Deye SUN-25K-SG01HP3-EU-AM2

The inverter is the device that joins the panels, the battery and the grid into a coherent system: it converts solar power into usable power and sends it where it is needed, without anyone intervening. The high-voltage battery is built as a stack of modules and works with low current, which reduces losses and heating. The 25 kW model is the most powerful in its series and is aimed at buildings with significant consumption.

The 25.000 W supports in parallel the equipment of a small hall, a farm or an office, and the load can be 100% unbalanced between phases, so you can concentrate the consumption where it is needed. Up to 50 kWp of panels can be connected, of which the device processes at most 40 kW, a useful reserve in the morning and evening hours and on cloudy days. The battery charges and discharges at 50 A, and its management system communicates automatically with the inverter. The IP65 enclosure allows outdoor mounting, and above 45 degrees C the device reduces its power in a controlled way for protection. Remote monitoring is done through optional modules, so you can follow production and consumption from your phone.

Active power 25.000 W, maximum apparent 27.500 VA, three-phase output 220/380 V or 230/400 V, 50/60 Hz, 41,7/39,9 A maximum current per phase, 100% unbalanced load. DC side: 2 independent MPPT with 2 strings each, maximum voltage 1000 V, MPPT range 150-850 V, 26 A maximum working current on each MPPT, 39 A admissible short-circuit current, 50 kWp of modules connectable and 40 kW of processed DC power; maximum efficiency 97,6%, European 97,0%. Lithium-ion stack storage 160-700 V, 50 A on charge and 50 A on discharge, BMS communication via CAN/RS485. IP65, intelligent cooling, -40...+60 degrees C with derating above 45 degrees C, monitoring via RS485/RS232/CAN and optional WiFi, LAN, 4G or GPRS modules; compliance with IEC 61727, IEC 62116, EN 50549, VDE-AR-N 4105, CEI 0-21, UNE 217002, G98/G99.

Who it suits

Suitable for a commercial building, a small hall or a farm with up to 50 kWp of panels and high-voltage battery storage.

Terms explained

• kWp: The peak power of the panels, measured under standard laboratory conditions; it is the label according to which the installation is sized.
• Processed DC power: How much of the panel energy can actually pass through the inverter at a given moment; the rest is lost only in the very short summer peaks.
• Monitoring via WiFi, LAN, 4G or GPRS: Different ways of sending the data to the app, so that you can follow production even where there is no fixed internet.

Technical specifications

Recommended applications

• Commercial buildings and production halls
• Farms and irrigation systems
• Three-phase self-consumption with HV storage
• Systems with back-up for critical lines
