Is this Synchronous Buck Converter superseded by a better device ?

Every site that sells them don’t have the word “Synchronous”
In my RV I am running a hybrid low frequency inverter dc 48v to ac 5000w pure sine wave, a hybrid air-con straight off the 2000w of solar panel, a wind turbine 12v fridge x2 battery banks(3) consist of 12/24/48v lead acid, Gel & Lithium so I need good reliable step-down transformers thanks for your advice
