repair for Eaton 9PX UPS error "DC bus
As for the "DC bus - too high", this is referring to the voltage of the link between rectifier and inverter. Usually caused by either a defective rectifier not switching the IGBTs to regulate the DC bus, or the supervisor circuit is reading the voltage incorrectly. Either way, it''s a new enough product that it may be under warranty.

Case#10: AC Overload Fault or Bus Unbalance Fault: Case#11: The system connects to grid and quickly disconnects: Case#12: DC Overload Fault: It is typically caused by DC current from the battery that is too large (ex: 4 Ton AC Unit) or too much PV current (3 or more strings in parallel). Overloads can result in F15, F18, F20, or F26. F22 :
Multiplus ignores AC input when battery is too low
I have an issue that only happens when I am connected to shore power and run the batteries too low. A few times I''ve overloaded the AC input by running too many appliances including air conditioners and that trips the shore power breaker. This usually happens when I am on 30amp shore power, even if I set the input current limit to 30amp max.

Yes, the battery selector switch is suitable. The bus bar is only just big enough (IMO) but this can depend on exactly how it is wired. Given your stated loads, the only high current will be the starter motor and as that is for such short periods, the bus bar will be OK but I rather see the 250A bus bar (Blue Sea 2127). _____
6 FAQs about [Battery bus current is too large]
What causes high DC bus voltage when battery is full?
Usually "high DC bus voltage" is due to high PV voltage when battery is full. That's what I would be checking. Battery is only 70% full when faults occur. If I can do it, you can do it. If you have any type of monitoring, can you check what the DC bus voltage was at the time of the fault? It's probably just a momentary spike.
What happens if bus voltage is too high?
Bus voltage is too high or bus hardware overvoltage fault When the DC voltage input to the inverter exceeds the maximum DC input voltage of the inverter, the inverter reports inverter failure of an excessive bus voltage or inverter failure of bus hardware overvoltage. Solution:
How do I know if my inverter has a high DC bus fault?
I also re-tested the first inverter with the high DC bus faults using a meter with max/min capture. The unit faults on high DC bus fault but the MAX DC pv voltage was 364. One thing I did notice was the unit with the high bus faults has the green status led blinking all the time. The other unit has a solid green status led.
What if the AC side voltage is too high?
If the actual voltage does not exceed the safety overvoltage protection value, the inverter has an internal fault; if the actual voltage exceeds the safety overvoltage protection value, If the voltage protection value is too high, you need to determine the reason why the AC side voltage of the inverter is too high.
What if the battery voltage is too low?
The battery voltage is excessively high or too low. No voltage on DC connection. Ensure that the battery voltage is within the correct range. The battery voltage is low. Charge the battery or check the battery connections. The converter switches off because the battery voltage is too low.
What should I do if my inverter voltage is too high?
Ripple voltage on the DC connection exceeds 1,5Vrms. Check the battery cables and battery connections. Check whether battery capacity is sufficiently high, and increase this if necessary. The inverter is switched off due to an excessively high ripple voltage on the input. Install batteries with a larger capacity.
