Great looking installation. I guess the grid meter needs to communicate with the inverter, and if so how? I never seen a cable at the inverter, like a cat 5 or rs485. Thanks
Hi, thanks. Yes, your right. It’s the pink cat 5 that you see going into the enclosure with the Em115. It’s tucked away neatly at the inverter side. You only need 2 cores of the cat 5.
Good video, really informative thank you. Why no optimisers, if there's potential shading issues? Was this a customer decision? I'm shortly getting 16 panels fitted to our roof and I've got shading issues later in the day/in the winter so am fitting Tigo optimisers to all 16 panels to make the system as efficient as possible. Is this worth it or not?
Hi , this roof had no shading issues. If you have shading issues you should always use optimisers on the problem area or all panels. We offer optimisers as an option to all our customers, it’s Tigo we use, great optimisers.
For a 5kw hybrid givenergy inverter. What cable would you use from the consumer unit? Would you use? I need 6mm but it says on the installation manuel i need a 4mm earth? Do you use 3 core flex or twin? Do you take an overlay with it?
Hi James. I’m not familiar with an overlay? 6mm twin and earth assuming within volt drop range. We install a 6mm earth wire from battery to inverter for bonding purposes.
What are your favourite hybrid inverters? I have a cabin which has a 16 amp supply. I want to use that supply as essentially a generator for a battery, and some pass through. I have been looking at victron and Solar so far.
@@ereselectrical9397 Thanks for the response. If the generator was a hybrid, and you had amble battery storage, why would the supply be an issue? Essentially its off grid, but has an AC connection for some help charging over winter or when demand is higher than the hybrid inverter (7.5kw Sola g4)
@@DaveDaveAlanAlan hi. It’s not off grid as it has an AC grid connection. For a 3.68 KW Inverter we run a separate 20 amp supply in 4mm cable. You need to keep volt drop under 1%. 3.68 is roughly 15 amps. If you were force charging it would draw around that 15 amps plus anything else on the sub circuit. 7.5 Kw’s is around 32 amps.
@@ereselectrical9397 Is there a way to limit the AC input? I need to double check, but I think the supply is 32amp not 16, in which case I might be OK, but need to check. Thanks for sharing your knowledge.
@@ereselectrical9397 thank you for replying. Is that because customers aren’t aware of it or don’t have a need for it? Do you know the specs of the EPS in terms of load it can cope with. I’m considering it.
@@nathanm5388 mainly due to the cost of it, very expensive. If you are rural with a lot of power cuts fair enough but for most it’s not a big requirement due to stable grid. We see a lot of lethal EPS installs, from an installer’s perspective you have to be very careful to install it properly. Same discharge rates to the best of my knowledge.
Good question. It’s normal to oversize an array. The reality is, it’s not often you will get near 100% efficiency out of your array, a lot has to align for that, irradiance, temperature, sun angle. Oversizing the array allows if to work harder when conditions are not so good. The inverter will utilise more than 3.6kw’s if it can use some of that power to charge the battery. Lastly, a 5kw system required full G99 DNO approval, in my opinion, that’s to be avoided unless you are a bigger than average electric consumer.
OOI What is your reasoning for using the Hybrid system over a AC coupled system? It (as a user) has a tonne of down sides (No external monitoring of Battery and Solar usage as seperate entities, coupled systems, limited max power output) all for what seems to be a fairly small cost saving in the grand scheme of things
You can monitor PV and storage separately, every inverter has max output regardless of type. The hybrid has a higher charge and discharge rate than the AC equivalent with the manufacturer on this video. Twin inverters equals more cost plus more chance of one going wrong. One inverter also saves space. For most people a hybrid is the way to go. I accept for high consumers a grid tied plus one of even two AC coupled make sense. If you think AC Is for you , crack on 👍🏼
A very neat installation and interesting to see it being built.
Cheers 👍🏼
Nice job! I install solar panels myself in Ireland, nice to see how other installers do it. Subscribed 👍
Cheers Sean 👍🏼

Nail holding the tile ( rare occurrence on new builds in England 😂)

Interesting video! Can I ask why you chose a Type C MCB to feed the inverter?
Cheers. That’s what Givenergy specify.

Hi Dave. I don't have a favourite to be honest. You could struggle with that 16 amp supply. We wouldn't install a 3.68Kw system on that supply.

No.
No, the system can have EPS put we rarely install it.

For knowledge do you utilize Both ac as well as dc loads?
Hi. Not sure I know what you mean by utilize?
Sorry military term
Do you use dc appliances
@@solarindependentutilitysystems 👍🏼. No
Thanks for answering
