Deye 5kW Hybrid Inverter SUN-5K-SG04LP1-EU-SM2 overview

The Deye 5kW Hybrid Inverter SUN-5K-SG04LP1-EU-SM2 forms part of Deye’s SG04 low-voltage hybrid inverter series, engineered to combine solar charging, battery management, and AC power conversion in a single compact unit. This model is designed for modern energy systems that require flexibility, efficiency, and dependable backup power.

Built around a 48 V battery platform, the inverter produces pure sine wave output, making it suitable for household appliances, office equipment, and sensitive electronics.

How the Deye SUN-5K-SG04LP1-EU-SM2 works

The Deye SUN-5K-SG04LP1-EU-SM2 intelligently manages power from multiple energy sources:

• Solar PV during daylight hours

• Battery storage for energy shifting and backup

• Grid or generator input when required

Solar energy is prioritised to supply loads and charge batteries. When solar production is insufficient, the inverter seamlessly switches to battery or AC input, ensuring continuous power without user intervention.

Solar charging and MPPT optimisation

This model features an integrated MPPT (Maximum Power Point Tracking) solar charge controller with high tracking efficiency. The MPPT continuously adjusts operating parameters to extract the maximum available power from connected PV strings, improving solar yield under changing irradiance conditions.

The inverter supports flexible PV array configurations within its defined voltage and current limits, simplifying system design.

Battery compatibility and hybrid flexibility

The SUN-5K-SG04LP1-EU-SM2 is designed for low-voltage (48 V) battery systems and supports both lithium-ion and lead-acid batteries. Lithium batteries communicate via BMS for intelligent charging control, while lead-acid batteries are supported through configurable charge parameters.

Hybrid functionality allows the inverter to operate in backup, off-grid, or hybrid modes depending on site requirements and system configuration.

Backup power and load-shedding performance

During grid outages or load-shedding events, the inverter automatically switches to battery operation to maintain power to connected loads. Fast transfer times minimise disruption, making it suitable for essential residential and light commercial backup applications.

Pure sine wave output ensures safe operation of sensitive electronics and motor-driven equipment.

Typical applications

The Deye 5kW hybrid inverter SUN-5K-SG04LP1-EU-SM2 is suitable for:

• Residential homes with solar and battery storage

• Backup power systems for load-shedding

• Small offices and light commercial installations

• Hybrid systems with optional generator support

Its compact design makes it ideal where wall space and installation footprint are limited.
