Forced To Change Our Own Solar Install!
Рет қаралды 167,657
Жыл бұрынHave you ever got to the end of a job and then realised... that it isn't actually the end of the job? In this video, the artisan team headed up by Jordan, made a discovery which impacted the entire job. In other news, John contemplates wearing a "work kilt", Artisan's solar panel cleaning service got some more work done and almost the entire artisan team makes an appearance. Settle in for this week's fix of Artisan Electrics.

Agreed - I'm also not sure I'd appreciate having all of my isolators available for anyone to play around with after a quick hop over the fence. I hope the Libbi is also better than the Zappi and Eddi, because I've had both for nearly five year while they are a good idea, they are rather poorly implemented. Just ditched the Zappi after I went for a different battery solution. They 'just about' work, but everything about them is just OK and you spend most of your time coming up against things they can't do or can't do very well.

You are correct that the MC4's could arc if disconnected @ the MC4, while producing under sunlight and while under load. 'Load' meaning a closed circuit i.e. with the inverter/MPPT. If the panels are all connected in a string but disconnected from a load, it is safe to disconnect them. In fact, I like to break the string if I'm working near both ends of the string with full voltage on them. Treat the string as a battery pack with corresponding voltage. Cut the string in half if you want no risk of arcing or shock (especially if you're wet with sweat and handing both of the MC4 connectors)

Nice move when working with live panels or making off live dc cables to use insulated gloves, although the panel connectors are fully shrouded it could easily be contaminated with water or …other contaminants.

At my place code requires that dc conductors for bateries (and other unprotected sources) should be separated at least 30 cm (by old regulations, new is comething less, not sure how much) if not protected by fuse or circuit breaker (not switch, breaker as breaking short circuit currents). Putting wires in same pipe from solar panel would be a big no no at my place, but watching various clips from around the world, it seems that only we have that regulation. This is a real pain when doing batery wiring for transformer stations and similar (110VDC) where bateries need to have separate room also (naturaly vented). Nice work, love the videos. Best Regards

Unplugging should be safe, if and only if you don't have a complete circuit, because then there is current flow, but you'll have a potential difference, between the MC4 connectors in this case. If there is a short, in this case without the inverter, then there most likely will be a massive current flowing in the circuit. For how long, depends on multitude of things, internal resistance, protective elements etc.

18:58 shouldn't this be independent instead of parallel? I believe it should as that tells both MPPT's to work independent from each other. In fact using the parallel settings would have allowed you to not change the roof layout and just use Y-splitters to use both mppt-trackers as one for one string. But libbi manual and forum isn't clear about this. Other inverters work like this though

When did the DC surge protector rule come in? My system doesnt have them, it was installed in August 2022?
@rdstewart14 Жыл бұрын
I had solar installed this month with no DC surge protection - only AC surge protection. My understanding is -: Section 712 We also have some changes to section 712, with respects to surge protection. Regulation 712.443.101 states that where protection against transient overvoltage is required by section 443, such protection shall also be applied to the DC side of the PV installation. This will mean that if the electrical installation requires surge protection to be fitted to comply with section 443, as discussed above, SPDs would now also need to be installed on the DC side of the installation to protect both the PV panels and the inverter. When the inverter incorporates an SPD, it is only considered as fulfilling the SPD requirement if the manufacturer specifies its use for the DC side of the PV installation, otherwise, it will need an external SPD. Varistors included in the inverter are not considered an SPD. Surge protection devices designed for the use on the DC side of a PV system are designed to a different standard than SPDs used in low voltage installations. Although they are still described by using type 1 and type 2, as explained above, where type 1 devices are to protect against direct lightning, it is extremely important that only devices designed for use on the DC side of a PV installation are used. All SPD’s installed on the DC side of a PV installation shall comply with BS EN 61643-31.

Nothing protects against a direct lightning strike - it blows everything around it to shreds. The whole concept of a surge arrestor, of the types mentioned, protecting against direct lightning is, IMHO, absurd. I have seen the effects of direct strikes on remote radio installations - not pretty.

You sure that cable is RS485 / Belden data cable @ 16:07 I can't see any sign of a foil screen/drain wire and it doesn't look like a twisted pair. Cable looks like standard control cable which is definitely not suitable for RS485 data connections which should be screened (especially since they are running along side 230v cables) and be a twisted pair for correct impedance matching and common mode interference suppression via differential signalling.

You might be right there, but it's hard to tell without seeing it being stripped back. It's not great but if it's only going a few metres from the inside control box through the wall to the inverter, it probably won't matter too much.

If you're ever in doubt about the safety of disconnecting PV DC under load, there is an extremely simple solution: Drape a dust sheet or tarpaulin over the panels whilst you disconnect them. If they can't see the sun they can't hurt you. In general, whether it's safe or not varies greatly, with only 8 panels you should be fine as the peak voltage won't be too high. With long strings you have to be very careful.

Which inverters do you know of that have surge protection built in? SolarEdge three phase inverters have it but not single phase ones. Check the latest version of BS7671 under section 712: This section specifically addresses solar PV systems. Regulation 712.443.101 states that where protection against transient overvoltage is required by section 443, such protection shall also be applied to the DC side of the PV installation. This means that if the electrical installation requires surge protection to comply with section 443, SPDs would also need to be installed on the DC side of the solar PV installation to protect both the PV panels and the inverter.

Thanks for responding, Lux power and Fox-ess have single phase units with SPD protection stated on the data-sheet. Also spoke to the technical team at Alpha ESS where they were not under the impression it was required, although that was a commercial three-phase system. This is useful to know though thank you. Main reason I ask is that I have never seen or installed them myself. There is some grey area for me if the protection was provided through software as that should not be relied on but manufacturers instructions takes precedence over regs. Guess you can never be too careful with providing enough protection for these systems as if something does go wrong it would be very difficult to not be liable the way the regs are structured. If in doubt get conformation form the manufacturer I guess. Having moved into the industry this year I am happy to rely on others designs currently but want to make sure I'm getting it right for my own installs in the future. It seems there is still a lot to be ironed out though in the industry. Your content is very useful!

How about inverter startup voltage. Before change there was 10 panels in series and if the inverter startup voltage is 80 volts then inverter starts when one panel voltage is 8 volts. After change there is only 5 panels in series and the panel voltage for one panel should be 16 volts that inverter starts? Does this affect to electricity production - is the production lower when there is not direct sunlight?
@philpem Жыл бұрын
Any solar panel really needs direct sunlight to work correctly. Indirect sunlight or diffused light (cloudy day) will massively reduce power output. For instance, with two 545W panels on a perfectly clear day, I've had nearly 1kW output. On a cloudy day, more like 200W. The open circuit voltage doesn't really matter, as the panels won't be generating a useful amount of power until the voltage is about half-way to the normal full-sun output voltage.
