Home Power Automation

What GridPassport can do with a matched APsystems connection

Settings vary by family. GridPassport uses only those exposed by the exact connection confirmed for the home.

01

Make decisions from the whole home

Use live inverter data together with solar forecasts, prices, household demand and the needs of other devices.

02

Use the controls available on your model

Depending on the listed family, GridPassport can adjust the inverter power limit.

03

Keep reserve and device limits

The inverter keeps its own safety logic while GridPassport works only within the settings the confirmed connection allows.

04

Make the devices work together

Time battery decisions alongside heating, cooling and car charging instead of leaving each device on a separate schedule.

Practical setup
