question

It took about 5 seconds to do a google search and find the datasheet for a Multiplus 2 10kVA.

100A maximum AC input current + 43A (10000/230 powerassist) = 143A Total

Hi,

I'm not really sure what you are expecting to see?

The current datasheet quite clearly states that the maximum ac input and changeover relay are rated at 100A. The same datasheet also states that the inverter has a continuous rated power output (at 25deg C) of 10000VA. At a power factor of 1 (ie a completely resistive load) and an output voltage of 230V, that equals 43.48A (10000/230), therefore the unit is capable of passing through 100A with powerassist adding an additional 43.48A.

No, the datasheet does not say in words what I have said above, it gives you the relevant figures to be able to calculate it.

Hi,

First, thanks for taking the time to help me. I'm looking at these devices for the first time.

Yes, we can make an assumption/calculate with the values on the datasheet. I don't work with assumptions.

In the "Multiplus II manual", which is valid for all the models, this is what is stated:

AC-out-1 The AC output cable can be connected directly to the terminal block ‘AC-out’. From left to right: “N” (neutral), “PE” (earth) and “L” (phase) With its PowerAssist feature the inverter/charger can add up to 3 kVA (that is 3000 / 230 = 13 A) to the output during periods of peak power requirement. Together with a maximum input current of 32 A, this means that the output can supply up to 32 + 13 = 45 A. An earth leakage circuit breaker and a fuse or circuit breaker rated to support the expected load must be included in series with the output, and the cable cross-section must be sized accordingly.

Yes, we can make an assumption that this is only for the 3kVA model, and that for the other models we just replace the numbers. But in the end, it is an assumption, and, if for some reason something goes wrong, the liability is on our side. That's why I don't work with assumptions.

I think something is missing in the documentation.

Yes, the documentation is in error here. But as others have said, it's easy to use the formulas provided for the 3000 VA model for other models.

Relying on full shore power plus power assist means that the inverter will overload if shore power is missing unless you shed some loads when shore power disappears. Models with two AC outputs can help manage the loads since the second output turns off with loss of shore power. However, the second AC output is often rated for less current than the main one. The data sheet lists the max AC 2 output current.
