12kW Output with 13.2kW Usable PV Input
The inverter delivers 12kW rated AC output and supports up to 13.2kW usable photovoltaic input. Its PV section supports 500V maximum DC voltage and a 125–425V MPPT operating range. Final string voltage must be calculated from the selected panel specifications and site conditions.
Dual MPPT for Flexible Rooftop Design
Two MPPT trackers with a 2+1 string arrangement help installers manage arrays on different roof faces or under different sunlight conditions. The specified MPPT input current for this model is 40A + 22A.
40–60V Battery Support and 200A Charging
The DEV-HYD-12KW supports 40–60V lithium and lead-acid batteries. The maximum specified battery charging current is 200A. Battery brand, BMS protocol, current limits, cable size, fuse rating and capacity must be approved during system design.
Fast Backup and Starting-Load Support
The backup output has a specified transfer time below 10 milliseconds. The off-grid output can provide two times rated power for up to 10 seconds for compatible starting loads. Continuous load must remain within the inverter rating, and the complete battery and wiring system must support the required current.
Generator Integration and Time-of-Use Management
A dedicated generator connection supports energy management with a compatible generator. The inverter also supports time-of-use operation, including configured grid charging and battery discharge schedules, subject to local rules and commissioned settings.
IP66 Protection, Smart Cooling and Parallel Expansion
The IP66 enclosure resists dust and strong water jets when installed according to the official manual. It must not be submerged or installed in flood-prone, corrosive or poorly ventilated locations. Smart cooling, less than 5W specified self-consumption and an operating range of -25°C to 60°C support demanding installations, with output derating above 45°C. Up to six matching units can be configured in parallel by a qualified installer.
