Overview
FranklinWH Black Start attempts to restart a system at specified times each day by activating the photovoltaic (PV) system. With the standard black start, when solar energy supply is sufficient, the electricity generated by the photovoltaic system will be used to:
- Restart the Franklin Home Power System.
- Power household loads.
- Charge the aPower batteries.
However, if higher-power appliances are connected to the backup load-side and consume significant power, black start may fail.
Optional Main Load Relay
With the optional Main Load Relay installed:
- The aGate will automatically disconnect load-side electrical circuits, ensuring PV production initially charges the aPower batteries.
- This significantly improves black start success rates.
- When the batteries reach a homeowner-set level of charge, the aGate will reconnect the Main Load Relay, returning power to home loads.
Without this module, manual disconnection of electrical appliances is required.
Benefits
The Main Load Relay ensures:
- A more reliable black start process.
- Restored power supply to the home as soon as there is sufficient solar production, even during extended power outages.
