Modular and flexible: The Quattroporte series

In some cases, two steps are required before autonomy is achieved: with the Quattroporte series, E3/DC has brought an upgrade solution for existing PV systems onto the market. The modularly expandable power accumulator has its own energy management system.

Compatible with the PV Inverter

A solution with two components

Unlike an all-in-one home power plant, the Quattroporte requires a solar inverter** for a PV system or an AC power generator to already be installed. Therefore, in principle, this storage system is suitable for any existing PV system, which the operator would like to use to produce considerably more energy himself, ranging from a small private installation with only a few kW of output to large generators on commercial roofs.

The Quattroporte is installed between the solar inverter and the home grid, as an AC system. The integrated battery inverter converts the grid-compatible current into battery-compliant direct current. During controlled discharge, the current is converted once again, and distributed to household consumers via the energy management system.

**Important information:
In older PV systems, the inverter may be nearing the end of its service life, while the module field will continue to provide power reliably for many years. In the event of an upgrade, it is therefore definitely worth considering a home power plant as an all-in-one accumulator solution – because the new inverter is part of the deal!

A fitting accumulator solution for every need

The application has an enormous range

To enable the installation of an efficient accumulator system for an existing plant of any size, the Quattroporte is available in the smallest versions (UNO), with capacities of 3.3 kWh and 6.5 kWh, and in the larger versions (DUE and MAX), which have a modular structure, made up of 6.5 kWh battery modules. The slim, vertically positioned DUE housing has sufficient space for between one and four modules, resulting in a maximum capacity of 26 kWh. For larger applications, two to three Quattroporte MAX XXL units can be combined to form a system, with a capacity of up to 86 kWh or 78 kWh.

In energy farming, any desired higher level of accumulator capacity can be realised till over 200 kWh. With up to three battery inverters (with a capacity of 1.5 kW each), a maximum charge/discharge capacity of 4.5 kW is achieved per Quattroporte housing. In a system network with up to nine inverters, the maximum capacity is 13.5 kW.

Future-proof through unlimited upgrade possibilities

Intelligent self-management of energy

The Quattroporte systems can be retrofitted for an unlimited period, and there is no limit to the number of cycles within the 10 year guarantee period. In the Quattroporte series, the connector module, which links all the battery modules, ensures efficient energy management.

Via this interface, the accumulator also controls the E3/DC wallbox and communicates with the home automation system and the energy portal. As an intelligent upgrade accumulator, the Quattroporte is therefore compatible with all commercially available inverters.
