PWM charge controller doesn't have a fixed max. PV power limit. But the Voc of the PV array needs to be lower than the max. Voc of the controller and the Isc of PV array need to be lower than the rated charge current of controller.
LS-B Series(10A~30A) PWM Charge Controller
LS-B Series(10A~30A) PWM Charge Controller
With RS485 interface and optional remote meter.
Where to buy
LandStar-B series is a common positive PWM charge controller. Thanks to the RS485 interface. The parameters can be configured via com. Port, APP, and PC software. It is widely applied to solar home systems, and surveillance system, etc.,
