Powerwall versus Givenergy batteries

[94jdh]

Am I addicted and taken it too far, monitoring on the go?.....

How have the folks waiting for First4Solar faired, it would seem like @94jdh has completed, how was the installation? Has @spon88 had your installation yet ?

They finally came back to me suggesting they will give me a quote this time, are they an acceptable cheaper service? Other installers round here are charging well over the odds.

I am also considering getting on the solar + battery bandwagon.

Prices seem to have risen considerably since this thread started but that's probably just life.

What does the hive mind think of circa 12.5GBP for 4KW of solar and about 10kWh of storage in the South East?

Any recommendations on installers would be appreciated.

That price is about correct, installed.

I've just been quoted 21K for the same, so I would suggest yours is a realistic price. No one round here wants the work.

Hi,
Yes completed to a degree - I currently have two Gen1 inverters installed until availability of the gen2 with a 2k retainer.
Install was a lot longer than they thought - which from my understanding was blamed on the survey. Everything is working well ( as it should do) and having the two batteries is definitely the right direction ( may go with more I the future) - saving this month alone being over £160.00 - spon88 hasn't yet got there, and their are some issues with State of Charge with the batteries over on official Givenergy forums.
However, we don't yet know the extent of this and what percentage of installs are affected - apparently this will be fixed with a firmware update, but many aren't convinced as it's been worked on for nearly a year.
The installation team were great, the communications were shocking and hard work to get the installation over the line, which obviously isn't ideal especially with no-shows and wasted holidays.
This finally was resolved with some compensation which I've been happy with - I just hope that the last part of gen2 swapping is planned better.

This is exactly what I've just paid for 4kw with 13.5kwh of storage. Seems about right at current prices

I’m about the same for 6.4 kW solar and 9.5 kWh storage. Slightly less if it was all on one roof, but I need an east/west setup so additional scaffolding costs take it a little over £12.5k.

I paid 12k in September for a S & W 6.8KW split, GivEnergy Gen 1 5Kwh inverter & 9.5KWh batt. Very pleased with the system.

As another option for those trying to source batteries - worth on having a look over Solax hybrid inverter+battery combos.

17.5kWh storage + 5kWh (6000watt peak) on the inverter, for £9-10k with install.

My install is due for 12th December after four cancellations, so not great. The price is great and it seems that the installation teams are good, but the organisation and comms have been poor.

That said, a lot of it is due to Givenergy failing to supply to agreed leadtimes. A frustrating journey for sure but I'm hanging in there.

What is perhaps more concerning is that Givenergy have some significant issues with management of state-of-charge of the batteries which is becoming more prevalent. The "fix" has been in the pipeline for months but so far it hasn't worked.

If I was starting again, I'd probably look elsewhere to be fair, but given the excellent price and "imminent" install I'm going to hang on and run with it. Cancelling now would mean a huge price hike and back of the queue.
