Hi..been a lurker and read loads of great stuff. Thanks!
My dilemma....have ordered new Expanda with solar on roof. Sorts out a problem we've had for years and have been mucking around with portable solar for ages so reasonably conversant with all that.
We also want to be able to use 120w portable panels to supplement installed roof panels (via anderson plug direct to battery and with separate solar mppt controller) to maximise solar gain if camped in shade. Have had conflicting advice as to best way to do this.
Has anyone done this? If so, what was the effect on battery charge? Did battery try to equalise solar input from two separate solar sources. Not parallel but totally separate.
One auto electrician is iffy and another is sure it will work. We like to br self sufficient for as long as possible, given usual water supply restriction and can and have managed to be off grid for up to a month .... but not while totally dependent on roof panels only.
Any thoughts / experiences appreciated.
