The PW also supports a secondary solar panel system connected as AC input, so you can also just extend your existing system with a PW3 and a new solar array or 3 😊
Just a quick question so for me I would want the full 11kw discharge rate as I have a 10.5kw shower , but your saying that the grid decides that for me ? Or you talking about the amount of solar I can send back to the grid ?
He is talking grid. The battery can output max capability to house for your shower. I have 2 x 5kw PW2 so 10kw max supplied to house. You can’t however export 10kw to grid unless you get permission for that value.
@paulnextlevelbusiness2257 Do you mean the frid wont let you dump 10kw in one hour, but you could for example drain the battery over three hours at 3.3kw?
@@andy9841 yes, depending on what export approval you have the unit gets configured to stay within that limit. Limits vary hugely between locations as grid quality varies, most people get 3-6kwh export limit range, our area seems good so we got 17!
Hi, thanks for your comment. Grid approval is generally broken down in to two parts. Demand (charge rate) and export (energy sent to the grid). We'll apply for the full 11.04KW for both and see what comes back, they may allow 11KW demand & 11KW export, or 11kw demand and say 5KW export. Sometimes they'll only approve a lower demand too. We're very experienced with all of the DNO's. Feel free to have a chat with one of the team for any advice :)
Another good video as always! Can you please do a bill comparison video on Efficient boilers vs Hybrid Boiler. I know they always use the cheapest option but just confused as surely gas is always the cheapest option. Needs explaining pleaae. Really looking at getting one but can see no comparable videos
Great video as always. I am currently considering a qoute for a further 18 panels on top of 8 already ordered for the garage. One of your points made in the video is the benefits of start up voltage providing the benifits of micro invertors. My qoute includes a tesla powerwall 3 as well as 18 enphase microinvertors. Why would I need both apart from the ability to monitor each panel individually with the microinverters?
Hi, yes Telsa have stated they'll be near the performance of Enphase (without the optimisation or warranty). We haven't had the opportunity to run any comparison tests yet. We'll share any information as we get it. Did Heatable install your first system?
How well does this integrate with the REA Fusion 2 panels you sell? Can they be added straight to the PW3 or would you still recommend the micro inverters? If you dont need the micro inverters, and I read the installation time is hours less, I'd imagine this would be a good cost saving?
@@andy9841 PW can have almost any panel added direct to it. REA are good panels (we have them plus other non-Rea on another array) for low light and winter conditions, peak summer power not so good but overall year round should win. Microinverters are expensive so PW3 would save money on those but your own shading/orientation etc would determine whether worth while. If no shading issues I would go straight into PW3 and save the £
@paulnextlevelbusiness2257 Thanks for the reply Paul. I guess the only thing I'm missing out on would be the per panel generation stats. No big deal I guess
Hi, thanks for your comment. Paul has nailed the answer here - We can install a PW3 either AC coupled (with micro's) or DC coupled (DC straight into the PW). We have both versions of the REA panel. We got caught off guard with demand but we're expecting 4000 of each type in WC 29/07.
@@Heatable Are you able to make a video showing the pros/cons of the REA Fusion 2 panels on a PowerWall 3 AC coupled (with micro's) vs DC coupled (DC straight into the PW3)? I understand from your other videos the benefits of an AC coupled system (with individual panel solar generation and panel monitoring via the Enphase app being one of them). Do you have any customers that have the the REA Fusion 2 panels and a PW3, that have the panels DC coupled (DC straight into the PW)? I assume you cant mix the two coupling types - ie you can only have one coupling type? Are all 3 strings you mention at 04:13 DC only.
@@StephenPBishop He Stephen, thanks for your comment. We have a video planned although we don't expect this to hit the channel for a month or so. We do have a video coming shortly with a DC/AC comp. We don't have any customer with REA - PW3 yet, first one is going in shortly. We got caught a little of guard with our panel stock but 4000 of each are due anytime now.
When you were talking about the pw3 discharge rate and “quote” you can choose your own setting? Is that changeable in the app for the consumer or done on installation day by the installers only.?
