SolaX single-phase X1 BOOST

Presentation: SolaX single-phase X1 BOOST

SolaX has developed an industry-unfazed inverter range unmatched for quality, reliability and efficiency. SolaX single-phase inverters offer a wide range of MPPT voltage to allow for better energy recovery and have a maximum input voltage of 600V, with a maximum efficiency of 98%. In addition, SolaX single-phase inverters are IP66 compliant, do not have an internal fan, and come with the optional "Plug-Play" Wi-Fi.


Perfect for residential photovoltaic panels

The X1 Boost is the ultimate residential solar inverter, perfectly designed for homes with solar panels on different sides of the roof. With two MPPT trackers, the X1 Boost can be connected to two separate panel arrays, our X1 Boost is also rated IP66, which means it can be installed outdoors.

Simple, Reliable, Efficient

The SolaX X1 Boost is one of the most efficient residential solar inverters available on the market today, offering a massive efficiency of 98% and with a maximum CC voltage of 600V, you can make sure you get the most out of your solar energy.


Install indoors or outdoors

The X1 Boost is rated IP66, which means it can be installed indoors or outdoors, giving you the option to choose where to install the system.
