Conext SW4024 Usage

I have had the SW4024 for a several months and have used it in a few different ways; standby as a UPS that keeps batteries in Float and in AC Support that uses battery power along with grid during the day when the array is producing power. My current mode is to have the AC Support function enabled during the day, array producing, and disabled manually when the sun goes down. I have had the Combox installed for a few months and that has shown me more detail. So far my power, grid and load usage is fairly consistent no matter what mode I am in. I have tried leaving it in AC Support and it cycles at night and I have disabled AC Support for days at a time. I have been communicating with another member, comparing notes. I would like to hear from others as to how they use their SW4024 and what their battery charging settings are to get a good charge.
System consists of SW4024, SCP, Combox, Morningstar PS30 PWM charge controller, 400ah battery bank (4 X 6 volt Lifeline AGMs), solar array.

    Hello,  I have two SW4048 inverters (48 volt version) stacked in parallel and have had problems from the beginning but I am working these out.  As far as the AC Support design design it leaves little to be desired.  I am going to try to use a relay to kill the AC (grid) input when my battery bank SOC reaches a predetermined level to more utilize the solar during the day since this inverter does not do it very well.  I am going to use the aux output from one of my MPPT60-150 charge controllers to operate a 24VDC relay.  I am not sure if your Morningstar controllers have an aux output based on battery SOC to accomplish this.  Right now I am testing a few candidate relays to see how well they work before trying it.  People have used timers and other means to do this as well.  Check the threads on here since they are very informative.  Good luck....
