How SUNA gets the values

SUNA Homeat home on your network, live

OpenInverterGateway stable

The Growatt USB stick running the free OpenInverterGateway firmware and an MQTT broker on your network. Something for tinkerers.

  • PV power
  • each string
  • battery and charge level
  • grid import and export
  • home consumption
  • temperatures

New values about every 10 seconds, even without internet.

RS485 gateway Beta

An RS485 gateway for about 30 to 40 € on the RS485 port of the inverter, connected to the router by cable. Plus a small computer that runs SUNA.

  • PV power
  • each string
  • battery and charge level
  • grid import and export
  • home consumption
  • temperatures

New values every 10 seconds, even without internet.

Growatt cloud Beta

An API token that you create yourself in the ShinePhone app. No hardware.

  • PV power
  • battery and charge level
  • grid import and export
  • home consumption

New values about every 5 minutes.

From these values SUNA calculates daily totals, history and statistics.

Good to know

  • Locally the easiest way is an RS485 gateway. If you like tinkering, use OpenInverterGateway, it runs stable.
  • SUNA calculates home consumption without the inverter losses. It is therefore often lower than in the Growatt app, but more accurate.
  • You create the API token for SUNA Online yourself in the ShinePhone app, nothing to apply for.
Growatt

MIN and TL-XH

Growatt string inverters for house and garage. SUNA shows them via the Growatt cloud.

Which models belong to it

  • MIN 2500 to 6000TL‑X and X2, single-phase, 2.5 to 6 kW
  • MIN 7000 to 10000TL‑X and X2, 7 to 10 kW
  • MIN TL‑XH and XH2 with a port for a battery
