So, on Saturday morning our iBoost went pop, tripping out the consumer unit switch.  Slightly concerning for a while, as it sits on the same fused spur as our ASHP controller, and our solar inverter gets its mains feed from the same trip switch 😯

Spent about 20 minutes wandering around turning all the various bits off and on to work out exactly what the problem was, followed by a couple of minutes with a screwdriver and I had the iBoost disconnected and everything else up and running again.

We've had the iBoost for about 6 and a half years, so it is way out of warranty, so we'll be looking at getting it replaced.  I would have no problem with going for another iBoost, but just wondering what units other people use that they would recommend?  More importantly, are there any that people would advise to avoid?

Thanks

Sorry to hear that. We have an iBoost too (three years old now) so will keep an eye on it. There are many products on the market now.

I’ve heard good thing about Eddi - https://myenergi.com/product/eddi/

Will be interesting to see what other products homeowners are using.

We have a solic, it's fine, does what it says on the tin. No frills though and no monitoring system

12kW Midea ASHP - 8.4kw solar - 29kWh batteries
262m2 house in Hampshire
Current weather compensation: 47@-2 and 31@17

We have an Immersun diverter which I do believe I installed in 2015. The unit itself has worked faultlessly, and it is possible to divert excess solar energy individually to each of three 3kW loads. One of the aspects that I like is that the output can be switched on and off controlled by a thermostat using separate control wiring, so the control element does not have to be rated for 13A.

I also find the monitoring service provided to be very useful, in not only quantifying how much energy is being diverted, but also how much energy is being produced by the solar PV, how much energy is being used within the home and also how much energy is being imported or exported. There have been a few occasions when the monitoring service has failed to operate for various reasons and it can take several days before full service is restored. As I write this I am now awaiting Vodafone to hopefully sort out a problem with data communication through their system, after a recent very short power cut upset the apple cart so to speak, and it is taking time and effort to try to discover where the problem lies and to get it resolved. One of the drawbacks with modern technology that you cannot easily interrogate. 😌

Hi Everyone,

I would welcome some help from you Internet Guru's with a recent problem.

As I have mentioned previously we have an Immersun Power Diverter, which performs very well in utilising our solar power in the most useful manner.

A week ago last Friday we had a very brief power cut, which was long enough to switch everything off that did not have battery backup. This of course switched off the Immersun unit and our internet router, and when they rebooted I noticed that the Immersun data was no longer available on my laptop. I reset everything at our end and raised a ticket with Immersun to reset their end (which unfortunately is often necessary). After all the resets I could once more login to the system, but their was no data being displayed. I have now spent well over a week in communication with both Immersun and Vodafone to try to restore the data feed. Immersun state that they are not receiving the data feed from our end and Vodafone appear to be staffed by a load of idiots that don't have a clue of how their system works.

So my question to all you Guru's, is do you know anyway in which I can monitor the data flow through our router, to try to locate where the 'black hole' is located?

@derek-m, that can be frustrating. Whenever we have these short powerful failures I always dread the restart because inevitably something stops responding or communicating. The reason that this happens, in most cases, is that the router re-issues IP addresses to devices on your home network and this can cause "identification" problems for certain software. I don't that this will necessarily be the issue in your case, but it might be.

What router are you using? Is it Vodafone's own router? Getting admin access to the router will allow you to see which devices are connected the router and what their IP addresses are. This could be helpful to know and you can check the settings on your Immersun software.

On that note, how do you access the data from your Immersun – is it via a programme on your computer or via their website?

Hi Mars,

I have eventually managed to convince the Immersun Help Team that the problem was at their end, and full service has now been restored.

I can access the data either on my laptop or mobile. The data shows precisely where energy is coming from and being used, so is highly useful in minimising our import from and export to the grid. My objective is to be as 'grid neutral' as possible, and it is also providing useful data so that I can assess what size of battery storage would be most useful and cost effective.

I tried looking at the settings of the Vodafone router, but could not see if data was actually being transferred. The Vodafone 'help' team are almost a complete waste of space. If it was not for the fact that we have reasonably reliable broadband at a reasonable price, I would search for a provider with better customer care, if such an animal exists.

@derek-m, glad to hear you’re back up and running.

We’re with Sky - their customer service and support is decent, but they are a greedy company that will fleece you given half a chance. We’ve stopped all our TV and add ons with them because they’re sharks… we’ve kept the internet because the price is still OK and it’d be too much of a hassle to change.

Decided to go with another iBoost in the end, which is now fitted and working.  Our DHW tank has two immersion heaters, so after discussing it with the sparky, we decided to connect both of them to the iBoost, and disconnect the bottom one from the FTC.  This means that on nice sunny days we will get a full tank of water at 60C, rather than just the top half as we were before.  This will hopefully mean that during the summer months we shouldn't need the ASHP for water heating at all - time will tell I guess!  There were also safety reasons behind this decision as well.  Our installers in their (lack of) wisdom had connected the iBoost and the FTC to the same 16A fused spur.  While it is highly unlikely that both would be turning on the immersion heaters at the same time, if it did happen, then pop goes the fused spur!

I will have to keep an eye on tank temperatures over the winter months to ensure that it regularly gets up to 60C, because the FTC now doesn't have control of an immersion for the Legionella cycle.

@peterr, thanks for the update and look forward to hearing how it performs.

Seems I was a little optimistic!  Although, even on relatively cloudy days we still get a full tank of hot water, this doesn't quite last us through, so the ASHP fires up most mornings for about half an hour to heat the water.  The main reason for this is that my wife has a joint condition that means that the only way she can get comfortable to sleep is to have a hot bath in the evening, so that runs down the tank a bit, and there isn't quite enough hot water for three showers in the morning!  

On the plus side the ASHP kicks in after the solar PV has started generating, so we're not drawing as much from the grid as we would if we were heating water at night.

@peterr here's hoping the op looks at this.

 

How are you getting on with new iboost?

I has a similar situation where my old one went pop after 6 years and so replaced like for like. 

I find the new one spends more time with the cooling fan running and no output to the tank. 

So far I'm very disappointed with it where as the original was far better. 

I'm looking at swapping it out but need the two outputs so when one is hot the second kicks in... Very few do this 

I'm also wary of the electrical noise that some cheaper units have with the thyristor controls.