Can you install this in a garage that is part of the house? Is there a fire risk or are LPF cells not a problem when regularly charged to full on hot days?
Yes. You can customise your minimum battery charge too for this event. For example, if you were to always use your battery, in the event of a power cut you might not have enough storage to tie you over, so you would programme your battery to never drop below 20%.
Great video, terrific production values. Question please. I have a solar array, from early 2011 with a very high FIT payment level. Can I fit a Powerwall and still receive the same level of FIT? Also could I have another solar array too, even if it needs to be separate from the original and still receive the FIT for the original set up. Sorry for so many questions, but I'd really like a Tesla Powerwall and if possible more solar. But I'd not want to sacrifice the very good FIT I'll receive for another 12 years.
I believe the powerwall 3 can work just like the power wall 2 and soak up excess generation from your existing FIT inverter. You would need to keep your existing inverter so your FIT generation is metered. You could also add additional solar directly to the PV connections on the Powerwall 3. There will be some combined limitations but I suspect it could pick up 5kW from your existing inverter and approximately another 15kW (maybe a little less) from its internal PV connections, which is a lot of power for a 11kWh battery.
Hi, thanks for your comment. The team are really working hard to improve the content. To answer your FIT question - You can only replace the inverter of a FIT system with the same KW rating (PW3 should have a rating suitable). You can add storage, either DC or AC coupled without affecting FIT criteria, you can also charge from the grid on cheap rates. You cannot - increase the size of the inverter that array is coupled too or export battery energy and be paid under SEG. Re the other array, we can fit a microinverter system, then AC couple those to the PW3, this will give the full power benefit and wont affect SEG. Please contact the team if you would like to know more.
Can I add them to my existing PV system that has Enphase IQ8A micro-inverters. My installer says they are not COMPATIBLE. Yet I keep seeing folks say they are.
if the gateway is there.. then why does it have regulations around how much battery varible output you can have? Isnt that the whole idea of the gateway to isolate you from the grid in the first place?
The Gateway is the external interface to the grid. It does not affect the discharge rate to your house, only the level the energy provider will accept back into the grid in your area.
I note there is a Gateway 2 and a Gateway 3. I understand that the latter is simpler / cheaper and can only do whole house backup. But is a Gateway needed at all if you don’t want / need home backup (which is an off grid capability that has an EPS function to deal with power cuts)?
@@Heatable Thanks. I am clarifying a quote I have had for a PowerWall 3 system, which stated that EPS wasn't included. Surely, if a gateway is required (which is what I thought) it must be able to provide EPS, mustn't it?
Does the Powerwall 3 work with 3 phase, it’s a real limitation with Powerwall 2 that only 1 phase is utilised. I’m in Australia and I want the Powerwall however installers are pushing me to BYD as my house is 3 phase. The BYD is terrible for software, doesn’t automatically switch over in power outages, it’s only benefit is it supports each phase
Yes, Tesla Powerwall 3 can support three-phase supplies up to 162 kWh. It has better three-phase support than its predecessor and most other residential battery storage systems, but it doesn't have as much storage capacity as single phase systems.
so is it possible for me with a g98 3.68kwh 10 yr old inverter on FITs able to swap out my inverter and slot this straight in, and increase my current solar pv from 4kwh (250w panels) to the max i can squeeze on my roofs all without any extra paperwork/notifications ???
No as you need a MID registered meter on your FIT generation, so you need to keep your existing meter and inverter, you can use this with the Powerwall 3 though. If you went powerwall 3 you could add some additional solar to it with its PV connections, alongside keeping your legacy (FIT) system.
@@edc1569 Hi Ed, we have installed replacement inverters for FIT clients, retained the gen meter and installed a battery. Inverter sizes had to be as installed. Battery connections allowed. We require the client to seek prior approval before install.

The solar can supply the house first, then any excess goes to the Powerwall (if it has capacity spare) the rest goes to the grid. The max charge limit is rarely going to be an issue for the average UK system.
