Howdy folks, I am a beginning Solar Power harvester with two 100 watt panels to charge my Vmax 100 Amp/Hour AGM battery which is then used via an inverter to power a 100 watt twin mattress heating pad. I have unplugged my central heating system and this has produced huge savings in my utility bill. The problem is on some nights, especially when the wife goes to sleep early, by the time the morning comes the battery has fallen well below the 50 percent (12.3 Volt) level and sometimes so low that the inverter beeps a warning. This is bad ju ju for my battery lifespan. I know that buying another battery would help but my current solar harvesting ability will only support charging one 100 Amp/Hour Battery on a good day, and I also know that increasing the number of panels will also help. But what I really want is an inverter that plugs into the AC outlet and the battery and when the batteries drop below a predetermined voltage threshold, the inverter will automatically switch to AC power and save my poor batteries. I have found transfer switch inverters but those are designed by default to switch over to AC when it senses the presence of AC and that is great for emergency back up when you lose power. But I want to use the batteries even when there is AC available and only use the AC when the batteries fall below a certain voltage level. I have relied on my ability to check on the system when I wake up at night to use the bathroom and if I see the battery has dropped to near 12.3 volts, I manually move the plug over to an outlet.
Do any of you folks know of an inverter that will do this for me?
