Deye 29.9–50kW Three-Phase High-Voltage Hybrid Inverter
The Deye SG02HP3-EU-BM3/BM4-P combines PV generation, high-voltage battery charging and three-phase AC management in one wall-mounted inverter. Solarayen supplies original Deye-branded equipment for commercial solar-storage projects, installers and distribution enquiries. Available ratings are 29.9 / 30 / 35 / 40 / 50kW.
This series requires a compatible 160–800V high-voltage lithium battery. It is not a 48V-class battery inverter. Confirm BMS communication, battery operating voltage, current capability and the destination-country grid requirements when selecting a system.

Key Features
- 3 / 4 MPPT for PV array tracking; exact string limits depend on the selected model.
- High-voltage lithium battery support over the 160–800V operating range.
- Six programmable battery charging and discharging periods.
- AC coupling for suitable existing solar installations.
- Up to ten compatible units in parallel for on-grid and off-grid operation, according to Deye configuration requirements.
- Generator-supported battery charging for suitable systems.
- Unbalanced three-phase output supported within manufacturer phase and total-power limits.
- IP65 enclosure; installation still requires appropriate clearances, ventilation and weather protection.
Model Selection
The 29.9/30/35kW BM3-P models have three MPPTs and 2+2+2 strings. The 40/50kW BM4-P models have four MPPTs and 2+2+2+2 strings. Operating current is 36A per tracker; short-circuit current is 55A per tracker. The latest series lists one battery input, a 160A maximum battery charge/discharge rating and 200A continuous grid-to-load passthrough.
Technical Specifications
The following table follows the current Deye model data. PV access power and PV input power are separate ratings; use both when designing the array.

Frequently Asked Questions
Can this inverter use a 48V or 51.2V battery?
No. This series requires a compatible 160–800V high-voltage lithium battery. Confirm BMS compatibility and operating limits before pairing.
Does high-voltage battery support guarantee compatibility?
No. Battery voltage alone is insufficient. Check the approved BMS protocol, firmware, battery capacity, current limit and system configuration.
How many MPPTs are available?
BM3-P models at 29.9/30/35kW have three MPPTs. BM4-P models at 40/50kW have four MPPTs.
Can the phases supply different loads?
Deye supports unbalanced three-phase output. Phase-current and total-inverter limits still apply; confirm the selected model and load profile with the project design.
How long will battery backup last?
Runtime depends on usable battery energy, actual load, battery limits and conversion losses. The inverter kW rating alone does not determine backup duration.
Which warranty and approvals apply?
Deye lists five years with up to ten years depending on installation country and policy. Confirm exact model certificates, grid acceptance and warranty terms for the destination before ordering.
