Steca PLI

300, 300-L60


The Steca PLI-300 is a cost-effective 300 W sine wave inverter that can be used to operate small AC loads. It has a manual on/off switch that can be used to switch the inverter off, avoiding self-consumption. The unit is particularly suitable for solar home systems in which small AC loads are manually switched on as required in addition to the DC loads. The unit is supplied with DC cables and has a European AC connection socket.
