Small things matter
Re: Small things matter
Well that extra cooling will make them last years and years, it’s the heat that kills equipment!
Wish we still had a Maplin….

Re: Small things matter
I agree on Maplins, defo. Although tbh I was pretty much online buying before I knew of Maplins. Had a wee look at the end though.
The thermostat feedback switch arrived late this evening. Will set up tomorrow and hopefully will have a decent bandwidth so the fans aren't kicking in and out too often.

Re: Small things matter
Ideal, nice job done there.
Be interested to here about the switch timings cutting the fans in and out.

Dundee had a Tandy when I was growing up that was good, when I moved to Edinburgh 28 years ago Maplin was around the corner from my flat.
EBay became my go to for stuff
In the end Maplin became a bit of a rubbish, but was handy for the odd item you wanted then and there, I think it was good to go up and down the isles looking at products though.
Re: Small things matter
Kept it simple, 40 degs fans on, 30 degs fans off. Once the sun makes an appearance and I'm happy with temp settings compared to reality of thermal gun readings I'll run it in longterm. Got some sticky back velcro that should hold the probe in place and insulate to keep reasonably accurate.
The automated cooling system (OOHHH!) is powered off the home stack batteries from the 2kW back up DC/AC inverter which keeps me covered on the remote chance that we see a grid failure. The Solaredge system will shutdown while the Victron keeps powering the batteries. The switch is £11.88 from Ebay. Rated to 13A, would be a simple way to automate a heater as it also has timer functions.
Simple yet effective.
Cost to automate cooling of all generation units?
Temp controlled switch £11.88
USB hub £10.99
4 of 50mm fans £7.99
Total £30.86
On my unexpected 70W Victron production gain we'd need 14.285 hours running time at peak to achieve 1kW extra. Being brutal at the IO price of 7p per kWh i'd need 6,297 hours peak running hours to pay back the system.
That's 1,259 days if we could see a 5 hour window of Victron peak per day. Guessing at 100 days per year here when that is achievable i'll only need 12.59 years to get the cash back!
Day 1 and its grey skies and rain here.
Edit-Tested at lower temperatures as demanded by the day. All good, kicks in and out with temperatures dropping quickly. Looking forward to seeing it operate at 3.2kW soon.

Re: Small things matter
The sun has not broken through once today. Came close twice but nope. Reverted to Winter cooking style on WBS, chicken, prawn & cashew balti curry with all rice Water wbs heated too.
No grid touch but closer than I'd like.
How the rest of u doing?

Re: Small things matter
We still managed 23+kWh's generation and that got the whole job done but nothing for the EV today. Odd in July. Great to see that the system can get it done in poor to weather. There was much dishwasher and multiple washing machine cycles plus a few into the HWT too.

Yeah, spent the afternoon torquing up connections on the Victron gear and making up CAN cables.
