Components of ESS-GRID FlexiO
P500E DC/AC 500kW
- 375 / 500kW Rated Power
- Integrated STS and Transformer Module
The P500E has a modular design with a built-in STS and transformer. With the P500E, you can transfer energy bi-directionally to the battery, grid and DG, helping you to achieve more functionality and maximise the benefits of your energy storage system.

P500E DC/AC 500kW
- 300 / 350 / 375 / 400 / 450 / 500kW Rated Power
- Maximum built-in 10 MPPTs
The P500L has a modular design and its main role is to convert the DC power generated by the PV panels into AC power for integration into the grid or for local use. At the same time, the P500L is equipped with features such as Maximum Power Point Tracking (MPPT) to maximise the efficiency of the PV system.
