Sol-Ark monitoring with PVBiz

Sol-Ark is one of the fullest integrations PVBiz offers on the read side, and one of the clearest on the limits: it is monitoring only. You add your Sol-Ark Cloud (MySolArk) username and password, PVBiz fetches your plants, and you choose which to sync. There is no share step on Sol-Ark. The login is stored encrypted and is write-only in the app.

What PVBiz reads

For each plant’s master inverter PVBiz reads solar power with today and lifetime yield, strings 1 to 10 with voltage, current and power, and load power including total, essential, non-essential and per-phase figures. The battery is covered in depth: power, state of charge, voltage, current, temperature, capacity, current limits and today’s charge and discharge. On the grid side PVBiz reads frequency, status, import, export, total and per-phase values, plus generator power and AC and DC temperature. Readings poll about every five minutes and totals refresh hourly.

How totals work

Monthly and yearly totals are Sol-Ark’s own figures, used as Sol-Ark reports them rather than summed up from days. That keeps PVBiz in step with the numbers in the Sol-Ark app. Normal syncs refresh the last 14 days; on first connect PVBiz backfills from the month the plant was created, with a floor of 2020.

Resilience

If one of Sol-Ark’s data calls fails during a sync, PVBiz keeps the rest and flags the gap instead of discarding the whole reading. After a rejected login it backs off rather than repeating the attempt.

Alerts and control

All the standard alerts run on Sol-Ark, including thresholds on per-string solar, generator and battery metrics. Sol-Ark’s own alarm list is not imported. There is no control on Sol-Ark: PVBiz is monitoring only, and Sunsynk is the only brand where it can change settings.
