Available with 5 kW or 8 kW hybrid inverter configurations and matched 5 kW or 8 kW lithium battery stacks. Each inverter supports up to six battery stacks to accommodate increasing capacity requirements. Battery stacks are cross-compatible: a 5 kW battery can be stacked on an 8 kW system, and an 8 kW battery can be stacked on a 5 kW system.
System oversight is provided through an integrated monitoring and control mobile application, enabling real-time status viewing, configuration, and performance analytics.
The all-in-one architecture is optimized for residential deployment and supports modular scaling by adding additional battery stacks per inverter.
Protective features include IP65 environmental sealing, integrated fire suppression, and temperature-controlled operation for enhanced safety and equipment longevity.
Engineered for stable daily operation and backup functionality within a compact footprint suitable for modern homes.
