HBOWA supplied a 160kW solar plus storage system for a project in Papua New Guinea. The system includes a full rooftop solar PV installation, 314kWh high-voltage battery storage, and two 80kW Deye three-phase high-voltage hybrid inverters.

This project is designed for solar microgrid operation, helping the customer use more on-site solar energy and maintain a more stable power supply.

Project Overview

Customer Challenge

The customer needed a more stable power solution for daily operation. In local island and remote-area in Papua New Guinea, grid power is limited and unreliable to rely on continuously. They wanted to make better use of rooftop solar power and needed battery storage to support energy use when solar generation was not available at night and during rainy days, as it rains often there.

Energy Storage Solution

HBOWA provided a 160kW solar plus 314kWh battery storage system with two 80kW Deye three-phase high-voltage hybrid inverters.

The system supports:

• Rooftop solar power generation
• Solar self-consumption during the daytime
• Battery storage for excess PV energy
• Night-time and rainy days provide power support
• Microgrid operation for local energy use

Project Benefits

• Higher Solar Self-Consumption
  Stores rooftop solar power for solar use.
• Stable Microgrid Operation
  Supports local loads with PV, battery, and inverter coordination.
• Lower Grid Dependence
  Helps them rely more on self-generated solar energy.
• Reliable Power Support
  Provides stored energy when solar output is unavailable.
• Suitable for Island and Remote Sites
  Works well for areas where grid power is limited and unstable.
