Works as advertised! Great deal, charges, even in low light, stormy conditions,
The charge controller works, the buttons are kinda particular.
The only thing I don't like, ( but for the price ) the charge controler has lots of custom features- however does not show the voltage coming from the panels. Just the battery voltage. You can also see, discharge,charge settings. The only reason it did not get 5 stars.
But the settings are customizable.
