Huawei FusionSolar monitoring with PVBiz
PVBiz reads inverter, battery and grid-meter figures from FusionSolar about every five minutes, refreshes energy totals hourly and pulls in FusionSolar alarms, read-only, on the PVBiz Installer Platform.

What PVBiz reads from Huawei FusionSolar
Add a FusionSolar account username and password under Integrations on the PVBiz Installer Platform. Available on the PVBiz Installer Platform today.
| Data | Detail |
|---|---|
| Inverter live data | Output power, phase voltage and current, today's and lifetime energy, frequency and inverter temperature. |
| Solar strings | Up to 20 strings are combined into 10 channels (voltage averaged, current and power summed). |
| Battery | On battery inverters, power, state of charge, voltage, temperature, current, and charge and discharge energy. |
| Grid meter | Grid power, import and export where a meter is installed. |
| FusionSolar alarms | Current alarms matched to the inverter, ranked critical, warning or info, and closed automatically when FusionSolar clears them. |
| History and totals | Solar, load, import, export, charge and discharge, refreshed hourly and backfilled to the plant's creation date. |
| Inverter control | No, monitoring only |
How to connect Huawei FusionSolar
No hardware to install. PVBiz only reads the plant; it never changes a setting.
Prepare a FusionSolar account
Use a FusionSolar account that can see the plants you want to monitor. For larger fleets the app suggests adding more than one account, because Huawei limits how fast its service can be queried. The app's connect screen shows what is needed.
Add it on the Installer Platform
In the PVBiz Installer Platform choose Integrations, add Huawei FusionSolar and enter the username and password. They are stored encrypted and never shown again. PVBiz lists the plants the account can reach so you pick which to sync.
Let the first sync run
PVBiz discovers the plants and inverters, then backfills daily and monthly totals back to the earliest plant creation date. Switch on rules and alerts for the fleet.
Alerts that work on Huawei FusionSolar
Delivered to your team by email, Slack, Microsoft Teams, Discord or webhook.
- Inverter offline and plant offline
- Communication failure when no data arrives
- FusionSolar alarms raised as PVBiz events with their severity
- Thresholds on the inverter, battery and grid metrics PVBiz reads
Known limits
- Huawei rate-limits its service heavily. PVBiz waits and retries when it is throttled, and a large fleet is best spread across several FusionSolar accounts.
- Some devices that fail repeatedly are skipped for 24 hours before PVBiz tries them again.
- DC temperature is not read, and the data has no collection timestamp from Huawei.
- PVBiz is read-only on FusionSolar.
- Available on the PVBiz Installer Platform today. Homeowner subscriptions do not include FusionSolar at the moment.
Huawei FusionSolar is one of the heavier-weight integrations because Huawei throttles its service aggressively. PVBiz is built for it, but the practical result is that fleet operators get the best results by spreading plants across more than one FusionSolar account, and the connect screen in the Installer Platform says so. Huawei FusionSolar is available on the PVBiz Installer Platform today, which is where installers and O&M teams monitor fleets across brands. Homeowner subscriptions do not currently include it.
Connecting
You add a FusionSolar account username and password under Integrations. PVBiz stores them encrypted, lists every plant that account can reach, and lets you choose which to sync. Read-only access is all that is used; nothing is written back to your inverters.
What PVBiz reads
String inverters and battery inverters are both covered, and a grid meter is read where fitted. From the inverter PVBiz takes output power, per-phase voltage and current, today’s and lifetime energy, frequency and temperature. Up to 20 strings are combined into 10 channels. Battery inverters also give battery power, state of charge, voltage, temperature, current and charge and discharge energy. Readings poll about every five minutes and totals refresh hourly. Totals are backfilled to the earliest plant creation date.
Alarms
Unlike most brands, FusionSolar’s own alarms are brought in whenever the portal session is available. Each is matched to its inverter, tagged critical, warning or info, and closed automatically when FusionSolar reports it cleared. On top of that, PVBiz’s own rules give inverter offline, plant offline, communication failure and custom thresholds on the metrics above.
Known limits
Because Huawei limits request rates, PVBiz paces its calls, waits when throttled and skips a device for 24 hours if it keeps failing. DC temperature is not read and Huawei provides no collection timestamp with the readings. There is no control on FusionSolar; Sunsynk is the only brand where PVBiz can change settings.
