    Odd battery behavior

    I have 8 new Duracel GC2 230ah batteries and have similar results. I have 2,000 watts of solar panels connected. Batteries are fully recharged by noon with 28.8v and float charged for the rest of the day. Once night time with no solar, voltage is at 25.7v. Drawing 400w for a few minutes drops...

    Do I need a DIY Low Battery Disconnect, or buy one for my situation

    I was going to buy the $200 victron battery monitor but the reviews on this site gave good reviews for the $50 battery monitor so i went with that. Big mistake because this monitor cannot keep track with the charging and discharging on my battery bank. Perhaps i might buy the Victron battery...

    Do I need a DIY Low Battery Disconnect, or buy one for my situation

    My Kill A Watt meter is pretty accurate and my 120v well pump only draw 300 to 400 watts from inverter or gas powered generator. As for my connections, all DC cables less than 5 feet from Inverter, batteries, charge controllers. 2 guage cables. My batteries are craps and I wished I had bought...

    Do I need a DIY Low Battery Disconnect, or buy one for my situation

    Yeah, i have purchased a timer for my well pump but may end up not using it due to my water requirements. My issue is my well is dry this time of year so it may need to operate throughout the night and day at various times to fill a 2500 gallon water storage tank. Thanks for the link. I am...

    Do I need a DIY Low Battery Disconnect, or buy one for my situation

    The purpose of disconnecting battery from inverter is to prevent damage to battery from excessive power draw. Yes, my inverter have a low voltage disconnect, but for it to disconnect, my batteries would be drained well below 10% charge capacity. I have a well pump that may drain all my power if...

    DC solar AC unit

    To the original author of this thread, based on my newly installed system and your requirements, you will need at least 400ah 24v (10kw hour) lead acid battery bank. You can get away with less using lithium batteries. I have (8) 270w solar panels generating approximately 1,650 watts max from...

    recommened 24c DC to 240v AC

    Fred, i am thinking about buying the same 4k watt Sungold inverter to power a 1hp submersible well pump in California. The well pump is setup with 3 wire total for 240v and is currently connected to a Honda 7000 generator. Using an Amp Meter clamp, the Honda generator sent around 9 amps on each...

    Battery bank drop in voltage after dark and lose capacity too quick

    Thanks for the reply, I will have to customize the charge parameters since it is currently set to the Flood Acid Battery preset on my Charge controller. I am afraid to overcharge my batteries using custom settings. I do have constant power draw on inverter with my Refrigerator, and small...
