GivEnergy 2025 forthcoming batteries and inverters
As a GivEnergy battery and inverter owner, I was interested to discover the attached YT video interview with Paul Landregan, who is GivE's head of product development.
He describes a range of new battery and inverter products that are planned for release in 2025.
Mitsubishi Zubadan 14kW with Mixergy 210l DHW in 220m2 barn property. 24 solar panels = 9kWp with GivEnergy 5.0kW Hybrid inverter and 19kWh GivE batteries. Jaga Strada fan-assisted rads throughout. Landvac vacuum glazing/triple glazed windows.
Highlights which might be significant here are:
There is to be a new All-in-One inverter/battery combo, which is yet un-named.
The battery capacity is to be 13.6kW (from which we can infer that it has 16 cells, rated 280Ah),
and the inverter will be rated 12kW for input (charging) and export.
That's a major change of design.
Until now, GivEnergy's inverters have only delivered half-power for export/discharge.
There is presently no facility to operate these units in parallel, but that is being worked on.
(12kW offers 50A at mains voltages, which will be sufficient for many houses if you don't have an electric shower).
However, there will be a facility to increase the storage capacity by adding up to four DC-modules.
But note that GivEnergy have adopted a 'high-voltage' architecture. The more storage modules you have, the higher the voltage they present to the integral inverter.
The new All-in-One will have six MPPT inputs for solar panels,
each of which will be capable of operating from 90v - 600v, which roughly equates to 3-panels up to 15-panels.
That's a wider range than most other inverters.
For comparison, The Sunsynk ECCO inverters (3.3kW, 5.5kW and 16kW) have MPPT inputs operating between 150v - 425v.
Gateway-2 is a new development from Givenergy which allows in-home appliances to be activated according to If-Then-Else rules which are entered via the App.
It's up to the user to decide what gets connected, which could include:
- an existing (old style) non-Smart EV charger
- an immersion heater to use electricity from solar panels once the battery has reached a certain State of Charge (SoC)
The Gateway-2 also allows the user to define two categories of appliances which will be supplied from the All-in-One storage battery:
- Those essential devices which will supplied from the battery in the event of a power outage (internet, boiler, lights etc)
- Those devices which will be supplied from the battery whilst it still has more than 50% charge available
There will be three new 6kW, 8kW and 10kW 'high voltage' hybrid inverters.
Those three sizes define the maximum input from solar panels.
These are single-phase inverters which can connect to matching Givenergy 'high voltage' battery stacks.
Each battery stack can be 10.4kWh to 20.8kWh capacity...
... and up to four 20.8kWh stacks can be connected to a 'high voltage' hybrid inverter.
The existing 52v storage batteries are not compatible with this HV system.
The power charge/discharge available from the new HV Hybrid Inverters depends on how many battery packs are in the attached stacks.
Typically a 10kWh battery stack will allow the inverter to output around 7.5kW of power.
That's not a great deal.
It could operate a typical ASHP, but isn't sufficient to run the entire house.
Save energy... recycle electrons!
I’ve had no personal performance issues with our 9.5kWh battery at all. It chugs along nicely doing its job.
BUT although GE routinely say their products can be run in parallel the software to make it happen smoothly is often available only a year later. And the new products are not backward compatible. I fancied adding an AIO to our system but unless I programmed it myself on Home assistant it was not viable. Their advice was to sell the 2yr old battery (no resale value since not an open system) and buy one or more AIOs. No thanks.
My next battery hopefully will have 5 wheels when V2H goes operational.

How much research have you done into this?
The large V2G trial undertaken by OVO/Kaluza 5 years ago could only be offered to drivers with a Nissan Leaf.
That's because they use a ChaDEMO connector, which carries the high-current DC wires to/from the vehicle battery.
The great majority of EVs in Europe use a CCS connector.
Home-chargers (7kW) use the top half of the connector to deliver 230v AC to the car.
There are two optional DC pins at the bottom which are used only if you wish to recharge from a commercial charger-unit (typically 50kW)
The present CCS connection system doesn't not facilitate discharging.
Indra Renewable Technologies developed the V2G unit on which the OVO Trial was based.
They were subsequently awarded a grant to create a CCS compatible unit.
How they hoped to achieve that is not publicised, but no public Trial was undertaken and no V2G or V2H units were released.
That need not mean that Indra's approach failed.
It could simply be the result of a decision by the shareholders not to proceed to production units.
Save energy... recycle electrons!
@transparent I got as far as realising that patience would be a necessity! I did know the above at a superficial level but you have spelt it out clearly for anyone reading this thread.

That all sounds very much like the Tesla Powerwall 3, but with slightly higher figures so the GivEnergy always comes out top in a game of Top Trumps (although I note the PW3 MPPT DC voltage range starts a little lower at 60-480V). I'm not complaining, strong competition pushes forward product development and we all benefit.
Samsung 12kW gen6 ASHP with 50L volumiser and all new large radiators. 3.645kWp solar (south facing), Fox ESS inverter.
Solar generation completely offsets ASHP usage annually. We no longer burn ~1600L of kerosene annually.
