1-4.6kW AC Coupled Inverter

1-4.6kW AC Coupled Inverter
Product Description
Sunplus AC Coupled Inverter (1kW-4.6kW) suitable for both single-phase & three-
phase systems. It can be fitted alongside string inverter, enabling you to
upgrade to solar battery storage system without changing your current
installation.
AC Coupled Battery Inverter Solution
An ac coupled battery inverter is perfect if you have an existing photovoltaic
array and want to add energy storage. It's simple - AC coupling uses a normal
solar inverter coupled to a battery inverter/charger to manage the battery
storage unit.
In an AC-coupled system, the DC power from the PV array is first converted to
AC by the PV inverter and then used to power the AC load panels. Any unused
energy is directed by the inverter/charger to charge the storage unit. In a
grid-tied system, when the grid fails, the inverter/charger isolates the base
load panel and PV inverter from the grid through an internal transfer switch.
This allows the PV array to generate electricity even during grid outages.
An AC-coupled setup is simple and powerful, but charging is slightly less
efficient than a DC-coupled solution. However, they are very efficient at
powering AC loads during the day and can be expanded with multiple solar
inverters to form a microgrid.
