Can ESS work with a grid-tie PV inverter?

PV (optional) ESS can work with both Grid-tie PV inverters and/or MPPT Solar Chargers. (A mix of both is also possible.) When using Grid-tie PV Inverters we recommend monitoring is performed using the CCGX. See CCGX manual for the options. ESS can also be operated without PV.

The ESS mode is configured to 'Keep batteries charged'. When using a grid-tie inverter, it is connected to the AC output as well. When grid power is available, the battery will be charged with power from both the grid and the PV. Loads are powered from PV when that power source is available.

Can ESS be combined with Fronius smart meter?

By using the "Power Reduction" feature in Fronius grid-tie inverters, the ESS system can automatically reduce the output of the installed PV inverters as soon as feed-back is detected; without switching and frequency shifting. It is not possible to combine ESS with the Fronius Smart Meter, but it's not necessary either, as ESS already has metering.

Can ESS be used without a grid meter?

ESS can be used with or without an external grid meter. Where there is a grid meter, either a full or partial grid-parallel system can be configured to run alongside. Where there is no grid meter, all loads are connected to AC-out. This also applies to a PV Inverter that is also connected to AC-out.
