When the inverter is using this mode, at night or when there is not much PV power, are the laods seeing inverter output power or does the grid pass through the inverter, as in bypass the inverter directly to the loads. The manual says:
"In the morning, the PV system begins 3-stage charging of the batteries at bulk stage and power from the grid passes through the XW+ (including XW) to the loads." That is not really clear. What does "passes through" mean? Does that mean the grid charges the batteries with the integrated charger simultaneously with the inverter outputting AC power, or does that mean the utility power bypasses the inverter and powers the loads directly while the PV system gets the batteries charged up? While on the subject, and I don't think this is possible, but I have a Conext off-grid client that wants to have "clean" inverter power all the time rather than the generator power bypassing the inverters and powering the loads directly during battery charging. I told him it is not possible without using an external battery charger and eliminating the generator AC input to the inverter. I think I am correct on that, but I'll take any suggestions!
