Many battery inverters + one battery = reliable and efficient energy storage

The battery inverters can be operated in parallel on the DC side. This allows for multiple inverters to be connected to a single battery with a large capacity. The advantages are highest system availability and efficiency of the energy storage system.

Ready for all kinds of energy storage and grid management applications

The blueplanet gridsave 50.0 TL3-S is deployed between battery storage and power grid and can be connected in parallel on the AC side without a limitation in number. The power grid can be the national grid, a power supply of a small town or industrial facility: The size of the storage system is scalable according to requirements for decentralized applications up into the megawatt range.

By supplying stored energy in times of high energy demand, the battery inverter regulates energy peaks. Charging and discharging batteries, it also provides grid support by compensating reactive power or supplying additional active power.

Open communication standard

The blueplanet gridsave 50.0 TL3-S is controlled by an external Energy Management System (EMS). For that purpose, the inverter communicates via open Sunspec Modbus TCP for use with different EMS's. This widespread interface allows for a large number of available controllers to manage the energy storage system. The blueplanet gridsave 50.0 TL3-S can therefore easily meet individual requirements in the design of the storage application.

The blueplanet gridsave 50.0 TL3-S is approved according to BDEW and ISO.
