Who wants to talk battery backup systems? Inverter/chargers and big batteries. There are other old threads out there on this topic but much of the specific equipment linked is obsolete. This equipment costs big bucks so it needs to be correct the first time. Other member's experience with specific equipment would be priceless!
I am researching a system for powering an AC return pump, a small backup heater, and preferably also a DC wavemaker powerhead. I know it is redundant to run a DC pump off AC power on an inverter. But for simplicities sake it would be nice to run all required equipment off one unit.
Inverter/Charger Selection - Pure Sine vs Modified Sine?
The Tripp Lite APS 750 appears to be a popular unit. It produces modified sine wave power. Does anyone have experience with this specific model? Is the power clean enough to run AC pumps and DC pumps with variable speed controllers? And with the cheaper pure sine inverters like the ones linked below, are you really getting a quality product? Another consideration with these inverter/chargers appears to be AC power draw while charging the battery. After a power outage, when the utility power returns, you have essentially added a large battery charger to the house circuit along with your tank. Can you main breaker handle it? Some of the inverters appear to have power draw adjustments for this and others do not.

Battery Selection - It appears that the only real choice for a system like this is AGM batteries. Flooded cell batteries can not only emit hydrogen gas, but the risk of spilling acid/lead inside your house is too great. According to my research AGM appears to be far safer. The 200Ah class batteries have caught my eye, for around $400. Anything less just doesn't seem enough.

Does anyone have experience with specific products to accomplish these goals, and equipment that did or did not work with such a system?
Thanks!
