Deye 29.9kW Three Phase Hybrid Inverter SUN-29.9K-SG01HP3-AU

Deye 29.9kW Three Phase Hybrid Inverter — SUN-29.9K-SG01HP3-AU-BM3

Power your world without compromise. The Deye SUN-29.9K-SG01HP3-AU-BM3 is a 29.9kW three-phase hybrid inverter engineered for homes and businesses that demand more more yield, more flexibility, and more peace of mind. With three MPP trackers and high-voltage battery support, it squeezes every available watt from your panels while keeping your energy smart, safe, and entirely under your control.

Why it stands out

Higher yields, smarter harvest. Three independent MPP trackers (with up to two strings each) and a max DC input of 44,850W mean your solar array works harder across changing light and shade conditions, hitting up to 97.6% peak efficiency and over 99% MPPT efficiency.

True 100% unbalanced output. Each phase can deliver full load independently perfect for real-world properties where power demand is never perfectly even.

High-voltage battery, higher efficiency. With a 160–800V battery range, dual battery inputs, and self-adapting BMS charging, you get faster, cooler, more efficient energy storage. Charge and discharge at up to 100A combined, and run multiple batteries in parallel as your needs grow.

Built to scale. Connect up to 10 units in parallel for both on-grid and off-grid operation a future-proof backbone for expanding solar and storage ambitions.

Retrofit-ready and generator-friendly. AC-couple it to an existing solar system without starting over, and store energy straight from a diesel generator when the grid goes quiet. Six configurable time periods let you fine-tune charging and discharging to match tariffs, usage, and lifestyle.

Reliable when it matters most. A rugged IP65 enclosure stands up to harsh conditions, while off-grid peak power of 1.5× rated output (for 10 seconds) handles demanding startup surges with ease.

What is the Deye SUN-29.9K-SG01HP3-AU hybrid inverter?
The Deye SUN-29.9K-SG01HP3-AU is a 29.9kW three-phase hybrid solar inverter designed for high-voltage lithium-ion battery storage. It has three MPPT trackers, accepts up to 44,850W of DC solar input, supports two battery inputs in the 160–800V range and delivers 100% unbalanced output on each phase. It suits large homes, farms and commercial sites that need high-capacity solar and storage from a single inverter.

What batteries are compatible with the Deye SUN-29.9K-SG01HP3-AU?
The Deye SUN-29.9K-SG01HP3-AU works with high-voltage lithium-ion batteries in the 160–800V range. It has two battery inputs, each supporting up to 50A of charge and discharge current (100A combined), and adapts its charging automatically to the battery’s BMS. Multiple batteries can be connected in parallel to expand storage.

What are the benefits of two battery inputs on the Deye 29.9kW hybrid inverter?
Two battery inputs let the Deye 29.9kW hybrid inverter connect two battery banks, each charging and discharging at up to 50A. Combined throughput reaches 100A, so a large storage system can absorb surplus solar and supply heavy loads faster than a single-input inverter.

Can I use a 48V battery with the Deye SUN-29.9K-SG01HP3-AU?
No, the Deye SUN-29.9K-SG01HP3-AU is designed only for high-voltage lithium-ion batteries in the 160–800V range and doesn’t support 48V low-voltage batteries.

How much solar can I connect to the Deye 29.9kW three-phase hybrid inverter?
The Deye 29.9kW three-phase hybrid inverter accepts up to 44,850W of DC solar input, a 1.5× ratio to its 29,900W AC output. Panels connect across three MPPT trackers with up to two strings each, and each tracker handles up to 36A of input current. That oversizing headroom captures more energy in low light and across large, multi-orientation arrays.

What are the PV string input specifications of the Deye SUN-29.9K-SG01HP3-AU?
The Deye SUN-29.9K-SG01HP3-AU accepts a maximum PV input voltage of 1,000V, with an MPPT range of 150–850V, a rated PV input voltage of 600V and a 180V start-up voltage. It has three MPPT trackers with a 2+2+2 string configuration and up to 36A of input current per tracker.

What is the AC output and passthrough rating of the Deye 29.9kW hybrid inverter?
The Deye 29.9kW hybrid inverter delivers 29,900W of rated AC output and UPS power, at 43.4A per phase. It has a 200A maximum continuous AC passthrough, so a large amount of grid power can flow through to your loads. In off-grid mode it supplies 1.5× its rated power for 10 seconds to handle startup surges.

What does 100% unbalanced output mean on the Deye SUN-29.9K-SG01HP3-AU?
100% unbalanced output means each phase of the Deye SUN-29.9K-SG01HP3-AU can supply its load independently instead of splitting output evenly across all three phases. It suits commercial and rural properties where heavy equipment on one phase would otherwise limit the whole system.

Can the Deye SUN-29.9K-SG01HP3-AU run off-grid?
Yes, the Deye SUN-29.9K-SG01HP3-AU supports both on-grid and off-grid operation and can store energy from a diesel generator when solar and grid power are unavailable.

Can I add the Deye SUN-29.9K-SG01HP3-AU to an existing solar system?
