Low-voltage lithium batteries
In low-voltage systems, the battery operates at a DC voltage of around 48 V (51.2 V nominal) or around 24 V (25.6 V nominal). The catalog includes products such as the 51.2 V 100 Ah PB Series, the 25.6-51.2 V Modular Series (with a metal base) and the 25.6 V 204 Ah G2 modular battery. These lithium iron phosphate based modules are compact and designed for a large number of charge-discharge cycles.
Areas of use
- Residential systems with single-phase low-voltage hybrid inverters
- Vineyard houses and holiday homes running on a smart (off-grid) inverter
- Stepwise investments where capacity is to be added later
Selection criteria
- System voltage: The inverter's battery input must suit the 24 V or 48 V class.
- Capacity: Multiplying the Ah value by the voltage gives the kWh equivalent; daily consumption should be compared accordingly.
- Communication: Protocol compatibility between the battery management system and the inverter is critical.
- Parallel connection: How many modules can be connected in parallel is verified from the product documentation.
Antalya note
In summer temperatures, the placement and ventilation of the battery matter for its lifespan. The installation area should preferably be shaded and cool.
