API field

Auxiliaries: night consumption

Power the system consumes while the sun is down

Unit W

What it is

The power the system draws while the sun stays below the horizon for the whole timestep: control, communication and heating that stay on at night. On a daylight timestep it is not drawn: below the power threshold only the proportional draw applies, and nothing is drawn while the inverters are off. The field is in watts; the API takes kilowatts.

Typical values and how to get it

From the system's auxiliary load list, the loads that stay on at night. If not given: 0 kW: no auxiliary load at night.
