I've always feared power outages. I've tried to think of the best method to keep the temperature and water movement flowing through the whole system, (tank and sump). With the controller systems I have found that there isn't any where to plug in a reserve UPS to power certain items. Therefore I made the decision to run without a controller and instead plug the return pump and one of the heaters to the biggest UPS I could find at memory express. I know this is not a viable solution for long outages or bigger tanks. According to my UPS I have only 80 minutes of run time which is not very much, my pump is the smallest DC Speedwave and my heater is only 100watts. I've always thought about running the inverter in my truck if worse comes to worse and we have a long power outage, however I am unsure of how clean the sin waves will be.
