XT90 TO DC7909 Cable

Had problems changing my AC200Max after keeping it in humid conditions I guess, it wasn't charging on AC, randomly showing 100% or 0% on the display. Using this adapter I was able to connect the DC input to the normal AC power socket, now the battery would shut down and restart continuously. I forced the power button to stay off with a small tube against the wall and battery charged 100%, now it charges on AC as well. Still getting alarms sometimes and showing 100% when is actually empty, so it won't charge on AC and would shut down if trying to output power, but this failure seems to happen only occasionally now. When it does this, the trick with this DC adapter and forcing the power button to stay off works. Hope this will help someone.

All the materials and cables are solid, thick and great quality. I run a AC200P with B230 expansion on the farm. Using their enhancers and old solar panels to charge them.

This is a quality item and works very well with what it was designed for

No idea why this was suggested to purchase

And extra cord but I have tried it yet but I guess it will come in use
