Aux Port Now Working
I added this as a comment to someone having problems with the Aux Port, and thought there may be some other poor soul struggling like I was? After much head scratching and throwing things about, I've found out how to make the Aux port work. There are three settings, battery SOC to make the port live, battery SOC to turn it off, and the critical one, the minimum solar input for it to happen. (I had the solar setting to match my maximum solar input so the bl***y thing never switched on unless the 'Grid on always on' box was ticked and it then stayed on permanently). I use my Aux to put spare solar into my car, and I want the inverter batteries to be as highly charged as possible when the sun goes down, so I have set the minimum solar input to 1500W, the SOC to switch on at 95%, and SOC to switch off at 90%. Once solar output drops to 1499W, the port switches off, and the inverter battery has at least 90%, and I still have 1500W coming in from the sun.
Hi Sean,
In a rush, misunderstood your reply. I considered using my PodPoint 7kW EV charger, but I would have needed a manual isolation switch in the supply to the EV charger, with a contactor, energised by the Aux port, to bypass the isolator. This would have meant a manual operation each time the EV charger was to be used off grid. However, my max PV is only 4.5kW, so when the sun is bright, there still won't be enough solar energy to power the EV charger without running down the batteries, so the Aux port will be on and off like a minister's trousers. I did a study on analytical trouble shooting, and things only fail when being used, so for my particular case, I use the 13A charger lead that comes with all? EVs, and if the sun's shining, it charges the car whilst often charging the batteries avoiding the Aux port constantly going on and off.. It needs no attention from me, as I leave the EV plugged in whenever I park up. My settings are 97% on, 92% off, minimum solar input 1500W, and have one single socket outlet off the Aux port. For the record, over the last 2 months, my 12 panels and 5 x 5.12 batteries have make me almost totally independent electrically including around 150 miles per week in the EV.
