The Fluke 393FC clamp meter actually says CATIII/1500VDC on the front.  They're not cheap...
A 3.5 digit 4.5 digit 5 digit 5.5 digit 6.5 digit 7.5 digit DMM is good enough for most people.

Is it a problem that the Amprobe meter is only rated for Cat IV 1000V on the front panel? In the specifications it says Cat IV 1000V AC / 1500 V DC which I find confusing:

1000V AC is the RMS value of a sine wave so the peaks will be at 1414V.

1000V AC is the RMS value of a sine wave so the peaks will be at 1414V.

I think he knows that. What he means is that in the IEC tables ac rms and dc are the same for CAT rating testing.
Also a little known fact is that there are 2 CAT IV ratings, one with basic insulation and other with reinforced, the latter having a much larger testing voltage.

Hi,

For that I'd grab some resistors and build a fixed x100 voltage divider* to attach to the output then use a 10V multimeter to measure it. Put it inside a well insulated box.

For private use, I would do it also.
At work, it´s a little bit "different"...
Interesting to see that the brymen can handle voltages over 1000v, but like it´s mentioned before, it is not specified so it won´t be calibrated.
Actually it seems there´s no alternative to the beha-amprobes, the linked UT-196 seems nowhere to get.

What was the problem with the HIOKI?

You could also go with something a bit more upscale

We have an old Brandenburg.

Unfortunately the Hioki DT4254 is discontinued and is replaced with the DT4261 and P2000 HV Probe. Although Farnell UK still has some until stocks are exhausted. The BK Precision is also discontinued, but there seems to be a bit of availability.

Those MajorTech units look interesting, but poor availability in Europe, same as the UT196, interesting unit but does not appear to be available in Europe yet.

Some of the test equipment designed for solar PV will go up to 1500V DC. The Amprobe, Fluke 393 and HT65 already identified are the most common options available in Europe, without going for a specific Solar Tester.

Time Electronics do the 5075 7.5 digit bench multimeter that will measure up to 10kV DC if you really want to go for it;

If you want to keep them away from the voltage, you could always go for a Seaward KD1E/15D, that has a digital readout!!

old high R x10 probes had 90..990 meg R,to working together 10 MDVMs, others were for 20,000 ohm/ V VOM.

also Voltech made dedicated Hv DVMS, checking ebay and ham radio will eventually get,you a solution

There's loads of Fluke 27FMs on eBay that come with the HV probe:

But for a fixed installation like this I'd build a resistor divider. Maybe even build a cheap multimeter into it as well.
