ECS is a high-performance, scalable battery storage system. The modular design allows for maximum flexibility, making it suitable for a broad range of storage applications. Additional batteries can be installed in series, allowing for a maximum storage capacity of 28.21 kWh. Installation is easy, with a plug and play solution that can save valuable time for installers.
This battery requires a MINIMUM of 2 modules to work (Master + Slave) for H1/KH1/H3 Smart and 3 modules for H3/H3 Pro inverters. This battery can have a MAXIMUM of 7 modules in a stack (1x Master + 6x Slaves)
If upgrading an existing system make sure it is a V2. ClearRay Solar have only received V2 of the 4100 battery model, and as such there should be no compatibility issues when installing new systems or expanding existing systems when the original batteries were purchased from ClearRay Solar.
