Charge and Discharge Controllers


PWM + Original Technologies
Batteries are charged optimally by using solar generated power as a result of PWM and our own technologies.
Automatic Battery Voltage Selection
The battery voltage (12 V/24 V) is selected automatically.
* Use a sealed lead-acid battery.
Supported PV Modules
When the rated input voltage is 70 V and the current is 10 A/20 A or less, monocrystalline, multicrystalline, and CIS (CISG) PV modules can be used.
* The operation of other PV modules is not guaranteed. Please contact us.
Built-in Test Mode
In test mode, the operation is performed with the timer setting of 1 hour shortened to 6 seconds.
Voltage Setting for Adjusting Load Timing at Sundown
It is possible to configure a load output starting time according to the installation location. (Dusk-to-dawn/for a few hours to several hours) (15 types can be set.)
Protection Function
The product is protected by over-charge, over-discharge, and backward current protection circuits and burnout prevention fuse.
DC Inputs
Batteries can be charged by connecting a switching power supply.
* The operation of power supplies other than the recommended ones is not guaranteed.
Outputs for 16 Types
The built-in microcomputer has 16 types of the output settings.
Two types (output duty) of light adjustment function (25%/50%) are provided.
