I have not tried bringing it out of bypass becaue the power modules show off. I figure that's just asking for trouble. When the 2 modules first failed, it went into bypass because there was too much load on 1 leg and it went to overload. Once I got the phases balanced It came out of bypass on its own with the 1 power module still running. The original power module shut down and it went to bypass when I plugged the first replacement module in.
Sounds like it might be a battery problem. I'm getting replacement batteries on order today.
