select the number of solar panels and links, in accordance with the requirements of the controller to select the necessary functions, in accordance with the monitoring requirements to see whether the need for ammeter and Voltmeter.
Generally only assembled solar charger, buy devices, assembly, commissioning, use. Buy the device, but also constitute the solar panels, the controller, according to your output requirements,
