Sunsynk published a news post on 18 April 2023 introducing the UK Mini Beast, a dual MPPT hybrid inverter. The post describes a unit built around a 7,000 Watt dual MPPT and a 3,600 Watt battery charger1.
The headline figures given by the maker are set out below.
| Feature | Rating as published |
|---|---|
| Dual MPPT | 7,000 Watt |
| Battery charger | 3,600 Watt |
| On grid inverter | 3,600 Watt, upgradable to 4 kW |
| Off grid inverter | 3,600 Watt |
| Auxiliary output | 3,600 Watt, for heating and hot water or controlling micro inverters |
The auxiliary output is described as being for heating and hot water or for controlling micro inverters1. The unit is listed with a full colour LCD and is stated to work with the Sunsynk Connect app or the Sunsynk portal1. Sunsynk also states that the unit is "Simply plug play and connect to CT coil"1.

The announcement does not give a price, a release date, a warranty term, an efficiency figure or a list of supported battery models. Those details have not been reported in the post. The post also does not state whether the 4 kW on grid upgrade is a firmware change, a model variant or a setting, and it does not define the conditions under which the auxiliary output operates.
Why it matters for households
A hybrid inverter sits between a home's solar array, its battery and the grid, deciding where power flows at any moment. The ratings published here set the ceiling on what a property could run and store. A 7,000 Watt dual MPPT input indicates two independent solar strings can be connected, which matters on roofs where panels face different directions or sit under partial shade. The distinction between string and hybrid inverters is the difference between a system that only generates and one that can also store and supply the home during a grid outage.
The 3,600 Watt battery charger figure indicates the rate at which a connected battery can be recharged from the grid or solar, and the 3,600 Watt off grid output indicates the load the unit can carry without grid support. The auxiliary output, rated at 3,600 Watts for heating and hot water, points to diverting surplus generation into a hot water cylinder rather than exporting it. For a household weighing up Sunsynk hybrid inverters and batteries or comparing all in one battery systems, the published ratings are the starting point for judging whether a unit matches a home's peak demand and daily consumption. How a battery is managed once connected is covered in battery management systems.
