Fogstar x LuxpowerTek Gen2 14k (Single-Phase Hybrid Inverter)
The GEN2-LB-EU 14K from Fogstar x LuxPowerTek is a high-output hybrid inverter for single-phase (230V) systems, aimed at larger residential and light-commercial energy storage installations and set up to integrate with compatible Fogstar Energy 48V (51.2V) batteries.
Rated at 14kW of grid-connected AC output and 12kW of UPS / backup output, the GEN2-LB-EU 14K brings together high-capacity solar input, powerful battery charging, backup capability and generator integration in a single, robust IP66-rated unit.
Three independent MPPTs, a maximum PV input of 18kW, 250A battery charge and discharge current and the option to run up to 10 units in parallel make it an adaptable choice for demanding single-phase hybrid systems.
