Proper use also includes:
- Carefully studying and obeying the installation and operating instructions
- performing all stipulated inspection and maintenance work
Observe the stipulations of the power supply company concerning energy fed into the
grid and the operation of storage systems.
Increase in stor-
age capacity
The storage capacity of the Fronius Solar Battery can also be increased after purchase
to a maximum capacity of 9.6 kWh of usable energy.
The capacity is increased by adding additional battery modules and this must be carried
out by a qualified electrician.
Capacity can be expanded within 2 years from the date of purchase, but a maximum of
30 months following dispatch from Fronius Austria.
The capacity cannot be increased after this for technical reasons. Observe the stipula-
tions of the distribution network operator concerning energy fed into the grid and the
operation of storage systems.
State of charge
(SOC) accuracy
Adding or replacing a memory module can lead to inaccuracies when calculating the
state of charge (SOC). Straight lines and jumps can occur, in particular immediately after
the upgrade. These only affect the display of the state of charge and do not affect opera-
tion of the device.
