Charge controller recommendations

I have a small solar charging system consisting of two 12v 75w panels wired in series and a failing cheap MPPT charge controller. I may be acquiring another identical panel too. I'm currently leaning toward the Morningstar 15 Amp MPPT model. I looked at that Eco-worthy model that several forum members purchased, but am now a bit gun shy about off brands. I don't think it could handle a third panel in series either. Bluesky doesn't appear to offer anything that fits my system at a reasonable price point. I couldn't tell what Rogue had available.

I also seem to remember that my panels can be configured for 6v operation which may open the door to some of those marginal controllers.

Any thoughts or recommendations?

    New Rogue was expected to arrive about this time, but I am not sure they have it yet. With the previous model sold out, they don't have those either. The last update says that new circuit board has arrived, so they must be doing some testing, so it's probably a few weeks or more until the first unit is up for sale.

    I am waiting for Rogue. But, you don't have to. With 5A current of 2 small panels in series, Rogue $300+ is overkill. Wire them in parallel and get 15A PWM controller for a fraction of cost.

    Third season with my Rogue, with no problems at all! They have a new version of it out. Call there, and talk to Mark. He's incredibly helpful!
