Ron made more sense in 20 mins than our installer has done over the last 12 months There is a jungle out there and you need someone like Ron to give a comprehensive overview and solution

Excellent service from Solar Tech Support. Extremely quick to respond, easy to deal with and clearly very talented engineers. They were persistent throughout a complex GivEnergy battery issue and resolved everything completely. Highly knowledgeable, professional and reassuring support from start to finish. Highly recommended.
David Harris · May 2026
My 90-year-old father-in-law had a solar system installed nearly three years ago that never worked properly and kept tripping out. Neither the original installer nor GivEnergy could resolve the issues, and we were even pushed towards replacing the system entirely when GivEnergy went bust. I contacted Ron at Solar Tech Support via WhatsApp, and within a few hours he had diagnosed multiple faults — including incorrect wiring that posed a potential fire risk. He carried out a home visit in Nottingham for £295 (including parts), fixed everything, completed firmware updates, and ensured the system was fully operational. Since then, it has worked perfectly. Ron was knowledgeable, responsive, and took the time to explain everything clearly. Highly recommended — excellent value and complete peace of mind.

I can’t praise this firm enough. After hearing my solar panels rattling in very windy conditions, I contacted Solar Tech (as my installers no longer trade). Ronald was fantastic at explaining what he thought the issue was likely to be. Communication was great throughout keeping me fully updated. The team worked really hard on the day to carry out the necessary work. I can now sleep soundly at night without worrying about the solar panels on my roof. I would thoroughly recommend this firm. Thank you for sorting the problem out.

Overview
Battery + inverter + smart energy management in one floor-standing unit
The GivEnergy All-in-One integrates 13.5kWh of LiFePO₄ storage and the inverter in a single 173.7kg floor unit (181.3kg on AIO 2 + MPPT). The architecture differs by model: original AIO and AIO 3.6 are AC-coupled (cable in from an existing PV inverter); AIO 2 + MPPT is hybrid — solar panels connect directly to a dedicated MPPT module with six independent trackers.
All AIOs carry full EPS backup. Per datasheets: original AIO = 6kW continuous / 7.2kW peak; AIO 3.6 = 3.6kW on-grid / 6kW continuous / 7.2kW peak off-grid; AIO 2 + MPPT = 12kVA continuous / 14.4kVA peak off-grid. Backup only powers the designated essential-load circuit, wired at install. Grid compliance (G98 vs G99) is set by the inverter output per phase, not battery capacity.
AC-coupled (AIO + AIO 3.6) advantage
· Retrofit-friendly: existing PV inverter stays
· Original AIO: 6 in parallel max (per datasheet)
· AIO 3.6: 3 in parallel max
Hybrid (AIO 2 + MPPT) advantage
· Six independent PV trackers via the GIV-MPP-20.0-G1
· Up to 20kW of PV directly into the AIO
· 15-year warranty per datasheet (pre-administration)
Original AIO — AC-coupled
GIV-AIO-AC-13.5 — original All-in-One
The original AC-coupled AIO — 13.5kWh of integrated LiFePO₄ storage and a 6kW continuous inverter (7.2kW peak). Connects via AC cable to an existing PV inverter's AC output.
Key specifications
SKUGIV-AIO-AC-13.5
Output6kW continuous · 7.2kW peak
Battery13.5kWh LiFePO₄ · 307V nominal
Dimensions / weight1100H × 600W × 280D mm · 173.7kg
Warranty (datasheet)12 years
ParallelUp to 6 units (per datasheet)
Features & capabilities
· Grid Services Ready
· EPS backup at 6kW continuous
· AC-coupled — connects to existing PV inverter
· Floor-standing, IP65
· Comms with portal via in-built connectivity
Use case: retrofit onto an existing solar PV install. The 6kW continuous output suits homes that export at meaningful rates during sunny periods. Up to 6 in parallel for higher-capacity sites.
AIO 3.6 — AC-coupled lower-output
GIV-AIO-AC-13.5-3.6 — All-in-One 3.6
Same 13.5kWh storage, same chassis (173.7kg), but rated at 3.6kW on-grid output — fits within the G98 single-notification limit per phase. Off-grid the AIO 3.6 can deliver 6kW continuous and 7.2kW peak per datasheet.
Key specifications
SKUGIV-AIO-AC-13.5-3.6
Output (on-grid)3.6kW continuous / 3.6kW peak
Output (off-grid)6kW continuous / 7.2kW peak
Battery13.5kWh LiFePO₄ · 307V nominal
Warranty (datasheet)12 years
ParallelUp to 3 units
Features & capabilities
· G98 single-notification fit (3.6kW per phase on-grid)
· 6kW off-grid continuous — better backup than the on-grid figure suggests
· Same chassis as the original AIO
· EPS backup mode
Use case: properties where the DNO restricts on-grid output to G98 (≤ 3.68kW per phase), or where the customer prefers a 3.6kW export setting. Off-grid capability is unchanged.
AIO 2 + MPPT — flagship hybrid
GIV-BAT-13.5-AIO2 — All-in-One 2 + MPPT
The flagship of the AIO range. The AIO 2 inverter on its own is a 6/8/10/11/12kW configurable hybrid with 13.5kWh integrated storage; pair it with the GIV-MPP-20.0-G1 MPPT module for a hybrid system with six independent PV trackers and up to 20kW of PV input. The expansion battery (GIV-BAT-13.5-AIO2-E) adds another 13.5kWh in a 307V package — up to two of those, for a maxed-out 40.5kWh AIO 2 + MPPT system.

