EG4 Solution: EPS Overload with Paralleled 6000XPs

[EG4_Jared]

When working with the 6000XP and the minimum 200Ah battery bank recommendation is met with all paralleled inverters, it's important to set the appropriate discharge current limit, especially when multiple inverters are paralleled.

For example, if you have two 6000XPs in parallel with 600Ah worth of batteries in the battery bank, you will want to set the discharge current limit to 280A.



Properly configuring the discharge current limit helps prevent common issues in paralleled systems, such as EPS overload or unexpected switching to grid bypass even when the battery percentage is above the on-grid discharge threshold. By ensuring the discharge settings are aligned with your setup, you can maintain smooth operation and avoid these troubleshooting headaches.

For optimal performance, always refer to your spec sheet and make necessary adjustments to the discharge current limit based on the number of paralleled inverters. This proactive approach ensures reliable and efficient energy management in your system.

Did you mean 280 amps vice 280 amp hours (Ah)?

Just to be clear. Are you saying that if the discharge current limit is exceeded as when the PV array output decreases to the point more current is drawn from the batteries and exceeds the discharge current limit the inverter will switch to grid regardless of battery SOC. Makes sense.

How do you arrive at setting discharge current limit to 280 amps since based on the output power rating of the inverter it should never draw 280 amps

Yes, definitely a typo on my part.

When in parallel, each inverter would be capable of the full 140A discharge current.
