Well it took a while and I finally got EG4 battery comms working. Then I flashed the EG4 batteries to the latest firmware and BLAM no more battery comms. After screwing around trying to again get battery comms working again I told myself screw it and changed over to voltage for battery control like so many others.Maybe they didn't think it was important. Because they would rather everyone use communications, and work with settings based on %. But I prefer voltage for these settings.
Surface voltage fluctuates more based on current flowing. If the sun rises strong, i switch back to battery sooner. If it's cloudy, I switch later in the morning. This avoids short cycling Because of trying to narrow the range with settings based on %.
