Good product at good price. No fan to break, or get dirty.
Just make sure you can live with the positive being common ground, i.e. you need to ground the positive terminal if you need to ground the controller.
Get also the remote MT-5, it makes it much easier to program and use.
worked great right out of the box. With this I can expand my system in the future.
Best money can Buy!
I love this charge controller, it's been working beautifully in my rv for a year now. I have three 300 watt @ 36 volt panels wired in parallel connected to the 40 amp version (900 watts), which, if you read the manual, is well within the specs. I think the max is 1500 watts. The most it'll ever output is 40 amps though. And since my panels are flat mounted I very rarely reach that max, oh well.
If you go high power like this make sure to wire in parallel, since it has a maximum voltage of 100 volts. That's a big limitation compared to more expensive controllers like the Morningstar mppt45, which is 150 volts. No biggie for an rv with 60 or 72 cell panels though, since they're already high voltage so wiring them in parallel still gets the benefit of mppt, and the wiring run has to be short on an rv.
Anyway, awesome charge controller, highly recommended.
