Detailed description

Optimize your existing FOX ESS storage: Expansion module CS2900

The powerful high-voltage PV storage Fox ESS CS2900 offers a storage capacity of 2.88 kWh and is a retrofit component for the stackable PV storage ECS2900.

The complete ECS2900 system can be modularly expanded up to 20.16 kWh (6x CS2900 + 1x CM2900 with BMS) without any time limit. The total height of the PV storage system is 0.95 m. The modules can be expanded without any time limit , giving you complete independence when configuring and expanding your storage system.

Thanks to plug-and-play installation, the CS2900 high-voltage PV storage system is quickly commissioned. The individual PV storage modules are simply plugged into each other wirelessly . The data cable and battery connection cable, each 1.2 m long, are included. Therefore, no additional cables are required for commissioning.

Important: For operation with the Fox ESS H1 hybrid inverter, at least two PV storage modules are required: the CM2900 base module and the CS2900 battery module (min. 5.76 kWh). For combination with the H3 and H3 Pro hybrid inverters, you need at least three PV storage modules: one CM2900 base module and two CS2900 battery modules (min. 8.64 kWh).

Can be used anywhere and for a long time

Thanks to their high IP 65 protection rating, the ECS2900-H2 to H7 high-voltage PV complete storage systems are suitable for outdoor installation and can therefore also be operated in the garage or under a canopy. The particularly wide operating range of -10°C to +55°C (from approximately 0°C/15°C only discharging) ensures flexible use year-round.

The PV storage system ECS2900-H2 to H7 impresses with long-lasting LiFePO4 PV batteries with cyclic deep discharge of up to 6000 cycles, which enable a usable depth of discharge of 90% for self-sufficient solar energy.

The prismatic LFP cells for energy storage ensure a long service life . Compared to other LFP and cell technologies, they also offer the highest level of safety .

The innovative natural convection cooling of the ECS2900-H2 to H7 PV storage system ensures ear-friendly operation, significantly extends the lifespan of your battery, and simultaneously protects the environment . Enjoy the benefits of this innovative technology and benefit from maximum performance with quiet operation and an excellent energy balance.
