Over charging of 2018 Pleasureway Lexor TS
Just recently purchased a used 2018 Pleasureway Lexor TS which is built on 2017 Dodge RAM Promaster 3500 chassis with gas V-6. It has 2x100 AH Lithium Batteries, 95 watt solar panel with GoPower 30AMP PWM solar controller, Progressive Dynamics 45 AMP Lithium Converter, Xantrex Freedom XI 2000 watt inverter.
On the last two times that I have driven for a couple hours, my solar controller display has gone into a rapid blinking state which the manual says indicates that it read a charge of 15.5V or over surge.
I'm thinking neither the solar panel or the converter could be causing that, leaving the alternator or separator that could be causing any possible over charge surge. My thoughts are to disconnect the solar panels and go for a drive and have a friend record the voltage readings of the coach batteries watching for any time over 14.8. Your thoughts on what might be causing the surge and a easier way to test the alternator effects on the coach batteries??
Thanks in advance.
