High-Capacity Three-Phase Energy Management

The TriP2-LB-3P 20K is built for installations where a standard single-phase hybrid inverter cannot provide the required power or system flexibility. Its three-phase output architecture supports demanding residential properties, commercial premises and light industrial applications with mixed electrical loads across multiple phases.

Support for unbalanced three-phase loads allows the inverter to respond more effectively where electricity consumption is not evenly distributed across each phase. Independent export control also allows grid export to be managed separately by phase, providing greater control in complex commercial and three-phase installations.

48V Low-Voltage Battery Integration

The inverter uses a 48V low-voltage battery architecture with a 40-60V operating range, providing an alternative to high-voltage battery systems while still supporting substantial energy throughput. Maximum battery charge and discharge current is up to 250A, with battery power of up to 12kW depending on the connected battery voltage.

Intelligent lithium battery charging includes BMS self-adaptation, helping the inverter and compatible battery management system work together to manage charging and discharging appropriately.

Generator and Smart Port

A dedicated GEN port provides additional flexibility for backup and hybrid power system design. It supports automatic generator start and stop control, smart load management and AC coupling functionality, allowing the inverter to manage supplementary generation alongside solar PV and battery storage.

Time-of-Use and Export Control

Eight configurable time-of-use charging and discharging periods allow the system to manage battery usage around changing electricity tariffs and demand patterns. This can help increase solar self-consumption, charge batteries during lower-cost periods and reduce grid imports during higher-rate periods.

Independent grid export control on each phase provides additional flexibility for three-phase properties, particularly where phase loads vary significantly or export limits need to be managed carefully.
