If you have a Generac PWRcell solar system, you may have seen an error message on your inverter screen that says “Island overload” or “Error code 700f”.
This error means that your solar system is producing more power than your home can consume, and the excess power cannot be sent back to the grid or stored in the battery.
In this blog post, we will explain what causes this error, how it affects your solar system, and how to fix it.
What Causes the Generac Inverter Error 700f?
The generac inverter error 700f is caused by a mismatch between the power output of your solar system and the power demand of your home. This can happen due to various factors, such as:
- High solar production during peak hours
- Low power consumption by your home appliances
- Grid outage or instability
- Battery malfunction or disconnection
- Improper installation or configuration of your solar system
When the error occurs, your solar system detects an islanding condition, which means that it is disconnected from the grid and running on solar and battery power only.
However, since your solar system is producing more power than your home can use, and the battery is either full or not available, the excess power has nowhere to go.
This creates an overload situation, which can damage your inverter and other components of your solar system.

How Does the Generac Inverter Error 700f Affect Your Solar System?
The generac inverter error 700f affects your solar system in different ways, depending on the mode of operation and the status of the grid. Here are some scenarios and their outcomes:
Grid-tied mode
In this mode, your solar system is connected to the grid and sells excess solar power to the utility.
If the error occurs in this mode, your solar system will try to reconnect to the grid and resume normal operation.
However, if the grid is unavailable or unstable, your solar system will shut down completely, and you will lose power to your home.
Islanding mode
In this mode, your solar system is disconnected from the grid and runs on solar and battery power only.
If the error occurs in this mode, your solar system will try to reduce the power output by turning off some of the solar panels or limiting the inverter output.
However, if the power mismatch is too large, your solar system will shut down completely, and you will lose power to your home.
Backup mode
In this mode, your solar system is connected to the grid, but uses the battery power as a backup in case of a grid outage.
If the error occurs in this mode, your solar system will behave differently depending on the status of the grid.
If the grid is on, your solar system will try to reconnect to the grid and resume normal operation.
If the grid is off, your solar system will try to reduce the power output by turning off some of the solar panels or limiting the inverter output.
However, if the power mismatch is too large, your solar system will shut down completely, and you will lose power to your home.

How to Fix the Generac Inverter Error 700f?
The generac inverter error 700f can be fixed by adjusting the power output of your solar system or the power demand of your home.
However, this is not a simple DIY task, as it involves working with high-voltage equipment and accessing the roof.
Therefore, it is recommended to contact a qualified service technician or your solar installer to perform the repair.
Depending on the warranty and the contract, you may be eligible for a free or discounted service.
To fix the generac inverter error 700f, the service technician will need to do the following steps:
- Disable the inverter and turn off all photovoltaic breakers
- Check the power output of the solar panels and the power demand of the home appliances using a power meter or a clamp meter
- Adjust the power output of the solar system by adding or removing solar panels, changing the tilt angle or orientation of the panels, or installing a power optimizer or a microinverter
- Adjust the power demand of the home by turning off or unplugging some of the appliances, using energy-efficient devices, or installing a smart thermostat or a load controller
- Enable the inverter and turn on all photovoltaic breakers
- Verify that the solar system is working properly and the error is cleared
