System not drawing enough power from battery bank, so most power needed for loads comes from grid
I have a Conext SW 4048 inverter/charger AC coupled to an Enphase micro inverter (AC output) solar system. They are coupled at a critical load panel. No matter how I adjust the settings, the fully charged battery bank only produces a tiny part of the load draw. If the load draw is say 1,500 watts, the inverter/charger will only take 13-87 watts from the batter bank and the rest is being pulled from the grid...EXACTLY WHAT I DON'T WANT. The point of this system is to charge the batteries during the daylight and them power as much as possible from the batteries at night....yet no matter how I adjust the settings, I barley get more than a trickle contribution from the batteries.
