6kW Single Phase Hybrid Inverter

The 6kW Single Phase Hybrid Inverter is a single-phase hybrid unit that manages solar generation, battery charging and backup supply from one wall-mounted enclosure. It accepts up to 12kW of DC input from the array, which allows substantial oversizing against the 6kW AC rating, and delivers 6kVA to the grid or to the backup circuit at 230Vac, 50/60Hz.

Sinoah Energy supplies this unit as part of its single-phase hybrid inverter range, manufactured by NeoVolt and configured for UK installations. The inverter works with low-voltage LiFePO4 battery modules, has two independent MPPT trackers for roofs with more than one orientation, and is rated IP65 for outdoor or outbuilding mounting. Grid certifications cover G98, G99, VDE-AR-N 4105, EN 50549-1 and IEC 62109.

What the 6kW Rating Covers

The 6kW Single Phase Hybrid Inverter rating refers to AC output. In practice the unit is sized from three numbers: the array installed, the load backed up, and the battery connected. With 12kW of permitted DC input the array can be twice the inverter rating, which keeps output high across the day and in low light rather than clipping at midday.

Backup output is rated 6kVA continuous with a 15kVA bypass path, so the unit can carry the essential circuits of a house and pass through grid supply above its own rating. Two MPPT trackers, each with one string, allow different arrays to be tracked separately, which matters on terraced and semi-detached UK roofs where panels are split across planes.

Backup and Grid Behaviour

When the grid fails, the unit transfers the backup circuit to inverter supply in under 10ms, which is fast enough that most domestic equipment does not restart. The backup output runs at 6kVA continuously and can pass 15kVA through the bypass path, so a house with a large incoming supply is not limited by the inverter rating during normal grid operation.

For grid connection, the inverter holds the power factor near unity and can be set between 0.8 leading and 0.8 lagging where the network operator requires it. Total harmonic distortion is held below 3% on both current and voltage, which keeps the installation inside the limits set by G98 and G99.

Applications

The 6kW Single Phase Hybrid Inverter suits semi-detached and terraced homes with split roof orientations, where two MPPT trackers recover generation from separate planes.

Homes adding battery storage to an existing solar array, using the 80-467V battery window to accept low-voltage LiFePO4 modules.

Whole-home backup for essential circuits such as heating controls, refrigeration, lighting and communications.

Installation Notes for UK Properties

The unit is wall-mounted and needs 300mm of clear space above and below for airflow, with the cooling fans kept clear of insulation. Cable entries accept standard glands, and the DC isolator and AC isolator are fitted externally to the enclosure as required by UK practice.

Commissioning is carried out through the mobile app over Bluetooth or the local WiFi connection, with the grid code selected from the certified list and the DNO notification details recorded. Sinoah Energy holds the unit in the UK warehouse so orders for installers and trade partners are dispatched from stock rather than from the factory.

Why Choose Sinoah Energy

Sinoah Energy supplies LiFePO4 batteries and hybrid inverters to the UK market from UK-held stock, with the technical and warranty support based in the UK rather than overseas. The inverter range is manufactured by NeoVolt, a Chinese power electronics manufacturer with more than ten years of inverter production experience, and each unit carries grid and safety certification for UK installation.

Support covers system design and capacity calculation before the order, compatibility checks against the battery modules, OEM or ODM customisation where a project needs it, and after-sales diagnostics through the monitoring app. Installer and dealer training is available, and warranty service is handled locally.

Load Shedding and Backup Circuit Design

A 6kVA backup output will not carry a whole house at once, and it is not intended to. The backup board is built around the circuits that have to keep running: heating controls, the fridge and freezer, lighting, broadband and a socket for charging phones. High-demand appliances such as a shower, oven or car charger are left on the non-backed-up side of the board.

Where the household wants a larger backup load, the inverter can supply up to 15kVA through the bypass path while the grid is present, and the backup board is then limited only by the incoming supply. The split between backed-up and non-backed-up circuits is decided at the design stage from the household's own list of essential loads.

FAQ

Q: How large a solar array can be connected? 

A: Up to 10kW of DC input. Oversizing raises output in low light and across the winter months without exceeding the AC limit.

Q: Which batteries work with the 6kW Single Phase Hybrid Inverter? 

A: Low-voltage LiFePO4 batteries with a system voltage between 80V and 467.2V. The Sinoah Energy stackable modules, including the 42kWh and 56kWh configurations, are matched to this range.

Q: Is the inverter certified for UK grid connection? 

A: Yes. Grid certification covers G98, G99, VDE-AR-N 4105, EN 50549-1 and IEC 62109, and the applicable grid code is selected during commissioning.

Q: Can it run without a battery? 

A: No. This is a hybrid inverter designed to work with a battery, and it is normally installed together with an LFP module or rack.

Q: What is the warranty and where is service handled? 

A: 10 years, with support and warranty service handled from the UK. Delivery is from UK stock for installers, dealers and trade partners.

Q: How long is the switching time to backup? 

A: Under 10ms, which keeps most domestic appliances running through a grid interruption.
