Combo Technical Specifications

The MUST battery has a manufacturer-rated 15.36kWh nominal energy capacity, 300Ah capacity, 51.2V nominal voltage and up to 200A continuous charge/discharge current. The Growatt SPE 12000 ES provides 12kW output, dual MPPT tracking, generator support and low-voltage battery compatibility.

High-Capacity Solar Backup System South Africa

This 12kW inverter and 16kWh lithium battery combo is well suited to larger properties where smaller 5kW or 8kW systems may not provide enough inverter capacity or battery storage.

Depending on the final system design and connected loads, the combo can support substantial household or business energy requirements while storing solar energy for use when solar production drops or grid electricity is unavailable.

The MUST battery's 15.36kWh nominal storage capacity provides a large energy reserve, while the Growatt's 12kW inverter output gives the system the ability to support significantly higher instantaneous loads than smaller residential inverter systems.

Ideal for Solar Panels, Lithium Battery Storage & Backup Power

The Growatt 12kW hybrid inverter can manage solar panels, batteries, grid electricity and generator input, while the MUST LiFePO4 battery stores energy for later use.

This makes the combo suitable for:

• Large home solar systems
• Business solar installations
• Solar battery backup
• Load-shedding backup
• Off-grid solar systems
• Solar self-consumption
• Farms and workshops
• Commercial backup power
• Renewable energy storage

Actual backup time depends on connected load, usable battery capacity, inverter efficiency, battery settings and operating conditions.

Smart WiFi Monitoring

The MUST 16kWh-class battery includes a built-in WiFi Smart BMS and LCD display, allowing important battery information to be monitored locally and remotely.

The Growatt inverter also supports WiFi and 4G monitoring, helping users keep track of their solar and backup system performance.
