GS Yuasa Launches Power Solar III, a Power Conditioner for Solar Power Generation Integrated with Lithium-Ion Batteries
GS Yuasa Corporation (Tokyo Stock Exchange: 6674; “GS Yuasa”) announced today that it has launched a power conditioner for solar power generation integrated with lithium-ion batteries that is optimal for use in creating disaster-resistant areas with low environmental impact and reducing energy costs.
The use of solar power generation systems for both residential and industrial applications has become widespread following the July 2012 introduction of the Feed-in Tariff System for Renewable Energy. Currently, public interest in and needs for the construction of stand-alone distributed energy supply systems and peak control of electricity supply and demand are increasing.
The newly launched Power Solar III, equipped with a power conditioner with output capacity of 4.5 kWand LIM50 series lithium-ion batteries, makes possible the stable supply of electric power even during major power outages caused by natural disasters. In addition, charging the storage batteries with late-night power or power generated from sunlight makes it possible to supplement power supply with power from the storage batteries on cloudy days or at other times when solar power is low.
GS Yuasa will continue to meet diverse needs for the strengthening of disaster response facility functions and the effective utilization of renewable energy by disseminating Power Solar III and other power storage systems.
1. Integrated structure consisting of a power conditioner ＋ lithium-ion batteries
At the time of purchase, users can select from three types with lithium-ion battery capacity of 4.2 kWh, 8.4 kWh, or 12.6 kWh.
2. Outdoor installation possible
Use of a stand-alone cabinet with IP34-equivalent1 dust and water ingress protection makes possible outdoor installation.
3. No need for the backflow prevention relay normally required for systems with storage batteries
A GS Yuasa original patented technology prevents reverse power flow2 from the storage batteries, making possible reverse power flow from photovoltaic panels.
4. Use of a touch panel monitor
User operations such as setting of manual/automatic switching to stand-alone operation are simple.
5. Three selectable operation modes
The system is equipped with Power Outage Operation Mode, which is suitable for disaster prevention applications, Late-Night Power Use Operation Mode, and Solar Cell Power Charging Operation Mode, which can be set using a touch panel monitor.
1 The IP Code is a standard that indicates classifications of protection against dust and water. IP34 indicates a level of protection against ingress of objects 2.5 mm or greater in diameter and no harmful effect from water splashing against the enclosure from any direction.
2 Reverse power flow is the flow of active power toward a commercial power system from solar power generation systems and other distributed power sources.
100 systems in the first year
