HBOWA supplied a 100kW / 500kWh energy storage system for a solar self-consumption project in Bohol, Philippines. The system uses two 50kW Deye hybrid inverters together with 500kWh battery storage, helping the customer improve solar energy utilization and maintain a stable local power supply on the island.

Project Overview

Customer Challenge

The customer needed a stable and efficient energy solution for island power use. In island areas, electricity supply can be less stable, and solar power without storage cannot fully cover power demand during evening hours or low-generation periods. He wanted to improve solar self-consumption and reduce reliance on external power sources.

Energy Storage Solution

HBOWA provided a 100kW / 500kWh battery energy storage system with two 50kW Deye hybrid inverters connected in parallel, and 500kwh high voltage battery in racks.

The system supports:

• Direct solar self-consumption
• Battery storage of excess daytime solar power
• Power supply during nighttime or low-solar periods
• Stable load support for island applications
• Intelligent coordination between PV, battery, and load

Project Benefits

• Higher Solar Utilization
  Stores excess solar power in 500kwh battery for later use.
• Stable Island Power Supply
  Supports daily electricity demand with battery backup.
• Lower Dependence on External Power
  Improves local energy self-sufficiency as a power backup system.
• Flexible Hybrid Operation
  Two 50kW Deye hybrid inverters provide stable system operation.
• Suitable for Island Applications
  Works well for self-use power systems in the island locations.
