STS installed/commissioned an extra Givenergy battery for me. Communication was great and the engineer did a great job and even tidied up the existing wiring which made it look a great deal nicer than it did. Very happy so far and grateful to the team for their professionalism.

We reached out to Solar Technical Support after our solar energy system stopped working. As GivEnergy 'solar orphans,' we have been extremely pleased with the service from STS - our system was back up and working within a day of us contacting them. We found other solar engineers reluctant or unable to help us, so it has been great to find this organisation. We would definitely use them again and would recommend them to anyone, especially GivEnergy orphans!

We decided to treat ourselves to an upgrade to our existing solar system, and after a little searching, it became evident that Ron and his team provide the service and support we required. Decommissioning and recommissioning our new SunSynk Acure inverter and a wall-mounted Fogstar battery (which is of substantial size and weight compared to the original) was completed swiftly and competently. The installation was perfectly executed, and all upgraded paperwork for the increased battery export capacity was handled by Ron. I have no hesitation in recommending this team of support technicians to you.

Product lineup
Architecture overview
Four product lines, three architectures
GivEnergy's residential range splits cleanly into DC-coupled hybrid inverters (paired with separate GivBat modules), the integrated All-in-One range (battery + inverter in one box), and the standalone EV charger. On the hybrid side, the 3.6 and 5.0kW models (Gen 1, Gen 2 and Gen 3) are LV. The single-phase Gen 3 8.0 and 10.0kW and the three-phase hybrids (6 to 20kW) are HV and use the stackable battery kits.
Product 1 — Hybrid inverters
LV and HV hybrids
GivEnergy hybrid inverters
GivEnergy's hybrid inverters are DC-coupled: solar panels and a battery connect to one unit. Older systems use the Gen 1 or Gen 2 hybrid (3.6 or 5.0kW, LV). The single-phase Gen 3 comes in four ratings: the 3.6 and 5.0kW take LV GivBats, and the 8.0 and 10.0kW (UK launch February 2025) are HV and take the stackable kits. All four single-phase Gen 3 models have in-built WiFi and LAN — no external dongle, no "GivHub".

Battery pairing
→3.6kW + 5.0kW Gen 3: LV GivBats (51.2V) — GivBat 5.12 Gen 3 or GivBat 9.5 Gen 3. Up to 5 in parallel = 47.5kWh max.
→8.0kW + 10.0kW Gen 3: HV stackable kits only, from GIV-BAT-10.2-HV (3 packs, 230VDC) to GIV-BAT-20.4-HV (6 packs, 460VDC). They do not accept 51.2V LV GivBats.
→LV battery systems top out at about 3.6kW, whichever inverter they are on. The Gen 2 and Gen 3 3.6 and 5.0 charge at up to 3.3kW and discharge at up to 3.6kW; a Gen 1 gives up to 2.6kW from the battery. More LV batteries hold more energy but do not charge or discharge faster. HV stacks can do more: about 2.2kW per pack, per GivEnergy's HV inverter manual.
Three-phase HV hybrids
GivEnergy's three-phase hybrids are HV and use the stackable battery kits. 6, 8, 10 and 11kW models were announced for the UK in January 2024, and 12, 15 and 20kW models followed. The specs above cover the single-phase range only.

Product 2 — All-in-One range
Integrated
GivEnergy All-in-One
Battery + inverter in a single 173.7kg floor-standing enclosure (181.3kg on the AIO 2 + MPPT). Three models in the residential range — the original AC-coupled 6kW AIO, the AC-coupled 3.6kW AIO, and the hybrid AIO 2 + MPPT with six independent PV trackers.
| Model | SKU | Output | Capacity | Warranty |
|---|---|---|---|---|
| AIO (original, AC-coupled) | GIV-AIO-AC-13.5 | 6kW continuous / 7.2kW peak | 13.5kWh LiFePO₄ | 12 yrs* |
| AIO 3.6 (AC-coupled) | GIV-AIO-AC-13.5-3.6 | 3.6kW on-grid · 6kW continuous off-grid | 13.5kWh LiFePO₄ | 12 yrs* |
| AIO 2 + MPPT (hybrid) | GIV-BAT-13.5-AIO2 (+ GIV-MPP-20.0-G1) | 6/8/10/11/12kW configurable · 12kVA off-grid | 13.5kWh LiFePO₄ + up to 2 expansion | 15 yrs (manual) |
| AIO 2 expansion battery | GIV-BAT-13.5-AIO2-E | — | 13.5kWh · 307.2V | 15 yrs |
* 12 years on systems installed from 11 September 2023. The original AIO launched in June 2023; the few installed before 11 September 2023 carried 10 years.
Product 3 — GivBat batteries
Storage modules
GivBat LV battery modules + HV stackable kits
LV GivBats (51.2V) talk to LV hybrids over RS485 with dip-switch master/slave addressing, not CAN, and need no terminator. Batteries with a plug connector (Gen 2 and Gen 3) carry comms and power in one plug-in cable; Gen 1 batteries have power cables on lugs and a separate data cable on a green pin connector. At the inverter end the data link uses a green pin connector on Gen 1, an RJ45 BMS port on Gen 2 and a plug on Gen 3. HV stackable kits are a separate architecture for the HV hybrids: the Gen 3 8.0 and 10.0kW and the three-phase models (CAN, 230–460VDC depending on kit size).
LV GivBat range — datasheet specs
| Model | SKU | Capacity | DoD |
|---|---|---|---|
| GivBat 2.6 Gen 1 | GIV-BAT-2.6 | 2.6 kWh | 80% |
| GivBat 5.2 Gen 1 | GIV-BAT-5.2 | 5.2 kWh | 80% |
| GivBat 8.2 Gen 1 | GIV-BAT-8.2 | 8.2 kWh | 80% (about 2019–21) · 100% (from 2021) |
| GivBat 9.5 Gen 2 | GIV-BAT-9.5 | 9.5 kWh | 100% |
| GivBat 5.12 Gen 3 | GIV-BAT-5.12-G3 | 5.12 kWh | 100% |
| GivBat 9.5 Gen 3 | GIV-BAT-9.5-G3 | 9.5 kWh | 100% |
All LV GivBats: 51.2V nominal · LiFePO₄ · IP65. Gen 1 2.6 and 5.2 are 80% DoD per datasheet. The 8.2 came in two versions under one name: 80% DoD (sold about 2019 to 2021, about 6.6 kWh usable), then 100% DoD from 2021. Everything else is 100% DoD.
Warranty: 12 years (to 70% capacity) on systems installed from 11 September 2023. Batteries installed before that carried 10 years at 70% capacity. The current datasheets print 12 years on every model, including discontinued Gen 1 packs, so they do not show what an older install carries.
HV stackable kits (for the HV hybrids)
| Kit | SKU | Capacity | Voltage | Weight |
|---|---|---|---|---|
| 3-pack HV stack | GIV-BAT-10.2-HV | 10.2 kWh | 230VDC | 119.8 kg |
| 4-pack HV stack | GIV-BAT-13.6-HV | 13.6 kWh | 307VDC | 155.3 kg |
| 5-pack HV stack | GIV-BAT-17.0-HV | 17.0 kWh | 384VDC | 190.8 kg |
| 6-pack HV stack | GIV-BAT-20.4-HV | 20.4 kWh | 460VDC | 226.3 kg |
HV stack uses CAN over RJ45 — the architecture where a 120-ohm terminator does exist (unlike LV). Comms uses the orange HV-kit connector. A stack holds 3 to 6 packs. GivEnergy's HV inverter manual allows up to 4 stacks in parallel, using the newer kits with In and Out connections.

