Sunsynk published a news post on 27 April 2023 introducing a 3.6kW hybrid inverter it calls the "Mini Beast". The maker says the unit has a dual MPPT input and can handle up to 7000W of solar energy, which it states makes it possible to charge batteries and power a home at the same time1.
The company lists the following features for the product1:
| Feature | Detail as stated by Sunsynk |
|---|---|
| Display and enclosure | Colourful touch LCD, IP65 protection degree |
| Coupling | DC couple and AC couple to retrofit existing solar systems |
| Parallel operation | Max. 16 inverters in parallel; supports multiple batteries parallel |
| Charging and discharging | Max. charging/discharging current of 90A |
| Scheduling | 6 time periods for battery charging/discharging |
| Generator input | Support storing energy from diesel generator |
| Warranty | Warranty included |
Sunsynk describes the unit as working both on and off grid, and says it reduces energy bills while providing uninterrupted power1. The post does not give an efficiency figure, a price, a warranty length in years, a weight or dimensions, or a date for availability in the UK. Those details have not been reported in the announcement1.
"This trusty little inverter works on and off grid to reduce your energy bills while providing uninterrupted power!"
The post directs interested parties to contact a distributor for more information, and does not name any distributor or installer1.
Why it matters for households
A hybrid inverter sits between a home's solar array, its battery and the grid, deciding where generated electricity goes at any moment. The 3.6kW figure is the inverter's rated output, while the 7000W figure is the amount of solar input Sunsynk says the unit can accept, so a household could in principle fit more panel capacity than the inverter's output rating. The dual MPPT input means two separate panel strings can be connected and tracked independently, which matters where a roof has sections facing different directions or shaded at different times of day. More on how these units differ from standard string inverters is set out in our guide.
The stated ability to DC couple and AC couple is relevant to homes that already have solar installed: AC coupling allows a battery and hybrid unit to be added alongside an existing inverter rather than replacing the array's original equipment. The parallel capability, up to 16 inverters, and support for multiple batteries, point to systems that can be expanded over time rather than sized once. The 90A charging and discharging current and the six daily time periods for battery charging and discharging relate to how quickly a battery can be filled or drawn down and how a household schedules that activity around tariffs and peak periods. Sunsynk's wider UK range and warranty terms are covered in our Sunsynk inverter guide, and the manufacturer's other products in our Sunsynk section.
The diesel generator input is unusual among domestic hybrid inverters and is aimed at properties where grid supply is unreliable or absent, allowing a generator to charge the battery rather than only supply loads directly.
What happens next
No UK launch date, pricing or certification details were given in the announcement, and no distributor was named1. Sunsynk's post says only that households should contact a distributor to find out more1.
