Review: Solid, Works Great, Wish It Could Take in Higher Voltage - Used this to replace a non-MPPT charge controller so that I could get more power out of a 100W panel. What I would REALLY want is two 100W panels in series (not parallel so that one shaded doesn't affect the other) and then use the MPPT to optimize, but the flexible panels I am using on an RV are 20-22V OCV, and that exceeds their recommended max input. Hopefully the next version will take in up to, say, 60VDC OCV. But still five stars because it never claimed to do that, and is solid and performs as expected.
Review: Awesome product - So far I love this product. I only bought it because it fits my old flush mount controller cut out and for the customizable charge profiles and temperature compensation for my Firefly carbon foam batteries and didn’t think I would see a big boost in charging amperage. I see a BIG boost in charging amperage. Like 30% plus across the board from my old PWM go power controller. Under the best conditions with my old controller I saw around 8 amps. It is not uncommon now to be charging above 12. Awesome product

### ⭐⭐⭐⭐⭐ Amazing product
*by S***N on September 15, 2020*

I was first introduced to this product by my Grandfather. If your like me Grandparents are wise and really know what’s best. I purchased a new RV and the dealer installed 400 watts of solar and a cheap go power charger. I was within the first few uses and realized i needed a better controller. I have had several of the 3000I controllers and after changing this out I can tell you there was a major difference. The product easily gets a 5 star rating. I have on several Instances called the manufacturer to get help designing different systems. The knowledge and willingness to help has been over the top amazing. The customer service I have received from them is way more than 5 stars. Amazing company and great products.
