calculator to estimate capacity, continuous output, startup surge, and outage energy from your appliance inputs.

Planning assumptions are shown on the calculator: 85% efficiency, 20% sizing margin, and 3× startup surge when appliance-specific data is unavailable. Watt values are rounded up to the next 50 W step.

03 · RUNTIME

AVAILABLE TOOL

Appliance Runtime Calculator

Estimate how long a load may run from battery energy, reserve settings, efficiency, and appliance demand.

Battery capacity (Wh) Usable capacity or reserve (%)Reserve held back from the nameplate capacity. Appliance load (W) Efficiency assumption (%)SealedPick planning assumption; adjust only when you have better data. Optional sizing margin (%)

Planning Estimate

—Estimated runtime

—Estimated energy used

—Remaining reserve

Actual power draw, conversion losses, low-battery protection, and device operating cycles can change the result. This is not a guaranteed runtime.

04 · RECHARGE

AVAILABLE TOOL

Solar Recharge Calculator

Estimate energy still needed and charging time while accounting for panel output, sunlight, system loss, and the station's solar-input limit.

Battery capacity (Wh) Current state of charge (%) Target state of charge (%) Panel rated output (W) Effective sunlight hours Station solar-input limit (W) Estimated system loss (%)

Planning Estimate

—Energy still needed

—Estimated charging time

—Panel vs input limit

The panel's rated output is not a guaranteed continuous input. Sunlight conditions, system loss, input limits, and charging tapering near high state of charge affect actual results.
