Am I the only person who thinks it looks just like a chest freezer? But Kudos for the trendy looking wall mounted water butt to the left.

It is a lot bigger in real life than it seems from the website that's true.

It was more the type of plastic used that got my attention. Their web site images indicate a matt finish, while your photo indicates a gloss/reflective finish. The result I guess would be something that looks a lot like an out of place 70's piece of furniture when placed inside a home.

I certainly wouldn't want it in the house, i said previously that i preferred the white goods look of the previous model but its fine hiding in the garage quietly shaking its stuff in the background.

Hi


Quote
Thats where the fun started, they no longer produce the PowerVault 2 and carried no spares to fix it, they did offer to replace it with a PowerVault 3 but they only come in 4, 8 or larger capacities, so the options given were to drop down to a 4Kwh and they would replace it with a PV3 system or pay extra for another 2Kwh expansion and they would replace my PV2 with an 8Kwh PV3 system, that is almost the option i went for, in fact i have asked them to upgrade TO the 12Kwh system (cost an extra 500) so that i can expand it to 12Kwh in the future if i wish too.


Well I am now in that position!!

G200 installed May 2018

Started having issues with batteries loosing capacity and they were changed Feb 2019. The cells go out of balance and I have been told they use passive balancing which obviously doesn't work.

Replacement batteries are now out of balance and therefore have lower capacity.

They have offered me a Powervault 3 as a replacement but don't seem to have allowed much against the old G200 unit!

When the scheme started we were offered the Pv3 but with the second life batteries for the same price. I decided on the 200 as it has the emergency outlet and the 3 did not.

I seem to have the option of keeping the G200 and have replacement batteries every 6 months or pay more money to "Upgrade" to the Pv3.
Think I will have to have a chat with them.

Not too happy at present.
Apparently the Pv3 has active cell balancing so the batteries should not be an issue.

They shouldnt be allowing you anything against a new system, they should be fixing it, or replacing it with a like for like system.

PM sent though

Yeah that doesn't sound right at all - if the G200 batteries are already failing after replacement just 6 months ago, they should be replacing the whole unit like with like, not expecting you to pay the difference, or indeed offer you a full refund.  Sales of Goods Act, Statutory Rights and all that.

Hi
Thanks for the replies. My thoughts exactly. Just putting together an email to them in slow time.

Hi
Bit of an update.
After many emails,
I was offered an Eco 3(second life batteries) as a replacement. This normally comes with a 3 year warranty but after a couple of emails the warranty would be increased to 5 years. The downside of this offer is this unit does not have the emergency outlet and my existing remaining warranty of 8 1/2 years would reduce to 5 years.

They said if I wanted a new unit (Powervault 3) with a 10 year warranty, I could have it at the same reduced price as their EDF offer and they would take my unit away free of charge!

I have been pushing for a replacement with my remaining warranty being honoured. This has not happened.

At the moment I have decided to stay with the G200 due to the warranty and emergency outlet issues. They are now trying to find replacement batteries for me. As I am now requiring a second replacement in just over a year I would have thought it would become quite expensive for them to keep replacing the battery units.
They go back to their factory and the cells are rebalanced and then reused on another unit, I believe.
Basically the G200 does not have a BMS fitted. I imagine it is because the unit evolved from a lead acid battery unit and didn't need one with those batteries.
I was told the 3 and Eco 3 do have a BMS with an active balance regime.

I have been told that they don't get many of the batteries on these G200 units going out of balance. I wonder if it is purely an issue that the owner doesn't know??
I fitted an import export meter to mine and did a load test to prove it.
They also can remotely check the cell voltages to confirm.
Also in one of the letters they did say there is a possibility they could look at some type of BMS for these G200 units if time and money are available. Would be nice but not holding my breath.
Again on mine it is one battery that has gone out of balance. Not sure if it is the one in the same position as previously.(as in Primary or secondary)
I am fairly sure the defective battery is dragging my unit down to about 1 kWh at the moment.
It would be a great outcome if they could add a BMS to these units as I do think that otherwise the are really good especially with the emergency outlet.
With the 3 and eco3 they did say there wasn't much call for a unit with the facility for emergency power which I do find strange.

Will keep you updated.

First post but long time watcher!
Had my G200 since 2017 and have been through 4 sets of batteries, all seem to go out of balance over time, been offered P3 eco upgrade as no new replacement Lithium-Ion (LiFePO4) batteries just old re balanced ones, this latest problem has been going on since August, customer service has been really poor, seems like we are not alone, still waiting on an install date

Welcome, that's quite some first post!
My G200 has had 1 set of batteries replaced, mine is a 4kW lead acid one, but the current set seem to be doing much better.  Good luck getting the unit replaced. The P3 is a completely different size and shape to the G200, do you have somewhere to put it?
