The "Solar Control Box TYPE9.12LC" has been upgraded to a Pro version with the addition of an internal state monitoring function.

We are launching a new series from the Solar Control Box! While maintaining the advantages of the previous model, such as its compact size, we have added a "monitoring function" that allows you to immediately check internal conditions such as voltage and current input/output values, battery level, and load capacity. By changing the measuring instrument from analog to digital, it has become easier to quickly verify accurate numerical values, which helps reduce human errors caused by misreading or misinterpretation of the numbers. This product series can be fully customized according to your usage needs and requests. We can accommodate requests such as wanting a color that does not disrupt the landscape or setting output values, so please inquire through the custom form on our website. 【 Free Catalog Available! 】 Examples of systems, external dimensions, and other detailed electrical characteristics are listed on the back of the catalog. Since it is in a flyer format, it is easy to read, so please feel free to download and check the catalog on our website or within Ipros.
