Rogue 20A MPPT Controller Question

300w and 20a controller will serve you well.

If you expand in the future... cross that bridge when you get to it. It might be a second 20a controller or a replacement 60a controller. Might be higher open circuit voltage MPPT needed or high amp PWM depending. Expansion system may not series or parallel well with existing panels. Too many future what ifs. Load that 20a with 300w and enjoy.

Good points smk! I just might need more than 10A for expansion next go round and a second controller may just make more sense. And it will save me $100 towards panels.

I was thinking cheaper MPPT too like the Tracer if you don't want all the fancy data stuff and laptop connections etc which have nothing to do with feeding the batteries but do provide geek entertainment :)

A 20a, 100Voc Tracer is about $140

You know I didn't think I wanted all the fanciness but at $275 for the Rogue 20A, it's not too much considering what you get plus Marc is really helpful here. I'd like to support his company. Plus I worry about the cheaper units shutting off in the summer like the Iota converters do.
