Package solar power generation, storage batteries, and EV charging systems! Maximize the use of solar power to minimize CO2 emissions and electricity costs!

■Maximize the use of electricity generated by solar power through packaging! Even when solar power generation is introduced, there are often cases where the expected reduction in CO2 emissions does not materialize due to the generation of surplus electricity (waste) from not using storage batteries and the peak in electricity demand caused by concentrated EV charging. The self-consumption package combines solar power generation equipment, storage batteries, EV charging systems, etc., all equipped with our unique control technology "Synergy Link." This allows for the full utilization of solar power generation electricity and can increase CO2 reduction by up to 50%*. *Compared to typical usage conditions without EMS. ■Optimal proposals tailored to your facility's situation and requests! When introducing the self-consumption package, we conduct a unique pre-simulation to estimate the amount of electricity that can be generated by solar power and the capacity of storage batteries that can effectively utilize surplus electricity generated on holidays. This enables us to propose the most suitable equipment based on your facility's situation and requests. ■Easy to introduce self-consumption solar power generation and expand equipment! By introducing the package, individual equipment selection and complex design become unnecessary, making it easy to expand or replace equipment and reduce costs associated with system modifications. This allows for flexible responses to future decarbonization efforts.

Reuse of used EV batteries as industrial storage batteries! "Reuse Battery Package" for self-consumption solar power generation.

■Cost reduction through the reuse of used EV batteries Compared to industrial storage batteries using new batteries, the introduction cost is reduced by about 30%. Additionally, it becomes possible to change the cooling equipment to fans that utilize the characteristics of used batteries, resulting in a 90% reduction in running costs. Furthermore, we use used batteries from Nissan's "Leaf," provided by 4R Energy, which are known for their reliability and durability, ensuring sufficient performance for industrial storage batteries intended for self-consumption. ■Significant contribution to environmental considerations By using used batteries, CO2 emissions generated during the manufacturing of new batteries are eliminated, contributing to decarbonization. Moreover, the reuse of rare metal resources also addresses resource depletion issues. (This falls under the customer's Scope 3 "Category 1.") Our unique control technology, "Synergy Link," enables easy and low-cost integration with existing facilities and other solar power generation systems, as well as system expansion. *We can propose either new or reused options according to the facility environment and customer requirements.
