EM115 meter

I wonder if anyone can help please? I have a solar array fitted over 11 years ago. This year we had 4 x 2.6 batteries and an AC 3 inverter. My local installer at the time couldn't get the hardware, he was happy for me to supply and he would fit. This was fitted end of March 2022. We always intended to have the system set up as EPS this the installer did last month. While setting up the system it was pointed out that all the contents of the batteries was dashing out of the garage. The fault was traced to a faulty EM115 meter. He did have a spare which he fitted and with the help of Givenergy commissioning engineers the fault was confirmed as a faulty meter. I have tried for the last few weeks to get a replacement meter for the installer and a spare which I propose to keep. Does anyone know where I can purchase two EM115 meters please?

Thank you very much for the info. I have ordered two. I assume that the OB115 is the same as EM115 meter.

RegHall identical.
Just order the ID number you need.
ID1 grid
ID2 solar if needed
ID3 2nd solar if needed

Once again many thanks for the info. I now sit back and watch for the postman. Thanks again.

RegHall , you had me worried describing the contents of the batteries dashing out of the garage. My initial thought was you meant the chemical contents, then thought the electrical energy. Hopefully you meant the latter.

I have also bought some OB115 meters, and installed them in my consumer units to provide sub-metering of different main circuits. Luckily I had enough spare ways to add the required 6 Amp MCB to power them. I will be adding 1 to monitor/verify the import and export of the ordered 5kW Gen2 hybrid (installation now delayed a 2nd time, predicted end of Jan 2023).

RegHall Looks like the OB115 has a solid core CT option. The cable it needs to be wrapped round will have to be removed from the termination to slip it over, so it will be a pain if it's fitted the wrong way round. If the meter ever goes faulty, the CT may be able to be re-used, unless that is the cause of the problem.

If you ever do have to change the OB115, either get a sparky to do it for you, or ensure that the wire that it is measuring the current in, is isolated because an open circuit CT can generate very significant voltage across the terminals. Some have a load resistor built in or Schottky diodes to limit the voltage, but who want to test? If it's a split core CT, then unclipping it from the cable while the EM/OB115 is changed would be another way to remove the potential risk.

I chose the solid core CT for sub-metering as it is supposed to be more accurate.

For fitting/swapping out I can switch off the CT monitored circuit, and test for safety before exposing any terminals. It is my day job to test for safe working with electrics though, so not recommended for everyone.

They have both open and closed CT. Closed is more accurate

Hi Simon you were right it was the electrical energy that made a bid for freedom, my thought was that it was my money that was off down the drive. I do not propose to fit it myself it will be the electrician who fitted my system that will do it should it ever be needed. I am only getting a spare as an insurance policy, the first one failed without any prior notice it would mean that my system would be down for as long as it takes to get a replacement.

Many thanks for all the help and advice.
