Auxiliary Output for Dual Battery Charge or 20A LVD Load Output : Patio, Lawn & Garden Review: Blue Sky is the best MPPT controller at this great desertcart price!!! - A very good company. A very good product (for small to midsize solar installs). And since this is my 2nd add-on controller, a very good system to employ for my solar needs on my RV... To top it off, Blue Sky Energy sets the industry standard for customer service and backing their products quality and technical service!!! I have delt with Morningstar previously, and they don't hold a candle to BSE--when I called MStar, they told me they would need to charge me to answer any technical related questions/issues...that killed that relationship in a hurry!!! Review: Works great, good design - It works well. Pretty much nothing else to say. Installing this is not trivial, you need to understand how and why things are done and follow the manual exactly. It isn't hard IF you know something about 12 volt systems and electronics. Another review says a couple of things that are NOT TRUE. * The unit is designed with a standard interior steel electrical box. Not "cheap", just not weatherproof. * Even in a boat or RV it _still_ needs to have the case grounded. If you don't understand how/why this is you should have it installed by a professional. * The box has standard panel knockouts for wiring. You NEED to use conduit, or cable clamps like _the manual says_. If you don't know this, you should have it installed by a professional. * Look at the manual online at Blue Sky's website. If you do not understand every part of it, have it installed by a professional. * If you need to use 4AWG wire from your panels they will work just fine. * If you have a problem with the program chip you CAN replace it yourself. Blue Sky will send you an upgrade for free. It takes two minutes. ## Features - MPPT BUCK charge controller 12/24V battery.

After looking around on my own, I kicked various ideas around with the tech support folks, and simply ordered a second one. They helped me connect the two together to double the power of the system. The original controller has been hard at work for almost three years. This was more cost effective than junking the original system and getting a larger controller. ## Frequently Bought Together - Blue Sky Energy Solar Boost SB3024iL MPPT Charge Controller 40A/30A, 12V/24V Battery.
