G3 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 10kW/56kWh, the NeoVolt G3 Single Phase ESS Kits deliver a ready-to-install solution that eliminates the guesswork of component matching – giving installers faster installations and homeowners reliable, long-lasting energy independence.

The Installer’s Problem: Component Matching Takes Time

Every UK solar installer knows the drill. A customer wants battery storage. You spec an inverter from one brand, batteries from another, then spend hours checking compatibility – will the BMS communicate properly? Is the voltage range matched? Will the warranty hold up if something goes wrong with a mixed-brand system?

One installer we spoke to put it bluntly: “I’ve had jobs where the inverter and battery just wouldn’t talk to each other. Two hours on the phone with tech support, firmware updates, endless troubleshooting – and I’m not getting paid for any of it.”

The Sinoah G3 Single Phase ESS Kits solve this problem at the source. They are pre-matched systems – the hybrid inverter and stackable battery modules are designed, tested, and certified to work together. Communication protocols are pre-configured. Voltage ranges are perfectly aligned. The installer doesn’t need to be a systems integrator – just mount, connect, and commission.

What’s in the Kit

Each Sinoah G3 Single Phase ESS Kit includes everything needed for a complete home storage installation:

· 1 × G3 Single Phase Hybrid Inverter (3.6kW, 5kW, 6kW, 8kW, or 10kW – model depends on kit)

· Stackable LiFePO4 Battery Modules (2–4 × 7kWh or 14kWh modules depending on configuration)

· Pre-made power and communication cables

· Mounting base and stacking hardware

· CT clamp and meter for system monitoring

The inverter and batteries arrive in a single consolidated shipment from Sinoah Energy’s UK warehouse – no multiple deliveries, no missing components, no compatibility surprises.

Examples of Available Configurations

Why Choose a G3 Kit?

1. Pre-Matched, Pre-Tested, Ready to Install

Every G3 kit is factory-tested as a complete system. The inverter and batteries communicate seamlessly via CAN bus – no compatibility issues, no firmware conflicts. Installers save hours on each job, and homeowners get a system that works from day one.

2. One Box, One Shipment, One Warranty

The entire kit ships from our UK warehouse in a single delivery. No multiple suppliers, no partial shipments, no compatibility guesswork. One point of contact for warranty claims – we handle everything.

3. Genuine LFP Chemistry with 8000+ Cycles

The G3 battery modules use prismatic LiFePO4 cells – intrinsically safe, with no thermal runaway risk. With 8000+ cycles to 98% depth of discharge, these batteries deliver decades of reliable service.

4. Built for UK Weather

IP66-rated battery modules (IP65 for inverters) and self-heating technology for -20°C charging mean the system performs reliably in unheated garages, external walls, and exposed locations – no special enclosures required.

5. G99 Certified, UK Grid Compliant

All G3 kits are G99 certified and listed on the ENA Type Test Register – full UK DNO compliance with no commissioning delays.

6. Smart Tariff Optimisation

The integrated EMS enables intelligent charge/discharge scheduling aligned with time-of-use tariffs like Octopus Go. Charge overnight at 9p/kWh and discharge during peak 28p/kWh periods – saving hundreds of pounds annually.

7. VPP and FCAS Ready

Future-proof your investment – G3 kits are compatible with Virtual Power Plant and Frequency Control Ancillary Service programmes, enabling future revenue streams as the UK energy market evolves.

8. 10-Year Warranty

Both the inverter and batteries come with a 10-year warranty – one of the longest in the UK residential storage market.

Real-World Application: The 4-Bedroom Home with EV

A 4-bedroom detached home in the South East with a 6kWp solar array, an electric vehicle, and annual consumption of 6,000kWh. The family is on Octopus Go – 9p/kWh overnight, 28p/kWh during peak hours.

Installing the Sinoah G3 6kW / 42kWh ESS Kit transforms their energy economics:

Summer scenario – The 6kWp array generates 25–30kWh on sunny days. The 42kWh battery stores surplus solar (15–20kWh) for evening use and overnight EV charging. Grid import drops to near zero on sunny days.

Winter scenario – Solar generation drops to 3–5kWh per day. The 42kWh battery charges overnight on the 9p/kWh rate and discharges during peak periods. The system stores enough energy to cover 3–4 days of normal consumption.

Annual savings – Combined solar self-consumption and tariff optimisation deliver £1,000–£1,400 in annual bill savings. With the kit priced competitively, the payback period is 6–8 years – well within the 10-year warranty.

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

“From order to completion was 2 weeks... As for the hardware: battery and solar PV and inverter: They just work. No comments.” – Sinoah user, Whirlpool Forums

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

From an Installer’s Perspective

We asked a UK MCS-certified installer who has fitted multiple G3 systems what makes the kit approach different:

“The big thing is time. With a kit, everything is pre-matched – the CAN communication works out of the box, the voltage ranges are already set, and the mounting hardware is all in one box. I don’t need to spend an hour checking compatibility or two hours on the phone with tech support. That saves me half a day on each job.”

Installation speed – A complete G3 kit (inverter + batteries + solar connection) typically takes 4–6 hours for an experienced installer.

Weight and handling – Each 14kWh module weighs 128kg – manageable with two people. The floor-stacked design means no wall-mounting complications.

Commissioning – The inverter‘s LCD display and NeoVolt App guide installers through setup in under 30 minutes. Select the battery capacity, set the grid standard (G99), and the system is ready.

FAQs:

Q1: Can I expand the system later?

A: Yes. The modular design allows easy expansion – add battery modules as your needs or budget allow, up to 56kWh. No rewiring or system replacement required. Simply stack additional modules on top and plug in the pre-made cables.

Q2: Is the G3 kit suitable for homes without solar panels?

A: Yes. The system can charge overnight on cheap off-peak tariffs (e.g., Octopus Go at 9p/kWh) and discharge during peak periods (28p/kWh) – delivering significant bill savings through tariff arbitrage alone, without any solar input.

Q3: How does the G3 kit compare to the G4 series?

A: G3 kits offer 2 MPPT trackers, IP65 inverter rating, and sub-10ms UPS switching – ideal for most UK homes. G4 kits offer 4 MPPT trackers, IP66 inverter rating, and sub-4ms UPS switching – better for complex roofs and exposed installations. Both deliver the same 10-year warranty and 8000+ cycle battery life.
