Hey all,
A couple of weeks ago I finally finished setting up and turning on my system with 12x 100w panels.
( thread here: https://diysolarforum.com/threads/finally-turned-on.22094/ )
It wasn't charging up my batteries as well as I expected, which I figured was probably due to the generic charge controller. At best it seemed to be producing about 800-900W.
Since the panels are all Rich Solar, I went ahead and picked up the Rich Solar 40A MPPT w/ BT. (apparently it's the same as the Renogy model)
I installed it yesterday. To my surprise, it was peaking at just over 1100W today. (the highest I saw it hit was 1135W)
Then I saw that it was triggering a "PV Overload" error each time it nudged above 1100W. My old (and apparently inefficient) MPPT was rated up to 1560W.
It's not shutting down or hurting the rest of my system, but I'm wondering if there's a likely risk of damaging the unit (or burning down my house). Documentation's hard to find (and the BT app isn't that great either).
At one point in my research I came across a random post (for the Renogy model) that mentioned it might shut down at 1.05x the rating (1155W) and need to be reset, so that's a little concerning.
If it's doing over 1100W now, I expect it'll have no problem hitting 1200W over the summer. I really didn't expect it to operate that efficiently and thought there'd be more of a loss since the MPPT is 50ft from the panels.
I'm considering sending it back and getting an EPEVER rated for 1200W instead (max 1560W).
It doesn't have the BT module, but that's not really a loss.
What do you think?
Looking forward to your feedback. Thanks!
