Seems to indicate as such, it can both check for unused power using a couple of CT clamps and be scheduled to charge overnight.Apologies if I am not quite with your reply, my object is to install a battery to harvest any unused power by my panels and import from the grid during the early hours of the morning, is this system not suitable for this. Thank you in advance.
Incidentally, you don’t even need a spark to set these up - they just have to be the one to finalise connecting it to your supply.
Not sure how quickly they’d pay off mind you
