4.0 Overview
4.1 Functional Overview
This pure sine wave hybrid i nvert er charger with solar charge controller (MPPT) can provide power to c onnected
loads by utilizing PV power, AC power and battery power.Most connections are optional, but there must be at least
one power source (AC or PV):
Fig. 1: System Overview
This unit has one each of the following power connections: battery, PV,AC input, AC output. The unit is designed to
provide cont inuous power from PV / battery or an AC source, depending on the set p riority. Independently, the
priority for charging the battery can be set (the battery can only be charged from AC when the unit is not working in
Off-Grid mode). The switchingtime between Grid (also validwhen an AC generatoris used) and Off-Gr id modes is
only 10 milliseconds (typical) when a single Any-Grid unit is used.Timers canbe used to c hang e the prioritiesbased
on hourly time slots; t his is useful for areas where grid power has differingcos ts throughout the day.The integrated
maximum power point tracking (MPPT) solar charge controller can handle particularly high PV voltages, allowing for
a simpler installation and lower costs than mos t Off-Grid solar charge controllers. Typically, no combiner boxes or
str ing fuses / diodes are required.
The pure sine wave AC output and the surge power capability (twice the continuous power rating) ass ure all types of
AC loads can be powered. Ensure that the peak power requirement of the loads is below the surge power capability
of this inverter.
Two spec ial functions allow even more flexibility: Battery-Free mode and Grid Injection.
In Battery-Free mode,nobattery is conne cted to the unit and an AC source must be present.The unit will then
provide as much power from PV as is available to supply loads, adding any missing power from the AC source. If there
is more PV power available than can be utilized by the loads, thenthe PV power is reduced to ensure no power feed-
in into the grid.
The Grid Injectionfunctionality allows fee ding any excess power into the grid. If there is excess PV power beyond
what is utilized by the load and for battery c harging, this power can be fed into the public grid to takeadvantage of
net metering or feed-in tariffs. In this way all the PV power can be used even if the battery is full, and the loadsdo not
require all the available PV power. Feeding into the grid may be prohibited in some areas so this function is locked by
a PIN code to avoid accidental grid injection.
