We have several RS800's that we have gotten replacement batteries for but many of the units just flashs all the lights on the front and the powerchutes software shows internal error.
Some of them also just trip back and forth from online power to battery. Our working RS800's do not trip back and forth using the same power outlets.
I have read it could be a capacitor issues with the charging and inverter circuits.
Does anyone have a diagram for this unit or know what the power could be?
