Thanks, yes we have used the cloud connect kit a few times. It’s a great system.

Cheers Cam. I agree mate

@@electrician247 The debate/argument regarding DC isolators is down to a few things... Like you pointed out, many DC isolators are designed/recommended to be installed like you showed using 2 linked poles per cable (1 x 4p isolator per string). Numerous rotary isolator ratings are only achieved when using this method & using 1 x 4 pole for 2 strings could pose a potential rating risk on some isolators - rtfm & tbh just use 1 4p isolator for 1 string (linked). IMO isolators are a different kettle of fish, their ratings & arc quenching, actual switching mechanism are second to none - BUT & it is a very very big BUT, they are "cross-wired", pole 1 to pole 2 goes diagonally not vertically straight down like conventional switches, so extreme attention to detail must be used when using high standard IMO's to avoid reversed polarity or dc short The other issue is DC breakers - which are in effect isolators, well the 2p mcb's are sometimes referred to as dc 2p isolation switch/isolator - but these are very different to ROTARY ISOLATORS. Also, these DC breakers (isolators) often need to be wired polarity specifically AND correctly to the input-output/load (again rtfm). Failure to follow the correct wiring of the breaker can/will result in a fire when switching off the string manually or worse a fault tripping the device when nobody is at home. So it is extremely important to understand the potential risk/danger when using incorrectly wired dc breakers > switched dc isolators ^^^^^^ THESE BREAKERS ARE WHERE I BELIEVE A LOT PROBLEMS COME FROM ^^^^^^ The incorrectly DC breaker/isolators faults/fires are lumped together with all the safety stats pointing to risks from using DC isolators = DC isolators are a fire risk for insurance - NOT FAIR to lump proper "dedicated DC ROTARY ISOLATORS" in with DC BREAKER fires/risks (poor wiring/polarity on breaker) I still fit a 4p DC rotary isolator per string - even if inverter has a switch - which the inverter will isolate both strings at once, & not locked in off position, plus we have said how using 2 poles linked per cable = safer max switching capacity. (So a single 4p isolator switching 2 strings = the lower switching capacity rating, could be argued, compared to 2 x individual isolators with links like you installed, plus isolate one string with lock-off when working/diagnosing issues) I strongly suspect that the stats regarding dc isolator fires, insurance companies study, are from mostly DC switched isolators (breakers) NOT dedicated DC ROTARY ISOLATORS !!! Poorly fitted DC "breakers - isolators, ergh nope they're breakers" can/do cause large DC arcs/fires.... DC ISOLATORS ARE BAD, WE (insurance companies) DO NOT RECOMMEND THEM Aaaaannnddd, so the debate/argument rolls on, with muddy waters regarding isolators coz breaker faults are lumped in with all isolators including safely installed "rotary dc isolators" I'm still installing 4p series linked per string rotaries, for ease/safety (lock-off, linked load capacity) Others can continue with the argument, but it just makes sense to properly install them along with the AC one

@@authuruksake969 I’m familiar with the imo isolators lol. They are confusing the first time! Poor connections will be the main driving factor in those fires I suspect. Which imho is why we should focus on improving the skills of those making them. Rather than ditch a vital component.

They are an excellent combo at a slightly lower price point. Both great options.

@@electrician247 cheers. If price were less imp what would you go for as a consumer?

@@dreamz743 either or tbh. If combined with GivEnergy system the PV side is less important imho. Stand alone may sway towards solar edge

Yes mate sure are

Earthing of roof arrays is generally not required unless accessible via Velux windows etc. it can be considered good practice but as with many things is open to debate.

Yes the GE gateway will log your solar generation. You can if you wish also access this via solax cloud but no need for that.

A correctly installed ac and dc isolator represents the exact same danger. None. Let’s solve a problem not remove vital points of isolation for future maintenance electricians and consumers. We can do better. In built isolators on inverters form no part of the fixed wiring and don’t reduce any danger on switching live strings. For the reasons you advocate on the potential quenching distance of DC is the exact reason you want isolation pre the inverter. Same for AC as well. Arcs in AC systems are often overlooked and dismissed but are much more common. The stats speak for themselves on that. Merry Christmas

The answer is it depends… you can use the DNO earth in parallel with your rod at all times. Equally if you wish you can switch out the DNO earth and use just the rod on EPS. Things to ensure is that bonding remains in place in both arrangements and with TNCS the benefit of switching out the earth is kinda pointless if mattalic bonds are in place. We generally have a main earthing terminal outside both consumer units with the supplier earth, rod and bonds then feed earths to each CU from that. You also need to ensure your inverter has a neutral earth bond relay built in. If not you will need to provide one of those for eps mode. This is the work of electricians tbh if you are not one yourself. Thanks

Depends on your specific supply arrangement and local DNO config. No one size fits all sadly.

Nope not a single one

Yes. The rcbo can be upgraded if required also

@@electrician247thanks for this, currently discussing this issue with my installer as I have 2 arrays/inverters but only 1 is linked to the Gateway and I can see the PV output from the 2nd one going straight to grid export via myenergi app, so I’m hoping they can sort this!

@@MCow123 they need to speak to GivEnergy tech support. If your array outputs are beyond 32A the breaker in the gateway will need changing and they need to approve it for warranty etc if that is the case. If the total output is under 32A you are good to connect them in as a collective so long as single phase.

@@electrician247 yeah it’ll need a breaker upgrade for sure so I’ll speak to them. Thanks Mark, love the vids!

Was discussed in the video. Yes in short. Although many optimisers and inverters have them built in now. If you are using them best close to the array. PV shutdown modules are a great place to locate them

Thanks for the reply. Regarding SPD wiring. Is it acceptable to take the earth for an SPD from the consumer unit/MET on a TNCS?

@@user-tf8zx4ge1e you should have a main AC SPD as close to the incoming supply as practical. Then repeat at each sub board as needed. Roughly every 10m into the install.
