6kW 48V Solar Inverter with 9kW PV Input and 9 - Unit Parallel Support
This 6kW 48V solar inverter combines pure sine wave AC output, MPPT photovoltaic charging, battery operation, compatible AC input and parallel expansion in one single-phase power platform.
It provides 6kW of continuous output and 12kVA of short-duration surge power. The configuration can be considered for residential properties, home offices, shops and small business systems with lighting, refrigeration, computers, communication devices and compatible motor-driven loads.
The photovoltaic charger supports up to 9kW of solar input with two listed input-current channels of 19A + 19A. Up to nine compatible inverter units can also be configured in parallel when a project requires higher output capacity or future system expansion.
9kW Photovoltaic Capacity
The MPPT charger accepts up to 9000W of photovoltaic input for daytime load supply and battery charging within the specified electrical limits.
Dual 19A PV Inputs
The specification lists two photovoltaic input-current channels of 19A + 19A for suitable solar string configurations.
12kVA Starting Headroom
Short-duration surge capacity provides additional starting headroom for compatible pumps, compressors and other motor-driven equipment.
Nine-Unit Parallel Support
Compatible inverter units can be combined for expandable projects when wiring, communication, protection and commissioning follow the approved design.
The formal parameter table lists an 80–520Vdc photovoltaic operating range and a maximum open-circuit voltage of 500Vdc. The final solar string arrangement should therefore be confirmed against the latest approved technical specification before installation.
The combined continuous AC load should remain within 6kW. The 12kVA rating represents short-duration surge capacity and does not mean that one inverter can continuously supply 12kW.
Parallel installations require coordinated AC wiring, battery-bank capacity, communication cables, protection devices and matching inverter settings. The number of units should be selected according to the actual load schedule rather than the maximum supported quantity alone.
Battery capacity determines operating duration and must be selected separately from inverter power. Increasing the battery reserve extends runtime but does not increase the continuous output of one inverter.

This page focuses on solar charging, battery backup and parallel-system applications. It does not claim electricity selling or power export to the grid.
No. Continuous output is 6kW. The 12kVA value represents short-duration surge capacity for compatible starting loads.
The charger is rated for up to 9000W with two listed input-current channels of 19A + 19A. Final solar string design must follow the approved voltage limits.
The specification lists parallel support for up to nine compatible units. Final quantity depends on the project load and approved installation method.
Compatible equipment may be supported when its running power, startup demand and combined load remain within the inverter limits.
WiFi monitoring is listed as optional. The formal communication interfaces include LCD, RS485, USB, dry contact and CT/Meter connections.
This solar inverter is suitable for distributors, installers and system integrators requiring high photovoltaic input, strong starting-load capacity and future parallel expansion.
