Deye 12kW Three Phase Hybrid Inverter SUN-12K-SG04LP3-AU

Deye 12kW Three Phase Hybrid Inverter — SUN-12K-SG04LP3-AU

Power your world on your terms — higher yields, total control, zero compromise.

Meet the Deye SUN-12K-SG04LP3-AU, the three-phase hybrid inverter built for homes and businesses that refuse to settle. Pairing a robust 12kW output with intelligent low-voltage battery support, this powerhouse turns sunlight into savings while keeping you in command whether you are on-grid, off-grid, or somewhere in between.

Smarter from the start.

Thanks to Deye’s Smart Monitoring Platform, you can adjust parameters, push firmware updates, and even remotely shut down the system the instant something goes wrong — all from your phone. Plant maintenance has never been this effortless or this safe.

Engineered to flex.

Need balance? You’ve got it. The SUN-12K delivers 100% unbalanced output across each phase, with up to 50% of rated power available per phase. Already have a solar setup? The AC-couple function lets you retrofit your existing system instead of starting over. And when your energy demands grow, scale up to 16 units in parallel for seamless on-grid and off-grid operation, with support for multiple parallel batteries.

Battery muscle that lasts.

With a hefty 240A max charging and discharging current, 48V low-voltage compatibility (lead-acid or lithium-ion), and a transformer-isolation design for added safety, your stored energy is always ready. Six configurable time periods give you granular control over when to charge and discharge — and yes, it’ll even bank energy from your diesel generator when the sun clocks out.

Built tough, built efficient.

A peak efficiency of 97.60%, MPPT efficiency of 99.90%, and an IP65 protection rating mean this inverter sips losses and shrugs off the elements, indoors or out.
