SOLIC solar immersion controller

[Launchman1]

Afternoon all, I've been looking at getting a solar immersion controller for my solar PV 3kWp array, and although the IMMERSUN and iBOOST look like the prime players, I'm keen to know whether any of you have had experience with the SOLIC unit? It appears to do the same job as the rest, looks more robust (industrial) and is less expensive than either of the other 2 (including installation), and a 10 year warranty? Any advice from those that have fitted these? Problems? Thanks.

I've been following these types of devices since they first came onto the market and in principle it's a great idea but... there is a but, it's all about technology. As an electronics engineer I fully understand the methodology for modulating power, if the device you are sending power to is greater than 200w you can't use Phase Angle technology, nor can you use Burst Fire. Phase angle will interfere with your invertor and create Harmonic imbalance therefore could result in damage to the invertor for which I imagine the manufacturers warranty won't cover that!

Be careful which device you choose and make sure that it use a sine wave and ask for a copy of the EMC report.

Hi i had 1 of these installed last September along with my 3.92Kw array and can say that I have had not 1 bit of bother with it, it just sits there working away as it should (or not when no excess electricity) I have not used any gas for about the last 5 months as heating off and loads of hot water from immersion for free. Best couple of hundred quid ever spent.

When the inverter sees the harmonic imbalance it shuts down and has to be then started up again resulrting in loss of generation if not spotted at the time. I would recommend the Immersun MKII - easy to install and uses pulse width modulation.
