Low Power Mode - Octopus Fusion
While low power mode appears to be working as described, there is an issue with the implementation that I'd not considered.
As the battery on my system had not had an opportunity to fully charge for a few days, I decided to charge from the grid overnight.
What I hadn't considered was that in the absence of solar and as the SOC dropped below the set threshold, the inverter switched itself off and could not accept the grid charge.
If you are planning to change your tariff to Octopus Fusion or any other overnight cheap rate tariff, unless I'm missing something, it will not work if the the inverter has invoked low power mode and shutdown.
It would be better if the inverter woke at grid and/or solar feed, not solar alone.
Any thoughts on how this issue can be circumvented?
I have also fallen foul of this oversight. If somebody could point me in the direction to where it is mentioned in any documentation, I'd appreciate it. Because I looked and couldn't find it anywhere.
I saw Keith Gough enthusing about this great new feature on YT and on paper, it looks like a good thing. But the ramifications for users on agile tariffs was completely overlooked. I've since had to disable it.
However, given that my inverter will not keep its remote control function enabled, I can't reliably charge from the grid anyway. Search for remote control and check out the post about it. I would suspect that more people have malfunctioning inverters, but won't realise it until they try to use a time-of-day tariff.
