Many thanks for this video. Am looking at adding an AC coupled battery to my exisiting Enphase PV solution. Probably late now, but you could have saved teh coinduit by having the data cable enter with the battery cables and then loop out of one of the spare compression glands.
Hi, It is very educational, and learned a lot. I have a small question. I have GIV-HY-5.0 G3 inverter and a Gem120CTM meter. But not able to commission it. Potal not seeing the meter. Use ports 9 and 10 on the meter and the meter port on the inverter is correct. (+ & - are correct on both ends of the cable.) there is output on this twisted cable. But the system not seeing the meter. The meter displays all data such as voltage, download power, current, frequency, and so on. Maybe I require an EM115 meter !!! thanks
Hi you said there it’s not possible to extend the ct cable length, is it not possible with Belen ? Is the only option the Dora things, they are soo expensive 😔
18:13 great video, just on your calculations here I think you’ve been a little simplistic, as I imagine a good chunk of that grid to home usage is also in the Go period going to the EV as well as the battery which the charts don’t show
Hi mate, thanks for the comment. Could you elaborate further? I'm just doing a very rough calc based on what the battery is saving them- they already had an EV and the go tariff before this install. Thanks, Tom
@@HeritageElectricalno worries, the two options it shows is grid to home and grid to battery. Assuming they have the battery set to only charge during the Go 4 hour window, any EV charging at the same time will be counted as Grid to Home but would be at the cheaper 12p rate plus any other devices they may run on delay, we manage to do washing, tumble drying and dishwashing in our 5 hour go faster window, which more conveniently starts at 9:30pm so I can do a 1 hour wash and load it in the dryer before I head to bed). We don’t have a battery yet but if I look at my Octopus bill at the moment 45-50% of all my usage is in that cheaper window. Which makes the cost per month calculation a little more complex than applying one figure to the grid to home kWh
Different question . Is there way to pair DIY LiFePo4 48V 16s with Givenergy 3.6kWh hybrid inverter ? Or it need to be specific battery with communication cable only ? Thank you
You would need to consult with Givenergy I reckon. Personally I would match manufacture of inverter to manufacturer of battery - you may have issues if you need to make a warranty claim otherwise.
Hi Ian, thanks for the question. I spoke with Givenergy who informed me that when the house load changes say from 1000W down to 500W, the battery by design has to ramp down the discharge resulting in a small amount of power being fed back to the grid for a few minutes.
Apart from your calculations re payback being highly flawed as mentioned in an earlier comment, I'm concerned about the lack of space given to the inverter. The spec notes that the inverter should have 300mm clearance below it, and 400mm to the left, right and above. Clearly in this installation only the bottom clearance meets the spec., I'd be concerned that in the event of a warranty claim that GE would refuse any claim on the basis that the inverter wasn't installed correctly. Not having a go here, but if this should happen, you're going to end up with the bill! I've only watched your videos as I'm about to look for tenders to fit mine, so wanted to see what it entails.
Hi Will, this clearance was checked directly with Givenergy before install. The Givenergy commissioning process is very thorough and involves sending photos to ensure compliance with installation to validate warranties etc. Empirically the customer was saving around £3-3.50 a day based on previous vs current bills with the battery install - this video is designed to be a quick look at some of the information provided by the app. If the customer was looking for detailed analysis before deciding to make a purchase, we would have done the calculations more thoroughly and employed an energy meter to determine usage/spec suitable equipment. As it happens this customer already had done their calcs and purchased the gear, we were asked to fit and commission only. Thanks for the comment.

Ordered my gen 2 5.0 inverter today along with the gen 2 9.5 battery. 👍 doing the course in a couple of week to
Did you do the course
@@nosh121081 funny enough i did the standard installer course months back but yesterday I did the training for the new all in one

Why the ‘leakage’ from the battery back to the grid?
