HID AUSTRALIA PTY LTDENERGY SOLUTIONS

HIGH CAPACITY HYBRID POWER SYSTEMFOR EFFICIENT USE OF RENEWABLE ENERGY

enerstore

The enerstore 7000 provides a CONSTANT POWER SYSTEM by combining PV Power, Wind Power and energy storage to substitute diesel generated energy

PV power can be directly connected to the DC bus via an intelligent string booster box

This turnkey energy solution comes with Switchgear, Medium Voltage Transformer, Battery Charger and Inverter, Load Management System and up to 368 HITACHI AVRLA Battery Cells 1500 Ah.

The enerstore container is constructed for any field installation and is able to provide areas with continuous and independent energy. It is designed to operate in combination with PV Systems, Wind Turbines and Diesel Generators for Smart Grid as well as Off Grid Solutions.

Performance Diagram

The energy storage system can be completely discharged (SOC = 30%) with a power of 100 kW. If by extracting higher power the discharge limit is reached, the remaining energy can be extracted by reducing the discharge power.

Grid connected charging

Maximum charging by PV power

Every 14 days the system will perform an equalizing charge which will take approx. 12 hours.

The cycle life of 4,500 complete cycles (DOD 100% - 30% - 100%) is specified at a charging power of 115 kW max. This is equivalent to a charging current of 150 A. Under this charging method the system can be completely charged within 10 hours maximum.

The charging method generally is depending on the application. We basically distinguish between grid connected systems and PV Hybrid systems used in Off Grid systems.

For grid connected systems we apply multistep charging according to the below diagram. Charging time under this method is about 6 hours.

For island / off grid systems we apply a simple U/I curve in order to absorb a maximum of available energy. Maximum charging power under this method is 270 kW. Provided that there is sufficient energy available the system can be fully charged within less than 4 hours.
