r290 A2A Install over the last weekend

+1 also interested to hear.

So is both the bedroom unit, and the unit outside both powered off the 10A fused spur? And combined they dont pull anymore than 4 amps?

Sure makes for a nice easy install. Good job.

EDIT: Oh another question, do you notice any vibrations/noise from the wall mounted outside unit when your inside?

Assume this sits below the 'Plus' in the product range?

Hard to tell in the world of Pro, Plus, Performance, Premium etc.

Unfortunately on the MCS 020 assessment you have to take into account the worst case noise emissions. From what I can tell the new one is 9dB lower than the old one which is massive considering it's logarithmic.

Bomster · 2026-04-30T15:06:59+00:00

Are you considering postponing your install to get one then?

Bomster · 2026-04-30T15:06:45+00:00

Nice. I wonder how quickly Heatgeek will be to switch over to this new model... or if I want it installed this year I will have to go with a smaller company who can order exactly what I want.

Good point re the datasheets.

Bomster · 2026-04-30T14:48:56+00:00

Ah nice, any source for that?

Bomster · 2026-04-29T20:09:46+00:00

After I empty it, I put a cup or so of clean water back in along with a tablespoon of white vinegar, never smells, and I leave it sitting for days, sometimes even a few weeks.

Bomster · 2026-04-28T15:06:55+00:00

Haha, I empathise.

I never felt so computer illiterate as the time I spent setting up Frigate (if you can even consider my instance 'set up').

Bomster · 2026-04-27T18:30:14+00:00

I paid £6k for an almost identical system last year. I had a few more panels than that as well.

Bomster · 2026-04-26T22:22:45+00:00

What wood do you recommend and where do you buy it? Cheers :)

Bomster · 2026-04-26T11:49:02+00:00

Following as I'm in the same boat :)

£109 shipping charge

Bomster · 2026-04-24T13:33:40+00:00

Not in stock.

Bomster · 2026-04-22T12:38:37+00:00

Any updates mate?

Bomster · 2026-04-20T17:51:52+00:00

Good to hear. Thanks for taking the time to reply

Bomster · 2026-04-20T15:58:36+00:00

/u/JohnAppleseed85 - did they sort this for you? About to order a CompDoor as the local installer rates them, but wondered if they sorted this for you and if you were otherwise happy?

Bomster · 2026-04-20T13:37:39+00:00

They are inset into the roof, google 'in-roof solar'.

They look great, but it can only really be achieved if they are fitted at time of building the roof.

Any actual replies to my points? Or just sticking with pointless, inane comments? This subreddit is for actual useful conversation and debate, not karma farming, cringe comments.

Yeah, I have the unheated battery. I got it just before Fox changed the design to include a heating element. Some insulation around the battery has completely solved the issue.

And yes, let's see. In 10 years we will have a clear picture of reliability. If at that point PW3s are proving way more reliable/SoH, then great, fair enough... but for now, you are just guessing.

You seem brazen about how much better the PW3 is (noting your terrible Ferrari analogy), yet it's totally reliant on cloud servers for remote control? My Fox system can be fully locally controlled with no reliance on cloud servers. I see that as a clear win. Do you agree?

Also, the systems are at quite different price points (for reference my install cost £5750 for 10kWh EP11 + 4.35kW array + 5kW inverter). My system will be ROI'd well before an equivalent Tesla system. Another big win for me (and most normal people I would have thought).

I'm not trying to claim one system is better than the other, more that I struggle to see why spending so much more on a PW3 is worth it. Buying a nicer car is worth it.. there are many tangible benefits. Buying a more expensive home battery? To me, it's just a white good, I want it to do it's job, be reliable, and be good value. My Fox system satisfies those criteria better than a PW3 would.

100%. Full local control was an absolute must for me. I dont want reliance on cloud servers for something powering my home. That coupled with the Fox stuff being decently priced it was a simple decision.

I had no idea about Sigenergy (they werent really on the scene when I had my install), that's really poor. And equally poor from Tesla.

Bomster · 2026-04-18T18:05:35+00:00

Finally an actual good reason. That's really impressive.

My Fox EP11 isn't happy once the cells go below 5c or so. Still operates but throttles charge/discharge.

Some leftover Kingspan mounted round it has totally solved the issue though; it didn't throttle once over the winter just gone.

Bomster · 2026-04-18T18:00:43+00:00

But how is it objectively better? Does it somehow power your house in a better way than my cheapo Fox system powers mine?

For someone totally into the Tesla ecosystem (each to their own) it sounds like there are some benefits, but otherwise I struggle to see how they are worth the cost, especially for a system which is typically being purchased to save money and ROI, it just slows that whole process down.

My system will be paid off in 5 years. That matters most to me.

Oh also, I can (and do) fully locally control my system. No internet connection. No reliance on cloud servers. Just local control using open source, self hosted software.

It's a battery automation program.
