What is the GivEnergy All-in-One 2? A Next-Gen Solution for UK Homes

At its core, the GivEnergy All-in-One 2 is a modular home battery storage system that integrates a high-capacity lithium-iron-phosphate (LiFePO4) battery with a powerful hybrid inverter. Launched in late 2025, this system builds on the success of its predecessor – the original All-in-One – by delivering more power, greater flexibility, and enhanced resilience. It's designed specifically for the UK's variable weather and grid challenges, making it an ideal match for solar battery storage UK setups.

Key Specifications at a Glance

To give you a quick overview, here's a breakdown of the core specs that make the All-in-One 2 a standout in home battery storage systems UK:

These specs aren't just numbers – they're tailored to address common pain points in UK solar battery storage. For instance, the modular design allows you to start small (13.5 kWh for a typical three-bedroom home) and scale up as your needs grow, such as adding an electric vehicle or expanding your family. Priced competitively at around £5,000-£7,000 for the base unit (installation extra), it undercuts rivals like the Tesla Powerwall 3 while offering superior scalability.

As Simon Taylor, Managing Director at GivEnergy, notes in recent announcements: "The All-in-One 2 builds on the success of the original system to deliver more power, more flexibility, and greater resilience than ever before." This isn't hype – early reviews from installers like Spirit Energy highlight its streamlined commissioning via Bluetooth, reducing setup time by up to 50% compared to separate inverter-battery combos.

The Power of Solar Battery Storage: Why UK Homes Need It in 2026

Before we zoom in on the All-in-One 2, let's step back and explain solar battery storage in simple terms. Imagine your rooftop solar panels as a personal power plant, churning out free electricity on sunny days. But here's the catch: most UK households use 70-80% of their energy in the evenings, when the sun's long gone. Without storage, that excess daytime solar goes straight back to the grid – often at a measly 15p/kWh via the Smart Export Guarantee (SEG), while you're paying 25-30p/kWh to import at night.

Enter solar panel battery storage: a rechargeable powerhouse that captures surplus solar (or cheap off-peak grid power) and dispenses it on demand. In 2025, with the UK's push towards net zero by 2050, these systems are more relevant than ever. According to the Energy Saving Trust, pairing solar PV with battery storage can cut bills by £400-£600 annually for an average home, while reducing carbon emissions by up to 1.5 tonnes per year.

Unpacking the Core Benefits

1. Bill Savings and Energy Arbitrage: Charge your battery during off-peak hours (e.g., 7-10p/kWh on Octopus Agile tariffs) or with free solar, then use it during peak times. The All-in-One 2's AI-driven management automates this, potentially saving 85% on bills. For EV owners, it optimises charging for minimal cost.
2. Energy Independence and Backup Power: UK blackouts rose 20% in 2024 due to storms. With the All-in-One 2, you get instant failover – no more fumbling for candles. It prioritises essentials like fridges and lights, keeping your home running for hours or days.
3. Environmental Impact: By maximising self-consumption, you're displacing fossil fuels. LiFePO4 batteries like those in the All-in-One 2 are safer, longer-lasting (6,000+ cycles), and more ethical than cobalt-based alternatives, aligning with UK sustainability goals.
4. Home Value Boost: Properties with solar battery storage systems sell 5-10% faster and for £10,000+ more, per recent Zoopla data. It's a smart investment in a market where green homes command premiums.
5. Grid Support and Incentives: Join virtual power plants (VPPs) via apps like Octopus Flux to earn extra by exporting at peak grid demand. Plus, 0% VAT on installations until 2027 shaves £500-£1,000 off costs.

But not all batteries are equal. Lead-acid options degrade quickly in the UK's damp climate, while some lithium-ion systems lack hybrid capabilities. The All-in-One 2 shines here with its AC/DC flexibility – it works with existing solar inverters or new setups, future-proofing your investment.

Deep Dive: Features That Set the GivEnergy All-in-One 2 Apart

What elevates the All-in-One 2 from a standard home energy storage battery to a must-have? It's the thoughtful engineering for real UK living.

