GivEnergy serial number check, and which generation you have
A GivEnergy serial number check starts at the rating label, which names the model. The serial number belongs to that one unit, so the label, the firmware family the app shows and the unit's size are what tell you its generation.

Where to find the serial number
Both Gen 3 packs carry the serial number on a label on their right-hand side. That's true of the smaller 5.12 Gen 3 and of the 9.5 Gen 3 alike, as the 5.12 Gen 3's installation manual and the UK edition of the 9.5 Gen 3's manual both show.
On a UK 9.5 kWh battery the serial number reads as two letters, four digits, the letter G and three digits. We checked that on a real label, and we describe it in words rather than print one. We don't know which generation that battery was, so we don't tie the pattern to one.
We don't read those letters and digits as a date, a factory or a model. No GivEnergy document we hold explains them.
A Gen 3 hybrid has a serial number label of its own. It isn't the WiFi serial number or the verification code, which the inverter also carries, so check you've copied the right one.
An All in One 2's serial number is on its product label, and the MPPT box and Gateway 2 carry their own.
No GivEnergy paper we hold shows where the serial number sits on the packs and hybrids from before Gen 3, the AC Coupled, the All in One, the All in One 2 expansion battery and the Giv-Gateway. Photograph the rating label, which names the model either way.

- Giv-Bat 2.6 (Gen 1) The smallest GivEnergy pack, 299 mm tall and 35.5 kg. No breaker on the pack. A separate 100 A DC breaker sits on the wall beside it. Battery firmware in the app starts 30 (for example 3022).
- Giv-Bat 5.2 (Gen 1) 515 mm tall and 63 kg. No breaker on the pack. A separate 100 A DC breaker sits on the wall beside it. One bank of four DIP switches on the pack. Battery firmware in the app starts 30.
- Giv-Bat 8.2 (Gen 1) 669 mm tall and 103 kg. No breaker on the pack. A separate 100 A DC breaker sits on the wall beside it. Battery firmware in the app starts 30.
- Giv-Bat 9.5 (Gen 2) The tallest pack, at 800 mm and 110 kg. A 100 A DC breaker built into the pack. One combined power-and-data plug. Two banks of DIP switches (ID and master/slave). Battery firmware in the app starts 30.
- Giv-Bat 9.5 (Gen 3) 576 mm tall and 85 kg. That's much shorter than a 9.5 Gen 2, and 25 kg lighter. Plug-in sockets marked A and B instead of bolted terminals, a built-in isolator and an on/off button on the right side. Model code GIV-BAT-9.5-G3 on the nameplate (right-hand side). Battery firmware in the app starts 40 (for example 4009). A label on the right-hand side of the pack carries the serial number.
- Giv-Bat 5.12 (Gen 3) 338 mm tall and about 48 kg. Plug-in sockets marked A and B, a pre-installed isolator and a USB port for firmware. Battery firmware in the app starts 40. A label on the right-hand side of the pack carries the serial number.
- Hybrid inverter (Gen 1) An LED display, and a WiFi or 4G dongle in the USB port. No network socket. 440 mm tall and 24 kg. Inverter firmware in the app reads D4xx-A4xx.
- Hybrid inverter (Gen 2) An LCD screen, WiFi built in and a network socket. 410 mm tall and 27.5 kg. Inverter firmware in the app reads D9xx-A9xx.
- Hybrid inverter (Gen 3) The tallest hybrid, at 588 mm and 32 kg. An external WiFi aerial, a network socket and one combined battery plug. Inverter firmware in the app reads D3xx-A3xx. It has its own serial number label, apart from the WiFi serial number and its verification code.
- All in One A tall cabinet, 1,100 mm high and 600 mm wide. It weighs about 174 kg. No solar input. It's AC-coupled and sits beside a solar inverter. It pairs with the Giv-Gateway (up to three 6 kW All in Ones on one Gateway). Inverter firmware in the app reads D6xx-A6xx.
- All in One 2 950 mm tall, so shorter than the original All in One. Can have a separate MPPT box (six solar inputs) beside it. It works with a Gateway 2. GivEnergy says it can't currently run in parallel with the original All in One or a Giv-Gateway. Its serial number is on its product label, and the MPPT box and Gateway 2 carry their own.
- All in One 2 MPPT unit A flat box the width of the All in One 2, with six solar inputs.
- All in One 2 expansion battery Works with the All in One 2 only, up to two per unit.
- Giv-Gateway 410 mm tall with an LED display. Model code GIV-AIO-GW1. Works with the All in One and All in One 3.6. With an All in One it gives the whole house backup in a power cut, and it has an energy meter and a connection point for solar PV.
- Gateway 2 460 mm tall with an LCD screen. Model code GIV-AIO-GW1-2. Works with the All in One 2 only. With an All in One 2 it gives the whole home backup in a power cut, with an energy meter and solar PV connectivity built in.

