Gateway Overload Issues
In periods of low solar generation (such as winter or extended cloudy weather), GivEnergy Gateways may experience higher electrical demand from the grid. This can occasionally lead to Gateway overload issues, particularly when household consumption is high.
This article explains why Gateway overloads can occur, how to identify them, and what steps you can take to safely recover the system.
Why Gateway overloads are more common at certain times of year
When solar generation is reduced, your system relies more heavily on the grid to supply power. If multiple high-demand appliances are running at the same time, the electrical load passing through the Gateway can increase significantly.
In these situations, the Gateway may temporarily struggle to manage the demand, especially if grid voltage is lower than normal.
What to check if you suspect a Gateway overload
1. Check total power (PAC)
If the total power passing through the Gateway (PAC) exceeds 18 kW, the system may experience instability or protective shutdown.
High PAC values usually occur when multiple large loads (for example ovens, heat pumps, EV chargers, or immersion heaters) are running simultaneously.
2. Check grid voltage (VAC)
If grid voltage drops below approximately 230 V while power demand is high, the Gateway has to work harder to deliver the same amount of energy.
A combination of high load and lower voltage can increase the likelihood of an overload condition.
How to recover from a Gateway overload
In most cases, a full system reboot will clear the issue.
Recommended reboot method
- Open the Gateway Remote Control page.
- Select Restart Hardware.
- Click 'Restart All' to apply the command.
- Allow several minutes for the Gateway and connected devices to fully reboot.
Once restarted, the Gateway should resume normal operation.
Reducing the chance of repeat issues
If overloads occur frequently, an installer may recommend:
- Ensuring the AIO import limit is set to 80 A or lower.
- Reviewing how high-power appliances are scheduled or grouped.
- Checking overall system design against household demand.
These adjustments help prevent excessive demand from passing through the Gateway at once.
When to contact your installer or GivEnergy Support
You should seek further assistance if:
- The Gateway repeatedly overloads despite reboots.
- PAC frequently exceeds 18 kW during normal household use.
- The system does not recover after a restart.
Providing screenshots of PAC, grid voltage (VAC), and your Gateway configuration
will help diagnose the issue more quickly.
