Installation
7.3 Connecting SITOP BAT1600 battery modules to the UPS module
By connecting up to 6 SITOP BAT1600 battery modules of the same type in parallel, battery
modules with a low rating can be connected to a SITOP UPS1600 with a higher power rating.
The following table lists the recommended combinations of SITOP UPS1600 and SITOP
BAT1600 battery modules.
Battery modules
SITOP BAT1600 2.5 Ah Li
SITOP BAT1600 3.2 Ah Pb
SITOP BAT1600 7.5 Ah Li
SITOP BAT1600 12 Ah Pb
SITOP BAT1600 38 Ah Pb
X is a recommended combination
O is a combination that is not recommended
By connecting two identical battery modules in parallel, this type can also be used with a
-1
SITOP UPS1600 20 A system.
By connecting two identical battery module types in parallel, this type can also be used with
-2
a SITOP UPS1600 40 A system.
Connecting battery modules from third-party manufacturers to the SITOP UPS1600
Batteries from other manufacturers can be used. However, note that without a data interface
there is no full BMS functionality. Automatic temperature compensation of the end-of-
charging voltage is not possible. When manually configuring the energy storage, carefully
observe the data provided by the battery manufacturer and continually monitor the charging
parameters! It is only permissible to connect battery modules using "Pb technology" or "pPb
technology"!
Note
Connecting third-party battery modules
When connecting third-party battery modules, data connection via the COM connections is
not possible.
Note
If third-party battery modules are to be used, then all of the modules connected to a UPS
module must be of the same type. The connected modules must have the same technological
parameters and the same service life.
Note
When using third-party battery modules, the approval according to IEC62368-1 and UL61010
is no longer valid.
