Proper use
The Powerstocc DC Storage converts DC current into AC current.
The current can be used for the following:
n for consumption
n to store the current in the battery of the system (BS DC Storage 11.6 Pb)
n for feeds into the public mains grid
The unit may only be used in grid-connected photovoltaic systems within the
permissible power range and under the permissible environmental conditions.
The device is not intended for mobile use.
Inappropriate use can be hazardous and lead to injury or even death of the user
or third parties. Material damage to the device and other equipment can also
occur. The inverter may therefore only be used for its intended purpose.
The Powerstocc DC Storage is equipped with an energy management system.
This system controls based on technical and economic aspects of the use of
electricity generated.
Exclusion of liability
Any use that diers from or goes beyond the stated intended purpose is con-
sidered inappropriate. The manufacturer accepts no liability for any damage
resulting from this. Modifications to the inverter are prohibited. The inverter may
only be used if safe to operate and in technically perfect condition. Any instance
of misuse will cause the termination of the warranty, guarantee and general
liability of the manufacturer.
Only a qualified electrician may open the device. The inverter must be installed
by an electrician who is responsible for observing the applicable norms and
regulations. Work that could aect the electrical power system of the respective
utility company at the site of the solar energy feed-in may only be carried out by
qualified electricians expressly authorised (licensed) by the utility company.
This includes changes to the factory preset parameters. The installer must
always observe the regulations of the utility company. The utility company‘s
specifications must always be observed when setting the parameters.
