Solar LIVE ON-CHAIN Base x402 Continuous load is the sum of the running watts of all appliances marked as simultaneous. 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.

▸ GET /off-grid-weather-alarmN/A
Uses the nearest current DWD MOSMIX_L station forecast, or a station explicitly supplied by the caller. Global irradiance drives a transparent PV estimate and forecast wind speed drives a stated generic turbine curve; neither replaces a site-specific yield model. A constant hourly load and optional battery are simulated over 12 to 120 hours. The result is an installation-risk signal, not an official weather warning, emergency alert or guarantee of supply. $0.005 · 99 ms · Base ▸ GET /battery-cycleN/A
Integrates the supplied current over time by the trapezoidal rule, so the result is only as good as the sampling interval; gaps longer than the stated max_gap_seconds are excluded and reported. Sign convention: positive current is charging, negative is discharging. Internal resistance is estimated from the largest current step in the series and is a rough figure, not a measurement under defined conditions. $0.004 · 91 ms · Base ▸ GET /building-heat-demandN/A
Computes a transparent planning estimate for space-heating demand. The method is not DIN, VDI, GEG or PHPP and must not be used as regulatory proof. It combines transmission heat loss from each envelope component, ventilation heat loss from heated volume and air changes, monthly heating degree days from the nearest DWD 1991-2020 temperature-normal station, stated internal gains and optional domestic hot water. $0.004 · 11 ms · Base ▸ GET /autonomy-forecastN/A
Daily energy balance and straight run-down from the figures supplied. Solar input is caller data in watt-hours per day; nothing is fetched and no weather is assumed. Time to empty means time to the reserve floor, not to zero. Idle draw and conversion efficiency apply to AC loads only. Ageing, temperature and Peukert behaviour are not modelled, which matters for lead acid far more than for LiFePO4. $0.003 · 11 ms · Base ▸ GET /low-wattage-cookingN/A
Uses rated electrical power, food mass, start and target temperature, specific heat and an explicit efficiency range supplied by the caller. Optional vessel heat, evaporation and a caller-defined hold phase can be included. It contains no recipes, recipe text, food-specific cooking claims or hidden food database; the output separates the thermodynamic lower bound from the practical range and is not a food-safety clearance. $0.003 · 11 ms · Base ▸ GET /victron-log-parseN/A
Reads the key-tab-value lines of the VE.Direct text protocol, applies the unit scaling that belongs to each key, and decodes the charger state, tracker state and error number into plain text. Multiple blocks in one dump are returned as separate records in order. Keys that are not in the field table are preserved verbatim under unknown_keys rather than guessed at. The checksum line is not verified, since a text export usually no longer carries the original byte framing. $0.003 · 46 ms · Base ▸ GET /inverter-load-checkx402 ! Unstable
Continuous load is the sum of the running watts of all appliances marked as simultaneous. 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. $0.002 · 27 ms · Base ▸ GET /inverter-lossesx402 ! Unstable
Cable loss uses the DC resistance of the two-way run at twenty degrees Celsius; warm cable in a hot compartment carries roughly four percent more resistance per ten kelvin, which is not applied. Inverter loss follows a three-part model of idle draw, a proportional share and a quadratic share, fitted so that the stated peak efficiency is met near half of the rated power. $0.002 · 12 ms · Base ▸ GET /shadow-simulatorx402 ! Unstable
Pure astronomy and geometry on level ground: sun position by the NOAA method, shadow length as object height divided by the tangent of the sun elevation. Refraction is only applied to sunrise and sunset. Terrain slope, surrounding buildings, vegetation and diffuse light are not modelled, so a point outside the shadow can still be shaded in reality. Times are UTC. $0.002 · — · Base ▸ GET /clear-sky-yieldN/A
This is an astronomical and geometric calculation, not a forecast. It assumes a cloudless sky and states the models used; real yield is lower whenever there is cloud, haze, snow, soiling or high cell temperature. The system_derate factor covers cabling, controller and temperature losses as one flat number and defaults to 0.8. Shading is not modelled here. Times are UTC. Use the figure as an upper bound for sizing, not as an expected daily production. $0.003 · — · Base ▸ GET /tilt-optimiserN/A
Evaluates clear-sky irradiance in the module plane for tilt angles from zero to ninety degrees on the fifteenth of each month and sums the days. Because it assumes a cloudless sky, the optimum leans slightly steeper than a real-weather optimum, where diffuse light from an overcast sky rewards flatter angles; in summer the difference is small, in winter months it reaches ten to fifteen degrees, so treat the winter figures as an upper bound. $0.003 · — · Base Same category, ranked by Trust score — switch to a more reliable or cheaper source.
