ATMOCE M-ELV 7 kWh Battery | MS-7K-U<\/strong><\/h2>\n

The ATMOCE M-ELV MS-7K-U 7 kWh battery<\/strong> is an AC-coupled<\/strong> energy storage solution designed to improve energy utilisation and simplify the addition of battery storage to existing photovoltaic installations. Its compatibility with third-party PV and energy management systems allows storage to be added while retaining the existing inverter, depending on the installation configuration.<\/p>\n

It incorporates lithium iron phosphate (LFP) cells<\/strong>, a maximum internal voltage of 28.8 V DC<\/strong> and galvanic isolation between the battery and the grid. The same model can be integrated into single-phase and three-phase installations<\/strong>, with a maximum continuous output power of 4.5 kVA<\/strong> and a maximum output power of 5 kVA<\/strong>.<\/p>\n

\n

Select the appropriate energy management kit<\/strong><\/p>\n

To integrate this battery with an existing inverter, the ATMOCE MA-ESSKits-S kit for single-phase installations<\/strong> or the MA-ESSKits-T kit for three-phase installations<\/strong> is required. These kits are sold separately. For backup power during grid outages, the M-Backup MU100-S or MU100-T<\/strong> must also be added, depending on the installation type.<\/p>\n<\/div>\n

Key features<\/h3>\n
\n
\n

7 kWh of energy storage<\/strong><\/p>\n

A nominal capacity of 7 kWh for storing energy and using it when photovoltaic generation and consumption do not coincide.<\/p>\n<\/div>\n

\n

AC coupling<\/strong><\/p>\n

Integration with third-party photovoltaic systems to add storage to existing installations, depending on the system design.<\/p>\n<\/div>\n

\n
