The surge check adds the largest single starting surge on top of the continuous load, which is the case that trips an inverter; simultaneous starts of two motors are reported separately as a second figure. Starting factors and power factors are design rules of thumb per appliance class and are stated in the response, they are not device data.","url":"https://solar.halowerk.com/inverter-load-check","method":"POST","headers":{},"bodySchema":{"type":"object","properties":{"loads":{"type":"array","items":{"type":"object","required":["name","watts"],"properties":{"name":{"type":"string"},"type":{"type":"string","description":"Appliance class: resistive, electronics, led, motor, pump, compressor, induction."},"watts":{"type":"number","maximum":50000,"minimum":0.1},"quantity":{"type":"integer","default":1,"maximum":200,"minimum":1},"power_factor":{"type":"number","maximum":1,"minimum":0.3},"simultaneous":{"type":"boolean","default":true,"description":"False if the appliance never runs together with the others."},"surge_factor":{"type":"number","maximum":12,"minimum":1}},"additionalProperties":false},"maxItems":60,"minItems":1},"inverter":{"type":"object","required":["continuous_w"],"properties":{"idle_w":{"type":"number","default":15,"maximum":500,"minimum":0},"surge_w":{"type":"number","maximum":400000,"minimum":50,"description":"Peak rating.
