Deye 15–25kW Three-Phase High-Voltage Hybrid Inverter
The Deye SG02HP3-EU-DM3 integrates PV generation, high-voltage battery charging and three-phase AC power management. Solarayen supplies the original Deye-branded equipment for larger homes, small commercial projects, installers and distribution enquiries. Available variants are 15 / 20 / 25kW.
This series requires a compatible 160–700V high-voltage lithium battery system. It cannot connect directly to a 48V or 51.2V battery. Confirm the battery BMS protocol, firmware, usable voltage range and current capability against the exact inverter model.
Conceptual application illustration. The final installation follows the approved system design and manufacturer instructions.

Model Selection and Input Limits
Choose 15, 20 or 25kW. All models have three MPPTs with asymmetric string inputs: 2+1+1. Maximum operating current is 36+20+20A, and short-circuit current is 54+30+30A. These limits are per tracker, not three identical 36A inputs.
Maximum PV input power is 24, 32 or 40kW respectively. The series has one battery input, a 55A maximum charge/discharge current and 60A continuous grid-to-load passthrough.

Frequently Asked Questions
Can this inverter use a 48V or 51.2V LiFePO4 battery?
No. It requires a compatible 160–700V high-voltage lithium battery system.
Does the entire battery voltage range deliver full rated power?
Not necessarily. Available battery power depends on battery voltage, inverter current limits, battery BMS limits and operating conditions. Size the battery system against the required charge/discharge power.
How many MPPTs and strings are supported?
Three MPPTs with 2+1+1 strings. Operating current is 36+20+20A.
How should the battery current rating be read?
The maximum charging/discharging current is 55A through one battery input.
How long will backup power last?
Backup runtime depends on usable battery energy, actual load, battery limits and conversion losses. The inverter kW rating alone does not determine backup hours.
What approvals and warranty apply?
Confirm exact model certificates, destination-country grid acceptance and warranty terms before ordering. Deye lists five years with up to ten years depending on country and warranty policy.