The All-in-One (AIO) is an AC-coupled or DC-coupled wall unit with the inverter and a 13.5kWh LiFePO₄ battery integrated into one enclosure. The Gen 3 hybrid is a DC-coupled inverter on its own — it pairs with external batteries: LV GivBat modules on the 3.6 and 5.0, HV stackable kits on the 8.0 and 10.0. The AIO is common on retrofit jobs where one unit was wanted; a Gen 3 + GivBat system can grow by adding batteries later. None of the Gen 3 hybrids are an AIO and vice versa — they are different product lines.
AIO 2 + MPPT supports up to two GIV-BAT-13.5-AIO2-E expansion batteries (HV, 307VDC, 15-year warranty per datasheet) — so total capacity grows in 13.5kWh blocks. The original AC-coupled AIO and the AIO 3.6 are 13.5kWh integrated units; additional storage there is normally added by a separate Giv-Bat-on-hybrid system rather than expanding the AIO itself.
Yes. The inverter runs timed charge windows itself, and you can set them free in the GivEnergy app when your phone is on your home network (local control since app version 4.0.5, May 2026). Several smart tariffs (Octopus Intelligent Go, Agile, Flux) integrate via the GivEnergy cloud API. GivEnergy Software Ltd, which runs the app and portal and is still trading, lists third-party API access under its paid GivEnergy Premium plan (£4.99 a month), along with remote access, the web portal and history graphs. For owners who would rather not depend on the cloud, third-party tools such as Home Assistant integrations and Predbat cover monitoring and tariff optimisation locally.
It depends on when the system was installed. GivEnergy's 12-year warranty covers residential batteries, inverters, the All-in-One and the Gateway on systems installed from 11 September 2023, with batteries covered to 70% of their capacity. The clock runs from installation or commissioning, whichever came first. Systems installed before that keep the terms on their own paperwork: batteries then carried 10 years at 70% capacity, and inverters 5 years, or 10 years if an extended warranty was paid for (the paperwork shows which). Current datasheets print "12 years" even on discontinued models, so a datasheet does not show what an older install carries. The AIO 2 + MPPT and its expansion battery are 15 years, and the EV charger is 3 years. However: GivEnergy Ltd entered administration on 9 April 2026 and the administrator has confirmed no further hardware warranties will be honoured by GivEnergy Ltd. Alternative recovery routes are installer cover, IBG, Section 75, MCS Consumer Code, and Consumer Rights Act 2015. See our warranty page.
No. The GIV-EV-7.2 (7kW at 32A, Type 2 tethered, IEC 62196-2) can run as a standalone grid charger, alongside a third-party solar system in CT-Meter mode, or fully integrated with a GivEnergy inverter via Inverter Control Cloud or Local. The configuration mode is set at commissioning. See the dedicated EV charger page for the four modes in detail.
Older installs are usually a Gen 1 or Gen 2 hybrid inverter plus a Gen 1 GivBat (2.6, 5.2 or 8.2). The 8.2 came in two versions under one name: 80% DoD (sold about 2019 to 2021, about 6.6 kWh usable), then 100% DoD from 2021. The 9.5 Gen 2 (100% DoD) followed. The Gen 3 hybrid and GivBat 9.5/5.12 Gen 3 came later. Look at the label for the SKU prefix — hybrids are GIV-HY-* and batteries are GIV-BAT-*. STS can identify any GivEnergy install from a clear photo of the inverter label.
