This is our preferred inverter when installing solar and a battery at the same time. Instead of having an inverter and a separate battery management unit this has everything all in one compact unit. We use Pylontech 2.4kWh Lithium Ion batteries with this, our standard system includes one 2.4kWh but additional batteries can easily be installed either on installation or at anytime in the future, giving you the option to monitor your new system for a period of time and make an informed decision if extra capacity is necessary.
