I have connected the Chint meter to the DTU and selected my export as 0. For some reason the system does not limit the solar. It does not look like the DTU and Chint meter is seeing each other . I did connect it correctly according to the manual. Am I missing a setting?

August 28, 20214 yr Hi PeanuTG Thank you for the reply. I still have the same issue and I tried everything to my knowledge so far. Do you have the same setup, if so would you mind sending me a couple of images of your setting? 0796951133 I really need the help as I am paying more for electricity when my solar is on than when I switch it of for the day.
September 7, 20214 yr It looks like I sorted out the meter setup by ignoring the serial number of the meter. I have used a couple of 0 and 1 at the end. This however did not fix my export issues but at least I can see the grid power draw. At the moment I use a smart plug to disconnect my solar when my geyser is not on. The image is when I do not use the smart plug to control the solar. If anyone has a DTU-Pro with Zero export working, please contact me if you can help. 0796951133 Thanks. Jordaan Botha

I had a 4 way combiner unit so connected 4 x 425W panels to a single input Hoymiles 1200 - also worked well. So then I went big and attached 2 panels per DC input for 3 inputs and 4 panels on a single input. It continued to generate power and worked well. No problems. The comment from Hoymiles support was it is a waste of power but nice to know IF I had extra panels to use? The Hoymiles 1200 appears very well built! Barry Is it correct in saying that the Chint meter is installed just after the street meter, meaning live and neutral into Chint (Single phase) live and neutral out to incoming earth leakage (63A) Rs communications to DTU unit please could someone advise on that,much appreciated

January 1, 20233 yr I was wondering if anyone could assist with advise on connection off the chint meter, do you install it just after the street meter ,live and neutral into it, live and neutral out off chint meter(Single phase) to distribution box,connect com ports from chint to DTU unit, then the ac out off the Hoymiles to a circuit breaker in the main DB box?

I cannot be of any help regarding the DTU, but i can tell you the insertion of chint is correct, that is the point where the inverter wants to know if power is exported to the outside grid. Are you using the chint DDSU-666, and if so, the old type or new one with buttons? And on the side of the shipping box there if factory default protocol setting printed. What are they?

In general the chint meter must be on the incoming grid to your main db box. If there is a main isolator or ELD and their grid side connector are not tapped to other circuits, then it is possible also to insert the chint after the main circuit breaker.
January 1, 20233 yr Example factory setting. This one shows modbus as the default protocol, with slave address of 20.

January 1, 20233 yr 1 hour ago, WayneS said: It is using modbus its also the one without the buttons older type @WayneS the ddsu-666 supports two protocols : 1. DLT-645 2007, which is the standard chinese protocol for electric power meters 2.Modbus RTU It appears your factory setting is DLT-645 because of the 6 digit hexadecimal address code supplied. You can check this out by powering the meter and you will see different metrics displayed each couple seconds later. The protocol is displayed either a NODBUS or DLT, can you confirm? Furthet, I know nothing about your DTU, so you will alsi have to investigate what protocol it needs. Either modbus or dlt. EDIT: tip : it is possible to power the meter for testing purposes and convenience from a plugpoint with cabtyre and male plug, screw the other end of the cabtyre to the input live terminal and input neatral terminal.SAFETY: Keep the plastic latches of the meter clipped when working with live voltage.

December 4, 20232 yr Hey Guys, just reviving this post for those you are still struggling. First off, you can't take a chint DDSU666 off the shelf and use it, these have to be programed by Hoymiles with a recognisable serial numbe which will be stuck to the side of the chint meter If that is all in order, the chint meter can be powered from any where, but you need to install the 100A CT clamp. on mains live wire, basically the live live coming from the street, then you have to ask your installer if.you are not able too. To add the meter to your plant. Just out of interest. I installed several installation, but Ellie's for a while now no longer imports Hoymiles, where are you getting your units or are these old installations,. I am busy in contact with Hoymiles trying to revive these and plan to bring some back into South Africa,
