I went a more expensive route but never regretted it as I want a stable power supply for my SunFrost and 12V DC Pumps. I have an Iota AC to 12v DC charger/power supply which works with or without batteries. I have kept a 12V battery attached as it gives me 2nd level redundancy when my main bank hits low battery cutoff.... the DC equipment starts with a full battery. My 48V Outback is on all the time anyway and the small AC to DC loss is insignificant it my system and also when I monitor the outback system with Optics, I see all my loads, including the 12V DC Loads as one measurement. I have been using this system for about 10 years with no problems. Most of the time the Iota is just coasting but if I need surge capacity, it can handle 30 amps. Also I left my 12V system in tack so I have some DC lights and anything else I want to plug into 12v (ie, charging a car battery, 12V laptop power cord) it is available. My 2 L16 batteries on the system are vurtually dead right now, probably no water in them, but the surface charge works with the Iota and no negative affects.
