1. Introduction
The savebox H is an energy storage unit that will supply the stored energy on a single phase.
Available capacities are 4,5kWh and 7,5kWh.
The battery pack is charged by a PV and/or grid!
Thus the stored energy may be used to reduce the overall power drawn from the grid. For
instance during peak hours, consumption may increase and therefore cause a change in
tariff.
The nominal power rating of the savebox H is 2,6 kW. If the power demand is higher than the
nominal 2,6kW, the remaining demand will automatically be supplied via the grid. For
example, if the demand suddenly goes up to 6kW, the savebox H supplies 2,6kW and
therefore the remaining 3,4kW will be supplied via the grid. There is no switching delay as
the inverter is constantly synchronised with the grid and ready to supply. So your “saving”
in this example is in fact the 2,6kW, instead of a total of 6kW from the grid.
Under “island” conditions or during a grid failure (identical situation ! ), the savebox H will
automatically supply the island-grid with 2,6 kW (nominal !) of power until the batteries are
empty. Any increase in power(ie. higher load), above the nominal 2,6kW rating, will obviously
reduce the supply time as well as cause overheating which in turn will cause the inverter to
shut down – activating the emergency stop switch. The actual supply time depends solely
on the level of overload. Clearly, the best solution is obviously, to reduce the load, i.e.
keeping the supply at a max. 2,6kW.

Power surges up to 6kW will cause the savebox H to shutdown within 10s. The savebox H will
automatically attempt to reconnect to the load 3 times. Provided the load has been
reduced, reconnection will take place. However, if after 3 attempts have failed, the load is
obviously still to high and the savebox will no longer reconnect.
Installation of this unit is relatively straight forward. The walling must be capable of
supporting approx. 150 kg.
The savebox H can only be installed indoors.
All input, load, grid, Ethernet and auxiliary cables can either be fed into the housing through
openings at the base or from the wall outlet directly into the centre of the housing

Remember: Do not lift heavy objects alone ! Always seek assistance !
3.1. Danger to life due to high voltages of the PV array !
When exposed to sunlight, the PV array generates a dangerous, high DC voltage which
is present in the DC conductors and the live components of the inverter. Touching the
DC conductors or the live components can lead to lethal electric shocks. If you
disconnect the DC connectors from the inverter under load, an electric arc may occur
leading to electric shock and burns.
• Never touch non-insulated cable ends.
• Never touch the DC conductors.
• Never touch any live components of the inverter.
• Only qualified personnel may install and commission this equipment.
• If an error occurs, have it rectified by a certified technician only.
• Prior to performing any work on the savebox H , disconnect it from all voltage
sources (eg. combiner boxes etc.) as described in this document.
3.2. Danger to life due to electric shock
• Touching an ungrounded PV module or array frame can cause a lethal
electric shock. Connect and ground the PV modules, array frame and
electrically conductive surfaces so that there is continuous earthing.
Observe the applicable local regulations.
• Handle grid connection with respective caution !
Never disconnect load feed from savebox H before switching all loads off first ! Arcing !

4. Product Description
The savebox H has been designed to reduce the cost of power consumption. The internal
battery pack can be recharged by the attached PV-Array. The recharge process
automatically begins once the battery capacity has reached a certain low level .
Additionally the savebox H will act as a power supply during power cuts. Obviously it
can only provide power until the battery´s capacity has been depleted.
Two auxiliary outputs are provided, see 8.2.14. Both contacts are switched on
automatically, as soon as enough PV-Power is available. See NFC-Manual.
Note: The savebox H is a single phase unit !
