19v 28v 24v 27v just goes crazy. But test on the inverter 28v stable. Now we have load shedding so no power input. Test the batteries and it still jumps but all low low readings. As soon as I switch of the unit. It gives a stable reading of 24.4v. Possibly my meter is getting some kind of inference?
Thanks alot, Stange thing is if I test at the terminals at the back of the unit. The voltage is stable but when I test on the batteries the readings go crazy.
