Re: EKM Metering systems for solar PV?

Hi mamrail, You are right, 1 V4 between grid and your main board will give you import and export but total consumption (including self connsumed from generation) will only be reliable when you are not generating any power from your solar because it is not being measured that is why a second meter wo...

Re: EKM Metering systems for solar PV?

You can use just the 1 V4 for import and export on your main board in doing so you will not get the consumption from the sub board when power is being generated nor will you get the amount of energy you have used from solar generation. If you are not concerned about not knowing consumption on the su...

Re: EKM Metering systems for solar PV?

Hi Mamrail, The solution for your circumstance would be along these lines. 1 EKM V4 to monitor the main board with a CT on the main line (import / export) and a CT on the sub board line, this will give you total import from grid and export to grid. 1 EKM V4 on the sub board, 1 CT to measure consumpt...

Re: EKM Metering systems for solar PV?

The software determines import from, export to grid, self consumed and generation as well as distribution between peak, off-peak etc, the software records usage @ 5, 15, 30 & 60 minute intervals, PVOutput can be pushed @ 5, 10 & 15 minut intervals with automatic batch upload on missed interv...

Re: EKM Metering systems for solar PV?

Hi Mian. Like Jamison, I would also go with the v.4 for your solar generation, export and import from grid connection, but I would use MeterMan http://www.mymetermanager.com/ meterman1.jpg for all your monitoring and uploading to PVOutput, It is able to give you and your clients information you cann...

Re: iSerial access gets Malformed Packet

Dandelot. Here is one explanation "Wireshark thinks the packet is malformed. This could be because it really is malformed. A few possible reasons might be because the snaplen causes the packet to be truncated during capturing, or the packet could have been malformed originally by the sender. Th...

Re: Data Source ?

How big is the file allowed to to grow? In theory SqLite databases can grow to be in the Giga Byte range holding millions of records. Does exporting data, like a special period, delete that data from the file ? If you are talking about the SqLite database, the answer is no, you can export the same ...
