G4 Single Phase ESS Kits

As a trusted UK supplier, Sinoah Energy stocks these complete systems in our UK warehouse for fast, consolidated delivery to installers and trade partners nationwide. Available in configurations from 3.6kW/7kWh to 12kW/56kWh, the Sinoah G4 Single Phase ESS Kits deliver more energy from your roof, faster protection during outages, and greater weather resistance – making them the definitive choice for UK homeowners who want the best.

The UK Roof Problem: Why Two MPPTs Waste Solar Energy

UK homes have complex roofs. Unlike the simple south-facing arrays common in sunnier countries, British roofs often sprawl across multiple orientations – east for morning sun, south for midday peak, west for afternoon generation. A typical detached house might have panels on all three slopes.

This creates a problem for standard inverters with only two MPPT trackers. When multiple roof orientations share a single MPPT, the inverter forces all strings to operate at a compromised voltage. The result? Reduced efficiency, wasted solar generation, and hundreds of pounds of lost savings every year.

The G4 series solves this at the source. The 8kW, 10kW, and 12kW G4 inverters feature four independent MPPT trackers – one for each roof orientation. Each string operates at its individual maximum power point, capturing 5–10% more annual solar energy than a two-tracker inverter. For a typical UK home with panels on three roof faces, this can add 400–800kWh of extra generation per year – equivalent to £100–£200 in additional annual savings.

Real-World Data: Four MPPTs vs Two MPPTs

An installer we work with in the South East fitted two identical 8kWp systems on adjacent homes – both with panels spread across south, east, and west roof slopes. One home received a standard two‑MPPT inverter; the other received the Sinoah G4 8kW inverter with four MPPT trackers.

After 12 months of monitoring, the results were conclusive: the four-MPPT system generated 7.2% more energy than the two-MPPT system – 576kWh extra over the year. At current electricity prices (25p/kWh), that’s an additional £144 in savings. Over the 25-year lifespan of the solar system, that adds up to £3,600 – more than enough to justify the investment.

The reason is straightforward: on a multi-orientation roof, the east-facing panels peak in the morning, south-facing panels peak at midday, and west-facing panels peak in the late afternoon. A two-MPPT system forces multiple strings to operate at a compromise point. With four MPPTs, each orientation operates at its peak independently, capturing more energy across a broader portion of the day.

IP66 Weatherproofing: Install Anywhere, Worry About Nothing

The G4 series carries an IP66 ingress protection rating – a significant upgrade from the IP65 rating on G3 and most competitors. What does this mean in practice?

· External walls – Install directly on the side of the house without concern about driving rain

· Exposed locations – No need for protective enclosures or overhangs

· Coastal areas – Salt spray resistance built in, no corrosion concerns

· Open carports – Fully protected against wind-driven rain and snow

For UK homeowners, this means installation flexibility. No more compromising on internal space. No more concerns about weather damage. The G4 inverter can go wherever it’s most convenient.

Sub-4ms Whole-Home Backup: The Speed That Matters

When the grid fails, every millisecond counts. The G4 series switches to battery power in under 4 milliseconds – less than a quarter of a 50Hz AC cycle. This is fast enough to keep sensitive electronics running without interruption:

· Computers – No rebooting, no lost work

· Routers – Internet stays live during the outage

· Smart home systems – Lighting, heating, and security remain operational

· Medical equipment – Life-critical devices stay powered

With 200% surge capacity and the optional backup box, the G4 system provides true whole-home backup, not just essential circuits. Run your heat pump, charge your EV, cook dinner, and keep the lights on – all during a grid outage.

Real Customer Feedback

“Yup, mine works flawlessly, two batteries attached. No complaints. Have barely touched the grid since 2nd battery was attached.” – Sinoah user, Whirlpool Forums

“AC Coupled 5kW Inverter with 30kW Battery Storage... Working well through the NeoVolt App and using primarily for Personal use, Charge my Mini Cooper EV.” – Sinoah user, Whirlpool Forums

“The battery looks to be well made.” – Luke NSW, SolarChoice review

“One of the more affordable all-in-one battery systems – Fast switchover time in a blackout.” – SolarQuotes review

Why 7kWh Modules? The Granularity Advantage

In addition to using the 14kWh battery modules, the G4 series also offers an option of 7kWh battery modules – half the capacity of the 14kWh modules. This provides two significant advantages:

Precise System Sizing – With 7kWh increments, you can size your system precisely to your needs. Not every home needs 14kWh increments. A small home might want 21kWh (3 modules). This precision means you don‘t overpay for capacity you don’t need.

Lighter Handling – At 78kg per module, the 7kWh units are significantly lighter than the 128kg modules, making installation easier and safer for installers.

From an Installer’s Perspective

We asked a UK MCS-certified installer who has fitted over 40 G4 systems what makes the series stand out:

“The four MPPT trackers are the reason I specify G4 for larger jobs. When you’ve got east, south, and west-facing panels on a single roof, the difference in generation is significant. The IP66 rating means I can install on external walls without worrying about callbacks. And the sub-4ms switching is the fastest I’ve seen – customers actually notice the difference during power cuts.”

Installation flexibility – The IP66 rating and lighter 7kWh modules make G4 suitable for installations that would be difficult or impossible with other systems.

Commissioning – The inverter‘s LCD display and NeoVolt App guide installers through setup in under 30 minutes.

Fewer callbacks – The weatherproof design and pre-matched components mean fewer service issues down the line.

Smart Tariff Optimisation: The British Way to Save

UK homeowners are uniquely positioned to benefit from battery storage through time-of-use tariffs. With Octopus Go and similar tariffs, you can charge your battery overnight at 7–9p/kWh and use it during peak 25–35p/kWh periods. The G4’s integrated EMS automates this process:

· Overnight charging – The system automatically charges the battery during the cheapest off-peak hours

· Peak discharge – The battery powers your home during the most expensive periods

· Solar prioritisation – When the sun is shining, the system uses solar first, stores excess, and minimises grid import

· EV integration – The system can coordinate with EV charging to maximise savings

For a typical 4-bedroom home on Octopus Go with a 56kWh battery, annual tariff arbitrage savings alone can reach £1,200–£1,600.
