Our eletrical system is controlled by a pms2000gt

This last trip the polarity light came on. We turned off the charger switch at bedtime and switched it back on in the morning and within a couple of hours the light was back on.

Any idea what could be causing this and is anything unsafe whilst it is on? This is the first time it's happened in 5 years of owning the 'van.