AI-Powered Smart Management

Forget manual tweaks – the system's AI learns your habits, weather patterns, and tariff rates to optimise charging/discharging. Modes include:

• Self-Use: Prioritise solar for home loads.
• Time-of-Use: Charge off-peak, discharge peak.
• EV Optimisation: Sync with chargers for green motoring.

Via the GivEnergy app, you get real-time dashboards, historical analytics, and voice control integration (Alexa/Google). Noise? Under 50dB – quieter than a fridge.

Scalability for Growing Needs

Start with 13.5 kWh (enough for 30-40 kWh daily use) and parallel up to three units for 40.5 kWh total. Add expansion batteries for £2,500 each, handling everything from a cosy flat to a sprawling family home. It's G99-compliant for larger exports, easing DNO approvals.

Robust Build for British Weather

IP65 rating means no rust worries – install in a garage, shed, or even outdoors. The smart fan cooling handles humidity up to 100%, and fire-resistant LiFePO4 cells pass stringent safety tests.

Early adopters rave: A Cambridge Renewables review calls it "unrivalled for power and price," with payback under 5 years when paired with solar. Compared to the Powerwall, it's 20% cheaper with better warranty.

Breaking Down the Two Extra Products: Unlock Full Potential

The All-in-One 2 is brilliant standalone, but these add-ons transform it into a complete solar battery storage UK ecosystem. Let's dissect them.

1. GivEnergy All-in-One 2 Gateway 2: Whole-Home Backup, G98 Compliant

Priced at around £800-£1,000, the Gateway 2 is your system's 'smart switchboard' – a compact device ensuring zero-downtime power during outages. G98-compliant (no DNO notification needed for most homes), it enables 0ms switchover, faster than a blink.

Key Features:

• Seamless Integration: Connects via RS485 to the All-in-One 2, prioritising critical circuits (e.g., lights, heating).
• Load Management: Advanced algorithms shed non-essentials to extend runtime – up to 24 hours on a full charge.
• Grid Services Ready: Export flexibility for SEG earnings, plus VPP compatibility.

Benefits in Action: In a 2024 storm trial, it kept essentials running for 12 hours on 13.5 kWh. For EV owners, it prevents discharge during charging. Installation is plug-and-play, adding just 30 minutes to setup.

Without it, you're limited to partial backup; with it, your home becomes outage-proof. Reviews from Deegesolar.co.uk praise its "dream-like simplicity" for installers.

2. GivEnergy All-in-One 2 MPPT Box: 6-String Solar Optimiser

At £500-£700, this add-on is a solar whisperer – a 6-string Maximum Power Point Tracker (MPPT) that squeezes every watt from your panels, even on tricky roofs.

Key Features:

• Multi-Array Support: Six independent trackers handle up to 20 kW DC input, ideal for north-facing or shaded setups.
• Optimisation Tech: Per-string voltage sensing boosts yield by 10-25% over basic inverters.
• Hybrid Ready: Slots directly into the All-in-One 2 for DC-coupled efficiency (95%+ conversion).

Benefits in Action: On a south-east/west split roof, it could add 5-10 kWh daily harvest – translating to £100+ annual savings. It's lightweight (17.8 kg) and IP65-rated, with easy wiring.

For uneven panels or expansions, it's indispensable. Segen UK calls it "true flexibility," enabling advanced control without complexity.

Real-World ROI: Is Solar Battery Storage Worth It in the UK?

Let's crunch the numbers for a typical UK semi-detached home (3,400 kWh/year use, 4 kWp solar). Base All-in-One 2 install: £8,000 (inc. VAT at 0%). Annual savings: £500 (self-consumption) + £300 (arbitrage/SEG) = £800. Payback: 10 years, but drops to 7 with grants.

Add Gateway 2 (£900): +£100/year in resilience value. MPPT Box (£600): +£150/year yield boost. Total system: £9,500; savings £1,050/year; payback 9 years.

With rising prices (projected 5-10% hike in 2025), ROI improves. Plus, intangible wins: lower stress, greener footprint.

Installation, Maintenance, and Next Steps

Professional MCS-certified installers handle everything in 1-2 days. Expect a site survey, DNO nod (if >3.68 kW export), and app setup. Maintenance? Minimal – annual checks, app alerts for issues.
