Morningstar Prostar 30?
Something strange is happening with my system. Solar array is generating power and when the controller senses 28+ volts it goes into "regulation" which limits the charging of the array. It was showing 26ish volts but was still in regulation so I reset the controller and instantly it showed 28 volts. It seems like the readout is stuck on the 26 number but in reality the voltage is 28. It also relays that 26 number to the SW4024 inverter so it does not go into AC Support mode but as soon as I reset the controller the relay kicks in. Has anyone seen anything like this?
