Just wanted to up the start rating on this product since Tyson thought he was doing altE justice by putting a negative review on a specific product. Unfortunately, the product was designed, built, and sold by a gentlemen named Ralph Hiesey in Boulder Creek, CA. We've been using the SC-2030 PWM Charge Controller for 3 years and couldn't be happier. We feel the bigger your solar bank the better the value. Still, even with a single battery in your bank, the price makes it the best option for most people. Pair this with Ralph's volt/amp meter and you are sure to be quite happy!
The real selling point is Ralph's customer service. If you buy this product, do not call AltE regarding this produce, call Bogart Engineering and talk to the guy you designed and built the device. Ralph is just a pleasure to talk with and seems to really care about you and your system.
Truth be told, I have never ordered from AltE. For what is worth, I have visited company headquarters and was well-received, despite being mostly an online store.
