Solaris / A30 controller

Digital display DC voltage detection, control the relay output. Can be used to cut power off for low voltage protection and/or used to power for solar input.

DC 6~80V relay interface board with 2 buttons for easy operation.
With clear LED display, convenient to check the value.
Adjustable Voltage Detection Range: DC 0~99.9V.
When the measured voltage is lower than the lower limit or higher than upper limit value, the relay works.
Can be used for voltage detection switch, battery over/under voltage protector or discharge meter.
Comes with a cover for protection.

Can be used in conjunction with a higher output relay to be used for powering our water heaters as A30 is not rated more than 10A
