Yup. Mines done that once or twice. It seems theres always a 50 or 60 watt draw from battery to XW when in AC Pass Through. Think mine takes about 8 hours to burn that last half volt and begin charging. I have my grid support & recharge voltageset same as yours. I like to dochargingduring the day as I want inverted power available at night & morning when its dark.clyleadams said:Today my system started charging all on its own! I turned off all of the advanced features on the conext except grid support, put a charge block on until 8:30AM, and I set grid support volts and recharge volts at the same value.... 47.50 volts. apparently, we had a nice 120A battery draw at the perfect time and it lowered the battery volts below recharge volts long enough for a charge cycle to begin. If this works consistently, I will be completely satisfied with it operating in this manner. I will be able to use the battery at night and get a charge started after the battery is depleted in the AM.ZimInSeattle said:No, clyleadams, I have not resolved the issue. I still need to wire in the Batrium. In my situation with net metering, grid acts as battery so all excess PV goes to grid. Doesnt matter where the AC for charging battery comes from. Ive just been manually bulk charging every few days. Im pretty sure Batrium will be easy to integrate as theyve already done the code for CAN bus from Watchmon to the Conext Bridge. Conext Bridge has been superseded by Conext Gateway which also has CAN bus interface. Are you grid tied & do you have net metering? So you have 8KW AC coupled into critical load panel? My understanding is you shouldnt have more than the 6.8KW output rating of the XW Pro coupled into the load panel. I have 2KW into load panel & 8KW into main panel. It doesnt really matter where the AC is coupled though except in the case of grid outage which never happens here.clyleadams said:ZIM, Have you solved this problem yet? I have a 6848pro AC coupled with a solar edge inverter. I sure would like it to charge the batteries when the AC OUTPUT side is positive (greater than the load). I've changed every setting that can be changed and it just hangs out at .5V over recharge volts. I have tripped the AC1 breaker but the solar edge inverter outputs too much much power for the Conext which goes into curtail mode which shuts the Solar Edge shuts off with a high freq fault. Also, the power seems to get abnormally flaky with flickering lights and lots of chattering in the Conext. It sure seems like the Conext should be able to automatically charge the batteries to the bulk voltage setting when there is excess power on AC OUT.
