Growatt monitoring with PVBiz

Growatt connects through an API token rather than a username and password, and that shapes the whole integration. You choose the server region your account lives on, either Global, United States, China or Australia, paste the token, and PVBiz reads through Growatt’s open API. Your password is never used. The token is stored encrypted and is write-only in the app.

Ten-minute refresh

Growatt is the slowest-refreshing integration PVBiz runs: live readings update every 10 minutes instead of every 5. That is how Growatt is configured in PVBiz. Energy totals still refresh hourly. If a fast reaction to a grid or battery event matters to you, bear in mind that a Growatt alert can arrive up to that much later than on other brands.

What PVBiz reads

PVBiz reads the plant’s main inverter. From it come solar power, battery power, state of charge, voltage and temperature, load output power, grid frequency, status and power, today’s import and export, and inverter and DC temperature. There are no per-string MPPT readings and no per-phase data.

History

Daily totals come from Growatt’s own counters for today. Monthly and yearly figures are sums of the daily records PVBiz has stored, and lifetime totals are not fetched. PVBiz does not confirm a first-connect backfill for Growatt, and Growatt itself retains only around three months of history, so plan on history building from the day you connect.

Alerts and limits

The standard alerts run on Growatt: grid loss, low battery, inverter fault and offline, and loss of communication, with custom thresholds on the metrics above, though not on generator power, the essential load split or grid voltage. Growatt does not give PVBiz plant status, rated power or a time zone, so these are inferred. There is no control: Sunsynk is the only brand where PVBiz changes settings.
