OHME and Solar

[mg4mc]

I don't have solar, but I see in the latest OHME beta app that there is now a setting to switch it on. Not sure if this has been posted before, but I hadn't seen it.

From the help it appears that it will switch to solar charging if the available solar exceeds half the minimum 1.44 kW required to initiate charging. So if the availble solar power is between 0.72 and 1.44 kW you could incur some full daytime rate costs.

As it's a beta you'd hope that they will add the ability to alter that threshold at some point.

Good thinking.

I have just had solar installed and have an EVSE that supports it (if the muppet installer had installed the ct clamp but that’s another story). I don’t see the value in my situation of using excess solar. As soon as the paperwork is through I’ll sign up for 15p/kWh export and off peak charging is 7.9p/kWh ergo overall cheaper to export and buy back at night. If you were on a flat rate or doing something funky like with agile I can see it helping but other than that….

I guess it could work for me as I'm on FiT, I could push the extra above what the granny can provide into the car, but that would max out at 3.5kW from my panels so not really worth it for the few months that is likely to happen.

For sure if you are lucky enough to have FIT or a different supply tariff.

I’m a bit paranoid also - keeping the car awake for so long on such a slow charge huuum with the small output.

Think this is part of the EV adoption issue, my electricity tariff is different to someone else’s, the sell back is different etc it’s all a bit messy. If only it was a simple system where everybody paid what it cost to generate and distribute electricity plus a small margin for upkeep, kind of a state backed energy supply for the good of the country. I think I’d call it the CEGB with some regional offshoots for billing haha. Everybody could have tariffs that encourage load shifting (think economy 7 type for all now smart meters are a thing) and everybody benefits (no NEED for a higher day rate) except shareholders I suppose.
