6 Design of Graphic LCD Visualized icons to indicate the operation modes Optimized design on LCD allows user to understand the operational status at a glance MAX+ 1K/2K MAX+ 3K/5K Clear power flow between AC input, solar input, battery and loads Clear readings for Power/Voltage/Loading/ Battery

7 Operation Modes PV Power present Less PV Power No PV Power AC Input Power Present LINE MODE 2 LINE MODE 1 AC Input Power Absent BACKUP MODE 3 BACKUP MODE 2 BACKUP MODE 1

8 Operation Mode Line Mode LINE MODE 1 AC input power is present but there is no PV power (e.g. night time). Load is supplied by AC input power directly. LINE MODE 2 Both AC input and PV input are present. Load is supplied by either AC input or PV input depending on the priority switch s setting. Priority Setting Switch In LINE MODE 2, if priority setting is Solar first or SBU,and PV power is also strong enough to support load, the AC input will not be consumed even though it is present. This is deemed an energy-saving operation.

9 Operation Mode Backup Mode BACKUP MODE 1 Both AC input and PV input are absent. The backup power to load only comes from battery. The backup time is determined by the capacity of battery. BACKUP MODE 2 AC input is absentand PV power is not enough to support loads completely. The insufficient power is covered by battery. The larger PV power, the less consumption from battery and therefore the longer backup time. BACKUP MODE 3 AC input is absent and PV power is strong enough to not only support the load but also charge the battery. As long as the PV power persists, the load can be powered continuously without consuming power from battery extended battery run time

10 Standby Charging Mode When AC input cable (from AC mains or generator) and battery is connected, the inverter will enter into Standby Charging Mode and LCD will be turned on (as shown right). But if charger priority setting is only solar, utility won't charge battery. If PV string is also connected with enough voltage, the display will be as shown right to indicate the power flow from PV string. Except only solar setting for charger priority. Even if AC input is absent, PV power can still charge the battery and the display will be as shown right.

14 Configuration Highlight (1) Output Source Priority Solar first (default): Solar energy provide power to the loads as first priority. If solar energy is not sufficient to power all connected loads, battery energy will supply power to the load at the same time. Utility provides power to the loads only when any below condition happens: -Solar energy is not available -Battery voltage drop to either low-level warning voltage or the setting point. Utility first: Utility will provide power to the loads as first priority. Solar and battery energy will provide power to the load only when utility power is not available. SBU: Solar energy provides power to the loads as first priority. If solar energy is not sufficient to power all connected loads, battery energy will supply power the load at the same time. Utility provides power to the loads only when battery voltage drop to either low-level warning voltage or the setting point. It is deemed an energy-saving operation newly-added priority setting in MAX+
