2.2. THE INVERTER CAN SWITCH CIRCUITS IN AND OUT BY CONTROLLING RELAYS
In addition to the grid connection of the Sunsynk inverter, the LOAD connection and a GEN/AUX
connection are basically all the same, but they are switched IN and OUT via a number of relays.
IMPORTANT:
Note the inverter can only do one thing at a time: you can either charge the batteries using the inverter or
discharge the batteries using the inverter. If you are charging the batteries, you must be connected to a
generator or an AC load to have a source of power to charge the batteries. This works separately from the
MPPT, which will also charge the batteries if the MPPT/solar supplies power to the inverter.

2.3. UNDERSTANDING HOW THE INVERTER OPERATES IS ESSENTIAL WHEN SELECTING
THE CORRECT WIRING CONFIGURATIONS
If you press the bar chart on the inverter's display, it will come up with a screen showing the flow of power
within the inverter. This is very useful and very unique to the Sunsynk inverter. The most important thing about
a hybrid inverter is the battery and its ability to store/provide power when needed.
