Frequently Asked Questions; Batteries

AC coupled solar battery systems connect directly to the switchboard. Possessing an internal battery inverter, AC-coupled solar batteries monitor solar production and grid energy flow with an additional monitoring device located in the switchboard to communicate when the battery should charge and discharge.


DC-coupled solar batteries connect directly to a nominated battery input on selected (usually hybrid) inverters. Due to communication compatibilities, DC-coupled solar battery systems are limited between selected brands. DC-Coupled batteries contain no internal inverter and are managed by the existing inverter with a connected power supply energy monitor.


All-in-one solar batteries are a DC-Coupled solar battery system within a box. This "box" contains almost everything to manage the solar and battery system. From a consumers perspective though, the box can be considered AC-Coupled, as it connects directly to the switchboard. However, batteries are always DC-Coupled internally (even on AC-coupled solar batteries).

Modern solar battery systems require a power supply energy monitor to tell the battery when to charge and discharge.


Most AC-coupled batteries include a power supply energy monitor.


Considering the majority of DC-Coupled batteries in a residential scenario will be connected to a hybrid (multi-mode) inverter, there is no power supply energy monitor included within a DC-Coupled battery package. This can be supplied at an additional cost though.


When installing a hybrid inverter with a solar package, it's best to install the power supply energy monitor at the time of the solar installation, ensuring the solar energy system is truly battery ready.

This all depends on you.


A solar battery has a limited storage capacity. If you exceed the storage capacity with energy consumption the battery will be unable to sufficiently provide energy offset.


PSW Sales Support can provide detailed bill reduction estimates based on your past energy usage patterns. Quite simply, the more power bills you provide including approximate time of day consumption habits, the more accurate our modelling data will be for you.

Quite Likely.


If you qualify for the Distributed Energy Buyback Scheme (DEBS) you can receive 0.03c off-Peak and 0.10c Peak for each unit (kWh) exported by your solar energy system.


As long as the battery is set to zero export and the solar inverter capacity isn't being increased above 5kW output capacity, it's quite likely (subject to Synergy approval) you'll still qualify for DEBS.
