8kW Single Phase Hybrid Inverter

The 8kW Single Phase Hybrid Inverter is the mid-capacity model in the G4 series. It converts 16kW of permitted DC input into 8kVA of single-phase AC output at 230Vac, stores surplus generation in a low-voltage LiFePO4 battery bank, and supplies a protected backup circuit when the grid is interrupted.

The unit is built for installations where roof space is split across several planes or where a garage and main roof are combined, which is why it carries four MPPT trackers rather than two. Sinoah Energy supplies it from UK stock with grid certification for UK connection, and the enclosure is rated IP66 so it can be mounted outside or in an unheated outbuilding.

Why Four MPPT Trackers Matter

A tracker is a separate power stage, and each one finds its own maximum power point for the strings connected to it. With four trackers the array is divided into four independent groups, so shading on one roof plane, a different tilt on an extension roof, or panels facing east and west do not drag down the rest of the system.

On UK housing stock this is the difference between a design that works on paper and one that produces through the day. A typical four-tracker layout on this unit is: main roof south string on tracker one, extension roof on tracker two, garage roof on tracker three, and a second south string on tracker four. Each string is monitored separately in the app, so underperformance on one plane is visible without a site visit.

Technical Specifications

Sizing an 8kW System

The 8kW Single Phase Hybrid Inverter suits a house with a heat pump, an EV charger and normal domestic demand, where the peak load sits between 6kW and 8kW. Because the DC input limit is 16kW, the array is normally specified between 8kWp and 12kWp, which lifts winter generation without exceeding the export limit.

Battery capacity is chosen from evening and overnight consumption rather than from the inverter size. On this unit the battery bank runs between 80V and 486V with a 60A charge and discharge current, which allows a stack of low-voltage modules to be sized in 7kWh steps and extended later without replacing the inverter.

EV Charging and Load Management

An 8kW inverter is often specified where an EV is charged at home. The inverter does not charge the vehicle directly; instead it manages the house supply so that battery discharge, solar generation and grid import are balanced against the total load. Time-of-use tariffs can be set in the monitoring app so the battery charges overnight at the cheap rate and discharges during the evening peak.

The 15kVA bypass path allows the full incoming supply to pass through the unit while it is operating on grid, so a high-current load such as a car charger or an electric shower does not have to run through the inverter electronics.

Applications

The 8kW Single Phase Hybrid Inverter suits detached and larger semi-detached homes with multi-plane roofs, heat pumps and EV charging.

Homes on time-of-use tariffs that need enough battery throughput to cover the evening peak.

Properties with outbuildings, where the IP66 enclosure allows mounting outside the main house.

UK Grid Compliance and DNO Notification

The unit is certified to G98 and G99, so the installation can be registered with the distribution network operator under the standard route. Typical single-phase domestic connections fall under G98 where the inverter output stays within the 16A per phase limit, while larger configurations follow the G99 process.

Sinoah Energy provides the certification documents with the unit so the installer can complete the notification. Where a project needs a specific grid code, that setting is selected during commissioning and recorded in the handover documents.

Why Choose Sinoah Energy

Sinoah Energy is a UK-based supplier of LiFePO4 batteries and hybrid inverters, holding stock in the UK for dispatch to installers, dealers and trade partners rather than shipping each order from the factory. Products are manufactured by NeoVolt with more than ten years of inverter production experience, and support is provided locally.

Trade customers get dealer pricing on monthly supply, branded or ODM units where a project needs them, and training for installation teams. Diagnostics run through the monitoring app, and any hardware fault is settled under warranty from UK stock.

Monitoring, Firmware and Service Support

The unit reports generation, battery state of charge, backup load and per-string performance to the monitoring app over WiFi or LAN, with Bluetooth available for commissioning on site. Firmware updates are delivered to the inverter and to the battery management system through the same link, so a fix or a new grid code does not require a site visit.

Where a fault is logged, the app shows the event and the affected string or module before the installer arrives. Sinoah Energy runs remote diagnostics on returned event logs, and where a hardware fault is confirmed the replacement is issued from UK stock under the 10-year warranty.

FAQ

Q: How many panels can be connected to the 8kW Single Phase Hybrid Inverter? 

A: The DC input limit is 16kW, so the array is normally 8kWp to 12kWp spread across four strings on four trackers.

Q: Can two roof orientations be tracked separately? 

A: Yes. Four independent trackers mean east, south, west and outbuilding arrays can each run at their own maximum power point.

Q: Does the inverter charge an electric vehicle? 

A: It does not charge the vehicle directly. It manages the house supply so that solar, battery and grid import are balanced against the total load, including a car charger.

Q: How much battery can be connected? 

A: Battery voltage range is 80V to 486V with 60A charge and discharge, which accepts the Sinoah Energy low-voltage modules in 7kWh steps up to 56kWh.

Q: Is it suitable for outdoor mounting? 

A: Yes, the enclosure is IP66 and rated from -25C to +60C, so an outbuilding or sheltered external wall is acceptable.

Q: What warranty covers the unit? 

A: 10 years, with warranty support handled from the UK and delivery from UK stock.
