Steca Xtender XTH

3000-12, 5000-24, 6000-48, 8000-48

The basic functions of the combined inverter of the Steca

Xtender series are the inverter, the battery charger, the swit-

ching function and the support of external sources of alterna-

ting current. These functions can be combined and controlled

fully automatically, the range offers outstanding user-friendli-

ness and very good exploitation of the energy available.

All the settings of the Steca Xtender XTH can be remote con-

trolled. When a software with new functions is available, it

can be loaded into the system, so the Steca Xtender XTH

always stays up to date. Several Steca Xtender XTH can be

connected in parallel or to form a three-phase system. That

means that up to nine Steca Xtender XTH can work toge-

ther.

Multifunction contacts

These potential-free contacts can be programmed for many

different applications. They can react to any event outside or

inside of the inverter (grid availability, battery voltage, fault

message ...) They can also be programmed on a timer or can

be switched on during particular times (at night, at the week-

end ...). In this way, they can serve to start up a generator,

to switch off less important loads, to signal a fault, to charge

batteries depending on the situation, etc.

Smart-boost function

With the smart-boost function, the output of another source

of alternating current, such as a power generator or a land

connection, can be increased; even when special loads are

being used (inductive, asymmetric, with high switch-on cur-

rent). It is also possible to combine the Steca Xtender XTH

with almost all inverters which are already present in order to

increase the available output.
