Twin eg4 6500ex48 inverters with 4- 48vdc 100 ah Batts. Each inverter has a 340v 3780w array tied into its pv 1 input. Inverter # 2 has an additional 750w 100v string tied into pv 2.
My system is utilizing the "user" setting for battery charge control. Limits are set per eg4 batt spec sheet.
System has been harvesting 35- 40kwh per day for 2 weeks.
This morning at 8:30 am the inverter arrays were producing 1.04 kw for #1 and 580w for Inverter # 2 . These arrays are usually each producing 1.20- 1.38kw by this time. It acted like the panels were shaded. I checked all the pv connections and voltage at each panel. Each inverter array was producing + 300 volts .
Did a complete system shutdown and restart , system rebooted and started charging at
2.31 kw for # 1 and 2.81kw for #2 at 10:30 am. Historical production for each array at 10:30 am : #1- 2.59 kw , #2 - 2.71kw.
Anybody else seen this?
