5kW Single Phase Hybrid Inverter

The Sinoah 5kW Single Phase Hybrid Inverter is a DC-coupled, single-phase unit that connects solar PV arrays, battery storage, and the grid in a single compact housing. Unlike AC-coupled systems that require separate battery inverters, this hybrid design reduces component count, lowers installation cost, and improves overall system efficiency. The inverter intelligently manages energy flows – directing solar power to home loads, storing surplus in batteries, and only importing from the grid when necessary.

The unit features dual independent MPPT trackers, each accepting up to 15A of input current. This allows two solar strings with different orientations (e.g., east and west roof slopes) to operate at their individual maximum power points, capturing more energy across the day. With a maximum PV input of 10kW (200% oversizing), the inverter accommodates future solar array expansions without requiring replacement – a practical consideration for UK homeowners planning to add more panels.

Real-World Application: The 3-Bedroom Semi in the South East

Consider a typical 3-bedroom semi-detached home in the South East with a 4kWp solar array. During summer months, the solar system generates 15–20kWh per day – more than the household consumes during daylight hours. Without storage, the surplus (8–10kWh) is exported to the grid at a low export rate. With the 5kW Single Phase Hybrid Inverter paired with a 9.6kWh NeoVolt battery, that surplus is stored and used in the evening, reducing grid import by approximately 70%. During winter, when solar generation drops to 3–5kWh per day, the same system charges overnight on the cheap rate and discharges during the day, cutting electricity bills by 50–60%. The inverter’s 200% PV oversizing capability (up to 10kW DC input) means even on cloudy UK days, the system captures enough energy to keep the battery topped up.

From an Installer’s Perspective: What Makes This Inverter Different

We asked a UK MCS-certified installer who has fitted over 50 hybrid systems what matters most when choosing an inverter. His answer: installation speed, clear labelling, and reliable grid compliance.

This 5kW hybrid inverter addresses all three. The unit comes with clearly labelled terminals and a logical internal layout that makes AC and DC connections efficient. The mounting bracket is straightforward, and cable entry points are generously sized – critical when routing multiple solar strings and battery cables into the same unit. The inverter supports both new installations and AC-coupled retrofits, giving installers flexibility across different project types.

Grid compliance is non-negotiable in the UK. Every Sinoah 5kW Single Phase Hybrid Inverter is G99 certified, meeting the Energy Networks Association requirements for connecting generation equipment in parallel with public distribution networks. The inverter also complies with G98, VDE-AR-N4105, and EN 50549-1 standards, ensuring it can be commissioned without grid-approval delays. For installers, this means fewer site visits, faster commissioning, and happier customers.

Technical Specifications

The Sinoah 5kW hybrid inverter is IP65 rated, making it suitable for outdoor installation in garages, utility rooms, or even exposed locations. The natural convection cooling system means silent operation – no noisy fans, no moving parts to fail. The operating temperature range of -25°C to +60°C covers everything from a Northumberland winter to a heatwave in London.

Safety and Protection Features

The inverter includes comprehensive protection: PV string current monitoring, insulation resistance detection, residual current monitoring, PV reverse polarity protection, battery reverse polarity protection, anti-islanding protection, AC overcurrent and short circuit protection, DC and AC surge protection Type II, and remote shutdown capability. For installers, this means fewer callbacks. For homeowners, it means peace of mind.

FAQ:

Q1: Is this inverter G99 certified for UK grid connection?

A: Yes. The Sinoah 5kW Single Phase Hybrid Inverter is fully G99 certified and listed on the ENA Type Test Register, complying with G98, VDE-AR-N4105, and EN 50549-1. Your installer can proceed with DNO applications without compliance concerns. The 5kW output exceeds the 3.68kW G99 threshold, so G99 approval is required – and our certification makes that process straightforward.

Q2: How much money can this inverter save on electricity bills?

A: Through smart tariff optimisation, the inverter charges your battery overnight on cheap rates (e.g., 7–9p/kWh on Octopus Go) and discharges during peak periods (25–35p/kWh). For a typical household with a 9.6kWh battery, this can save £300–£500 per year – on top of solar self-consumption savings.

Q3: Will the inverter keep my home running during a power cut?

A: Yes – with the optional backup box installed. The inverter switches to battery backup in under 10 milliseconds, fast enough to keep routers, lights, fridges, and other essentials running. It provides 5kW continuous backup power (10kVA surge capacity), covering typical household emergency loads.
