This vertical axis solar tracker needs an external power supply and the input voltage is 380VAC (three-phase four limits), the output voltage being 380VAC. The vertical axis automatic solar tracker does not require additional components and has a large power generation input to meet the operation of larger power AC motors. It has multiple protections to enhance system stability. Passing more than 20 internal tests (UV, thermal cycle, wet cooling), internal tests are stricter than the industry certification standards.
