Single Panel MICRO-Inverter JST-YC250
The Just Solar Micro-Inverter is individually connected to one, two or three PV-modules and converts the direct current (DC) into grid compliant alternating current (AC). Micro-inverters connected PV-modules are able to work independently at their maximum capability.
