« Load, or »Low Voltage Disconnect" output

Some solar controllers have a « LOAD », or LVD output, which can be used for smaller loads, such as small appliances and lights. The advantage is that the load terminals have a low voltage disconnect, so it will turn off whatever is connected to the load terminals and keep from running the battery down too far. The LOAD output is often used for small non-critical loads, such as lights. Some solar controllers also can be used as a lighting controller, to turn lights on at dark. Do not use the LOAD output to run inverters bevause inverters can have very high surge currents and may blow the controller.

Most systems do not need the LVD function - it can drive only smaller loads. Depending on the rating of the controller, this may be from 6 to 60 amps. You cannot run any but the smallest inverter from the LOAD output. On some controllers, such as the Morningstar SS series, the load output can be used to drive a heavy duty relay for load control, gen start etc. The LOAD or LVD output is most often used in remote systems, such as camera, monitor, and cell phone sites where the load is small and the site is unattended.

All of wellsee solar controllers have LVD voltage"
