Sunsynk monitoring with PVBiz
PVBiz reads your plant's live power flow, battery, grid and inverter figures from the Sunsynk cloud about every five minutes, adds hourly energy totals, and is the only brand where it can also change inverter settings.
Updated 11 November 2026
What PVBiz reads from Sunsynk
Share the plant with the PVBiz account ([email protected]) on the Sunsynk cloud, or add your own Sunsynk username and password. Available to homeowners today.
| Data | Detail |
|---|---|
| Live power flow | Solar generation, battery power, grid power and home load, read about every five minutes per inverter from separate load, solar, battery and grid readings. |
| Solar strings | Per-string MPPT voltage, current and power for strings 1 to 10, plus lifetime and today's yield. |
| Battery | State of charge, power, voltage, current, temperature, today's charge and discharge, capacity and current limits. |
| Grid and load | Grid frequency and status, today's import and export, per-phase voltage, current and power, essential and non-essential load, and generator power. |
| Inverter | AC and DC temperatures. |
| History and totals | Daily, monthly and yearly energy (solar, load, import, export, charge, discharge) refreshed hourly, backfilled from the year the plant was created. Intraday 15-minute energy is kept too, but only for the last 90 days because that is all Sunsynk retains. |
| Inverter control | Yes. Sunsynk is the only brand where PVBiz can change inverter settings. Settings available are force charge, work mode, energy mode, solar export, grid peak shaving, battery charge current and a six-slot battery timer, with schedules and automations on top. This needs the plant shared with Manager permission or your own Sunsynk login added in PVBiz; a view-only share is monitored but refused control |
How to connect Sunsynk
No hardware to install. PVBiz reads the plant, and changes settings only if you give it permission to.
Share the plant on the Sunsynk cloud
In the Sunsynk app or web portal, open the plant, choose Share and share it with [email protected]. A view-only share is enough for monitoring and alerts. Share with Manager permission instead if you want to change inverter settings from PVBiz.
Add it in PVBiz
Sign in to PVBiz, choose Sunsynk and claim the plant you shared. If the owner email on the plant matches your PVBiz account the claim is approved straight away; otherwise a PVBiz administrator approves it. If you prefer, add your own Sunsynk username and password instead, which PVBiz stores encrypted.
Wait for the first sync, then set your rules
PVBiz pulls your totals and recent intraday history, and the plant then appears with its figures. The default rules cover grid loss, low battery and inverter faults; add your own thresholds and pick the channels.
Alerts that work on Sunsynk
Delivered by push, email and Telegram, with WhatsApp as an optional add-on.
- Grid disconnected and grid restored
- Battery state of charge below a level you set
- Inverter fault, inverter warning and inverter offline
- Communication failure when no data arrives for a period you choose
- AC temperature, essential load and other inverter metrics against your own thresholds
Known limits
- PVBiz reads what the Sunsynk cloud holds. If the inverter's data logger is offline, PVBiz reports the plant offline rather than guessing.
- Intraday history is limited to 90 days by Sunsynk, so finer-grained data older than that cannot be recovered. Daily, monthly and yearly totals go back to the year the plant was created.
- Sunsynk's own daily totals can lag by one to three days, so the most recent days may be corrected after the fact.
- Grid import and export arrive as a single net power figure; today's import and export energy are separate daily counters.
- A view-only share cannot change settings. Testing your own login can take up to 90 seconds, which is the Sunsynk cloud's response time, not PVBiz's.
Connecting Sunsynk is one of the simplest set-ups PVBiz offers: there is nothing to install. You either share the plant with the PVBiz account on the Sunsynk cloud, or you add your own Sunsynk username and password, and PVBiz confirms it can see the plant. If you share, you never hand over your password.
What you get on Sunsynk
Sunsynk exposes one of the fullest sets of readings of any brand PVBiz supports. Load, solar, battery and grid are read separately for each inverter, so the live flow diagram and the alert rules can use per-string solar data, per-phase grid figures, essential and non-essential load, battery temperature and generator power where your system reports them. All the alert rules PVBiz offers can be pointed at Sunsynk metrics.
Live readings are refreshed about every five minutes. Hourly, PVBiz refreshes energy totals for solar, load, grid import, grid export, battery charge and battery discharge. When a plant is first connected, totals are backfilled from the year the plant was created, so analysis and seasonal comparisons have real history from day one.
Control is a Sunsynk-only feature
PVBiz is read-only on every other brand. On Sunsynk it can also write settings, but only with Manager permission on the share or your own login. Force charge, work mode, energy mode, solar export, grid peak shaving, battery charge current and the six-slot battery timer can all be changed from PVBiz, and schedules and automation rules can drive them. If you shared as a view-only visitor, PVBiz says so plainly when you try to change something and leaves the inverter alone.
Honest limits
The 90-day intraday limit is Sunsynk’s, not PVBiz’s: the vendor keeps only the last 90 days of fine-grained data, so anything older cannot be fetched. Daily totals from Sunsynk can be late by a day or two and PVBiz corrects them as the vendor settles its numbers. Everything PVBiz shows is what the Sunsynk cloud knows, so a logger that has lost its connection shows as offline.
