This is an ideal system for customers looking for a high-quality, easy-to-use solution. It fully integrates solar PV, battery storage, electric vehicle charging and intelligent control of household devices, providing a simple and seamless energy management system for the home. The gateway is compatible with third party EV chargers, generators and hot water diverters.

EcoFlow is a relatively new entrant to the home battery market, having previously focused primarily on portable power and smaller systems for caravans and leisure applications. The system provides a maximum backup output of 55A, making it more suited to essential-loads backup rather than whole-home backup during a power cut.

The key differences between the EcoFlow PowerOcean 2 Plus and the EcoFlow PowerOcean 2 are the additional MPPT solar inputs, providing greater flexibility for connecting and managing multiple solar arrays, and the larger inverter capacity, allowing higher charge and discharge power. It also features integrated essential-loads backup, providing power to selected circuits during a power cut. No bi-pass switch in the gateway so if the gateway stops working an electrician needs to be called to restore power (unless an external changeover switch is installed). The gateway is compatible with generators.

From the manufacturer of the largest EV manufacturer in the world. The BYD Battery Box is compatible with many inverters, making it more easy to repair in the future. Also has a BYD AC EV charger. The backup gateway is only 63A, so is only suitable for very small homes or for use as essential loads backup.

Sungrow have a device called an EnergyBridge which is a very small backup gateway, but it is limited t0 80A.

This system is well suited to installations where the battery can be located close to the incoming supply, where the energy supplier’s meter is situated.

Its main difference from the SigenStor EC is that it has an integrated backup system, making it a lower-cost option. However, its key limitation is the lower 63A power cut backup output, which may not be sufficient to supply all of the electrical loads in some UK homes. It effectively offers essential loads power cut backup which requires a new consumer unit.

Sungrow are extremely popular in Australia due to their competitive pricing. The EnergyBridge is a micro backup gateway meaning it is installed in a normal consumer unit (rather than needing a large box).  However, the EnergyBridge does not have the features of some of the gateways such as smart control of generators, control of third party EV chargers and is missing a very important bi-pass switch.
