Hypery battery review 3 months on. Unfortunately I lost nearly all of my test footage but promise to do another test soon. For now however here are my quick thoughts.
I just saw this. I have my system set up with twenty batteries from Autozone. They're not the same batteries as yours, but I noticed when my freezer comes on, it takes an initial shot of power to start the compressor, that seems to be more than it should be. When I first got the freezer, I had sixteen batteries, and what I have noticed, as I added batteries, this initial surge effects a smaller voltage drop now. What happens is, each battery can only deliver so many amps. So when the load comes on, the voltage drops at the battery side of the inverter too much if there's not multiple batteries. It's just more noticeable with the cheaper batteries like I have. What is probably happening to yours is the voltage drops momentarily, so the voltage coming out of the inverter drops too. The two things I would try are some kind of big capacitors to keep the voltage up until the compressor has time to get running, and you should have a Kill A Watt meter to tell you what the voltages and wattages are starting and running. I used a 24 volts hookup to help with the amps, which can be pretty high on startup of electric motors. I started with cheap marine batteries which are not really optimum for solar, but as they go bad, Im changing them out with heavier amp hour true deep cycle batteries. I have four of those now. As long as I keep twenty of them, they work pretty well. I had to replace one about five days ago. It was one of the first ones I bought. I had four batteries and three solar panels. Ever since I changed it out, the voltage has been higher at the end of the day. So it was probably damaged a long time ago. I bought snaller amp hours batteries at first. They were eighty five amp hours. The ones Im replacing with are 105 ah. Right now I have a thousand amp hours of battery bank. When all the smaller ones are changed out, there will be 1120 ah. When my freezer comes on, theres a barely noticeable blink of the lights, where if there's not enough start up amps, it will be a lot more noticeable and longer blinking of the lights. By the time it starts to blink, the freezer is already running. I would have and maybe should have gotten better batteries at the start, but I was trying to save up enough for an inverter charger. It's almost six a.m., and battery bank voltage ⚡ is 25.18. They'll be charging again in ninety minutes. Everyone's systems are different. Don't be surprised if you need more batteries though, to get the desired results. I used to wonder why owner's manuals for an inverter would show it being hooked up to eight batteries. My freezer just came on, the voltage dropped eleven hundreths of a volt. The refrigerator came on too, another nine hundreths.
Hi, thanks for uploading the information about this battery (I think you now have the only 2 reviews on the entire web) lol. Hope the battery will serve you well :-)
