Hi folks, after some info on the display LED's on the front of an Acrel 10R meter.
I am not convinced the CT clamp has been fitted the right way round, as I have found conflicting info on the internet - some say arrow to grid, another website specifically says arrow to grid if used as a PV meter, arrow away from grid if used as a grid meter. I can't find any clear info on any ACREL literature....
What does the "-" LED indicate, the chinese instructions with the meter are not clear, can anyone tell me if the "-" is indicating power to grid or power coming in from the grid, as again I am finding conflicting info.....!
Here's the issue I'm presently trying to resolve. I've other issues as well, but I'll concentrate on this one for the time being, please refer to the attached schematic.
I've been having problems with a Solis RAI charger & Fox-ESS LV5200 battery combination since installed. The installer is useless, to say the least.....
The RAI is programmed - correctly - to charge the battery from grid power between 00:31 and 04:29, which it does. But, roughly 5 minutes later at around 04:35, it then starts to charge once more even though nothing is set to charge. At this point, it draws power from my other storage system (Puredrive Purestore II AC) which has also been charging from the grid at the same times, continuing to draw power from the Purestore until the Fox battery is fully charged. There is no interconnection or communication between the two systems (RAI and Puredrive).
The Purestore is installed within the house close to the domestic power consumer unit and works correctly with no issues and has done since installation over 18 months ago. We have two solar inverters in parallel, each with their own panel arrays, these are located in a workshop some 30metres from the house. The RAI unit and Fox-ESS battery are also in the workshop, the PV CT Clamp for the RAI being fitted around the combined output from the two circuit breakers for the two inverters (see schematic). The RAI mains grid connection is to the consumer unit (breaker panel) within the workshop, from where it can feed back to the house. The Acrel meter is on the incoming grid power feed into the house and connected to the RAI unit via a 30meter Cat-5 cable. The solar PV clamp is correctly fitted and there is no solar at that time of the morning to "trigger" the RAI into charging, so I do not understand why it starts charging again outwith its programmed times?
My limited knowledge suggests the RAI should only charge the batteries under the following conditions:-
a. When programmed to charge from grid,
b. When house demands are met and surplus solar is available (PV CT indicating power coming from solar, Grid CT indicating output to grid)
This leads me to think there could be an issue with the signal from the Acrel meter.......
