I like it a lot. They have great tech support. I originally didn't care to much about the extra features of the Midnite, but now that I have them, it's worth it. It also saved me from feeling like a battery monitor was necessary which saved me about $180. I haven't been able to get batteries below 80% yet and I run the hot water heater (2000 watt element) for 45 mins a day which is all it takes to get 20 gallons up to temp and it holds all day. I end almost every day with 99%-100% full batteries and wake up with them at 94-96%. I wake up, run the hot water heater for 45 mins, take a shower, and then shut it off. By now the batteries are at about 87% or so between the overnight usage by the fridge and the hot water heating of the morning. The batteries are charged again by sometime in the early afternoon, depending on the sun. We haven't had a long streak of cloudy days since I got my system running, and we'll see how winter goes, but I still have another 300 watt panel I will be bringing to the system once I figure out a better way to keep the 12v system charged. I was skeptical about using an electric water heater, but so far it is working out really really well to my surprise. I was planning on using a separate solar hot water system as the primary hot water heat source, but now, it doesn't look like that will be needed. If is still needed more hot water or electricity, I could easily add another 2 300 watt panels to my rack and combiner box for a total of 1800 watts of solar panels. The cool thing is that, at this point, I can increase my power generation by 50% and it would only cost me $450 (10% of the pv investment so far). The controller, batteries, etc. al are already more than capable to handle it. I estimate I would be making around 7kwh on a good day, with 12kwh in storage. I mean, in 1 day, I could use 15kwh, and still have 33% of my battery remaining for the night...wake up and have 25%, then have it charged back to full in 2 or so days... Some would say that that only makes sense if I have a bigger battery bank. But the way I see it, I'll be making great energy even on cloudy days which means that, save a nuclear winter, the number of viable days I have for charging my batteries will be HUGE. It could be a cloudy day in december and I'll still cop a great charge. I want to be able to weld, use my power tools, compressor, etc... we will have to see once I get a new project going. I love electricity and would love to ditch the propane stove someday--it's the only fossil-fueled/manufactured energy source I can't work around in a way i like..yet..
