Troubleshoot a FranklinWH aPower system not restarting after a power outage. Check battery status, connections, and safety measures. Expert guide.
The FranklinWH aPower battery typically has a lifespan of 10 years or more, depending on usage patterns and environmental conditions. Refer to the manufacturer's warranty for specific details.
The State of Health (SOH) of the battery can usually be monitored through the FranklinWH monitoring app. The app provides insights into the battery's remaining capacity and overall health. If the app doesn't provide this information directly, contact FranklinWH support.
The recommended operating temperature range for the FranklinWH aPower battery is typically between 15°C and 30°C (59°F and 86°F). Extreme temperatures can negatively impact battery performance and lifespan. Ensure adequate ventilation around the system.

Battery systems contain high DC voltage that can be lethal. Always disconnect the DC disconnect switch before performing any maintenance or troubleshooting. Never work on live circuits. Wear appropriate personal protective equipment (PPE), including insulated gloves and safety glasses. Ensure proper ventilation to prevent the accumulation of explosive gases. This work should only be performed by a qualified electrician familiar with NEC Article 706 and 690 requirements.
The aPower system relies on a Battery Management System (BMS) to monitor cell voltage, current, and temperature. During a power outage, the system switches to battery backup mode. If the BMS detects a critical fault (e.g., low voltage, over-current, or over-temperature), it will shut down the system to protect the battery. Communication between the battery modules, inverter, and grid is crucial for proper operation. The system requires sufficient DC bus voltage to initiate the AC output.
Try performing a system reset by simultaneously pressing and holding the reset button (if available) on the inverter and battery module for 10 seconds. This may clear any temporary glitches and restore system operation. Refer to the manufacturer's documentation for the correct reset procedure.
The FranklinWH aPower system fails to resume operation following a utility power outage. The system remains offline, providing no backup power to the connected loads. The monitoring app indicates a system-down status or displays no data.
