Equalisation charge
Equalisation charge is a charge process in the constant voltage phase. Equalisation charges charge
different series-connected battery cells to a uniform state of charge of 95% … 100%. Without regular
equalisation charging, the states of charge of the individual cells slowly drift apart, which can lead to
premature battery system failure.
Extension cluster
An extension cluster is a cluster within the Multicluster system which is subordinate to the main cluster.
The master of the extension cluster obeys the instructions issued by the master of the main cluster. The
master of the extension cluster sends the operating data of its cluster to the master of the main cluster.
If the master of an extension cluster stops, only this cluster stops working. In this case, the Multicluster
system continues to operate with reduced power.
Fast charge
Fast charge is a charging process in the constant voltage phase. Fast charging charges the battery as
quickly and efficiently as possible to a state of charge of approx. 85% … 90%.
Firmware
Firmware is software embedded in electronic devices. Firmware is stored in a non-volatile, electronic
memory module.
Float charge
In a float charge, the off-grid inverter attempts to maintain the battery at a high state of charge by
using a lower charge voltage. Float charge is more important for grid backup systems and less
important for off-grid systems.
Full charge
Full charge is a charging process in the constant voltage phase. Full charge charges the battery to
approx. 95% at least once a month. This avoids premature battery aging caused by inadequate
charging.
Generator
An electric generator is an electrical machine which converts kinetic energy into electrical energy. In
off-grid systems, not only the electric generator itself, but also the combustion unit (diesel, petrol, or
gas motor) necessary for the power unit are simply referred to jointly as generator.
Grid-tie plant
PV plant which is connected to the electricity grid.
