Hi 12Volt - not an expert obviously but most MPPT controllers have a "Load" connection where the draw from applications is regulated through the controller and if the battery charge drops below a certain threshold the feed is interrupted to protect the batteries. I also assume that the fancy...

At my off grid cabin I have a fairly small system. I have four 100 watt panels, an MPPT controller, and three identical deep cell AGM batteries (96 Ah) hooked up in parallel. The panels are roof mounted facing south and get great exposure from about 8:30 AM through to about 3:30 PM. On a...

I bought a OOYCYOO 60 AMP MPPT - it was cheap. My rule of thumb for my cabin is don't buy anything that you can't stand to have stolen. A lot of the people in the area (not all - there are good people) like to "hunt" using prybars. The "local" police are about two hours away and their main...

Hi, I have set up a small solar array for my off grid cottage in central Ontario, Canada. Currently I have four 100W panels on the roof (facing south) wired to an MPPT controller, and two AGM deep cell batteries. I am running a Unique fridge (full size) that was designed to run off 12 or 24...

Thanks Mike, I was worried about the idle power draw from the inverter and keep it disconnected (not just turned off but physically disconnected from the batteries) when I am not using it. However I usually have it hooked up from about 7 to 11 PM. I think the manual says it will draw 1 W per...

Thanks for the quick reply sunshine-eggo. So, if I understand you, the numbers I am getting from the controller are not useful in determining how well charged (or discharged) my batteries are. So what is the point of the fancy read out? Can you explain more about the net current flow to the...

Thanks for that answer. I only hooked up a new MPPT controller a few weeks ago and have only monitored it over the one weekend. That being said, on a partially sunny day I was hitting 100% charge on the batteries by noon (peak sun in my location is about 9:00 AM to about 2:30 PM). So it seems...