Reading the code on a rating label
A pack code marks Gen 3 with -G3 at the end, as in GIV-BAT-9.5-G3 and GIV-BAT-5.12-G3. Without that ending, a GivEnergy battery belongs to one of the two older generations, and the size settles which, because the only size made as a Gen 2 is the 9.5 kWh.
A Gateway 2 reads GIV-AIO-GW1-2, where the original Giv-Gateway reads GIV-AIO-GW1.
None of the GivEnergy documents we hold prints a model code for a GivEnergy hybrid or the AC Coupled, so we don't give one. The case itself tells them apart, with an LED display on a Gen 1, an LCD screen on a Gen 2 and an external WiFi aerial on a Gen 3, and so does the firmware number below.
The two All in Ones are easier to tell apart by height than by code, because GivEnergy prints the All in One 2's code in more than one form. The All in One is 1,100 mm tall, against the All in One 2's 950 mm.
Firmware numbers that point to a generation
When you can't get to the label, the inverter's firmware number in the app narrows it down. A Gen 1 hybrid's firmware reads D4xx-A4xx, a Gen 2's reads D9xx-A9xx and a Gen 3's D3xx-A3xx.
An All in One shows D6xx-A6xx, and the AC Coupled D5xx or D2xx.
The families don't run in order of age, so match the letter and the first digit rather than going by how high the number is.
A battery has a firmware number of its own as well, and it splits the Gen 3 packs from the older two generations.

The GivEnergy datasheets we work from
GivEnergy's own copies are linked here, for the 9.5 Gen 2, 8.2, 9.5 Gen 3, 5.2, 5.12 Gen 3 and 2.6 packs, tallest first.
The inverter datasheets cover the Gen 1 hybrid, Gen 2 hybrid, Gen 3 hybrid and AC Coupled.
The datasheets for the Gateway 2 and the Giv-Gateway are pages on GivEnergy's site rather than files.
For the two All in Ones we use the All in One datasheet (June 2023), plus the All in One 2 manual V1 (Oct 2025). Both are distributors' copies, so we name them here without a link.
Where an older GivEnergy document gives a different figure, we still print the current datasheet's, and the table's notes say what the older one gave.
Photograph the rating label
If you're still unsure, go with "Other or not sure" for an inverter or "Not sure" for a pack, and send the photo with the form.
Please don't take it off the wall yourself
A low-voltage GivEnergy pack runs at 51.2 V DC with real fault current behind it. A high-voltage stack runs well above that, and an All in One at around 307 V. Our engineer isolates the system before anything is moved. If your installer has already disconnected it, say so on the form.

Telling GivEnergy units apart
How can I check which GivEnergy model I have?
Read the rating label first, because it names the model. Where it's out of reach, the unit's height and the firmware family in the app usually narrow it down, and a label photo sent with the form lets us confirm it.
Can you check my GivEnergy serial number for me?
We don't read anything into a serial number. The rating label tells us the model, so a clear picture of that label is what helps, sent with the form.
Which GivEnergy battery generation do I have?
Check the battery firmware in the app first. A version beginning 30 means one of the two older generations, and one beginning 40 means Gen 3. Gen 3 packs also carry two plug-in sockets, A and B. The older ones need a separate DC breaker, apart from the 9.5 Gen 2, whose breaker is part of the pack.
How heavy are GivEnergy batteries?
The low-voltage packs run from 35.5 kg for the 2.6 to 110 kg for the 9.5 Gen 2, by GivEnergy's current datasheets. An All in One weighs 173.7 kg with its battery inside. The All in One 2 comes to 181.3 kg.
What are the dimensions of a GivEnergy battery?
Every low-voltage pack is 480 mm wide. Heights run from 299 mm to 800 mm, and depths from 205 mm to 242 mm, by the current datasheets.
When did the GivEnergy All in One come out?
We don't have a launch date from GivEnergy. Its earliest firmware note for the All in One is dated 17 April 2023, and the datasheet we work from is dated June 2023.
