ROH-F-P20 Series All-in-one Energy Storage System
Modular energy storage system: Advanced ROH-F-P20 with dual PV input maximizes solar efficiency, offering a scalable solution for reliable power management.
The ROH-F P20 series is an all-in-one energy storage system that combines lithium batteries with off-grid energy storage inverters. This product can accommodate up to 6 lithium battery modules and 1 off-grid energy storage inverter host. Each lithium battery module has a capacity of 5.12 kWh, with a maximum configurable capacity of up to 30.72 kWh.
The off-grid energy storage inverter host integrates grid/oil generator charging, solar charging, utility bypass, inverter output, and smart energy management. Multiple charging and AC output modes are available for users to select and configure, allowing flexible utilization of solar energy or grid power, achieving high-efficiency energy utilization.
Simplified product installation is achieved through modular stacking, supported by a swivel caster base for easy mobility. Users'
demands for high-capacity energy storage power are met through combinations of the main unit with varying numbers of batteries.
