A station fits when this panel's 48 V open-circuit voltage sits inside the station's published solar window and the plug matches. MC4 panels connect to any station through a standard MC4 adapter cable. Recharge time is from empty in full sun, using 300 W (75% of the rating) or the station's input limit, whichever is lower. 3 of these stations don't publish a maximum solar voltage, so check the manual before connecting.
