[@VIEWEROFVIDEO1]

Great video as I am considering pretty much this exact config. The gateway is my sticking point tho. From what I can tell it is really only providing a UPS type feature if I am correct. We can still feed back to the grid without it. In the video it sound like there is a humm out of it when it is on the grid. That might affect where I would be putting it TBH.

[@electrician247]

Yes the gateway is just for backup purposes and bringing multiple generators into that system. You don’t need it just to use the system both for storage and import/export. It does humm a little as all contactors do Thanks Mark

[@protectiongeek]

A nice looking bit of kit, Mark. One or two things I noted during the install - design issues, not installer issues 🙂 - the AC power connector to the inverter doesn't give much room for the bend in the AC cable. Maybe the manufacturer should have a right-angled terminal connector as an option to make the electrician's life a wee bit easier! Secondly, the finished outdoor unit is very smart but I think I would be fitting some kind of mesh to close-off the gap at the back of the unit to prevent rodent damage to cables or wasp nests. The changeover contactor has to be break-before-make, of course, and so there is no guarantee that any equipment like routers or desktop PCs will not 'see' the grid drop out. I would always advise the use of UPS for these devices. The minimum delay before back-sync and automatic reconnection to the grid from island mode required by G99 is 20s (clause 10.3.4). I would say it should be a minimum of 60s if the installation is supplied from an overhead MV distribution network to allow any auto-reclosing equipment on the overhead feeder to have finished its sequence. Finally, I'm a bit wary of the use of a C125 incoming MCCB(?). Installations in rural areas supplied from pole-mounted transformers can have surprisingly low prospective fault currents, so a busbar fault in the gateway might not be cleared! Thanks for another very detailed and informative video.

[@electrician247]

Thanks! The connector space is pretty roomy tbh behind the cover panel. Perhaps deceptive on the video. But as an installer more than happy with wiring room at the inverter and gateway. Enclosure around cables is always a battle outdoors. That said rodents and wasps will find a way past most barriers. Absolutely correct this is not UPS but the time is in the milli seconds. We have tried this on multiple similar solutions from other manufacturers. Most past the router and PC test tbf to them. Which is incredible really. In terms of the OCPD we need to remember we are protecting faults within the installation. Those are selected based on design considerations. It can not be expected of manufacturers to provide a one size fits all. In the circumstances you describe the breakers can if required be changed. That said much like main tails into a regular consumer unit the service fuse is always a final catch all in terms of short circuit in the main switchgear. Luckily here we have plenty of fault current. Thanks for watching.

Am I understanding correctly that the battery stands outdoors? So it is not only exposed to rain and moisture but also to the cold during the winter. I have heard that it is not good to keep batteries in the cold regardless of whether it is indoors or outdoors?

These are IP66 and rated for outdoor environments. PAS dictates all batteries should be ideally situated outdoors. We try when possible to site them in garage areas.

[@KevinPratt-r6l]

Hi great informative video. The product looks good but just wondered about RCD protection on cable supplying inverter outside. There is obviously no RCD protection from the gateway, I presume meaning cable would have to be run in containment or clipped direct the whole route, unless SWA used? Our last MCS inspection, the inspector required RCD protection if the system was installed outdoors no matter the cable type or installation method. This was also required to be a type B RCD. What are your thoughts on this Mark?

[@electrician247]

I would always encourage RCD protection for outdoor equipment but technically I make your MCS assessor wrong. The regulations are not what our opinions would like lol. If your cable installation method doesn't require RCD protection and the equipment connected on the end of it doesn't. Well then it doesn't lol. In terms of the type of RCD protection used that would depend on the inverter. Some will leak beyond the 6mA RDDC values a type A can cope with so type B would be required. If an MCS assessor made that argument towards myself it would be a fun one to bat around a bit with them lol. But often easier to do what they ask for lol. All that said you can configure various setups in the gateway. We have done that recently with 2 pole rcbos for EVSE chargers wired direct from the gateway. So you can install whatever you need really.

[@js64984]

Great video but no TT earth installed?

[@davidianwalsh]

The obvious question is how does the cost compare to the Tesla PW and The GIvEnergy All-in -One?

It is lower cost than both. But price is all much of a muchness tbh. Value is key and pound for pound this is right up there with the GE AIO.

