TESVOLT produces a range of lithium batteries specifically designed for commercial storage applications in combination with SMA inverter/chargers. The batteries use Samsung SDI’s ultra-safe, high-grade prismatic lithium NMC cells.
The principal advantage offered by TESVOLT is its innovative Active Battery Optimisation, which individually balances the state of charge of each cell using bi-directional flyback converters (as opposed to uni-directional ‘charge pumps’). This allows for fast and efficient balancing of cells within a stack, which is necessary to prolong the life of the cells. As a result, TESVOLT batteries are extremely long-lived, with components designed to last up to 8,000 cycles and a lifespan of 30 years.
There are two main products ranges available: the TS system, which is suitable for off-grid and backup requirements; and the TS HV system, which is tailored towards high power applications and the provision of ancillary services.
TESVOLT’s TS storage systems are built up using 4.8 kWh battery modules in parallel configuration, connected to any chosen size and number (up to 12 on-grid, 36 off-grid) of SMA Sunny Island stand-alone inverter/chargers. This enables a wide range of possible configurations, ranging up to 72 kW/1.2 MWh for grid-connected systems and over 200 kW/3 MWh in off-grid applications. The batteries can provide continuous discharge rates of 1C (full discharge in 1 hour).
Every TS battery module includes its own Active Battery Optimiser (ABO). This ensures each battery module is optimally maintained and facilitates easy servicing, with the ABO able to be separated from the battery if required.
The TESVOLT TS series is suitable for the following applications:
TESVOLT's TS HV systems utilise a high voltage configuration of the battery modules (modules connected in series to yield voltages ranging from 600 V), and are optimised for use with SMA Tripower Storage 60 inverter/chargers.
The individual TS HV storage units come with a capacity of 67 kWh and up to 4 of these can be combined for one SMA inverter/charger. System sizes up to 600 kW/2.7 MWh can be achieved, with the batteries able to deliver continuous power output of 1C rate as for the TS series.
The TESVOLT TS HV series is suited to the following applications:
TESVOLT TS HV battery systems cannot be used for backup or off-grid applications, however.
