Deye 18kW Hybrid Solar Inverter SUN-18K-SG01LP1-EU-AM3-P

18kW Single Phase | 48V Battery | 3 MPPT Trackers | 36kW Maximum PV Array

When a standard residential solar inverter isn't enough, the Deye SUN-18K-SG01LP1-EU-AM3-P offers the additional capacity needed for larger homes, farms and commercial installations. This is South Africa's largest Deye single-phase hybrid low-voltage (LV) inverter. The unit comes with a standard 5-year warranty, which can be extended to 10 years when paired and installed with a properly sized, compatible battery bank.

This 18kW single-phase hybrid solar inverter combines solar generation, battery storage, Eskom electricity and generator support in one energy management system. It is designed for properties with high electricity consumption where reliable backup power and reduced grid dependence are important.

With three independent MPPT trackers, support for 48V-class battery systems and a maximum PV array capacity of 36kW, the Deye 18kW inverter offers considerable flexibility when designing a larger solar installation.

Its impressive 380A maximum battery charging and discharging current also makes it suitable for substantial low-voltage battery storage systems.

Whether you're planning a new solar installation or expanding an existing setup, the SUN-18K-SG01LP1-EU-AM3-P provides the capacity and flexibility to manage demanding energy requirements.

Why Choose the Deye SUN-18K-SG01LP1-EU-AM3-P?

18kW Single-Phase Power Output

With a rated AC output of 18,000W and maximum apparent power of 19,800VA, this inverter is designed for properties with substantial electricity requirements. It is suitable for larger homes, guest houses, farms, workshops and selected commercial installations.

Three Independent MPPT Trackers

The three MPPT trackers provide flexibility when connecting solar panels across different roof orientations or installation areas. Each tracker supports two PV strings, allowing for a versatile solar panel configuration.

Up to 36kW Solar PV Array Capacity

The inverter supports a maximum PV array capacity of 36kW, making it suitable for installations requiring substantial solar generation.

This allows you to design a larger solar array to support daytime electricity consumption and battery charging, while remaining within the inverter's specified PV input limits.

High-Current 48V Battery Support

The Deye SUN-18K-SG01LP1-EU-AM3-P supports compatible lithium-ion and lead-acid batteries operating between 40V and 60V.

With maximum battery charging and discharging currents of 380A, it provides substantial power handling for large battery storage installations.

The inverter also supports battery management system communication, allowing compatible lithium batteries to coordinate charging and discharging with the inverter.

Backup Power During Load Shedding

When connected to a suitable battery bank, the inverter can provide backup electricity when Eskom supply is interrupted.

It is particularly useful for larger households and businesses that need to keep refrigeration, lighting, security systems, pumps, computers and other essential equipment operational.

Eskom and Generator Integration

The hybrid inverter manages solar generation, battery storage, grid electricity and generator input. It also supports storing energy from a diesel generator, providing additional flexibility when solar production and battery reserves are insufficient.

Six programmable battery charging and discharging time periods allow you to manage energy usage according to your requirements.

AC Coupling for Existing Solar Systems

The inverter supports AC coupling, making it an option for certain existing solar installations that need to be upgraded with additional battery storage or hybrid energy management.

Expandable System Capacity

For larger installations, up to 16 units can operate in parallel in supported configurations. Multiple compatible batteries can also be connected in parallel, subject to the manufacturer's system design requirements.
