After being a little frustrated with lack of detailed information on the original control panel that came with the Prosine, I ordered this gem online. The LCD has two lines that give much more specific information about current flow and voltage of the battery bank, inverter/charger and loads on the system. This panel offers control over the inverter setup as well that overrides the dip switches on the actual inverter body.
As you can see from this image, the old panel was based on LED indicators to show the information. The problem with this approach is that the lights for voltage jump from 11.5 to 12.25 then up to 13.0. Depending on the brand and type of batteries, a deep cycle battery bank is recommended to only drop to a certain percentage before being re-charged. The average is 50%, which for a typical 12V Deep cycle battery is aproximately 12.2 volts and aproximately 12.7 for full charge. The numbers are a little different for AGM and Gel type batteries and possibly various manufacturers. To know for sure, it is worthwhile to find out for the exact batteries you have. The new control panel allows me to see with much more resolution at what state of charge I am at as well as other useful information.
Just one more small change to make it easier for us to keep track of our resources.
