Old Sterling Inverter charger power saving function problem


Featured Posts

Hi all, I have the pictured Sterling inverter charger, probably about 15 years old as I think it was fitted to the boat from new. It has a power saving function which keeps the inverter in a standby mode until a demand is detected. The problem is it now seems to be having a problem detecting when there is demand, particularly from small draw devices. I believe that it is possible to deselect the power saving function? Just wondering if anyone has or has had this type and knows how to do it. I am currently working around the problem by switching on a 230v lamp which brings the inverter out of standby mode so that I can then use the device I actually want. Thanks in advance for any advice.

The power saving function works quite well, but as you have observed, it does need a reasonable current draw (around 1+? amps) to trigger. Unfortunately there is no way to adjust this threshold.

BTW, I do hope the box has some good ventilation as it does need ventilation to disipate the heat when working hard.

Hi all, just in case anyone else has this problem with this Sterling inverter charger and finds this post on a search, I now have the pictured instruction sheet which shows how to program the settings including switching off the power save function.
