Givenergy All in One & Fogstar compared in here.
Givenergy:
The All in One, contains 4 modular battery packs totalling 13.5kWhGateway if one is needed (+£560). 6 units can be connected in parallel totalling 80kWh.
The All in One is supplied as a complete system, including an Inverter and a Modbus energy meter, repkacing the need for the EM115 meter.
The unit is IP65 rated so suited for external installation.
The main Tech spec’s are:
6000W nominal AC output power
Peak Power 7.2kW peak/6.0kW continuous (7.2kW @ 10s, 6.5kW @ 30s)
IP65 rating
Dimensions 1100H x 280D x 600W (mm)
12 year warranty
Battery Capacity 13.5kWh
Communication Interfaces CAN
Nominal Voltage 307V
Maximum Charge/Discharge Current 25A
Battery Voltage Range 260-346V
Depth of Discharge 100%
Life Cycle 15-20 years.
Other than knowing GivEnergy use LFP/LiFePO4 batteries there is no information on Grade of battery, Cell model or Cell Pack arrangement used however, it can be assumed to have and energy density of around 160 -180 kW/Kg. There is also no information
Price circa £6,000 with delivery (TRADESPARKY.COM)
Fogstar rack battery:
Fogstar battery is available a single unit 5.12kWh (£1,050) and as a 15kWh (£3,000) or 30kWh (£6,000) in a rack bundle. A 15kWh rack contains 3 batteries and 30kWh rack 6 batteries c/w cabinet) The ability to connect up to 15 rack batteries in parallel.
This battery differs to Givenerg’s AIO and therefore is part of a wider solution, containing only the battery and BMS and Inverter protocols for most majour brands, with the ability to change them. It is also not suitable for external installation, unless installed in a out building – shed garage etc.
Standout features:
Each 5.12kWh battery contains 16 premium Grade A EVE cells
UK designed internal heater – automatically activates internal heating system when temperatures dip below 5°C, enabling charging even in conditions as low as -20°C.

What I like with the Fogstar units, is their openess providing you with the Cell model along with the Cell pack configeration and of course who the manufacturer is, from which you can find valuable information. See Link

I’ll make seperate post comparing a Fogstar 5.12kWh with a Givenergy 5.12kWh (both same price) which is part of a range that also includes a 2.6kWh unit. My guess as we stand now, is your paying for the privelidge for the All in One.
