MARSTEK MARS I PLUS Three-Phase – 8 to 12 kW Hybrid Home Battery System

The MARSTEK MARS I PLUS Three-Phase is an advanced all-in-one energy storage solution for residential and light commercial use. It combines a three-phase hybrid inverter, high-voltage battery technology up to 1000 V, intelligent energy management and extensive expansion options into one powerful system.

Designed for maximum efficiency, flexibility and long-term reliability.

Powerful Three-Phase Hybrid Inverter (8–12 kW)

The MARS I PLUS is available in 8 kW, 10 kW and 12 kW versions and is perfectly suited for homes with higher energy demand or three-phase grid connections.

It enables:

• efficient solar energy conversion

• intelligent battery charging and discharging

• stable grid interaction

• preparation for off-grid operation

Up to 24 kW Solar Input with 4 MPPTs

Thanks to four independent MPPTs, the system supports up to 24 kW of PV input, ensuring maximum solar yield even with multiple roof orientations or partial shading.

1000 V V-Boost Battery Technology

The advanced 1000 V V-Boost architecture ensures:

• higher efficiency

• improved energy balance

• reduced losses

• longer battery lifespan

Each cell is actively balanced to deliver optimal long-term performance.

Expandable to 30.72 kWh – Scalable to 122.88 kWh

The system supports up to 6 battery modules, providing 30.72 kWh of usable storage per unit.

Up to 4 systems can be connected in parallel, allowing:

• up to 48 kW output

• up to 122.88 kWh total storage

Ideal for large homes, villas or small commercial installations.

Intelligent Energy Management with AI Optimization

The built-in Energy Management System analyzes:

• electricity prices

• consumption patterns

• solar production

• battery status

AI-based Time-of-Use optimization automatically charges during low-cost periods and discharges during peak prices.

Anti Feed-In with Smart Meter Integration

The system prevents unwanted grid export by storing surplus energy locally.
This maximizes self-consumption and reduces dependency on the grid.

EPS Backup Power (<10 ms)

In case of grid failure, the system switches to backup mode in less than 10 milliseconds, ensuring uninterrupted power for critical loads.

Generator support is also available.
