PV plant
Term for a solar energy system for power generation. This includes all components needed for
collecting and utilising solar energy. In the case of grid-tie plants, this includes the PV array as well as
the PV inverter.
Quick Configuration Guide
The Quick Configuration Guide (QCG) is used to configure the settings required for operation. Step
by step, the QCG prompts you to make the settings required for the off-grid system. Parameters for a
cluster are set centrally at the master. All slaves take on the configuration automatically.
Sealed lead acid battery
Battery type where the electrolyte is bound in a gel. This is a type of closed lead acid battery. A
hydrogen and oxygen gas mixture is always generated when lead acid batteries are charged, and
in normal operation this mixture undergoes internal recombination to form water. Hence, there is no
need to regularly top up water, which is why these batteries are often described as low maintenance
or even maintenance-free batteries (see also AGM batteries). There are sealed lead acid batteries for
high-current applications but also for cycle operation with very high cycle resistance.
Search mode
Search mode is an energy saving mode. At regular intervals, the off-grid inverter checks whether loads
are connected to the system. If the off-grid inverter does not detect any loads, the off-grid inverter
switches to search mode. Once a load is connected, the off-grid inverter exits search mode and
switches to normal operation.
Self-discharge
Charge loss of a battery cell while it is stored or unused. A higher ambient temperature has a strong
influence on self-discharge.
Series connection
The positive pole of each battery is connected to the negative pole of the next battery. There is only
one circuit where current can flow. Series connection increases the voltage of the battery system. If
two 24 V batteries with a capacity of 100 Ah each are connected in series, the total voltage is
24 V + 24 V = 48 V, while the total capacity remains at 100 Ah.
Silent mode
Silent mode is an energy saving mode for grid backup systems. If a configurable time for the float
charge has expired, the off-grid inverter switches to standby mode. The off-grid inverter is then in
standby mode. If the electricity grid fails when in standby, the off-grid inverter provides a stand-alone
grid within seconds.
