Maverick; it's 6.0 kW of PV, 2 Midnite Classic 200s, Conext XW+ 5548, and 8 Crown Embassy VRSLA 6CEA390 for 390 amp-hours, 48v. Concerns me to be cycling those batteries every night when it's not supposed to happen as per the permit package. "Notes - Battery Backup: During an outage, an automatic transfer switch in the inverter opens the grid interconnect, isolating the inverter from the utility to prevent back-feeding the local power lines. The inverter then draws from the battery bank to provide AC power to the backup sub-panel. Battery power is only used to provide power to the backup sub-panel. The Battery inverter only sells energy to the grid from the solar array when available and not from the battery bank. The battery backup inverter is UL 1741 and IEEE 1547 compliant."
