Differing readings from charge controller and inverter.
Hello helpful solar people. I have 14x 80watt 12volt panels and 7x 12volt optima yellow top deep cycle batteries. A 60 amp charge controller and a 1500watt inverter. The charge controller in full sun is reading 14volts give or take and telling my my batterys are at 100 percent. I have a volt meter hooked to my inverter and is reading 12.40volts under the same conditions. I have the batteries in series and the invertor and charge controller connected at opposite ends of the bank. Any ideas? Thank you!
