Still waiting on a resolution with my inoperable AC200P charger. Sent an email and got a reply asking for a video of it not charging and serial number to troubleshoot. Sent it and was asked if it would charge with the car/pv, replied with yes on the car and haven't been able to test the pv, panels haven't arrived yet. Waiting to hear back, sucks this is happening during the short week, everything takes longer to get resolved. Picked up four 100w hqst panels for $288, hope to make two solar suitcases to make it a somewhat portable system for jeep shows, camping trips etc
