New Features and Enhancements
| Product/Feature | Feature Description |
|---|---|
| SolarEdge Home Hub Inverter – Three Phase + Backup Interface | Backup operation is now supported with the SolarEdge Home Backup Interface and a single Home Hub - Three Phase backup inverter. Support includes backup transition time, imbalance operation during backup, backup recovery after the battery is depleted, and backup operation after a single-phase outage. |
| SolarEdge Home Hub Inverter – Three Phase |
The following backup push notifications are now supported via mySolarEdge:
|
| SolarEdge Home Hub Inverter – Three Phase | All battery alerts and protection modes are now available via battery LEDs. Learn more in the SolarEdge Home Battery 48V Installation Guide. |
| SolarEdge Home Hub Inverter – Three Phase | The SolarEdge Home Hub Inverter – Three Phase now supports AC prevention mode, so when the battery is below its min. SoC, the inverter stops AC production and starts charging the battery from PV until it’s reached a safe charge level. |
| SolarEdge Home Hub Inverter – Three Phase | The SolarEdge Home Hub Inverter – Three Phase is now able to start (wakeup) directly from PV after it reaches “AC prevention” mode and has entered Sleep mode. |
| SolarEdge Home Hub Inverter – Three Phase | The Self-test procedure takes into consideration any charge/discharge power limits that derive from the battery configuration and status (e.g. low/high SOC, thermal derating, etc.) |
| Excess Solar with Zero Export | To comply with import/export regulations, zero power export to the grid is supported even if there is excess PV available over the maximum battery charge rate. |
Known Issues and Limitations
| Issue Summary |
|---|
| During backup, LED lights may flicker when an engine-based load is operated. This is a known issue and doesn’t cause any damage to home loads during Backup operations. |
| EV Chargers may not start during the backup transition and may cause the backup system to trip (shut down). This is a known issue and doesn’t cause any damage to home loads. If this happens, you should turn off the EV Charger and then switch ON the inverter again. |
|
In some cases, after adding the SolarEdge Home Backup interface via the SetApp Device Manager, two types of errors may occur: "Adding failed" or “BUI comm error”. Workaround: |
| A notification is sent to the mySolaredge app that the grid is either up or down while in Backup mode. This is a known issue and doesn’t impact the normal operation of the system during backup. |
|
When the system has been operating in Backup mode for a long period of time, the battery may stop functioning a few percentage points above its minimum capacity. This results in the system Backup operation lasting a few minutes less than expected. |
|
During commissioning, the following attribute may appear in the SetApp status screen: SetApp -> Commissioning -> Status screen > “Line Imbalance window” attribute. This attribute has no significance and should be ignored. |
| If there are several battery modules (= one battery pack) on site connected to the same inverter, monitoring alerts will only show the alerts specific to the battery pack and not for each battery module. This has no impact on system performance. |
| Monitoring dashboard charts may show inaccurate consumption data in the event of a meter communications error. This is only a chart display issue and can be ignored as the system continues to work normally. |
| Backup interface alerts may temporarily fail to appear in the Monitoring Platform dashboard. This has no impact on system performance and can be ignored. |
|
Setting the Backup Reserve parameter to 100% upon battery selection may cause this parameter to change sporadically. Until this issue is resolved, setting Backup Reserve to 100% should be avoided. |
|
In SetApp, if the energy meter configuration shows Import as Export and vice versa, then this is because there is an incorrect initial value for the current transformer’s meter direction. Please contact SolarEdge support to resolve this issue. |
| When upgrading a battery in sites with five battery modules, in some cases one module will appear with firmware version 0.0.0. This error has no impact on battery functionality and will be resolved in the next BMS upgrade. |
| Transitions with Imbalance loads over the different phases may take up to 5-6 seconds. |
| In very rare cases, the transition to Off-grid mode may take up to 18 seconds. After switching to Backup mode, the system will continue to work normally. |
| During the transition to Backup mode, if the battery is in 100% SoC the transition may take between 3-10 seconds. |
| Occasionally, “Site Production” in mySolarEdge may appear as “NA”. This is only a display issue and can be ignored. System production continues as normal. |
