3.1 Basic Features
H3/AC3 series are high-quality inverters which can convert solar energy to AC energy and store energy
into battery. The inverter can be used to optimize self-consumption, store in the battery for future use or
feed-in to public grid. Work mode depends on PV energy and user’s preference.

• System connection diagrams
Note: According to Australian safety requirements, the neutral cables of the on-grid side and backup
side must be connected together. Otherwise, the backup function will not work.
This diagram is an example for an application that neutral connects with the PE in a distribution box.
For countries such as Australia, New Zealand, South Africa, etc, please follow local wiring
regulations.
