Function, scope of delivery and technical parameters

The energy storage system VARTA pulse neo is intended for operation on the 230 V house network
and offers the option of connecting a separate grid-connected photovoltaic system. The latter must
be a generation system that feeds in not at full infeed, but after excess.
The energy storage system serves to increase the percentage of self-consumption and the economic
efficiency of a photovoltaic system. If the photovoltaic system produces more electricity than is im-
mediately consumed, it can be stored intermediately in the energy storage system. The electricity is
fed into the house network again from the store as soon as the consumption is bigger again than the
electricity quantity generated by the photovoltaic system. The energy storage system is integrated
into the house network on the alternating current side and works independently of the photovoltaic
system. A current sensor controls the charging and discharging processes of the energy storage sys-
tem. It is mounted in the fuse box directly after the consumption/feed-in meter and measures all
incoming and outgoing currents.
If the current sensor measures outgoing currents while there is available free charging capacity of
the energy storage system, the latter is charged. In the process, the batter converter in the energy
storage system converts the alternating current into direct current and charges the battery module.
If the maximum charging capacity is reached or if the solar-produced electricity exceeds the maxi-
mum charging current, the excess solar power is fed into the public network. If the photovoltaic sys-
tem cannot cover the current electricity requirements in the house, the current sensor measures
incoming currents. Thereupon, the energy storage system issues power into the house network in
order to minimise the external volume of purchased electricity and the associated costs.

Note:

Before installation of the VARTA energy storage system, it must be clarified with the respective

energy supplier/electricity grid operator whether it is necessary to register the system.

Derating

Derating means a temporary curtailment of the maximum performance of the battery converter in
order to prevent components from being heated excessively. VARTA energy storage systems are de-
signed in such a way that when the operating and environmental conditions are complied with the
permitted operating temperature is not exceeded and a derating is not necessary. To avoid a temper-
ature derating of the energy store, you should ensure that the energy store can issue the heat to the
ambient air.
Frequent temperature-induced derating can have the following causes:

The system cannot issue enough heat to the ambient air because the air filter is soiled or the
ventilator has failed.

The installation site of the energy store does not offer the requisite climatic conditions.
