Detailed description

Easy scaling and installation

The powerful high-voltage FoxESS ECS4300H series PV storage system offers a storage capacity of 8.29–29.03 kWh . It consists of the CM4300 base module with integrated battery management system and the CS4100 battery modules. Thanks to its modular design, a total of seven PV storage modules, each with a capacity of 4.14 kWh, can be stacked on top of each other, achieving a capacity of 29.03 kWh. The modules can be expanded at any time .

Thanks to plug-and-play installation, the 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 CM4300 base module and the CS4300 battery module (min. 8.29 kWh). For the 3-phase Fox ESS H3 and H3 Pro hybrid inverters , at least three PV storage modules are required: the CM4300 base module, and two CS4300 battery modules (min. 12.144 kWh).

Can be used anywhere and for a long time

Thanks to their high IP 65 protection rating, the ECS4300-H2-H7 high-voltage PV storage systems are suitable for outdoor installation and can therefore also be operated in a 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 ECS4300H - H2-H7 consists of deep-cycle and safe LiFePO4 HV batteries that achieve over 6000 cycles and have a depth of discharge of 90% .

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.

Natural convection cooling allows for quieter operation and a longer service life
