protection function will be enabled when the photovoltaic output power is greater than
the sum of the absorbable and load power of the FranklinWH system. The photovoltaic
system will automatically be disconnected. When the photovoltaic output power is lower
than the sum of the recharging power and load power of the FranklinWH system, the
photovoltaic system will automatically be reconnected to the FranklinWH system.
Full Charge Protection
When the FranklinWH system is off-grid, the solar system will automatically disconnect as
soon as one aPower battery in series is full (SOC = 100 %). After the FranklinWH system
meets the recovery conditions, the solar system automatically connects to it and outputs
power.
Black Start
When solar power is insufficient, the grid power is unavailable, and the aPower battery
available power is exhausted, the Smart Circuits will be automatically disconnected and
the system enters sleep mode, waiting for a black start attempt.
Automatic Black Startup
The system will automatically start at specified times every day. If the solar energy
supply is sufficient, the electricity generated by the photovoltaic system will charge
the aPower battery. If the solar power is insufficient, the system will re-enter sleep
mode, waiting for the next automatic startup.
Manual Black Startup
When the solar energy supply is sufficient, you can manually start the system instead
of waiting for the automatic black startup. Manually turn off the round button switch
on the side of the aPower, turn it back on 20 seconds later, and the system will be
started.
• Repeated startup attempts may result in system lockdown. In order to
increase the success rate of black startup, please make sure that the
heavy electrical loads have been turned off, until the aPower is charged
to 20 % SOC or higher.
• If the grid is restored when the system is in sleep mode, the system will
start immediately.
