House / Business Loads
The junction box provides the required high-voltage DC and communication interfaces, allowing the battery and inverter to operate as an integrated energy-storage system.
Battery System Configuration
The PowerOcean three-phase system uses modular LFP batteries. EcoFlow documentation specifies approximately 5.1kWh per battery module, with configurations of one, two or three battery modules providing approximately 5.1kWh, 10.2kWh and 15.3kWh, respectively. The overall PowerOcean system can be expanded to substantially higher storage capacity depending on the applicable configuration.
The junction box therefore serves as an important connection component when integrating the battery stack with the PowerOcean inverter.
