Energy ToolsetHow Battery Backup Use Case Classifier works
Press Load model once: your browser downloads Universal Sentence Encoder (MediaPipe) (13 MB) from this site and keeps it in its cache. Then add your text and press Classify locally. The model runs on this device, so nothing you enter is sent to a server. Until the model is loaded, or if your device cannot run it, the tool falls back to a simple keyword check and labels the result as the fallback.
Universal Sentence Encoder (MediaPipe) turns text into a list of numbers that captures its meaning, so two sentences about the same thing end up close together even when they share no words. Each label below comes with a handful of example phrases. The tool compares your text with every example and picks the label whose closest example is nearest in meaning.
Scores are the cosine similarity between your text and that closest example, rescaled to 0-100: this model rarely scores two English sentences below 0.6 even when they are unrelated, so 0.6 maps to 0 and an exact match to 100. When the top two labels are within 3 points the result says it is a close call, because the model is effectively unsure.
Labels and example phrases
- Medical device backup - Size for the devices' wattage and run time; ask your utility about medical baseline programs and keep a separate plan. Examples: "need to keep my oxygen concentrator running during outages", "CPAP machine has to work when the power goes out", "home dialysis equipment needs reliable power".
- Outage backup for essentials - Pick the circuits you must keep (fridge, internet, sump, furnace fan) and size for the longest outage you expect. Examples: "keep the fridge, internet and lights on during blackouts", "sump pump must run when storms knock the power out", "we lose power a few times every winter".
- Bill savings with time-of-use rates - Compare peak and off-peak prices; savings depend on the spread and battery cycling. Examples: "charge the battery off-peak and use it from 4 to 9pm", "avoid peak electricity prices in the evening", "our utility moved us to a time-of-use plan".
- Storing solar for later - Check your net metering or export rate; batteries pay off most when exports earn little. Examples: "store extra solar during the day for the evening", "net metering ended so exports are worth very little", "use more of our own solar power".
- Off-grid or remote power - Size for days of autonomy and add a generator or more panels for cloudy stretches. Examples: "cabin with no grid connection", "off grid tiny house with solar panels", "power for a remote workshop far from the lines".
