In contrast, the Fronius Symo Gen24 Plus will be for three-phase applications and can be seen as a considerable upgrade from the Symo Hybrid, which is currently on the market for only three-phase applications. The Symo Gen24 Plus will be offered in three versions, ranging from 6-10 kW of output power for loads and charging.
The Gen24 Plus has great flexibility for planning your solar array. Both inverters have a high input voltage range, where the Primo Gen24 Plus can accept up to 530 V of solar input per Maximum Power Point Tracker (MPPT) for their 3-5 kW versions and the Symo Gen24 Plus can accept up to a whopping 800 V per MPPT for all three versions. Such high voltages allow for flexibility in incorporating high voltage and solar efficiency solar panels with a larger number of photovoltaic (PV) cells (i.e. 96 or 144 cells). These inverters have a single DC output for batteries.
Both inverter classes (Primo and Symo) now carry two MPPT trackers, allowing for flexibility for solar array layouts. A single MPPT tracker would restrict the layout of the solar array to a single uniform orientation.
They have internal cooling that is automatically regulated which is great for long term reliability and efficiency of the units. They have a smaller form factor as well where the Primo Gen24 Plus is 36 pounds and the Symo version is 53 pounds.
The Primo and Symo Gen24 Plus will have versatile onboard communication that can communicate with the battery system, charging infrastructure of electric vehicles, home appliances, and many more, for storage efficiency. The origin of this versatility derives from the ability to implement buffer parameters to keep batteries charged sufficiently supplying critical loads when needed most – a crucial feature we typically see in load controllers. Even more, Gen24 Plus has a user-friendly setup procedure that can be used on any smartphone or tablet.
They will carry a “PV Point”, which is a direct plug-in on the inverter which provides AC backup capabilities when the grid is out. Even more, PV point application can operate with or without batteries and will supply at the same rate of the output power of the inverter, creating a robust buffer to supply important loads.
The Gen24 Plus will also have a simple installation procedure. It will be installed on a wall mount system, where a wall-mount is connected to a wall, and the inverters are mounted on the wall-mount with quick-release screws. They will also have spring connections that will allow for easy cable installation, where the cables can be simply inserted into a spring-powered clamp.
The only potential downside we see to the Gen24 Plus inverter is its limited battery compatibility. The Gen24 Plus series is reported to only be compatible with the “BYD Battery-Box Premium HVS/HVM.” This is a high voltage battery that is not as common in the residential storage market as 12-48V batteries. The Gen24 Plus series has input battery specifications that are only compatible with high voltage batteries, which limits the battery choice if customers ever decide to stray away from the BYD battery it is advertised to work with.