Battery (internal)13.5kWh · 307V · 52Ah · CAN comms
Warranty (datasheet)15 years
Weight181.3 kg
Features & capabilities (datasheet)
· Six independent MPPT trackers — complex roofs and shading tolerance
· Up to 20kW PV via the dedicated MPPT module
· Configurable 6–12kW output to match DNO ceiling
· 12kVA off-grid for serious backup loads
· Two GIV-BAT-13.5-AIO2-E expansion batteries supported
· Grid Services Ready
Six independent MPPT trackers — why it matters:
1. Shading tolerance. One shaded string does not drag down the others — each tracker optimises its own string.
2. Multi-direction arrays. East / south / west splits get optimal tracking across the day.
3. Larger arrays. Six trackers + 20kW PV input handles roof setups that single-MPPT inverters cannot.
Which AIO
Choosing between the three AIO models
Three different jobs:
✓ Original AIO (GIV-AIO-AC-13.5)
· You already have a PV inverter
· Want 6kW on-grid continuous
· May parallel 2–6 units for capacity
· 12-year warranty (post-admin caveat)
✓ AIO 3.6 (GIV-AIO-AC-13.5-3.6)
· DNO restricted to G98 per phase
· You prefer the simpler notification path
· Still want 6kW off-grid for backup
· 12-year warranty (post-admin caveat)
✓ AIO 2 + MPPT (GIV-BAT-13.5-AIO2)
· New build with fresh PV
· Complex roof — need six trackers
· Want up to 20kW PV input
· 15-year datasheet warranty
When to choose a Gen 3 hybrid + GivBat instead
· You want the inverter on the wall + battery separate
· You want to start small and add batteries piecewise
· You want mix-and-match battery sizes
· 12-year hybrid warranty (datasheet)
Post-administration note: the GivEnergy hardware works regardless of GivEnergy Ltd's administration. What has changed is the warranty enforcement route — claims direct against GivEnergy Ltd no longer succeed. See the warranty page for the alternative routes (installer cover, IBG, Section 75, MCS Consumer Code, Consumer Rights Act 2015).
GivEnergy All-in-One questions
AIO is a single floor-standing unit containing both the inverter and the battery. Original AIO (GIV-AIO-AC-13.5) and AIO 3.6 (GIV-AIO-AC-13.5-3.6) are AC-coupled — they connect to the AC output of an existing PV inverter. AIO 2 + MPPT is hybrid — solar panels connect directly to the AIO's built-in MPPT module (six independent trackers per datasheet). A standalone Gen 3 hybrid + GivBat is the modular alternative — separate boxes, more flexible for capacity changes.
AC-coupled AIO (original + AIO 3.6) needs an existing PV inverter to charge from solar — without one it can only grid-charge using timed-charge windows. AIO 2 + MPPT is the right choice for a new install with fresh panels because its built-in MPPT module accepts up to 20kW of PV directly across six trackers.
Original AIO datasheet notes "Number of Parallel Operation: 6 (coming soon)" — i.e. up to 6 units in parallel for the original. AIO 3.6 datasheet shows 3 in parallel. AIO 2 + MPPT supports up to two GIV-BAT-13.5-AIO2-E expansion batteries — each adds 13.5kWh, so a maxed-out AIO 2 + MPPT stack is 40.5kWh.
AIO 2 + MPPT pairs the AIO 2 inverter (6/8/10/11/12kW configurable on-grid; 12kVA continuous and 14.4kVA peak off-grid per datasheet) with an optional MPPT module (SKU GIV-MPP-20.0-G1, 20kW max PV input, six independent trackers). The datasheet states a 15-year warranty — both for the inverter and the GIV-BAT-13.5-AIO2-E expansion battery (which the original AIO and AIO 3.6 do not get — they were 12-year products). However, GivEnergy Ltd entered administration on 9 April 2026 so the manufacturer warranty is no longer being honoured by GivEnergy Ltd — the framing on warranty applies across the range.
Yes. Per datasheets: original AIO backup = 6kW continuous / 7.2kW peak. AIO 3.6 = 6kW continuous / 7.2kW peak off-grid. AIO 2 + MPPT = 12kVA continuous / 14.4kVA peak off-grid. EPS only powers the designated essential-load circuit — needs to be wired correctly at install. G98 / G99 compliance is determined by the inverter's rated on-grid output per phase, not by battery capacity.
A 10% reserve is a sensible default to protect cell health. If you rely on EPS for blackout backup, set higher (20–30%) so there is always reserve available during an outage. Per the GivEnergy cold-weather KB, charging is inhibited below 0°C — so an AIO in an unheated location may sit at low SoC on cold mornings until cells warm; that is expected, not a fault.
