Hi all..
Just wondering about the above which I have fitted at ours.
I am also seeing 20-30w of power pulled from the grid on occasion when the Solic is sending power to the immersion.
I have contacted the seller who says that it is likely down to electrical noise at our property. He also says that the unit has to slide to zero which I can understand. My observations lead me to think there is something else going on though.
Just wondering if anyone has any thoughts on this?
I'm not an electrician, nor even a PV professional, but I've been used to doing practical electrical things now for over 50 years, and I reckon I'm perfectly capable of following installation instructions, especially if they are as straightforward as for the Solic Wireless immersion controller/diverter.
Your posting about the Solic 200 is the only mention I can find which has something in common with the problems which I am experiencing. Now I am wondering whether you, or anyone else, has any more useful comments to make about this curious phenomenon of importing from grid.
My Solic Wireless does more than reduce PV export to zero; it goes further and actually draws in power from the grid. However, all the LEDs on both the main unit and sensor function as expected. For example, at one stage the PV was generating 1150w, nothing being consumed by the house (all circuits other than PV and 3000w immersion turned off), smart meter in-house display showed importing 270w. The actual smart meter also confirmed power being imported. Just as strange is that the power drawn from grid increases with increased PV generation, and decreases with decreased PV generation, the precise opposite of what is expected.
Schematically, this device is installed in much the same way as for the Solar-iBoost, execept that the remote sensor is powered by a plug-in 9v power supply, rather than batteries.
In case it is relevant I would mention that this is a modest 1800w nominal PV installation, installed 2010, with a SolarEdge inverter. Also the mains tails are unusually long (at least 7m), the consumer unit (just below kitchen ceiling) and outside meter box being remote from each other. This is because a single storey extension has been added to the bungalow. The sensor clamp is clamped on one of these tails in the roof space about a meter away from the consumer unit. There are several house circuits very close to the tails and clamping point, but I can see no practicable way of avoiding this, if that is relevant. Experimentally attaching the sensor clamp to a tail in the outside meter cupboard and using an extension lead into which to plug in the 9v power supply, so that could also be in the meter cupboard, made no difference.
Unfortunately it turned out this unit was not new, although it had been sold to me as new. The supplier is willing to provide a full refund, or let me have it at a very reduced price if I can get it working, or supply a new unit at a discount. This will be no good to me if there is something odd about my set up which will cause the same problem all over again.
