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.

@@Patrick-ni3xy Turn off the inverter by disconnecting it from the grid and turn off DC-switch.

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)

Shouldn’t those exterior cables have drip loops ?

Also stops the array being a massive induction loop. I'm fairly sure the IET solar code of practice recommends keeping both legs of the string no more than 10cm apart.

Yes a insulated cabinet so in winter batteries stay warmer. I have my setup in my basement where it stays around 60F all year.

That outdoor AC isolator contravenes BS7671, the 20mm galv couplings are not water proof and are mounted beneath the 50mm trunking. This will allow water to ingress not only through the couplings, but also through the trunking when it fills with rain water too.

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

Well done all the team you did very great job and I like your aducation and inspiration to all men out there one of them my self as an electrician.

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.

Good work, but there must be a neater solutions to hide the ac / dc isolator and fuse board, I would not like that on the side of my house.

I have 12 x 320 watt solar panels connected straight into my 5.5kW inverter in my garage with 8 x 6v 229 Ah batteries also connected to my inverter which is connected to my consumer unit to supply my house electrics with a mains isolater switch and I don't have any of these electrical gadgets they have connected up and it has working fine for over a year now.

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

Make sure there is no load then you can disconnect I would normally disconnect in the middle of the string then disconnect panels as you like

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.

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.

What is the W of the panels and how big mm2 is the cable? in Sweden you can have 16p 415w panels on a 6mm2 cable. And a mc4 should be ok to disconnect if there is no load on the string of panels, If there is load you will get the nice free energy in the body and it hurts (i know how it feels :D)

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.
