Sunsynk announced its Hybrid Fusion Inverter range in a news article dated 23 September 2023. The range is described as an all in one unit combining a hybrid inverter and a LiFePO4 battery, with the smallest size given as a 2.5 kW single phase inverter and the largest as a 30 kW single or three phase inverter1.
The article lists three matched 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. Battery cycles are given as over 6,000, and the unit is said to support a 50% overload surge1.
The feature list covers grid interaction, backup and control. The unit is stated to be bi directional, on grid, able to AC couple, and to include an export limiter and time of use settings1. Off grid use and UPS use on a separate output are listed, along with the ability to control a generator set1. Built in items include an earth bond relay, an AC protector MCB, a solar isolator, a CT coil, and a battery isolator and fuse1. Solar input is given as two strings with an MPPT solar charger that can be oversized, plus surge protection1. Communications and monitoring include Can bus control, a MODBUS controller, remote monitoring, remote setting, and WiFi through Sunsynk Connect1. The unit is described as prewired and as needing only a mounting bracket fixed to a wall, with no other parts required1.
"Hybrid inverter and life po4 battery all in one"
The article also states that the unit can be paralleled, that parallel units can be mixed and matched, and that extra batteries can be added1. It lists a full colour LCD, plug and play AC and UPS connections, an external replaceable cooling filter, and overload, over temperature and under temperature protection1. It states "Octopus comparability Yes" without further detail1.
| Inverter | Battery |
|---|---|
| 2.5 kW | 2.1 kWh |
| 3.6 kW | 3.8 kWh |
| 5.5 kW | 5.2 kWh |
Why it matters for households
An all in one unit puts the inverter, the battery and much of the associated switchgear in a single enclosure, which is the arrangement described here: prewired, with the isolators, fuse, CT coil and AC protection built in1. For a household, that shape of product affects how much separate equipment has to be housed and wired, and how much of the installation is done before the unit reaches the wall. The stated ability to add extra batteries and to parallel units, including mixing and matching, bears on whether a system can be enlarged later rather than replaced1. Time of use settings and an export limiter relate to how a home draws from and sends to the grid, while off grid and UPS outputs on a separate supply relate to what keeps running during an outage1. The article does not give prices, warranty terms, efficiency figures or a UK availability date, and none of these have been reported in it1.
What happens next
No next steps, launch dates or availability details are given in the announcement1.
