With the market launch of its new Fronius Energy Package, Fronius is introducing an
inverter that can be used to store energy. One of the key components is the Fronius
Solar Battery, which contains a lithium-ion rechargeable cell. The Fronius Solar Battery
supplements the Fronius hybrid inverter by adding storage functionality. This means that
the solar energy from the solar modules can be stored for later use.
The storage system is only suitable for operation in conjunction with Fronius hybrid
inverters.
Thanks to its design and operating principle, the storage system is extremely safe both
to install and to operate. A high-performance lithium-ion phosphate battery is used (LiFe-
PO4), which is based on the latest technology and complies with the highest safety
standards.
When used in conjunction with the Fronius inverter, operation of the storage system is
fully automatic.
If proper charging of the batteries in the Fronius Energy Package cannot be guaranteed
for an extended period of time (over several weeks or months) for any reason, we
strongly recommend that the following steps are undertaken to prevent the deep dis-
charge of the battery modules:
