GivEnergy Gen 3 Hybrid — 3.6 / 5.0 / 8.0 / 10 kW

The GivEnergy Gen 3 hybrid inverter pairs solar PV with battery storage in a single DC-coupled unit. Four single-phase models: the 3.6 and 5.0kW are LV (RS485 to GivBat 51.2V batteries, 580V max PV), and the 8.0 and 10.0kW are HV (CAN to the HV stackable kits). All four have in-built WiFi and LAN — no external dongle, no "GivHub". There is also a separate three-phase HV range, from 6 to 20kW. Figures on this page come from GivEnergy's own datasheets and manuals.

Great experience with STS great communication from Ron, very helpful and knowledgable. Installed me a second Givenergy battery to help take the strain off my original 9.5 that needs refurb due to a weak cell. They secured me an 8.2 arranged install. Levi arrived the whole install was done within 1.5 hours - great tidy job. Worked with me to alter my setup to allow easy removal of my 9.5 when i can get it away for refurb - very happy with their service and its reassuring to know there is a company out there that can help look after my givenergy system

Cannot say enough how impressed I have been with Ronald at Solar Tech Support. When faced with not sure what to do next, I was recommended his services via a GivEnergy Community Group. Within an hour my system was back up and running again. Phew!!

Emma Fletcher · Oct 2026 Google

Ronald at Solar Tech Support was very quick and knowledgeable in helping me restart my GivEnergy solar electric battery. I would highly recommend his services.

Thomas Croke · Aug 2026 Google

Ron has come to our rescue once again! After sorting out our GivEnergy battery issue, he was on hand to help us find a solution to data logging issues caused during install of an additional inverter. He's helpful, patient and extremely knowledgeable. Utterly brilliant service. Thank you again!

Edward Johnson · Aug 2026 Google

We were having problems with our inverter, couldn’t get an early response from our installer a stressed conversation between our installer and solar tech support led to a text to us to authorise connection to your company . Ron was a very helpful and knowledgeable man who tried with a bit of difficulty as we are pensioners and very knowledgeable. Spent time on phone without making us feel small.we would recommend this company if you have any problems. Thanks Ron 5 star

Me and the boss · Aug 2026 Trustpilot

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.

Overview

DC-coupled hybrid — four single-phase models, two architectures

The Gen 3 hybrid is a DC-coupled inverter that connects solar PV strings directly to its MPPT inputs and integrates a battery interface in the same chassis. Four models in the single-phase range. The 3.6 and 5.0kW are LV machines (battery voltage 45–58V, RS485 comms) — they pair with GivBat 51.2V LV modules. The 8.0 and 10.0kW are fundamentally different machines: HV (340V nominal battery voltage, CAN interface) — they pair with the pre-built HV stackable kits. All four have in-built WiFi and LAN. There is no external dongle and no "GivHub" product on the Gen 3 side. We hold datasheets for the 3.6, 5.0 and 8.0; figures for the 10.0 come from GivEnergy's 8.0 and 10.0 manual.

There is also a separate three-phase HV range, from 6 to 20kW. The 6, 8, 10 and 11kW models were announced for the UK in January 2024, and 12, 15 and 20kW models followed. They use the same HV stackable battery kits. The rest of this page covers the single-phase models.

5.0 at a glance

· 5kW AC output; from the battery, up to 3.3kW charge and 3.6kW discharge
· Up to 5 LV GivBats in parallel (5 × GivBat 9.5 = 47.5kWh)
· G99 certified: needs DNO approval before connection
· Same chassis size as the 3.6 — same wall footprint

Worth knowing: the 5.0 is rated 5kW, but from the battery it gives up to 3.6kW, the same as the 3.6. LV battery systems top out at about 3.6kW whichever inverter they are on, and more GivBats add stored energy, not power.

Gen 3 8.0 and 10.0 kW — HV

GIV-HY-8.0 and 10.0 — Gen 3 HV hybrids

The HV models in the single-phase Gen 3 range, and fundamentally different machines from the 3.6 and 5.0. HV battery only: the 8.0 has a battery voltage range of 120–510V (nominal 340V) and a CAN interface — it does NOT accept LV GivBats. 600V max PV, 12kW total DC across 4 strings (2 trackers × 2 strings each), 8kW EPS backup with 50A pass-through, and battery charge and discharge up to 8kW and 8.5kW. AFCI arc fault detection per the datasheet. The 10.0 (GIV-HY-10.0-G3-HV) shares the 8.0's manual: 10kW rated output, up to 10kW on the EPS circuit and the same HV batteries over CAN. Both came to the UK in February 2025. Both are single-phase: the three-phase hybrids are a separate HV range.

Important — HV battery only. The 8.0 and 10.0 Gen 3 pair with pre-built HV stackable kits per the GivEnergy Stackable Batteries datasheet: GIV-BAT-10.2-HV (3 packs, 230VDC, 10.2kWh), GIV-BAT-13.6-HV (4 packs, 307VDC, 13.6kWh), GIV-BAT-17.0-HV (5 packs, 384VDC, 17kWh) or GIV-BAT-20.4-HV (6 packs, 460VDC, 20.4kWh). They do not accept LV GivBat modules.

Battery pairing — by model

Which battery pairs with which Gen 3

Battery pairing is determined by the inverter's battery interface — RS485 + 45–58V on the 3.6/5.0, CAN + HV on the 8.0 and 10.0. Wires of the right type, dip switches set correctly on LV, and HV-kit configuration handled at install. Maximum LV stack size is 5 per the Gen 3 battery datasheets ("Parallel Capability: Up to 5"). LV battery systems top out at about 3.6kW whichever inverter they are on: a 3.6 or 5.0 with 5 × 9.5kWh batteries still charges at up to 3.3kW and discharges at up to 3.6kW. HV stacks can do more, about 2.2kW per pack per GivEnergy's HV inverter manual.

3.6 and 5.0 (LV) — battery options

· GivBat 5.12 Gen 3 (5.12kWh, 100% DoD)
· GivBat 9.5 Gen 3 (9.5kWh, 100% DoD, unlimited cycles)
· GivBat 9.5 Gen 2 (legacy, RS485)
· GivBat 8.2 / 5.2 / 2.6 Gen 1 (older, with Gen 3 master + DC isolator)
· Max 5 in parallel — 47.5kWh max LV stack

8.0 and 10.0 (HV) — battery options

· GIV-BAT-10.2-HV (3 × 3.4kWh packs, 10.2kWh, 230VDC)
· GIV-BAT-13.6-HV (4 packs, 13.6kWh, 307VDC)
· GIV-BAT-17.0-HV (5 packs, 17.0kWh, 384VDC)
· GIV-BAT-20.4-HV (6 packs, 20.4kWh, 460VDC)
· Up to 4 stacks in parallel with the newer kits (In and Out connections)
· LV GivBats are NOT compatible with the 8.0 or 10.0

FAQ

GivEnergy Gen 3 Hybrid questions

All four are single-phase. The 3.6 and 5.0 are LV inverters (battery voltage range 45–58V, RS485 comms) — they pair with LV GivBats (51.2V nominal). Both have 580V max PV voltage, 7.5kW max DC input per string, and 3.6kW EPS backup output; from the battery they charge at up to 3.3kW and discharge at up to 3.6kW. The 8.0 and 10.0 are HV (340V nominal, CAN interface). The 8.0 datasheet gives a battery voltage range of 120–510V, 600V max PV voltage, 12kW max DC input, and 8kW EPS backup with a 50A pass-through; the 10.0 gives 10kW output and up to 10kW EPS backup per its manual. Neither accepts LV GivBats — they pair only with the HV stackable kits (GIV-BAT-10.2-HV through GIV-BAT-20.4-HV).
No. Per the GivEnergy Hybrid Inverter 8.0 Gen 3 datasheet (V2.0 NOV 25), the AC Connection field reads "Single Phase", and the 3.6, 5.0 and 10.0 are single-phase too. Three-phase GivEnergy hybrids are a separate HV range, from 6 to 20kW: the 6, 8, 10 and 11kW models were announced for the UK in January 2024, and 12, 15 and 20kW models followed. They use the same HV stackable battery kits. We don't recommend GivEnergy for new systems. We still support and supply parts for existing ones.
Yes. All Gen 3 hybrid inverters require external storage — the unit on the wall is the inverter only. For the 3.6 and 5.0 (LV), pair with GivBat 5.12 Gen 3 or GivBat 9.5 Gen 3 (or Gen 1/Gen 2 GivBats with a Gen 3 master); up to 5 modules in parallel per datasheet. For the 8.0 and 10.0 (HV), pair with a pre-built HV stackable kit, from GIV-BAT-10.2-HV (3 packs) to GIV-BAT-20.4-HV (6 packs). Modular design means you can add capacity later without replacing the inverter.
Per the datasheets the 3.6, 5.0 and 8.0 have "In-Built WiFi and LAN", and the 8.0 and 10.0 manual shows the same on the 10.0 — no external dongle needed, no "GivHub" product. Communication interface to the portal is WiFi (USB) or LAN. There is also RS485 for meter and (on the 3.6/5.0) BMS, and CAN on the 8.0 and 10.0 for the HV battery kit.
GivEnergy's 12-year warranty covers Gen 3 hybrids on systems installed from 11 September 2023, with the clock running from installation or commissioning, whichever came first. Before that date, GivEnergy inverters carried 5 years, or 10 years if an extended warranty was paid for; your paperwork shows which. The current datasheets print "12 years", but a datasheet does not show what an older install carries. POST-ADMIN: 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 of the Consumer Credit Act, MCS Consumer Code redress, and Consumer Rights Act 2015 claims. See the warranty page for the full walk-through.
Datasheet PV input ratings: Gen 3 3.6 = 7.5kWp per string, 2 trackers with 1 string each (2 strings total). Gen 3 5.0 = 7.5kWp per string, same configuration. Gen 3 8.0 = 12kW total DC input, 2 trackers with 2 strings each (4 strings total). As a rough guide, 350–400W panels: 3.6 / 5.0 hybrids handle roughly 18–22 panels total across both strings; the 8.0 handles 28–35+ across four strings. Always size to roof, panel spec, and shading — and a qualified MCS installer must complete the actual design.
Yes. All Gen 3 hybrids run on locally-stored firmware. Solar charging, battery discharge, EPS backup on grid outage, and any already-saved charge schedule continue regardless of cloud status. The free GivEnergy app (Standard tier) also works without the cloud when your phone is on your home network: it shows live power flow, state of charge and meter totals, and since app version 4.0.5 (May 2026) it can change the inverter's settings locally, with no login or subscription. What needs the cloud is GivEnergy Premium (£4.99 a month): remote access away from home, the web portal, history graphs, automation and third-party API access. GivEnergy Software Ltd runs the app, the portal and Premium, and is still trading. Third-party tools such as Home Assistant integrations can also read the inverter over your own network.
