Description
LiFePO4 cells resist overheating better than NMC and tolerate daily cycling better, so LFP chemistry is chosen for batteries in residential houses. The recommended current of the module is 75 A and the maximum is 100 A, and for 15 s it delivers up to 200 A, which is enough for the starting current of a pump, compressor or power tool. The cell state is monitored by an in-house BMS, which watches voltage and temperature and exchanges data with the inverter. System capacity is increased by connecting modules in parallel to a common 51.2 V bus, and the voltage does not change, while the permissible number of modules is set by the inverter documentation. Low voltage means high currents, so cables and protection between the module and the inverter are sized for at least the maximum 100 A.
How to choose
The choice between the L5.1 and the larger module of the series is determined by the battery input voltage of the inverter. For a low-voltage hybrid inverter the L5.1 is taken and the required energy is built up by the number of 5.12 kWh modules. For a high-voltage inverter or a commercial site the e.module H10.2 of 10.24 kWh and 140 A is better suited, assembled into a string of up to 18 modules with a voltage of 48–1000 V.

FAQ
How much energy does the e.module L5.1 store?
The nominal energy is 5.12 kWh at a voltage of 51.2 V. The usable part is determined by the discharge limits set by the BMS and the inverter settings.
What discharge current does the 51.2 V LFP module allow?
The recommended current is 75 A, the maximum is 100 A, and the peak is 200 A for 15 s. If the inverter needs more, the modules are connected in parallel and the load is shared between them.
What is the weight and size of the e.module L5.1?
The weight is 47.5 kg and the dimensions are 442×459×160 mm. The module is carried by two people, and the floor or rack for several modules is checked for load.
Which inverters does the e.module L5.1 work with?
The module is declared compatible with inverters of leading brands. The specific inverter model and the communication protocol with the BMS are checked against the compatibility list before purchase.
