Xantrex XW6848+NA planned night time disconnect and mInimize the tare loss Opinions?
Hi looking for a way to shut down the inverter when the battery volts hits about 50% SOC. I do not want to charge using GRID at all and I don;t want overnight tare loss. So this is the plan to use a relay output from the Mppt-60-150 low battery volts to trigger another relay to close the RPO or remote power off on the inverter. The 12volt small relay will drop out on low batt volts, closing the contact shutting down the inverter. I assume if the inverter in shutdown mode goes to bypass mode AC1 grid? I will keep the charger disabled on the inverter at all times. When the sun comes up the next day and the volts are high enough past the clear setting in the MPPT everything should resume as normal? Or can;t you restart the inverter this way ? When I shut down the inverter I will probably lose power to the combox as it comes from the inverter , another issue to address. Or use the supplied power adapter, which would have no power if there was a grid failure..
