Rogue MPT-3048 now available

Well, that sucks.

no more mpt-3048

Other news: After a lot of deliberating, we've decided not to produce another run of the MPT-3048. The niche for a 30A MPPT controller is no longer what it was when Rogue first came out with one. We were one of about two companies in 2008 that sold a fully programmable 30A MPPT controller. Now there are at least three US-based companies and a handful of Chinese competition that have crowded the market, such that we can no longer economically manufacture the 3048. The MPT-2024 may also be discontinued after existing stock runs out, for the same reason (it is actually much less profitable than the 3048 is). We have a good supply of the 2024 right now, but will likely sell out this year. The flip side of all of this is that we have some ideas for designs that are presently not being produced by any manufacturer, and which have a strong potential to create a new niche for a smaller company like Rogue. Stay tuned this year for more details on what's to come!

Thanks
I understand things take time and there are other higher priorities
Looking forward to reading the document when it becomes available

Yes, it will be published. I've had others ask as well, just haven't had the time yet to document it properly.

1. You define efficiency at a particular input and output voltage. What's missing is current.

I'm not knocking your actual efficiencies. They're great. It's just that the way it's presented is misleading.

2. The voltage and current measurement error spec is unconventional and useless. The displayed V & I measurements have significant errors. We went through this once before. The calculated output power was greater than the calculated input power. We know that's impossible.

Sal, if you have any genuine critiques or questions, I'd be happy to entertain them. Nitpicking about non-issues doesn't qualify.

Nice looking new unit

A few questions

Good to see you mentioned the availablity of Multi-Phased units
At 30amps it likely adds too much additional cost with limited return, however anything above 30 amps multi-phased units do indeed offer efficiency increases throughout their operating current ranges.

From my POV the meter accuracy discussion is a non-issue so long as the meter reading is repeatable, which I assume it is

He does: this one. Posted a review a while ago, on FB and here.

As noted, this is a new model, released a week ago after testing. Previous model 3024 had good reviews. With manufacturer being local, I don't expect much hassle with warranty - you won't have to ship it to China.

Assuming it is adequate for your system size and voltage - I don't see anything better at that price. The closest is MS45 with 50% more amps, 40% more money (if all same features are added), and blinking lights on the main unit. Or Bluesky 30 - same amps as Rogue, don't know about accuracy ;), and also more money.

I don't own one but their customers like it. At least that's what I have read (in other forums....not sure who owns one here). BTW, this one is a brand new model so probably not too many reviews yet. I was talking about their old one.

Mena, this has been going on for months if not years. Salvo just doesn't like the Rogue guy. The Rogue guy knows it. Gets old. :(

Salvo has been taking his civilization pills for quite some time now, and has been very helpful on a number of topics. I am especially grateful for some help in particular.

No idea why the Rogue guy gets up Salvo's nose. Just glad it's not me anymore with my "measurement errors." :)

Ok. Didn't know about the history. Thanks.
