Description
A rack with 8 modules has 29.0 kWh and a nominal voltage of 358.4 V, with 12 modules 43.5 kWh and 537.6 V, so the battery voltage must be checked against the DC input range of the specific UPS. The modules are built from LFP cells of 27 Ah. For 10 min the rack delivers 133 kW in the smaller version and 200 kW in the larger one, and at a lower load the backup time increases to 30 minutes. The life of over 2500 cycles is given for 1C/1C mode to 80 % SOH, that is, for a full charge and discharge in about an hour. The BMS is built into the rack, so the module state is monitored at the level of the battery itself. Compliance with IEC 62619 and UL 1973 is supplemented by fire tests under the UL 9540A method, which show the system behaviour during thermal runaway of a cell.
How to choose
The version is chosen by the UPS power and the required backup time. For a UPS up to 133 kW for 10 min, 8 modules are enough; up to 200 kW a rack with 12 modules is needed. If the UPS has a bipolar DC bus, the same reserve of 29.0 / 43.5 kWh is given by the LBM with a voltage of ±179.2 / ±268.8 V. For a data centre with a load of 400 kW for 5 min, the LZH at 47.1 kWh and over 4000 cycles is intended, and the UBH Gen3 and UZR Gen3 cabinets are built on NMC and deliver from 200 to 470 kW.

FAQ
What autonomy does the LZM LFP rack give for a UPS?
The design backup time is 10–30 minutes depending on the load; full power of 133 or 200 kW is held for 10 min.
What is the nominal voltage of the LZM battery system?
The 29.0 kWh version has 358.4 V, the 43.5 kWh version has 537.6 V DC.
How many cycles does the LZM LFP battery for UPS withstand?
Over 2500 cycles at 1C/1C to 80 % SOH, which is more than enough for mains outages and regular test discharges.
What certificates does the LZM battery rack have?
The rack is certified to IEC 62619 and UL 1973 and has passed UL 9540A testing for thermal runaway propagation.
How does the LZM differ from the LBM?
Both have 27 Ah LFP cells, a capacity of 29.0 / 43.5 kWh and 133 / 200 kW for 10 min. The LZM has a voltage of 358.4 / 537.6 V, while the LBM is designed for a bipolar bus of ±179.2 / ±268.8 V.
