The Luxpower GETA 3.6K/24V Hybrid Inverter is a compact 3600W pure sine wave inverter designed for residential solar backup, essential appliance circuits and small off-grid power systems.
Its high-voltage MPPT solar input supports up to 4000W of PV capacity and a maximum PV input voltage of 500V. This allows compatible solar panels to be connected in longer series strings, helping to reduce PV cable current and simplify suitable installations.
Dual AC outputs provide intelligent load management by separating essential and secondary appliances. This allows the system to prioritise important loads while controlling less critical equipment according to the available battery capacity, solar production and programmed operating mode.
The inverter is compatible with both lithium-ion and lead-acid batteries and includes battery activation from either solar power or the utility grid. Built-in Wi-Fi enables continuous remote monitoring, giving users access to system performance and operating information throughout the day.

System Sizing Notice:
The inverter can supply a maximum rated output of 3600W. The total continuous appliance load must remain within this limit.
Appliances with motors, compressors, pumps or heating elements may draw substantially more power during start-up or operation. The installer must calculate the continuous load, surge demand, battery capacity and required backup time before commissioning the system.
The inverter output rating does not determine battery runtime. Runtime depends on:
Battery storage capacity
Usable depth of discharge
Total connected load
Inverter efficiency
Battery condition
Solar production during use
Configured operating limits
Solar Panel Configuration:
Solar panels must be configured so that the complete string remains within the following inverter limits:
Maximum array power: 4000W
Maximum open-circuit voltage: 500V
MPPT operating voltage: 55V–440V
Maximum MPPT input current: 18A
Start-up voltage: 65V
The solar string voltage must be calculated using the panel open-circuit voltage and the expected minimum site temperature. Exceeding the inverter’s maximum PV voltage or current can damage the inverter and may invalidate the warranty.
