this is the only way to go, a must have for a solar charging system

Product is good, purchased this o b e to slit my system into 2 separate voltage

Fantastic product, absolutely worth the money if you have a large array, or like me, limited roof space (camper van) and need to suck every last watt out of your panels while accurately monitoring (especially if you get the whizbang as well) every little detail.

Compare all the big companies out there and "Midnight Solar" not only sells the most powerful 48 - 72 volt charge controller.
They also make some of the most unique features found in a Wi-Fi enabled charge controller.

It data logs everything for 4 straight months, is ridiculously efficient. Has every safety a security feature on the market, including a few unique to it's chip set. Plus it's the only unit more powerful than Australia's and it has features exclusive to Midnight Solar's products. If you really want to be impressed, do a Google search on every currently available charge controller in it's power range. Then compare their features in both program-ability and data logging. Imagine coming back from a drive to find that your charge controller didn't catch a voltage irregularity and your batteries were damaged by the 5 kilowatt current it hammered them with....

Or in this units case, you set up all the levels and safety margins yourself. What's more you can check on the units current status from your Droid any time as well as anything it's data logged that your filters have flagged time stamped and up for analysis. It's an awesome unit and It's got a great warranty too. This is a lot like the Solar World panels in terms of being time tested for well over a decade and still at the top of the Leader Boards. ^_^

Very versatile. Able to easily adjust charging points to exactly what the battery manufacturer recommends. Also the highest amperage controller I found on the market.
