The 3 phase fronius-symo-hybrid-5-0 has a inbuilt battery charge/controller/manager to seamlessly connect batteries. Like all Fronius products, the design, workmanship and quality is the best on the market. Unfortunately the Hybrid is only available in 3 phase at the moment. The single phase will be out late 2019.
The Fronius Symo Hybrid 5.0 inverter, combines a battery charging system, battery inverter, hybrid inverter, controller and system monitoring solution in one device. With AC power categories ranging from 3.0 to 5.0 kW, the inverter is able to process up to 8.0 kW in order to supply household consumers with energy and to temporarily store surplus energy from a photovoltaic system into battery systems. Thanks to an intelligent energy flow management system, the built-in Multi Flow Technology supports simultaneous energy flows in all directions as well as AC-, DC- and AC- & DC coupling of the battery storage. The result: maximum self-consumption and optimum system profitability.
The Fronius Symo Hybrid 5.0 is best suited to the LG Chem HV range via a small Fronius Check box. Like all Fronius products the analytics is seamless in the Fronius Solarweb. You can easily see the systems production, the battery levels and battery discharge.
If you have a 3 phase connection to your home and not currently have solar, then the Fronius Symo Hybrid 5.0 is the best option on the market, and combined with LG Chem, you have premium quality and reliability.
