APsystems ELT-12-EU – 12 kW 3-phase hybrid inverter

Modern energy management for maximum independence

The ELT series has been specially developed for residential solar installations and combines intelligent energy control, high safety standards and flexible application options. The system delivers up to 12,000 VA of power in normal operation and provides up to 18,000 VA in the event of an emergency power cut. This ensures that essential loads remain reliably supplied even during a power cut.

• 3-phase AC-coupled battery inverter
• For 48 V low-voltage batteries – particularly safe & easy to install
• Optimisation of self-consumption rate through intelligent PV management
• Emergency power & off-grid function for maximum supply reliability
• Real-time monitoring via the APsystems platform (EMA)
• Compact design – ideal for detached houses

Why choose the ELT series?

With intelligent energy management software, the system automatically adapts to your consumption profiles, solar output and – where available – dynamic electricity tariffs. This ensures you always use your solar power at the best time – for maximum savings and efficiency.

• Peak shaving: reducing peak loads to lower electricity costs
• Smart time control: charging when tariffs are low, discharging when prices are high
• Use more solar power: store during the day, use in the evening
• Easy retrofitting: Compatible with almost all existing PV systems
• Safe 48 V technology: protection class optimised for residential use

Emergency power & off-grid function

In the event of a power cut, the ELT-12 automatically takes over the supply to critical loads. This makes it ideal for households requiring a high level of supply reliability.

• Immediate switchover to off-grid mode
• Up to 18 kVA emergency power output
• Stable supply across all three phases

Remote configuration & support

The entire system can be conveniently configured remotely via the APsystems cloud platform (EMA). Firmware updates, diagnostics and settings can be carried out without a technician’s visit – ideal for installers and operators.

• Remote firmware updates
• Online monitoring of PV yield, consumption & grid power
• Cloud-based system management for installers
