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.
