Sunsynk posted a news item dated 27 August 2023 setting out the features and battery pairings of its Hybrid Fusion Inverter range, an all in one product that combines a hybrid inverter with a lithium iron phosphate battery in a single prewired enclosure.
The item lists three inverter and battery combinations: a 2.5 kW inverter with a 2.1 kWh battery, a 3.6 kW inverter with a 3.8 kWh battery, and a 5.5 kW inverter with a 5.2 kWh battery1. Sunsynk states the smallest inverter array is 2.5 kW single phase and the maximum size is 30 kW single or three phase1. It gives battery cycles as over 6,0001.
The feature list covers grid tied and off grid operation, AC coupling, an export limiter, time of use control, a built in earth bond relay, a built in AC protector MCB, a separate UPS output, generator control, a full colour LCD, parallel operation including mixed parallel, additional batteries, CAN bus control, a MODBUS controller, remote monitoring and remote setting, WiFi through Sunsynk Connect, an MPPT solar charger that can be oversized, two solar strings, a built in solar isolator, surge protection, plug and play AC and UPS connections, an external replaceable cooling filter, 50 per cent overload surge, overload protectors, over and under temperature protection, an auto power saver, and an AC charger1. The item also states the unit is fully programmable and lists Octopus compatibility1.
On installation, Sunsynk says the unit is fully prewired and needs no opening, is mounted on a bracket fixed to the wall, and requires no other parts1. It states a CT coil, battery isolator and fuse are included1.
"Hybrid inverter and life po4 battery all in one"
The item does not give prices, warranty terms, efficiency figures, dimensions or a UK release date, and none of these have been reported in it1.
Why it matters for households
An all in one unit of this kind puts the inverter, the battery and the changeover equipment in one enclosure, which reduces the number of separate boxes on a wall and the wiring between them. For a household, the pairing figures matter because the battery capacity listed alongside each inverter is small by the standards of standalone home batteries: 2.1 kWh, 3.8 kWh and 5.2 kWh1. A battery of that size covers short outages and some evening load shifting rather than a full day of household demand, and the item states extra batteries can be added1.
The listed off grid and UPS output, separate from the main supply, is the part that speaks to energy independence: it indicates circuits can keep running when the grid is down1. Time of use control and an export limiter affect how the system interacts with a tariff and with the grid connection1. The item does not state whether the range is certified for UK grid connection or eligible for any grant or export scheme, and that has not been reported1.
What happens next
No next steps, dates or launch schedule are given in the item1.
