Effective use of generated power with patented power generation control and storage battery recharge/discharge control
Solar Legato Battery realizes effective use of generated power through patented power generation control and storage battery charge/discharge control.
1.Effective use of generated power with patented power generation control and storage battery recharge/discharge control
2.Control system, remote monitoring, and PR content are provided as a set.
Patented technology maximizes power generation
Optimal control of the entire facility
Unlike control by storage battery-integrated inverters, the control system is independent, enabling optimal energy management based on a comprehensive assessment of the respective status of power generation and storage.In particular, it has the advantage of being able to flexibly adapt to future changes in systems and mechanisms, and it also looks ahead to smart energy systems of the future.
Output command values are calculated based on the relationship between power generation, power consumption, and storage battery free capacity. Control commands are issued to storage batteries and inverters.
Storage Battery Control
Enables control of recharge/discharge of storage batteries for optimal control of the entire system. Supports operation with less power purchase and enables more effective use of generated power.
When Solar Legato Battery is installed in a system including storage batteries
Optimal power generation is performed by controlling the output command value (%) calculated from the relationship between power generated, power consumed, and storage battery empty capacity.
When recharging storage batteries
Based on the calculated rechargeable power, the maximum output power is determined, and the inverter is commanded to generate power and the storage batteries are commanded to recharge, respectively.
When storage battery is discharged
Based on the calculated dischargeable power, the maximum output power is determined, and the inverter is commanded to generate power and the storage batteries are commanded to discharge power, respectively.
Control Parameter Setting Screen
Priority charging function
Specify a time period and command the storage batteries to charge the generated power regardless of power consumption or power generation.
Priority discharge function
Specify a time period or threshold value and command the storage batteries to forcibly discharge.
Residual volume maintenance function
The minimum remaining capacity of the storage battery is specified in %, and recharge/discharge control is performed to the extent that it does not fall below this level.

Advantages of introducing storage batteries
Efficiency of self-consumption photovoltaic power generation
When used in conjunction with storage batteries, power generated in excess of power consumption can be stored for more efficient operation.
Peak cut
Storage batteries are used to reduce electricity use during times of high power usage, saving energy and reducing electricity costs.
Subsidies available
Subsidies offered by ministries and local governments can be utilized, and the cost of installing equipment can be reduced.
