 | WARNING Since aPower provides backup power storage, ensure that all aPower units, solar inverters, generators, grid power, and aGate breakers are physically disconnected before performing any maintenance on the home power supply system. |
Before arriving on site, conduct a remote investigation using the app. For guidance, refer to the article: FHP Remote Troubleshooting Investigation via Installer App . If you follow the troubleshooting steps and the issue persists, please contact us. You’re also welcome to call us upon arrival if needed.
Resetting FHP:
To reset the FHP, you need to turn off the aGate power switch, wait at least two minutes, then turn it on again.

How do I black start the FHP when the SOC is shown as 0?
Turn off any home devices that might attempt to run during the black start process
Reset all aPower switches
Check if the solar system is operating correctly and generating sufficient power
What if the app notifies me that the “Battery reserve has run out”?
Low battery and black start indicate critically low battery capacity. Before dispatching a technician for the aPower, check the utility website for outage announcements, confirm if the solar system is offline, and verify if there is sufficient sunlight.
- Disconnect the backup and auxiliary power, which will put the system into sleep mode. The system will automatically recover and charge the batteries the next day if sufficient sunlight is available.
- Before initiating the black start, ensure all household loads are turned off, or have the homeowner shut down appliances to allow the FHP to start properly.
- If you're onsite and need to expedite the process, a manual black start option is available as an alternative to waiting for the automatic black start. However, proceed with caution—manual black starts consume reserve capacity. Only attempt this if there is sufficient solar production; otherwise, the system may lock.
Manual Start:
Turn off the aPower switch (extended, flush with case) on the side of all aPower units, wait 60 seconds, then turn on all aPower batteries. The system will start up.

- Ensure that all the household appliances are shut down, to help the system successfully start.
- Check whether the solar system is operating normally and whether there is sufficient sunlight.
What if main page of app shows no connection to solar?
Grid Tied/On Grid Systems:
- Verify that there is sufficient sunlight
- Check that there is voltage on the PV breaker in the aGate or load panel connected to an aPbox.
- Check that the PV inverter is running with no fault codes of its own.
- Please contact Franklin Support if that does not resolve the issue.
Off-Grid Systems:
- Verify that there is sufficient sunlight
- Check that there is voltage on the PV breaker in the aGate or load panel connected to an aPbox.
- Check that the PV inverter is seeing the voltage from the breaker and running normally.
- If a single aPower is at 100% SOC the PV relay will turn off and the system will wait until the highest aPower SoC is below 90%.
- If the photovoltaic power produced is too high, exceeding the battery charging power, the PV relay will turn off.
If all these attempts fail to solve the problem, please contact FranklinWH for support and note what procedures you have already followed. We can then leverage our Technical Service team's knowledge and work with our Research and Development team when needed to resolve issues swiftly together.
What if the Main Page of App shows no Connection to Grid Power Supply?
1. Check the grid for a power outage
2. Check if the wiring is normal
3. Measure and check, using a multimeter, that the grid power voltage is at normal level
4. Check whether the grid relay is reporting open or closed
5. Restart the app and check the network status
6. Reference the FHP Service Manual
7. If all these attempts fail to solve the problem, please contact FranklinWH for support
What if the app prompts “aPower stopped”?
This prompt means that the aPower has stopped working, in which case you need to check the AC wiring for potential open or short circuit. From there, the next step would be to confirm there are no issues with CAN line controlling the battery. Other faults may also lead to aPower shutdown. Please call us while still on site if you require any assistance.
What if the app prompts “FHP system stopped”?
Restart the FHP system after troubleshooting other problems that caused the shutdown. If the app prompts "FHP system stopped" again, please consult the FranklinWH service team for support.
