Hi Andre,

This fault a lot of times points to bad batteries. How old is the unit and the batteries? Is the unit still powering your equipment?  I would use a volt meter to check the voltage of the batteries. Just measure the DC voltage at the anderson connector for each of the modules. When fully charged they should be 110 volts each. Do you have another unit that uses the same batteries? If so you could temporarily borrow those.