[@IanB61]

With the GE you'll need a solar inverter as well as isolators. Correct me if I'm wrong but this is all included so looks cheaper than the All in 1 and imo a much neater solution I.e less wires and trunking on show

Great product. Just wondering about the warranty. This is throughput based , 23.7Mwh for a 8Kwh battery or 10 years to 70%. Too little for trading energy. And for charging cars. Do I miss the point...

[@electrician247]

Sort of missed the point yes. The batteries are not really intended for charging cars/vans etc. They can be utilised in that way but as identified you would be putting them under more use/strain. Most consumers want to utilise that energy in the home. Trading energy is perfectly possible with the combined approach SigEnergy offer. solar, V2H/V2G and battery combo.

[@easyyards3154]

Another great video Mark. 1) You said a peak of 9000w from the battery in backup (off-grid) mode? The data sheet says 10 seconds. So does it take up to 10 seconds to be able to supply 9000w? Or can it supply up to 9000w peak for 10 seconds? 2) Would the discharge rate be limited by the 6 Kw inverter? Two 8Kw batteries could theoretically discharge 4Kw each, totalling 8Kw but the actual AC discharge limited to 6Kw by the inverter. 3) As the batteries are DC coupled could two 8Kw batteries charge directly from solar panels at 4Kw each simultaneously, or again, are you limited by the 6Kw inverter? So one battery charging at 100% rate (4Kw) and the second at 50% rate (2Kw), or split to both at 3Kw each? Thanks in advance for your answers.

[@electrician247]

1. 10s peak 9kW 2. The inverter would limit the AC output but not the DC power to an electric vehicle on the DC charger. They now have up to 12kW single phase inverters available this used to be the biggest, no more! 3. Yes DC from the panels can go direct to the batteries. It has a hybrid capability for both ac and dc coupling.

Your passion for your work, industry and solar is evident and highlighted by all of the replies to the comments for all of your videos, very commendable 👏🏻 Could I ask a supplementary question 🫣 1) Does the gateway require any form of DNO permission or notification? I thought that some DNO’s are “uncomfortable” with systems that “island,” but can feed back. Is this system the advancement of this? I think you said the contactor will immediately “break” up on detection of power loss from the grid, thus preventing any back feed. Therefore, are the DNO’s accepting of that?

Hi, Looking at installing an me of these , can I ask. I’m assuming the property has a fully RCD protected CU bit how is the inverter protected in the event of a loss of supply & potentially the DNO supplied earth. Many thanks Mike

[@electrician247]

The gateway has a port for an earth for island mode should you wish to use it independently to the dno earth. However current guidance is to maintain both together in all states. The inverter is the source when loss of supply occurs. It's a clever setup that can function as a hybrid and AC or DC coupled battery stack. Game changer.

[@prosolar7889]

@ Hi, Thanks for the reply , yes I understand that aspect of it , but I can’t see and RCD protection in the gateway (unless it’s done by the comms box, similar to the OPEN devices in EV chargers. I’ve installed GivEnergy which has a RCD protecting the PV inverter & AIO battery side & When I do the Tesla’s I fit it with a RCBO. It looks a great setup & the output rating for the 12kw are 👌 for a high demand property.

[@electrician247]

@prosolar7889 we fit a lot of givenergy aio systems and the rcds present a lot of problems on older FIT inverters lol. Off grid the source becomes the PV/AIO/SIG so as long as your final circuits are RCD protected for fault and additional protection your golden. Unless the circuits leading from the AIO or PV are buried in the fabric of the building. Then you might want to consider close to the source if you are not happy to rely on built in ones on the PV or Battery. Whatever is in the gateway doesn't help with that though. These are customisable same as the givenergy and tesla stuff. You can change and request different setups. We have done that when feeding EV from the gateway for example. All in the design

[@Elementum_Renewables]

So in this installation you didn't install RCD protection on the backup supply?

[@electrician247]

@Elementum_Renewables the backup supply is the sigenstor so what would the RCD be protecting. Surprising comment as this is not a complicated setup. If the final circuits lack rcd protection its a consideration in the gateway but then imho it's very poor design in terms of division of circuits. Hope that helps. Most of the main brands have some excellent training on this and you might find BS7671 and the EESS cop useful in terms of configuration during island mode states
